The dynamism of landscape & lighting

Following my recent blog on Light, time and landscape, my good friend Paul Nulty of Nulty+ has written this response:

In his guest blog post, John Wyer (landscape designer and friend of Nulty’s) effuses about the dynamism of a landscape – not just through the changing seasons, but also with the passage of daylight. As a lighting designer such dynamic lighting inspires me, from the dappling of sunlight through woodland canopies, to flat, overcast light enhancing the greys of bark on deciduous trees.

When you consider how a landscape is constantly evolving and how the hierarchy of space becomes different under differing lighting conditions (artificial or natural), it becomes important for any landscape designer to capture the essence and hierarchy within the environment, and it’s great to read John acknowledge this.

Of course, artificial light excites me – it’s a medium with huge influence on the perception of landscape and placemaking. I previously discussed the impact of artificial lighting in my blog post “Light Time Economy”, so I won’t dwell again here. However, when it comes to light, we must make sure that not only is the right ambience captured, but that the right hierarchy is also presented.

This requires careful, strategic planning of even the smallest space. In the same way a landscape designer will carefully consider the size and mass of planting to create focal points and permeability, the lighting designer will use light to create contrast and drama to create focal points, depth, foreground, midground and background.

It’s very easy for artificial light to create a whole new perception and visual composition of a space, providing alternative focal points and balance than those achieved under daylight conditions.

Collaboration between landscape and lighting designer is imperative as there isn’t necessarily one way to light a landscape. We need to consider the seasons when planning an installation as shape, texture and colour will change. Certain light sources will emphasise different tones within the living landscape – tones that are ever changing, for example, highlighting the warmth of autumnal leaves or the blue/silver hue of a bare tree in winter.

We also need to give care and attention to the type of hardware used as some luminaires work more efficiently in different temperatures – what works in winter, may not in summer. It’s also wise to choose outdoor lighting that has a long lamp life for minimal maintenance.

A considered, holistic approach is also wise, and more often than not, less can actually be more. What isn’t illuminated is often as important as what is. I sometimes imagine “painting the space with light” when thinking about what should and shouldn’t be lit. And often, with less foliage, we require less light, or perhaps a focal point may shift from one end of the garden to another.

Landscape lighting for informed architects and developers has become as much a part of new home design as say, a good staircase. At the very least, entrances, steps and pathways are now tastefully and safely illuminated under the guidance of a lighting designer – we know the importance of how to highlight the areas of beauty and downplay the not-quite-so-beautiful parts. This also extends the internal spaces beyond the “window”, which would otherwise appear as a dark, reflective mirror. Drawing the eye beyond the interior to the garden extends the feeling of space.

It’d be amateur to say that “one size fits all” when lighting a landscape. Whether it’s a tiny suburban patch or acres of rolling parkland, if the use of light is well considered then there’s a clear opportunity to extend the use, view and ultimately connection with our outdoor environment. However, it needs a gentle touch and the expertise of a skilled lighting designer working hand in hand with landscape architects and garden designers – like John and his team at Bowles & Wyer – to make sure that light isn’t simply added on or considered at the end, but forms an integral part of the planning process, to truly capture the landscape’s aesthetic from season to season.

Urban Bad: Rural Good? Notes from my presentation at the European Landscape Conference

Hongkong_central_kowloon-fullIf you play the word association game, and ask someone to come up with the first word that enters their head when you say ‘Urban’, surprisingly enough, the answer is not ‘Ecology’ in much the same way as if you say to someone ‘European’, they do not say ‘Landscape Conference’. If you put ‘Urban’ into Google, this is the image that comes up as number one.

 

In fact the first two hundred or so images are nearly all either glossy (shiny glass, steel, night shots) or gritty (traffic, graffiti, urban decay). People make brief appearances here and there. Urban parks make their first entrance – actually the first representation of a tree – at image number 46. At around number 240, a subtle shift occurs and ecology, water resources, and urban agriculture not only all make appearances but then feature strongly in the following returns. It is almost as if when you ask people to think of urban, they first think of the non-human aspects, then the human – side and finally natural features. So clearly, we tend to think of cities as dense, built environments, with people coming second and the natural world coming in somewhere way down the field. And yet despite this, as recent studies have shown – iTree amongst them – London is 52% green or blue with most other UK cities doing at least as well if not better.

The left hand photo of Central London show as much green as grey; this of course shows some of the more affluent parts of the city. Indeed the word ‘Leafy’ is synonymous with affluent. In fact, as the right hand picture shows, the green/grey ratio holds up pretty well across the urban grain.

street trees per km LondonLook at this map of London – it shows the density of street trees. The interesting thing about this is that apart from the obvious – fewer trees in the city of London for example – there is no clearly predictable pattern, which suggests it is more about policy than topography or other factors.

 

In fact, the relationship between gardens, ecology and landscape is not only very old; it is intrinsic. What is the oldest garden you can name, other than the Garden of Eden? The answer is of course the hanging gardens of Babylon. Cities came about with the development of organised agriculture, on a scale which allowed specialisation. This in turn led to spare time and resources for elites. Gardens, both public and private, were a natural and inevitable development. These are well documented in Mediterranean and Middle Eastern cities, but also in China and South/Central America. Although medieval cities were often very dense, during the C18th and C19th, cities began to develop a more intentionally porous character. Garden squares, church yards and left over market gardens all became absorbed into the urban grain.

Everyone's dream house?
Everyone’s dream house?

