NIMBY Urbanism and Landscape Urbanism

Hundertwasser's design for Spa Blumeau increases the urban area while allowing a vegetated landscape to develop

The most popular urban design policy is NIMBY Not In My Back Yard: lets keep on building but lets do it somewhere else. This may change when we all come to see the Earth as our Back Yard. Meanwhile, how can we make urbanization more popular? There are about three times as many humans on earth today as on the day I was born. If this trend continues, as is projected, we need a lot of space for urban sprawl or we need to intensify the use of each square meter which is already urbanized. How can either policy be popular? My suggestion is asking landscape architects to study plots of land and  find ways of simultaneously (1) creating more indoor space (2) creating more greenspace which is both useful and accessible to the public. This can be done in lots of ways and one of the best examples comes from the work of the Austrian artist-designer Friedensreich Hundertwasser. At Spa Blumeau, illustrated above, he took some tired farmland and made a popular spa with, I guess, more wildlife and vegetation than before the development took place.

See the Landscape Urbanism Blog and Wiki on Landscape Urbanism Landscape Urbanism is a theory of urbanism which argues that landscape, rather than architecture, is more capable of organizing the city and enhancing the urban experience.

Urban forestry and landscape architecture

In addition to being beautiful, the trees and gravel in the Place des Vosges are good for microclimate, wildlife and hydrology.

All good foresters know that tree planting must serve multiple objectives: beauty, timber production, habitat creation, water management, public recreation, carbon cycle re-balancing etc. Urban landscape architects, on the whole, are less enlightened. Too often, they think of tree planting as decorative activity akin to the placement of public art in cities. Urban foresters should broaden their horizons, as rural foresters claim to have done.

Acoustic noise barriers and sustainable landscape architecture

Would residents and drivers rather have the acoustic noise or the visual noise?

Would residents and drivers rather have the acoustic noise or the visual noise?

Flickr has a good slection of photographs of noise barriers – but not many of them are structures one would want to have at the foot of one’s garden, except perhaps for the purpose of reducing noise nuisance. The Wiki entry on noise barriers states simply that: “A noise barrier (also called a soundwall, sound berm, sound barrier, or acoustical barrier) is an exterior structure designed to protect sensitive land uses from noise pollution.”  It’s not enough. Noise barriers should also contribute to other objectives and help make ‘new landscapes for our new lives’ (Nan Fairbrother) which are beautiful, sustainable, microclimat, ecological etc. If sustainable landscape architecture is to have the glorious future it deserves, the results must be beautiful as well as useful. For more information on the landscape treatment of noise barriers see:  Environmental Noise Barriers by  Benz Kotzen Colin English.

SUDS LID WSUD Urban Drainage Systems and landscape architecture

SUDS Sustainable Urban Drainage is a UK term, equivalent to  LID Low Impact Development is the US  and WSUD Water Sensitive Urban Design in Australia.

SUDS, LID, WSUD have come a long way since I first came across the idea, about 20 years ago (see Chapter 9 River engineering, channelization and floods). But it is a pity that it remains dominated by engineering concepts. Of course the  engineering is important, but the idea also has poetic and visual aspects which are rarely explored, except by Herbert Dreiseitl’s Waterscapes practice. Have a look at the Flickr groups on Sustainable Urban Drainage Systems and SUDS. The designs are very worthy but, except for the traditional ‘craft’ examples, they lack design inspiration. Most of the ideas hover between wartime economy furniture and a boy scout aesthetic. Then look at the CIRIA website’s treatment of SUDS. Only a whiff of wildlife saves the ugly concrete detailing from prison architecture. The illustrations from America’s Low Impact Development Center are better without coming anywhere near the Dreiseitl standard. If sustainable landscape architecture is to have the glorious future it deserves, it must be beautiful as well as useful.

Saana Pavilion at the Serpentine Gallery

The Saana Pavilion would be EVEN more beautiful with water and bamboos, instead of white chippings and trad flower pots

The Saana Pavilion is the most beautiful, so far, in the Serpentine Galleries series of Summer Pavilions, but it is a disappointment for no fault of the architects. Obviously, it should have been integrated with an equally brilliant  garden design.

The Online Etymology Dictionary has this for Pavilion: 1297, “large, stately tent,” from O.Fr. paveillun (12c.), from L. papilionem (nom. papilio) “tent,” lit. “butterfly,” on resemblance of wings. Of unknown origin. Meaning “open building in a park, etc., used for shelter or entertainment” is attested from 1687. Saana have done the butterfly idea to perfection and it integrates with the plane trees better than any of its predecessors. But it could have been so much beautiful if integrated with, for example, water and bamboos. I hear the pavilion has been sold, so perhaps I will visit a garden some day and find this has been done. I hope so.

My suggestion to the Director and Trustees of the Serpentine Gallery is that they move heaven and earth, in their customary style, to raise additional funding for a combined pavillion+garden and then invite entries from integrated professional teams. This would:

  1. easily outdoo the best designs at the Chelsea Flower Show, which are often architecturally disappointing (see design reviews of Chelsea Flower Shows and Haruko Seki’s 2008 Silver Moonlight Garden)
  2. attract many extra visitors and far more media coverage, because gardens get far more media attention than buildings
  3. match the etymology of ‘pavilion’ as a building integrated with its setting
  4. achieve the wondrous goal of encouraging indoor and outdoor designers to work together on every possible occasion
  5. in all probability, make a series of contributions to the cause of sustainable green design

The Serpentine Gallery has a better opportunity to promote garden and landscape design than any other gallery in London: the Serpentine itself was once a leading-edge design. I think it is one of those occasions when an opportunity becomes a duty.

Context: Skyrise, highrise and surprise

gold-coast-skyrise-q11Increasingly there is a trend towards the design of skyrise buildings in the inevitable push skywards which is the fascination of architects [and city fathers] worldwide: why? Because we can.

Beyond the temptations of exploiting the limits of technological possibility are a number of very real concerns about context which architects should be mindful of.

Each building contributes to the visual amenity and character of the urban fabric….and in the case of cities, located as Surfers Paradise, is on the edge of a spectacular coastline….to the landscape setting and ecology.

Each building’s context is unique. So there are no hard and fast principles applicable in all circumstances. [Truly great designers delight in confounding principles…so with some risk I say] Some general principles do apply in relation to the general impact of the height of a building on its context.

For example, a generous open landscape setting such as is present on the Gold Coast in Australia, visually permits a correspondingly generous height of built form. And a predominantly vertical city fabric is little impacted by an additional vertical built form – even if it breaks the previous skyline limits. However, this is only to say something of the visual impact of such developments. And of course there are many other considerations, not least being the impact of shadows etc on the useability of both the surrounding buildings and the surrounding streetscape and landscape.
