AGROSCOPE consolidates the agricultural research of the Swiss national government on a rural site in Posieux in the canton of Fribourg. Intended to promote good public relations, the new facilities entail an auditorium, library, and restaurant, and according to the program of the open call, should be exemplary ecologically. Considering these criteria, the proposed project features walls made of straw bales as well as wooden ceilings. In this way the wall thickness is emphasized and developed in the sense of the spatial solid of the plan poché. The result is an intriguing contradiction in that the supple material straw evokes a building typology conventionally executed as massive stone construction. The leitmotifs of this architectural experiment comprise exemplary ecology in conjunction with fantastic layouts of the floor plans.
