The perimeter theory relating to the multifamily housing with inner court in Britain

二次大战后的20世纪70年代，英国出现了接受现代化住宅设计的先锋主义，对传统住宅设计意义上的功能主义进行了强烈的抨击。功能主义者主要从事无情的平行住宅布局。这种方法遵循格罗皮乌斯和勒柯布西耶的设计。但当时普通的住宅布局技术并不是以科学知识为基础的，而是一种技术。剑桥大学的《土地利用与建筑形态研究》从逻辑上揭示了住宅布局方式与密度关系的奥秘。他们对两种布局进行了测试比较，一种是遵循英国传统的村庄设计，另一种是现代化的住宅布局方法。人们对苏丹规划的社区应该是低密度还是像伦敦中心那样的高密度非常感兴趣。郊区的住宅大多设计在低密度。但一般的选择是为了城市性，设计师或建筑师努力寻找一种新的住宅设计方法，即住宅应具有与低密度环境相同的生活标准，并在较高的密度下设计。LUBF给出了一个很好的解决方案“周边理论”的主题。波拉德斯·希尔的住宅首次采用了这一理论来设计住宅的线条，其设计极具吸引力和影响力。这些人渴望一种新的生活方式，如节能或生态住宅，因此该理论的影响力比预期的要大。

Vanacularism accepting modernised housing design attacked very strongly against the conventinal functionalism in the sense of housing design in 1970's after World War ll in Britain. The fuctinalists worked mostly the ruthless parallel layout of housing. This method follows the Gropius and Le Corbusier's design. But the ordinary thechinique of the housing layout at that time was not based on the scientific knowledge but a kind of skill. The Land Use and Built Form Study of the Cambridge University revealed the secret on the relationship between the way of the housing layout and the density logically. They tested comparing the two kinds of layout one of which is designed after British tradition of villages the other one of which is just modernised method of housing layout. Then people were very interested in wheter the sudurban planned community should be low-dense or high-dense like in the center of London. Most of the housing in the suburbs were designed in the low density. But the general choice was for the urbanity and the designer or architects made effort to find a new method of the housing design which meant the housing should have the same living standards as the low-dense environment and be designed in the higher density. The LUBF gave a excellent solution "Perimeter Theory" to the theme. The housing Pollards Hill adopted the theory at the first time to design the line of the houses.The design were very attractive and influential. Those deys people aspired a new way of living like energy saving or eco-housing and therefore the theory had stronger influence than expected.
