If, like the urban historian André Corboz, one accepts that there is a ‘point of view of the territory’, then the guide plan is an interpretation of the state of the place confronted with the programme, i.e. the creation of a regional centre in Bernex. The guide plan is based on the ingredients of the current territorial fabric, looking at the history of the formation of the territory: the relief, the hydrography, the vegetation, the road network, the land parcels and the buildings (the Bernex of today). The territory is “put to the test of the project”, it shows its capacity for transformation, and the project gives it a new meaning. Promenades take shape, a landscape structure is formed: a system of parks, tree-lined boulevards, a division into ‘neighbourhood units’ with the principles of their distribution, polarities of public spaces, a communal centrality, attention to the distance and the great landscape. The project allows us to grasp what we are dealing with, what territory, what programme. From then on, the process is underway: planning to understand, understanding to programme… This is the principle of the Bernex guide plan.
