目前,在英国对于这种工厂化预制建筑部件,现场安装的建造方式,早已广泛应用于英国的建筑行业。例如,几乎所有新建的低层住房都会使用工厂化预制屋架来搭建坡屋顶,还有工厂化预制的木结构墙框架系统也被广泛采用。但对于此类的建筑及其建设方式并没有统一的命名和范围界定。为区别于传统现场建筑方式中采用预制部件的普遍方式,业内惯例通常将现场施工的工程量价值低于完工建筑价值40%的建造方式,称为非现场建造方式(Offsite Currently, in the UK, on-site installation of such factory-made prefabricated building components has long been widely used in the UK construction industry. For example, almost all newly constructed low-rise housing uses factory prefabricated roof truss to build sloping roofs, and factory prefabricated wooden wall frame systems are also widely used. However, there is no uniform naming and scope for such buildings and their construction methods. In order to differentiate the common way of using prefabricated parts in traditional on-site construction methods, it is common practice in the industry to reduce the amount of construction work on site to less than 40% of the value of the completed construction, known as Offsite
