In this article, the territorial aspects of the idea of tomorrow’s house are viewed from two perspectives; the theory of urbanism, and as a technical issue concerning the formulation of principles of a spatial policy towards the housing environment as well as respective planning techniques with particular reference to the code of practice developed in order to translate these policies into specific regulations and design guidelines. In planning practice, concretizing the general rules of a spatial policy requires a reference to structural urban units. However, while defining their properties in spatial planning documents, we ought to pay more attention to the relationship between the architectural and anthropological attributes of this category of urbanized space and its impact on the utilitarian values of a place of residence. The author also indicates some interdependences between the land use planning techniques, applied as environmental policy tools dedicated specifically to urban structural units, and respective policy statements used in socio-economic planning to guide housing development in accordance with strategic goals. Certain similarities between these strategies are presented as are such theoretical concepts as the architecture of the city, space syntax or the just city.