During the C20th, the emergence of the Garden City movement in Hertfordshire, Merseyside, Birmingham and London added a new dimension to these public spaces.  For the first time, private gardens en masse became a feature of cities and laid the pattern for modern suburbia. It was everyone’s dream to have their own house, with their own front door and their own garden.  Of course, private gardens can be rich and diverse ecosystems.

The more we pack into a garden the richer the biodiversity.
The more we pack into a garden the richer the biodiversity.

Gardens are per se good, but the more diverse the environment, the richer the ecosystem. The less we intervene, the better: untidy is good. So, in many ways this suburban movement has brought advantages for ecosystems, but as the density of development has increased, all too frequently what we end up with is this: *. Tiny patches of grass and slabs with no shrubs or trees, and a sterile ecosystem. There is a strong argument in favour of creating even higher densities, and combining them semi-public communal spaces. This allows the creating of meaningful chunks of dense landscape for everyone to enjoy. Look at these examples from Darbourne and Darke’s work in the 1960s that I took on a recent visit to the Pimlico estate.

And yet recently, in city centres we seem to have lost the plot completely. When it comes to public space, we frequently end up with Sterile spaces. An endless recreated pastiche of about four elements that you will all be familiar with: box hedging, black granite or basalt, plane trees, sterilised water features. In London, a city driven by money and commercial power, the primary goals of restoration are twin (and linked) aesthetic, and return on investment.

I think this (From Niemann & Schadler; ‘Post Industrial Urban Strategies’, 2012) neatly sums it up: “It might be that the deficits in frequently criticized modern urban design practices are less related to the quality of individual buildings but rather in the neglect of gaps and the spaces in between them.” There is an interesting unintended double meaning from the word ‘neglect’ there, for it is indeed when we neglect spaces that the best results sometimes happen: just as we create better ecosystems in our gardens by intervening less, I am fascinated by what happens when we do nothing. Left to its own devices nature does a pretty good job. Transport corridors for example, left virtually untended have been shown to have a much higher value for wildlife (particularly pollinators) than surrounding land, even where that land is low intervention agriculture. Often, the most interesting urban landscapes have occurred spontaneously in post-industrial environments, and some of the best approaches celebrate this rather than seeking to wipe it out and replace it with sleek granite and water features. Perhaps the most celebrated in recent years has been the Hi-line, because the way that it threads through communities catches the imagination. But for me, the Landschaftspark Duisburg-Nord by Pieter and Tilman Latz is really interesting.

Tim Collins (interventions in the rust belt: the art and ecology of post-industrial space, 2000 ) suggested some good guiding principles:

Post-industrial public space should:

  • Reveal the legacy of industrialism, not eradicate it or cloak it in nostalgia; create images and stories, which reveal both the effect and the cause of the legacy;
  • Unveil social conflicts in the city, not repress them; create works that illuminate and explicate conflict and points of dynamic change;
  • Reveal ecological processes at work in the city, not eradicate them; build infrastructure which embraces ecosystem processes and a philosophy of sustainability;
  • Enable an equitable community dialogue, which envisions a future; produce new forms of critical discourse, which provide access, voice and a context in which to speak.

permaculture-wordleWhich brings me on to permaculture. What is permaculture? It started from a principle first put forward by a New Zealand ecologist, Bill Mollison (and his student David Holmgren) who noticed that the greatest amount of useable biomass in terms of food was produced by multi-layered complex ecosystems such as forests. It has long since expanded to cover a whole philosophy of life and way of thinking. One of the interesting things about permaculture is its understanding of the importance of edges. Edge is king – the rougher the edge, the better. It is also worth looking at some of the more celebrated examples of brownfield site use along permaculture principles – Cuba.

Cuba went through an almost complete socio-economic collapse in the early 1990s when the subsidised oil for sugar deals came to an end with the implosion of the Soviet Union. It lost 34% of its GDP over a fairly short period. Pesticides and artificial fertilisers were unavailable. All land was pressed into [organic] agricultural production, particularly in urban areas. Although many of these Organoponicas no longer survive, some still occupy the derelict spaces between buildings in meanwhile use. The benefits are huge. Apart from the obvious ecological and environmental ones, there are also community, education, food production, as well as health and well-being (you can read more about some of these Cuban Gardens in another post on this blog here). These principles can and are being applied throughout Europe and America. Anarchism and Community action have led to some exciting developments. Allotment 2014-10-23-14_30_10I am a trustee of a community Garden in my home town of Hitchin, near London. We simply took over a forgotten nettle-bound corner of the park: *, and after some initial suspicion from the local authority they are now enthusiastically behind the project. Fifteen years later, it now runs a community garden, two allotments and a resource building, employs several people, grows vegetables in several different projects with people with learning difficulties and runs sessions on wildlife, growing produce and other subjects. Community action should not be underestimated as a way of producing sustainable results. You can read much more about the Triangle community garden in another post on this blog here, or by visiting www.TriangleGarden.org)

IMG_5618So what of other edges? How can we ‘roughen up’ the edges of built structures? Well’ clearly ‘green cloaks’ are one option. Living walls, green roofs, etc. are all important and have a role to play. They cool buildings in the summer and insulate them in the winter. They reduce runoff, decrease CO2 both actually and in terms of emissions, have been shown to lower pollution levels, they provide food sources and increase biodiversity. A recent project at the south bank centre combines both – retrofitted ‘green roof’ on concrete terraces, run by a community garden and used by the public.

