The developments which occurred in Dutch public housing before 1940 have previously been described mainly in relation to architecture. The administrative, business and technical aspects have been hardly considered. These aspects include the experiments in building houses in concrete instead of bricks which were carried out shortly after the First World War. The starting point for the present study is the best known of these experiments, the Amsterdam neighbourhood of Betondorp, the origins of which are described in Part I. In Part II, after a general introduction about the use of concrete in architecture and public housing and a review of similar projects in Germany, Great Britain and Belgium, the other experiments in the Netherlands are discussed. .
