Housing was traditionally constructed from building materials that could be obtained locally, such as timber, stone, earth, and reed, which created local vernacular building styles. Since industrialisation and transport improvements together with the decline of local sources of building materials, manufactured building materials have become available almost everywhere, resulting in a wide choice of construction options. However, there are still some locally preferred methods of construction determined by regional production and economic conditions. High-rise panelised concrete construction for apartments are common in the cities of Central Europe, lightweight prefabricated low-rise timber solutions are a feature of many Japanese, Australian and US towns and suburbs, while in situ concrete frame infilled with cellular brick walls is the chosen construction for all types of housing in Southern Europe and parts of the Indian subcontinent, and particularly in high-rise apartments in the high-density cities of the Far East. Masonry construction using bricks and concrete blockwork is a feature of Northern Europe and many parts of the Middle East and the Indian subcontinent. Earth construction for housing using adobe or rammed earth still persists in some African, South and Central American areas.
