For architects that specialise in the green belt, sustainability is not an architectural trend, it’s the heart of their business. They employ a conscious approach to energy and ecological conservation in designing every space,for future generations. The UK’s pattern of piecemeal review through Local Plans (driven by increasingly onerous housing targets) is not strategic and is patently unable to make rational decisions on the future shape of the city. A common misconception is that green belt is designated because or its landscape or other intrinsic value, but in reality it is a planning designation that has little bearing on the actual quality of land that is being protected from development. The aim of green belt architecture is to create sustainable development, which meets user's needs, without compromising design quality. Many practices also undertake research to inform and underpin their projects with an emphasis on the city and urban issues, with people first.
