There are however many EU directives that do apply to housing construction and design, but these directives do not directly affect the inter-EU modular home sector due to inter-EU free trade considerations . However, each modular home is legally expected or obliged to be integrated into the local building regulations once the final construction is finished . </P> <P> In the United Kingdom the word' prefab' is often associated with a specific type of prefabricated house built in large numbers after the Second World War, such as Airey houses, as a temporary replacement for housing that had been destroyed by bombs, particularly in London . </P> <P> Despite the intention that these dwellings would be a strictly temporary measure, many remained inhabited for years and even decades after the end of the war . A small number are still in use in the 21st century, but more and more are being demolished . In 2011 it was announced that Britain's largest remaining prefab estate of 187 homes in Lewisham, South - East London, is to be redeveloped except for six homes . </P> <P> Prefabs were also built in the First World War such as the still occupied houses in Austin Village, Birmingham . </P>