 

I was on Waterloo Bridge recently; as I walked across my pace slowed and I drew to a halt and gazed around. Of course it is virtually impossible to walk across that bridge without looking at the view, but what really struck me was not the undeniable grandeur and panorama of the city, or the sense of history laid out before me. It was instead the sense that the river is the forgotten part of all this. It is a truly wild thing flowing through the heart of a civilised city, which the bridges do no more than span. Jens Haendeler, a student working for me has come up with a novel solution for boosting diversity in river environments. Basically it is a system of crates containing a filling which can be populated (either directly or indirectly) with aquatic plants and fauna. This is the sort of creative thinking which we need to apply.

Concluding, I have included some shots (taken on my mobile phone, so forgive the quality) on a 15 minute walk along a canal through NE London last week. In a short stretch, many of the principles that I have talked about are demonstrated.

It will require action by all of us as professionals not only to design the positive responses to urban situations, but to consciously create spaces in which spontaneous reaction by either nature or community can occur.

These are opportunities, not problems to be solved.

The Lancasters – from genesis to realisation

 

View Looking east websize

As this project has recently received some press and won the UK Society of Garden Designers Award for Public and Commercial space, I wanted to share something of the design process, particularly as it is an unusual design.

We were approached by Northacre PLC in 2008 to advise them on proposals for a new property they had acquired near London’s Lancaster Gate. It was the surviving arm of what had originally been two identical terraces, and was divided from Bayswater Road by a garden approximately 120m long, but only 15m wide. The building had a fine stuccoed façade – said to be the longest continuous stucco façade in Europe – which lent a flamboyant feel. it reminded me straightaway of the grand promenade buildings in Brighton, where I had often stayed as a child. But here, instead of facing out to the sea, the stuccoed façade looks over Hyde Park.

When I began to research the history of the building, I discovered that the architect was a big fan of French architecture and had indeed been influenced by the grand hotels of the Corniche in Cannes. I discovered an early stereoscopic photo of the development, taken just after it was built and the street trees were planted in the 1850s. Before that, it had been pleasure gardens for a long time, so it seemed appropriate to recreate gardens there again. As well as this flamboyant character, the building had something of the self-assured solidity of the Victorian era: confidently decorated and built to last.

A design started to emerge in my mind. I started leafing through books of late Victorian patterns – stylised leaf and flower forms in swirling motifs. We developed a design based on these motifs – cut up, blown up on the photocopier, twisted and repositioned so that they rippled down the length of the garden in an undisciplined, freeform parterre. to give a vertical link with the building, and as a nod to the Corniche at Cannes, I placed a series of 6-8m fan palms along the back of the garden, punctuating the façade of the building. The design was finished, now all I had to do was convince the client. I made an appointment and turned up at the developer’s office. I sat in the meeting room with the head of architecture, the chairman and the development director, and went through the presentation I had prepared, slowly telling the story before showing the final plan. A long silence. “Absolutely f@#*ing brilliant” the chairman said slowly in his strong Swedish accent. Then he called the whole office in (nearly 40 people) and made me go through the whole thing again. In the end, they based the marketing of the development around the landscape and used the palm trees as the logo for the development.

Getting it built was another matter. How on earth to translate a drawing like this into a scheme? Eventually after much discussion, we decided to pre-form all the complex shapes in steel, so that they could then be planted as a box parterre on site. This worked OK, particularly as there was some flexibility in actual positioning of them. The next problem was the build-up over the roof slab. To start with, we had a 300mm drainage blanket of gravel to act as attenuation. Then beneath the planting, following advice from Tim O’Hare, we had layers of graded washed sand topped with a layer of rootzone material. This was a sand-rich growing medium with good drainage properties and some added fertiliser and organic matter. The whole lot was free-draining, non-compacting and well aerated. We insisted on test certificates for everything. All the specimen plants were pre-tagged and we had a short-list of nurseries that contractors could buy the other material from.

The final result was just as we had envisaged it. It was a long wait to see it finished, but it was worth it. There was no doubt that the constant support of the client was a major factor in realising the scheme.

Why do developers think that garden designers are sexier than landscape architects?

There have been a number of high profile projects in London recently where developers have employed garden designers. This is nothing unusual, you might think. But in actual fact it is a departure from traditional practice, and quite an interesting one.

Firstly, the projects are not ‘gardens’ as such (see my post on ‘When is a Garden Designer a Landscape Designer’ for more details on this and for definitions of what a garden actually is). Most of them are in the semi-public or public realm – parks, squares, pedestrian spaces between buildings, etc.

Secondly, this is traditional territory for landscape architects. In the past, the likes of Gillespies, Capita Lovejoy, Townsend and the like would generally have undertaken these sorts of projects. However, if the client wanted someone high profile, they would have perhaps engaged a ‘rock-star’ landscape architect such as Martha Schwartz, Kathryn Gustafson or perhaps even Eelco Hooftman of Gross Max – all from outside the UK, you will note (although many practice here).

The large (non ‘rock-star’) practices are still very much engaged in the public realm – more so than ever. One doesn’t hear much about them however. And perhaps therein lies the key to what is going on here. To use developer-speak, they are not ‘sexy’. Dan Pearson, on the other hand, is sexy (forgive me please Dan!); as are Andy Sturgeon, Christopher Bradley-Hole and Tom Stuart-Smith. All are gold medal winners at the Chelsea Flower Show, which receives more TV coverage than any annual event except Wimbledon and all are therefore household names, to a greater or lesser extent.

