The fallingwater project establishes precise relationships with the beautiful landscape of the Maggia Valley and in particular with the suggestive Bignasco waterfall, an element of great landscape value. The architecture, characterized by the horizontality of its main elements offset from each other, relates to the plain of the valley floor. The program is structured in strips parallel to the Maggia river, emphasizing the direction and natural flows present in the valley. In this way the recreational-tourist center separates the camper area facing the river from the large free outdoor space. The location of the building pays attention to the parsimonious use of the land and therefore leaves the large surface area to the east free for sports and leisure activities. The building is oriented with the main glazed facade towards the waterfall. In the summer season, the windows can be opened with the guillotine system to create a more direct and fluid spatial and functional relationship between internal and external space. The wooden beams of the roof structure are extended over the perimeter of the envelope to create large-scale pergolas, emphasizing the horizontality of the space, filtering the light and protecting the large windows.
