This article considers the public and voluntary sector relationship in hous
ing provision from an historical and social science perspective. It pays pa
rticular attention to models based on markets, hierarchies and networks and
presents an overview of voluntary action and state intervention In English
housing since 1900. The article focuses on housing agencies with charitabl
e status, and on three periods - pre-1914, the 1950s and the 1970s. For the
first two periods, the emphasis is on the William Sutton Trust, England's
largest house-building charity. In the latter period, attention shifts to S
helter, founded in 1967 and the most successful of the homelessness chariti
es. In these case studies, the role of the courts, charity commissioners, g
overnment legal officers, Ministries responsible for housing, parliament an
d local authorities are discussed. The importance of attempts to politicise
charity law and charitable status throughout the twentieth century is unde
rlined. Central government is shown to play a significant part in this proc
ess, legitim ising its preferred response from local authorities and volunt
ary agencies. A hierarchical interpretation of state Intervention is temper
ed, however, by stressing the significance of unintended consequences atten
ding central government's successive interventions in housing provision.
