British urban planning laws and regulations starting in the 19th century, but until the 20th century, the 1960s, before the beginning of the comprehensive reflection of urban planning practice, the focus of urban planning from physical planning to exploration of the Social Sciences; to the end of the 20th century, with the development of more new city, the focus turned to the thinking on economic issues, to ensure that urban development projects under the market economy smoothly. Since the middle period of the eighties of the twentieth century, accompanied by a British soaring land prices and housing demand increased sharply, housing planning system corresponding to further improve the assessment of housing market demand, to evaluate its feasibility under the background of market economy has become the general policy housing planning process. So, planners, architects, real estate analyst (surveyor) and landscape designers together to become an integral part of the planning process in a key role, real estate development professional, and many British universities have also been incorporated into the Department of urban planning in one direction.
Good urban planning and urban design should has its economic feasibility, and meet the social and economic development needs, and promote the development of urban economy, and bring the corresponding social and environmental benefits. England is one of the most densely populated regions of Europe, so Britain imposed strict urban planning control, to improve the urban development densities become in recent years the British urban planning especially the hot issues on the planning of housing. In order to achieve the sustainable development of urban construction, planning should achieve social ecology — — win win win of economy, lack of social and environmental benefits of economic demands does not conform to the requirements of sustainable development. The premise of British housing economic evaluation of planning is to ensure that planning can meet the needs of social development, and in a certain extent, improve the living environment and living quality. Economic benefit itself involves two aspects: direct economic benefits of investment projects in the development process, and through the social and environmental benefits and non-direct economic value added.
Due to the implementation of city planning in the United Kingdom than the United States and other European countries are more stringent, so pay more attention to the formulation of science and the implementation of the feasibility. In the planning of housing, follow the law of the development of urban economy, considered qualified urban planning or urban design should the market demand, residential development costs and profits into consideration. On the other hand, development, promote the realization of housing planning, development gains become economic evaluation is one of the most important link, thereby affecting the process of planning and space efficiency.
Economic evaluation has two aspects of macroscopic and microcosmic. Micro level assessment of the key lies in the development of the planning and design is brought directly to the profits, thus ensuring the healthy operation of the market supply chain; macro level evaluation is more complex, often including social and environmental benefits are likely to bring direct economic benefits, such as social justice, community activities, high-quality community environment brought about community and economic benefits added value. From the housing demand to assess profitability, is a from the macro to the micro, from the social demand to the planning and design to construction and operation of all aspects of participation and collaboration. Different professional division intertwined to form a relatively complete economic evaluation framework.
