For the housing industry today, the problems of the ‘Third World War’ (i.e. COVID-19) mirror somewhat those of the Second World War when the aim was to come up with a quick, efficient and modern answer to a problem. In 1942, it was the bombed-out housing crisis. This was when the UK took inspiration from the USA and their very advanced and modern prefabricated houses for workers and families working on huge dam construction projects. UK prefabs were temporary homes built in the factory – they were the MMC (modern methods of construction) of their day.
