A city famous for its rapid growth and high cost of living, London is not a place one immediately associates with social housing. Yet the British capital has a long history of such projects: from Henry Roberts' works for the Society for Improving the Condition of the Labouring Classes in the nineteenth century to the con-temporary, RIBA-award-winning Dujardin Mews. This guide by urban planner Tjerk Ruimschotel focuses on the developments in this often-overlooked field, beginning at the close of the nineteenth century and finishing at the present day. Icons such as the Barbican are included alongside lesser-known works.
