In contrast to traditional urban planning, the urban planning of the city is based, as far as the office is concerned, in the first instance on the present landscape or rather on the cultural-historical, geomorphological, water managaging and ecological qualities of a place. The load capacity of the existing landscape is leading and decisive for the housing and parking program and the method of access. The main landscape structure provides a spatial framework within which new and contemporary forms of habitation, possible other urban programs and access can be developed and integrated.

Water management forms an important and structuring basis for the urban development plan. By reintroducing, retaining or strengthening the natural hydrological system of retaining, storing and draining rainwater and using it as a structuring principle, a zone is created naturally in an area of ​​intensively and extensively designed areas. Intensive zones, which are suitable for housing, possibly other urban programs and infrastructure, and more extensive zones, where the drainage can be organized and there is room for the development of ecological qualities and recreational co-use.
Such an approach leads to strategic and conditional plans rather than compositional plans. The focus is on pre-investment in the landscape framework, after which the implementation can gradually follow.
This gives the plans a certain degree of flexibility; flexibility in pace and phasing of the interpretation and flexibility in the program.
The time factor is used in this approach as an important planning factor. From the study of the development history of an area, a new layer of time is added and the continuity or memory of the place is restored. And not only with regard to spatial aspects, but also with regard to social and economic aspects; in short, regarding the atmosphere of a place.
