Housing project

Public housing may be a form of housing tenure in which the property is owned by a government authority, which may be central or local. Social housing is an umbrella term referring to rental housing which may be owned and managed by the state, by non-profit organizations, or by a combination of the two, usually with the aim of providing affordable housing. Social housing can also be seen as a potential remedy to housing inequality. Some social housing organizations construct for purchase, particularly in Spain and to an extent elsewhere.

Although the common goal of public housing is to provide affordable housing, the details, terminology, definitions of poverty and other criteria for allocation vary within different contexts.

The origins of municipal housing lie in the dramatic urban population increase caused by the Industrial Revolution of the 19th century. In the large cities of the period, many social commentators, such as Octavia Hill and Charles Booth reported on the squalor, sickness and immorality that arose. Henry Mayhew, visiting Bethnal Green, wrote in the The Morning Chronicle:

... roads were unmade, often mere alleys, houses small and without foundations, subdivided and often around unpaved courts. An almost total lack of drainage and sewerage was made worse by the ponds formed by the excavation of brickearth. Pigs and cows in back yards, noxious trades like boiling tripe, melting tallow, or preparing cat's meat, and slaughter houses, dustheaps, and "lakes of putrefying night soil" added to the filth.

Some philanthropists began to provide housing in tenement blocks, and some factory owners built entire villages for their workers, such as Saltaire in 1853 and Port Sunlight in 1888. It was in 1885, after the report from a Royal Commission in England, that the state first took an interest. This led to the Housing of the Working Classes Act of 1885, which empowered Local Government Boards to shut down unhealthy properties and encouraged them to improve the housing in their areas.
