In former West Germany, more than one in three residential buildings are singlefamily homes built between 1949 and 1978, amounting to 22 per cent of all housing units. Today, considering the lifecycle of these buildings and current socio-demographic trends, their viability looks uncertain. As the population ages and birth rates decline, demand for single-family homes is waning. In addition, different lifestyle choices among the newer generations are leading them to prefer different types of housing.
