Context-sensitive garden design

Ken Yeang, the world-famous Malaysian architect complains that ‘Pursuing a kind of national architecture is a dilemma imposed by foreign architects’. He says that the Americans and Europeans can’t do it ‘Therefore, why should we define a national architecture, but these developed countries cannot?’. He is wrong. The architectural style known as International Modernism is really a North European style which just happens to be widely used in a context-insensitive manner.

For garden design and landscape architecture there is a far stronger case for a context-sensitive approach. Countries, regions and small localities have different geology, different climates, different hydrology, different flora, different fauna, different histories and, above all, different ways of using outdoor space. So why on earth should there be an International Style of Garden Design? The only possible excuses are the general lack of professional education in garden design and, in the case of landscape architecture, the general ignorance and lack of interest in design theory.

Curiously, the nearest thing to an agreed principle of landscape architecture is that ‘designers should consult the genius of the place’ (the genius loci). It is a great principle. But it has to be carefully considered and ‘though the genius must always be consulted she does not always have to be obeyed’. What most designers do is take a quick glance at the local character, find out a little about soils, find out some more about climate – and then do what they planned to do in the first place. The people should shout them down.

Resin bound gravel

Resin bound gravel (left) and unbound gravel (right)

The University of Greenwich has re-done much of its paving with resin-bound gravel on its Maritime Campus. It has one the most scenic campuses in Britain and certainly needs to be ‘paved with care’. But was resin-bound gravel the best choice?

Some of the pedestrian paving, usually adjoining buildings, is done with a beautiful riven sandstone. It comes from Yorkshire and has the local name Yorkstone. This is an excellent material. Other pedestrian paving, often running through grass areas, is ungraded gravel. This too is a good choice, though it is hard to fathom why they used granite instead of the local flint.

Most of the new paving on the campus is resin bound and uses a small-diameter flint gravel aggregate (2-4mm). For the central roadway this was a good choice. A bitumen macadam basecourse supports the weight of vehicular traffic. But the road is used as much by pedestrians as by vehicles and it was well worth the extra expenditure on resin bound gravel to hide the bitumen.

But I can’t see the point of having used resin-bound gravel for purely pedestrian walks or for the new car parks: (1) it costs a lot more money (2) it is impermeable and therefore works against Sustainable Urban Drainage System (SUDS) objectives (3) it does not have that nice crunchy sound you get from gravel (4) it looks phoney – like a plastic imitation of gravel (5) it is out of keeping with the historic character of the Maritime Campus – where unbound flint gravel is the traditional material.

What is the difference between garden design and landscape architecture?

Residential garden design - or landscape architecture?It’s worth looking to see what Wikipedia and Britannica have to say on this question. And I have to say that the Wiki entry on landscape architecture is a lot more useful than the Britannica entry on garden and landscape design. Britannica only let you have a quick glimpse at their text before a big black screen tries to sell you a subscription. But you have enough time to discover that the text is badly written garbage. Here is a sample: “Efforts to design gardens and to preserve and develop green open space in and around cities are efforts to maintain contact with the original pastoral, rural landscape. Gardens and designed landscapes, by filling the open areas in cities, create a continuity in space between structural urban landscapes and the open rural landscapes beyond. ”

The Wiki entry ( at 10.40 GMT on 1.7.2008) is so much better, or at least so much closer to my own view, that I suspect the author of having made good use of the website. It states that: “Both arts are concerned with the composition of planting, landform, water, paving and other structures but: (1) garden design is essentially concerned with enclosed private space (parks, gardens etc), (2) landscape design is concerned with the design of enclosed space, as well as unenclosed space which is open to the public (town squares, country parks, park systems, greenways etc)”

Compared to Europeans, Americans tend to be a bit sniffy about garden design. They see it (as in the Britannica quotation above) as a subsection of garden design. This makes garden designers inferior people, because they can only do a fraction of the work undertaken by landscape architects. The American Society of Landscape Architects (ASLA) only introduced a professional award for garden design, actually called “residential design” in 2005: ” The ASLA 2005 Professional and Student Awards program features a new category—Residential Design—drawing more than 120 entries in its inaugural year. Cosponsored by Garden Design magazine, awards in this new category will be presented on Monday, October 10, during the ASLA Awards Ceremony. A special luncheon honoring all award recipients, their clients, and professors will be held following the ceremony.”

