Plain and systematic planning ended up revealing its limits. Landscape now appears as a better scope to envision cities development since it forces the reflection to take into account both an anteriority and a geographical context. It softens the ideology associated to the creation of cities and the gap between the study scale and the duration of urban phenomenons, a few months studies being supposed to offer directions for decades to come.

The idea of natural environment plays a fundamental role. To abstract and inescapably uncompleted geometric axes, we prefer the movements of Geography and the spontaneous lines of agriculture to guide - when necessary - the forced development of the city.

The cities we truly love built themselves, like landscapes, with more collective intelligence than planning. The landscape design approach aims at finding some of this inspiration by suggesting the landscape dynamic as an urban development model.
