Defining 'social' + 'affordable' housing in London today

London was an early laboratory for the development of social housing, and the city features a wide variety of architectures and financial models. The first social homes were built in the 19th century by philanthropists and the city's first public or 'council housing' was the Boundary Estate in Shoreditch, East London, created in 1890 by the LCC. The project began a movement towards public delivery and management and, over the course of the 20th century, local authorities all over the UK eclipsed housing associations and other charities to become the main providers.