So is it that developers simply want some of this ‘brand’, some of the glamour of Chelsea to be associated with their developments? That probably accounts for a lot of it. Branded ‘products’ are appearing more and more with developments. Interiors by so-and-so, architecture by practice X (although often only the concept) and so on. But if that is so, then perhaps a more interesting question is why are there no ‘sexy brands’ in landscape architecture. Why is it “Gardens by Dan Pearson” and not “Landscape by Townsend”. I would argue that it is a systemic problem with landscape architecture in the UK. Ever since landscape architecture emerged as a self-made idea, it has hitched itself to architecture. In the UK this meant mimicking the RIBA – copying its structure, professional values, procurement strategies – although inevitably always a step or two behind. However, as a result the public has failed to distinguish landscape architecture as a separate profession. It is almost as if the landscape profession puts on its dustiest jacket to go to the professional party. Even the name is confusing. the two individual words are perfectly understandable to people, but together they don’t really make a sensible meaning – is it really the architecture of landscape? Or perhaps it is just the landscapey bits of architecture (there we go again…). Now garden design, on the other hand, what could be clearer? To make it worse (or perhaps illustrating my point) many landscape architects really look down their noses at garden designers.

So what is it that distinguishes the landscape professions from all the others? The answer is that we work with plants. Paving, levels, external space, all of these things can be and often are done by other professions; though often less successfully in my view. Those Latin names though – that always gets them! Planting design is a specialism in itself, and one that most landscape architects don’t do often enough to excel at. Garden designers on the other hand often come into the profession through the planting door. Sometimes I think that this is exactly why landscape architects look down on them. To be fair, many garden designers are not very good at all the other stuff.

Of course the ultimate irony is that most of the garden designers who are taking on public realm work employ landscape architects in their practices to help them implement the projects – because they have a better technical knowledge. Sad then, that landscape architects are basically seen as good technicians, but not as creatives.

One question that remains hanging is that of aftercare. Perhaps you have already read my other articles about maintenance of public landscapes (‘The whole life cost of a Citroën‘ and ‘The great divide … north/south? or capital/maintenance?’), but if not, then my point here is that there is no point in designing something without making sure that the resources and skills are there to care for it. Dan Pearson is famously careful about this, as are Argent Estates, his ultimate client at Handyside. But it is a point to consider: garden designs need gardeners to look after them. So is it the case that if developers employ landscape architects, they get something boring, but if they employ garden designers, they get something exciting? Maybe, but it’s a moot point. However, the truth is that in most cases, what garden designers deliver is still garden design, which may be unsuitable for the public realm resources. It will be interesting to see how it pans out in years to come.

 

Shark-infested waters? (or how to survive in the top end of the residential development market – and enjoy it)

The development market has a reputation for being cut throat and being populated by swaggering macho developers who only care about the bottom line. Is it really as bad as that? In the thirty years or so that I have been involved in this market, that hasn’t entirely been my experience. Sure, it has it’s share of predators like any other market. But despite that, I have found most developers to be personable and intelligent.

The stakes are high though – these are often for properties valued in the high millions. Because of this, sites are densely developed, which in turn leads to all sorts of technical and logistical problems. So this is not a market for the timid, but there is plenty of opportunity.

Croc
Typical developer? Not in my experience…

The first step is to understand the client. What are developers about? Are they all greedy, short-sighted individuals who only care about the profit? Do they all have enormous egos? Will they always go for the cheapest option? Of course not. Instead they are (mostly) ordinary people trying to build something of value, although admittedly they are perhaps more comfortable with risk than most of us! My first rule of thumb is:

  • Give them what they need rather than what they want. Most developers may not understand what is available –they may know more about property than you, but you know far more about landscape than them. They will probably base their expectations/ideas on what someone else did on their last project. This can be very frustrating, particularly if they act as though they know everything. However: this is your chance to shine and show how much better than the opposition you are. Go beyond their expectations – surprise them!

Pavilion, St Johns Wood. A scheme that met the client’s brief, but exceeded his expectations.

But to do this, you must have a least a basic understanding of how the development process works. Let’s look at some of the background. First, funding for development.

  • Funding – how does it work? Most people have the idea that it is all a developer’s own money behind a project. In fact, it has always been the case that developers have sought the majority of funding from banks and other institutions. In the (good/bad?) old days, it used to be possible for developers to get funding for about 80% of a project. Often, this would be calculated on the basis of final value. Given that the market would be rising and that a developer might expect to make a margin approaching 20%, this would mean that he (for it is mostly men) could get all the costs funded by loans and pick up the profit at the end. And then came the credit crunch!
    It's all about the money?
    It’s all about the money?

    These days, it is a lot tougher. A developer may have to find a much bigger chunk of the land purchase costs himself. After that, he is still likely to be looking at having to find about 45% or so out of his own pocket. This means that on most projects there are co-investors, which can make the client a somewhat multi-headed beast. The bank will also have monitors in place (generally surveyors) who look after the funder’s interests and make sure the project progresses smoothly and with minimal risk.

Funding is only part of the story though; planning also plays a critical role (as with any development).

  • The role of planning. No project can progress without local authority planning consent. Although this may seem like a fraught process and just another headache, it is actually a significant business opportunity. Few schemes can expect to get a smooth path through planning without at least some landscape input, especially on sensitive sites. This means that a commitment to a comprehensive landscape scheme can be built in to the project plan from the beginning. It’s also your opportunity to dazzle the client with your design skills and understanding of the market! The first stage is generally before the application. Initial discussions with the planners (‘Pre-app’) will often include some landscape material. The main application will almost always include a landscape plan an other drawings. It is important to make proposals that are affordable here, but not driven solely by budget. You have leverage over the client here as he will want to get planning, but push him too far and you will not be popular. there will generally be other consultants involved in this process as well, often guided by a planning consultant. Once planning is achieved, the next hurdle is ‘discharge of conditions’. Normally when a scheme is granted planning consent, certain conditions are imposed, one of which is usually landscape. Before that section of the work can be started on site, the planning condition needs to be discharged with detailed drawings, samples etc. There is quite often a gap between consent and discharge, with the scheme having moved on in the meantime. The planners will be looking to make sure that there is no watering down of the proposals, but some deviation form the detail of the original is normally accepted.

