All thanks to the tory government Really?
"In 1919, Parliament passed the ambitious Housing Act which promised government subsidies to help finance the construction of 500,000 houses within three years. The 1919 Act - often known as the ‘Addison Act' after its author, Dr Christopher Addison, the Minister of Health (a member of the Liberal and Labour parties). It made housing a national responsibility, and local authorities were given the task of developing new housing and rented accommodation where it was needed by working people...
The Addison Act provided subsidies solely to local authorities and not to private builders. Many houses were built over the next few years in 'cottage estates'. The Housing, &c. Act 1923 (Neville Chamberlain Housing Act - Conservative) stopped subsidies going to council houses but extended the subsidies to private builders...
In the immediate post-war years, and well into the 1950s, council house provision was shaped by the New Towns Act 1946 and the Town and Country Planning Act 1947 of the 1945–51 Labour government. Simultaneously, this government introduced housing legislation that removed explicit references to housing for the working class and introduced the concept of "general needs" construction (i.e., that council housing should aim to fill the needs of a wide range of society). In particular, Aneurin Bevan, the Minister for Health and Housing, promoted a vision of new estates where "the working man, the doctor and the clergyman will live in close proximity to each other"...
For many working-class people, this housing model provided their first experience of private indoor toilets, private bathrooms and hot running water, as well as gardens and electric lighting. For tenants in England and Wales it also usually provided the first experience of private garden space (usually front and rear). The quality of these houses, and in particular the existence of small gardens in England and Wales, compared very favourably with social housing being built on the European continent in this period...
The 1951 Conservative government began to re-direct the building programme back from "general needs" towards "welfare accommodation for low income earners" The principal focus was on inner-city slum clearance, completing the job that was started in the 1930s. Harold Macmillan's task, as Minister for Housing, was to deliver 300,000 houses a year. These were 700 square feet (65 m2), 20% smaller than a Tudor Walters Bevan house, usually built as a two-bedroom terrace called "The Peoples House". From 1956, with the Housing Subsidy Act 1956 the government subsidy was restricted to only new houses built to replace those removed by slum clearance, and more money was given to tower blocks higher than six stories. With this subsidy, neighbourhoods throughout the country were demolished and rebuilt as mixed estates with low and high-rise building. At the same time the rising influence of modernist architecture, the development of new cheaper construction techniques, such as system building (a form of prefabrication), and a growing desire by many towns and cities to retain population (and thus rental income and local rates) within their own boundaries (rather than "export" people to New Towns and "out of boundary" peripheral estates) led to this model being adopted; abandoned inner-city areas were demolished, and estates of high-rise apartments blocks proliferated on vacant sites. Whole working class communities were scattered, and the tenants either relocated themselves to neighbouring overcrowded properties or became isolated away from friends in flats and houses, on estates without infrastructure or a bus-route...
The last major push in council home provision was made under the Wilson (Labour) government of 1964...
Laws restricted councils' investment in housing, preventing them subsidising it from local taxes, but more importantly, council tenants were given the Right to Buy in the Housing Act 1980 offering a discount price on their council house. Proposed as policy by Prime Minister Margaret Thatcher and carried out under the remit of Secretary of State for the Environment Michael Heseltine, the Right To Buy scheme allowed tenants to buy their home with a discount of 33–50% off the market value, depending on the time they had lived there. Councils were prevented from reinvesting the proceeds of these sales in new housing, and the total available stock, particularly of more desirable homes, declined..."
Social Housing and the NHS, both built by Labour!