Personally, I see garden design as much closer to a fine art than landscape architecture. Art is for art’s same and gardens are for garden’s sake. Landscape architecture is often for a public or private body with a shedful of axes to grind. It is similar to the distinction between painting and graphic design or between sculpture and product design.

Towards a Greener London

Green carpet, green chairs and green light - seen on London's South Bank on 12th July 2008As the author of a an old report on Towards a green strategy for London, I should be pleased to see a sudden and dramatic green turn on London’s South Bank. And I am. Green is a good outdoor colour, kind to the eye and calming for the nerves. But I would also like the Greater London Authority to adopt a serious Green Strategy for London. ‘

Landscape architecture on the march

Marching for landscape architectureCongratulations to Whitelaw Turkington for sponsoring a landscape contribution to the London Festival of Architecture. A group of landscape architects marched through South London on Saturday 12th July 2008, carrying trees and with periodic pauses to consider the relationship between trees and London. Congratulations also, to one of the firm’s principals for becoming a tree bearer.

It is always good to see landscape architects on the march. But I wonder if they don’t need more political courage. Way back in 1983, I proposed to the then-chair of the Landscape Institute’s South East Chapter, that we should protest against the failure of the London Dockland Development Corporation (LDDC) to commission a Landscape Strategy. The proposal was that every landscape architect in London should keep their Christmas tree until it went brown. We would then carry the dead trees in procession from the Palace of Westminster to the HQ of the LDDC, cast them down and, should anyone be so brave, light a funeral pyre.

I wish we had done it. Although there are a few good things, the landscape planning of the Isle of Dogs is predominantly disastrous. Had they spent a few pence on a landscape plan, the cost of the re-development would have been significantly lower and the environmental quality would have been significantly higher.

Plant combinations and planting design

Bad advice on the beauty of gardens

Having long believed that good plant combinations are a key to successful planting design, I was pleased to get a copy of The Encyclopedia of planting combinations by Tony Lord and Andrew Lawson (Mitchell Beazley, 2005). They are both expert photographers and Tony Lord, who wrote the text, is a former Gardens Advisor to the UK National Trust. Unsurprisingly, the photographs are excellent – if not quite as excellent as one might have expected. Disappointingly, most of the text is about the individual plants. Since there are many books on individual plants, this could have been omitted. The plant descriptions are followed by remarks on plant combinations and, as one might expect from a pair of photographers, they have a good eye for line, colour and texture.

The most surprising thing about the book is the appalling standard of the introductory section on ‘The art of combining plants’. It reveals the author to have no understanding of garden design as a fine art and somewhat reminded me of books written in the 1920s. Take the opening statement as an example: ‘A garden’s beauty invariably comes from the plants that it contains, the way they work together, and the overall effect they produce’. Does this apply to the Alhambra, to Versailles, to the Taj Mahal or to Rousham? Of course not. A garden is a composition of five elements: landform, vegetation, structures, water and paving. If one element is strong and the other four are weak you will not have a truly great garden.

After this blinkered introduction, the first sentence is ‘Making a successful garden is a question of balancing what is already there with what is required of the plot’. But what IS ‘required of the plot’. The author does not say. The second section (p.13) opens with the sentence ‘Once any hard landscaping is in place, selection of the plants can begin’. Goodness gracious me! You should not employ a gardener when you want your central heating fixed – and you should not employ a horticulturalist when you want a design for your garden. Similarly, the UK National Trust should employ horticulturalists for horticultural advice and garden designers as gardens advisors.