The Lancasters – a good example of how we achieved quality in a difficult contractual situation. Stock was all pre-tagged, testing certificates required for all the fill materials and followed up by a rigorous site inspection programme.

Although the production and release of information is generally driven by the planning process, there will be other times when detailed information needs to be produced, mainly as a case of integrating the landscape design with other parts of the development. Perhaps the most important thing however, is how to ensure that your designs are translated correctly into a polished landscape. For a lot more detail on how we achieve this, best to read my blog post ‘How do you deliver quality in a project’ posted in March 2015. However – here is a potted guide:

  • Control of process and quality. Clearly the most important tool to ensure quality is good documentation. The quality of the drawings and specifications are critical. They should be clear and concise, as detailed as they need to be – that is they should have enough information for someone to build the scheme without improvising, but not so much that they become snow-blind! Once you cede control of the decision-making to site staff, you cede control of the quality of your scheme. That is not to say you can’t draw on their experience and expertise, but make sure you define the things that are important. Poor drawings and spec are the biggest complaint from contractors. Planting material is often difficult to specify accurately to achieve really good quality. for this reason, we often persuade clients to spend a little extra and pre-tag key items. Nurseries will generally hold stock for a period between detailed design and installation. The client does not own this stock, so there are no contractual complications, but all the tenderers have to go to the same source. Beyond this, we also use a rigorous process of insisting on samples of materials and workmanship, testing certificates (especially for soils), certified sources and so forth. We are terrier like in this, because it sends a message about the level of quality we expect elsewhere and means that contractors do not try and take short cuts. Finally, make sure you have sufficient fees for inspection. The client will expect you to visit the site on a regular basis during the construction process – indeed you will need to for your own sake to ensure quality.

Which brings me on to the final point – pricing. You need to be realistic on this. bear in mind that stages may be widely spaced – it is not unusual to have a gap of 2-3 years between enquiry and completion on these sorts of projects, sometimes longer. Your fees will need to take account of this as well as the myriad meetings you will need to attend. But in any case, in this market it is much better to compete on the basis of quality, not price; so don’t be shy!

This was first delivered as a lecture at the Landscape Show in late September 2015.

Urban (notes from the SGD Autumn 2014 conference)

If you put the word ‘Urban’ into Google image search, this is what comes up:

Central Kowloon in Hong Kong: glossy, sleek urbanism.

A glossy, sleek, landscape of steel and glass. Actually, I think that many people’s idea of Urban is grittier, more individual; maybe even a little threatening. Something more like this:

The truth is more interesting. Landscape and Urbanism are intimately linked. If you ask almost anyone what is the earliest example of garden design they can think of, they will probably say (other than Eden) the hanging Gardens of Babylon.

This is the only one of the seven ancient wonders of the world to have no known historical location, although it is almost certain to have been in what is now Iraq. The important point is that the very concept of gardens emerged at the same time as Urbanism. Cities only became possible because people moved from a nomadic hunter-gatherer existence to one of settled agriculture. The idea of making gardens emerged at the same time – gardens and buildings are inextricably linked; so one could argue thatwithout cities there would have been no gardens.

Medieval cities were pretty dense – look at southern European examples that still survive. The same was true in a more haphazard way in Northern Europe, where wealth came later. Significant green urban spaces only began to emerge here with the Agrarian and then Industrial Revolutions, and the explosion of learning that came with them. Buildings began to be taller, partly because of new building methods. Larger scale developments began to emerge, along with ideas of urban design and town planning. These higher densities created value which effectively funded green spaces between the buildings: much of central London with its squares was built in this way. I love this image of Belgrave Square, a chunk of woodland surrounded by a dense urban grain:

This trend continued into the twentieth century. Look at this wonderful example of Urban design from Darbourne and Darke in Lillington Street, Pimlico. This was the project that inspired me to go into Landscape Architecture in the 1970s. Once again, the buildings justify (or perhaps are justified by) the landscape spaces between. Is this buildings in a landscape or landscape between buildings?

We have tried to follow this route with our own work. Look at this example of dense Urban development in St Johns Wood, below. It is easy to grasp the scale of the space and the way it is shoe-horned (over an underground car park) into a sliver of land between new houses and the back of the adjacent C19th houses.

And finally, Singapore. Some of you might remember from James Wong’s barnstorming presentation at the ‘Exotic’ conference in spring 2014 his fantastic images of ‘greened’ urban development in Singapore:architetcure-parkroyal-sky-garden-hotel

Here, they seem to have the daring to achieve the sort of things that British Cities achieved in the Victorian era. In our own way, we are still making daring statements in London, such as this huge living wall on the Rubens Hotel designed by Gary Grant.

This tied in very neatly with one of the co-sponsors of the conference, Treebox, whose system for living walls has the lowest water and nutrient usage of just about any on the market.

Perhaps the biggest challenge in Northern Europe though is how to deal with the post-industrial age. Nature has its own way of doing this of course. Look at this picture of a deserted, derelict Aldgate East tube station:

Duisberg in Germany (by Latz and Partners) is the best known of these post industrial landscapes. Here the gutsy nature of the industrial structures was retained rather than being sanitised, and a series of contemporary uses was found for the former steelworks.

