Résumé : Today, new residential building is inserted into a complex economic circuit. This circuit involves different well-known actors (project manager, land owner, mortgage society, architects, building contractors and the public sector). Each one of them has an impact on new residential morphological characteristics by means of its strategy and its logic. The purpose of this paper is to analyse these strategies in the case of Belgium with a particular attention to the link between strategies and residential urban pattern. This analysis underlines the important historic role played by the public sector. This sets back the public sector in the centre of the debate around a future sustainable land planning policy.
