The history of aided self-help housing, that is, of housing built with state assistance by families for their own use, is largely unknown. There is a widespread misapprehensionthat such a policy was first discussed and practised during the 1960s, in the context of the Third World. In fact, it was adopted in the Soviet Union, and in many European nations and cities, notably Vienna and Stockholm, after the First World War. During the 1930s it was incorporated into homestead schemes, and praised, on both sides of the Atlantic. Then, for a time after the Second World War, it was widely debated and adopted in many of the more advanced industrial societies. Unlike public housing or market-oriented policies, aided self-help never had strong political or ideological associations. In one sense this was a strength: at different places and times, it was endorsed from all sides of the political spectrum. In other respects its detachment from parties and ideologies was a weakness. It was not promoted by any political constituency, and aroused opposition from the building industry and trades. At best aided self-help has sometimes filled, and at the worst it has slipped through, the cracks in state housing policy.