Partick Cullina explored this more fully in his fascinating presentation on the New York Hi-Line Park. This landmark project came about through the intervention of residents when the structure was threatened by demolition, and a design competition was staged. It was won by a Briton, James Corner, a graduate of Manchester Poly like me. There is no doubt though, that the real success of the project is Piet Oudolf and Patrick Cullina’s subtle herbaceous planting.Herbaceous planting on the Hi-Line

‘Grand Projets’ have their place here too, and there is room for both these and the post-industrial renovations like the Hi-Line. Dan Pearson and Thomas Heatherwick’s Green Bridge project in London promises not only to be a fantastic structure and addition to London’s skyline, but also a major regenerative engine in its own right.

Mudchute FarmHowever, cities are as much about anarchy and the individual as government (perhaps more so?). So within the city grain there is room for outbreaks of individualism. I love London’s city farms such as Mudchute. Who could ask for a better picture than this:

There are also hundreds, thousands, hundreds of thousands of tiny back gardens, each crammed with plants and artefacts in an orgy of individualism and biodiversity. James Fraser’s anarchic gardens perfectly represent the importance of small interventions. These are perhaps more important for the ‘green life’ of a city and together make up the mosaic that is its true character. Here we can all play a part, and particularly the garden design community. Sue Illman talked passionately about the way water (as an issue) links all landscape spaces. How we manage water resources and how that influences the design decisions we make, thus becomes very important. She mentioned CIRIA and its C697 paper (downloadable for free) as a particular resource in this respect, and although some of the thinking has expanded a little since then, it is still a useful source of information.

The true nature of cities therefore begins to emerge; far from being sterile hard environments, they are as much made up of a network of vegetated spaces running through and between the buildings. In fact, more than 50% of London’s area is either ‘green’ or ‘blue’ (water). If we go back to aerial photographs, look first at this picture of Central London, and then one of the whole of London.

It is noticeable from these just how green the London is; it is not just the capital however, Manchester, Sheffield, Bristol, Glasgow and many others are just as green. The world’s largest urban horticultural survey (iTree) was undertaken in London this summer in an attempt to quantify cost and other benefits accruing from trees in the city. And there are many; look at the map below of the density of street trees in the London boroughs from the GLA website. What comes through is not only some of the surprising boroughs (like Southwark, with 50 trees per km of street) but also how haphazard the pattern is: it does not follow the ‘green doughnut’ that one would expect. Investment makes a real difference here.street trees per km London

 

I think what was remarkable about this conference was that at a day devoted to ‘Urban’ we spent the whole time talking about plants and nature. Our most important actions are to create the framework; nature will do most of the work thereafter. Indeed, one of the most interesting threads to emerge from the day was the way in which all the speakers worked with rather than against nature. Sue Illman’s rain gardens, Patrick Cullina’s planting on the Hi-line, James Fraser’s forest gardens and Dan Pearson’s carefully poised plant communities all had the underlying principles of permaculture in common. As Patrick Cullina pointed out, our interventions are important but they need to be finely balanced.

Could landscape architects’ skillsets be more widely applied?

The ‘conservatory’ on the fourth floor of the Barbican is an unusual place for the Landscape Institute to hold a party, but last night it was rammed with Landscape Architects from all ends of the profession. Was it was an inspired choice? The brutalist architecture countered by the Tetrastigma, Ficus benjamina and other seventies throwbacks gave a neat if somewhat outdated reminder of the relevance of landscape and an interesting contrast to one of the themes of the evening – the 300th anniversary of Capability Brown. Some might argue that the 1970’s was not landscape architecture at its finest.

What interested me though was a second theme that emerged from the evening. In his ‘acceptance’ speech Noel Farrer (the incoming president) spoke of the great work done by Sue Illman (the outgoing president). As most people know, Sue’s area of expertise is water – SUDS, water sensitive urban design and the like. Noel mused on the way that Sue’s use of a single theme – water – was able to illustrate potential weakness in almost any issue, whether it is urban design, agriculture, global warming or transport.

Water of course connects all issues, especially those around biological (including human) activity. It is the connectivity and life force carrier of all biological systems.

Afterwards I was speaking to Jason Prior, a friend from college days. Jason trained as a landscape architect, but these days runs the built and external services section of Aecom, an international services company. He has around 10,000 people working for him – structural and services engineers, architects planners and of course some landscape architects. I asked him what he thought his training as a landscape architect brought to the job that others would not have. His answer was – “An understanding of systems”. An interesting answer. I thought about this: structural engineers are principally problem-solvers; services engineers design systems, architects (whilst doing a bit of both of those) design objects. Landscape architects on the other hand design frameworks which are then populated by systems and biological components. Although we also have our share of object design and problem-solving, it is this ability (or necessity?) to see the wider picture that makes landscape architects unique amongst design professionals. Not only do we design with time in a way which no other professions do, our projects are actually designed to change and develop as time passes. My guess is that the bigger the scheme, the truer this is.

So the question remains, are these skills under-utilised? Does landscape architecture provide a training – or state of mind – for more widely applicable skill-set? If so, how can the profession market itself to be taken more seriously, more widely. Perhaps we should leave it to Noel Farrer to answer that one.

Bunhill Fields

Smooth, sweeping paths through the remembrance garden

About a week ago, I was in London for a day of appointments. With about 45mins to spare between meetings I took a stroll through Bunhill Fields. For those of you that don’t know it, this ancient Graveyard just outside the old City of London walls has been a burial site for at least a thousand years. Amongst the 123,000 people known to have been buried there before it was closed for interment in 1854 were many famous literary and non-conformist figures from the nineteenth century including Daniel Defoe, William Blake and Susanna Wesley.

