Reusing by transforming the existing conditions into small certainties put together by interfering in what is not yet clear, the open house traces a possible itinerary through the swiss landscape and shapes, by means of precise fragments, intuitions and details, a possible chain of associative architectures. The existing becomes the entrance of the open house, defined along the way by the presence of stairs and walls, drawing a non-linear platform necessary for a new way of living. Circulation becomes the public space par excellence, opening the way to a shared territory, dealing with the question of housing by making the whole public. Thus, landscape becomes a way of understanding, living and picturing the environment rather than an idealized, decontextualized and commercialized cultural heritage, where the territorial raumplan addresses the domestic landscape. By its presence, the prominent building is there to take position, its ultimate goal being an environment of intermediary places, thresholds clearly defined, aiming to turn everything into architecture. Ultimately, the territorial raumplan grows and leaves the units to organize the whole in a collective sequence formed by the addition of autonomous parts, engaging architecture in new events. Drawings become the laboratory for studying a new way of inhabiting the swiss garden, architecture being its primary concern.
