Coin Street Community Builders (CSCB) is a social enterprise and development trust which seeks to make London's South Bank a better place in which to live, to work and to visit. CSCB has transformed a largely derelict 13 acre site into a thriving mixed use neighbourhood by creating new co-operative homes; shops, galleries, restaurants, cafes and bars; a park and riverside walkway; sports facilities; by organising festivals and events; and by providing childcare, family support, learning, and enterprise support programmes.

CSCB is a company limited by guarantee established by local residents in 1984 following a campaign against large scale office proposals. The company is controlled by a Board, elected by CSCB members. Only people living locally can become CSCB members. The Board employs staff to manage the company on a day to day basis. Profits are not distributed but are ploughed back into CSCB's public service objective.

Coin Street Secondary Housing Co-operative (CSS) is an Industrial Provident Act Society registered with the Housing Corporation as a social landlord. It was established by individual members of CSCB in 1987 and assists in the meeting of housing need by promoting, developing and supporting housing co-operatives. It provides advisory, training and management services to housing associations.

Coin Street Centre Trust (CSCT) is a company limited by guarantee registered with the Charity Commissioners. It was established by individual members of CSCB in 1987 and currently oversees the Coin Street family & children's centre. In the future the Trust will also offer a sports and leisure programme from the public swimming and indoor leisure centre being planned as part of CSCB's Doon Street development.

Coin Street Community Builders, Coin Street Secondary Housing Co-operative and Coin Street Centre Trust have agreed a shared set of aims and objectives to guide their activities.