A plan of Bunhill Fields including Peter Shepheard's improvements

Anyway, so much for history. I had scurried though this space on a number of occasions before – indeed our office used to be located close by when we first started up. This time however, I tarried a little and discovered something that fascinated me. After the Second World War, Bridgewater and Shepheard were engaged to carry out improvements to the graveyard. Peter Shepheard, who was one of the leading young landscape architects of his generation, re-planned the memorial gardens to the north part of the site.  The work is unmistakeably English and of the post war modern movement. Peter Shepheard’s great strength was the effortless simplicity of his designs. Like many of his peers, he was completely comfortable with the Edwardian arts and crafts heritage, and did not see it as a millstone in the way that later generations did. The smooth lines of the Yorkstone path, edged with brick sweeps confidently through the grass beneath the huge plane trees that define the space.  In contrast the [relatively] small orthogonal beds with evergreen shrubs, Liriope, Vinca and other plants typical of the period are a pleasantly restrained contrast. The use of fallen gravestones is both practical and I would argue reverential whilst giving a nod to the history of the site.

Perennial planting edged with gravestones.

I have fond memories of Peter (as he liked to be known) or Professor Sir Peter Shepheard PPRIBA, PPILA, as he was when I knew him (there were probably a few other letters that I have forgotten.) He was an modest man, full of stories of his colourful career. I was lucky enough (with Chris Bowles) to work on the restoration of Charlston Farmhouse. We also worked on Winfield House (in Regents Park) and a few smaller projects. I particularly remember Peter’s wonderful pencil sketches and his plans, all in pencil and filling the sheet completely to the very edge with a sort of evenness of texture and graphic. As well as having a keen understanding of space, he was also a master of herbaceous planting  (unusual for someone who had trained initially as an architect).

Peter Shepheard’s confident use of materials demonstrates an understanding of past and present.

Perhaps we have something to learn from the gentle and unselfconcious blending of style shown here. Have we really learnt so much in 65 years?

 

Are Garden Cities the World’s End?

I recently went to see ‘Worlds End’, the final part of Edgar Wright’s ‘Cornetto Trilogy’. For those who don’t know it, the film is a science fiction comedy, the third in a short series of action films starring Nick Frost and Simon Pegg. I saw it in Letchworth, in the Broadway cinema. Why is this relevant? Well, Letchworth forms the backdrop to most of the movie; it was filmed there and indeed the Broadway Cinema was one of the locations in the film (‘The Mermaid’). 

The first Garden City has long been held up as the apex of good urban planning, including by the current government, so it was interesting to see it used a somewhat sarcastic comment on Britain today. As Peter Bradshaw put it in his review of the film for the Guardian: “It is different from the locations that usually show up in movies: London or the leafy countryside. This is New Town Britain, Visitor Centre Britain, the suburban commuterlands and hinterlands: bland and agreeable.” The film is multi-layered, but one of the underlying themes is that living in the suburbs turns you into a robot. Hardly a new message, but ironic that they chose to illustrate this by using the crucible of the garden city movement, whose principle aim was to counter the way that industrialisation had de-humanised people.

Regular readers of this blog may remember my post from last year – “Where have all the trees gone?” (http://www.bowleswyer.co.uk/blog/?p=132). In this, I began to explore why many developers don’t really plant trees and how this might be addressed. I followed it up with a lecture at a conference in Devon (staged by the excellent Barcham Trees) in which I postulated that the garden city movement was indeed a turning point in modern planning, but it was also where it all started to go wrong. I pondered on what it was that made particular housing estates ‘successful’. For the moment, let’s ignore esoteric or academic definitions of success and instead look at market or colloquial definitions. The most expensive, the most sought after areas of housing are dominated by something larger than the houses – trees. And not just any trees; large, mature, forest species – horse chestnuts, oaks, planes trees, limes, even sycamores. So clearly, green leafy suburbs are what we aspire to. In fact estate agents and the media frequently use the word ‘leafy’ as a synonym for affluent when they are talking about neighbourhoods.

Belgravia - typical leafy Victorian upmarket London

If we trace the roots of housing development back 100 years or so ago, we come to the genesis of large scale housing development the garden city movement. Before that, during the Victorian era, most development had been urban. At both ends of the social scale, mass housing as a concept had really only come into being at the beginning of the C19th, with developments such as Bath and the Nash terraces in London for the wealthy and mass terraced housing for the working class. But the rise of a middle class in late 19th century England meant that a different demand started to emerge. The landed gentry wanted their town houses to be elegant and urban – gardens were not a part of that. The working classes could only afford back to backs. Whilst the middle classes could pay more for housing, they could only afford one house. What they hankered after was mini version of the country estate. Both the architecture and the gardens point towards this – half-timbered houses evoking an idealised view of Elizabethan country houses; lawns, which had previously only been the reserve of the very wealthy, became available to all with the invention of the lawnmower in the C19th.

The dream...

The garden city movement pulled many of these threads together. It distilled elements from the arts and crafts movement (with which it was closely allied), social reform (particularly of the Quakers), town planning, and mixed all this with a heady dose of social idealism with which all great reform movements are imbued. For me this is

...the reality

where it all started to go wrong. The fork in the road where it all seemed so nice led us after sixty years ago from Letchworth – pleasant enough, to some of the more horrible modern housing estates. One of the reasons that the Garden City idea was so popular was that it plugged into the

English Dream. But continual watering down of that dream has made it into something of a nightmare.

Meaningful space in Alexandra Road

In city centres, one clear way forward is to go back to a landscape-dominated high density development model. There have always been versions of this around – look at Darbourne and Darke’s Lillington Street for example (a social housing project for Westminster City Council c1961-62, and a beacon in early 60s architecture-landscape partnership), or Janet Jack’s landscape around the Alexandra Road development in Camden – one of the last great social housing schemes. I would argue that both these developments are relevant today, although Alexandra Road has suffered from poor maintenance. I first went to Lillington Street in 1977 – it was one of the things that caused me to choose to train as a landscape architect. I revisited the scheme more recently and it has fared

Lillington Gardens development by Darbourne and Darke

very well. It feels as fresh and relevant now as when it was first designed 50 years ago, although the trees are bigger! There is no vandalism, and although people do have small areas of defensible space, the overall quality of and scale of the landscaped spaces is such that the estate is really leafy (there it is again!) despite being very high density. The overall feel is (not by accident I am sure) similar to traditional London squares. These principles are applicable to smaller scale developments.

We have tried to use similar principles ourselves in design of dense urban housing developments. Admittedly, these were privately funded; I suspect that the days of well-funded grand (or even modest) social housing are over, at least for the moment.

The Collection, London NW8

Both the Collection and Tercelet Terrace developments adopt this approach of public landscape at the expense of private space. Actually, in both projects the cost of the landscape was a very small percentage of the total.

Tercelet Terrace London NW3. A development tightly stitched into the urban fabric.

What this shows is that the truth here is somewhat counter-intuitive: that in urban development at least, up to a point, higher density is actually a pre-requisite of good landscape and greater biodiversity, rather than acting as a restriction, as one might expect. It creates the opportunities for more meaningful spaces and often provides the funding to address those opportunities. The counter to this is that suburban development does not create good quality spaces, particularly at the densities mostly being built in recent years. Perhaps the government should apply more joined up thinking in this respect.

Rural development is another story – another post on that coming soon (or perhaps another movie?)

The great divide … north/south? or capital/maintenance?

I met up with some old friends a couple of weekends ago. Not just any old friends, but a 30th reunion of graduating from Manchester with our postgraduate diplomas in landscape architecture. As you can imagine, there was a lot of catching up to do. Lunch merged into dinner followed by a couple of beers as we put the world to rights. As we compared our working experiences over the last couple of decades, differences began to emerge and crystallise.

There was something of a north south divide – no real surprise there. Actually, this was more of a local authority/private practice divide than a north south, but it just so happened that most of the people working for local government were based in the north of England. Many of these people were disillusioned. My experiences of working for a local authority were exhilarating, but were thirty years ago. Not surprisingly, things have changed since then.

The great hedge-trimmer massacre - can this really have been the designer's intention?

The overwhelming theme seemed to be one of lack of funds and skills completely driving the agenda. Even when there was money available for capital projects, the complete dearth of maintenance/management funding meant that the design of projects was severely clipped to meet the skills and funds available. One colleague told me that she had been told to do only schemes with ‘trees and grass’ as ‘trees needed no maintenance and we can cope with the mowing’. Another told me of a flagship city-centre garden restoration scheme in the north of England that received funding. He spent some time working on the restoration – it was the best project he’d had in a long time – and it was installed complete with planting by a competent contractor. When he revisited it a year or so later, he described it as ‘The great hedge-trimmer massacre’. I’m sure I don’t have to explain what this means – I witnessed a similar thing on my way to work this morning. He has just taken ‘early retirement’ at the age of 56 and is going to work in the private sector.

A sad state of affairs.

The final irony was that we were having the last part of the conversation in a coffee bar in Piccadilly Square – which looked pretty sad. Most of you will know this as the recipient of a highly prestigious landscape scheme a few years ago as a result of a design by Tadao Ando and EDAW. It all had a rather tired unloved look. Some of the seeds of this were undoubtedly in the design – like the timber benches (see left), and of course all city centre spaces get well used and show the signs of wear, but given that this is Manchester’s ‘mantelpiece’ I had expected a bit more. This is a sad state of affairs indeed. You might recall that this is a bit of a pet subject of mine; I wrote a previous blog about it – ‘The whole life cost of a Citroën’ and also spoke at a recent conference on the subject – SGD spring 2013 conference

There are a number of lessons that emerge. The first is an obvious one – there seems little point in spending money on capital projects which are then not going to be maintained adequately. This is a downward spiral, because if future capital works funding is sought, but the evidence of previous schemes is unconvincing (because of poor maintenance) then bids are unlikely to be successful, or least that should be the case.

The second is a broader though parallel one on the design community. Why will practices invest time and care in projects that they know are not going to be looked after? This applies to commissioners as well – the effect is pervasive.

Finally, the whole process exerts a downward spiral on wages and profits in the landscape industry. Excessive profits at the expense of public bodies is clearly bad for all of us, as taxpayers. Nonetheless, profits are essential for re-investment in companies, for resilience, innovation, training and all the other things that make our industry great. Take this away and you end up with a sector made up of under-resourced, demotivated companies staffed by under-paid demotivated people. Hardly a good omen for the future.

The sad result of all this is that the industry is just reinforcing stereotypes and preconceptions that outsiders hold about it. Maybe some of the direct works departments of the 70’s and early 80’s were lazy, bloated and inefficient. But they were also great training grounds, fantastic centres of horticulture and beacons of local character. Has the pendulum perhaps swung too far the other way?
