这是瑞士建筑师Valerio Olgiati的一个混凝土作品—Plantahof 礼堂。礼堂位于Plantahof农业学校的新广场。立面上最高的那一面正对广场。面积270平方米，2010年10月完工，从设计到竣工历时两年。内部空间处于明暗交界的暧昧点。正对的两扇窗口定义空间并带来外面广场或另外一面山谷的景观。一根混凝土柱像支住帐篷那样支着这个深色混凝土建筑，同墙体形成整体结构框架。这是一个坚固并明晰表达设计理念和建造的建筑。礼堂是多功能的，可以容纳130—180个座位。除了常规使用外，还能举行研讨会，会议和小组讨论。

The placement of the new auditorium creates a new central square within the overall structure of the Plantahof agriculture school. The high façade holds together the new piazza.

The inner space of the auditorium lies in half-light.  Two windows facing each other define the inner space and allow for a view from the new piazza towards the axis of the Prättigau valley. A thin, dark coloured, concrete wall stretches over the pillars and beams like a tent. These elements are supported outside the building by the abutments. The structure combines in equal measure a frame and a solid construction. The result is a hybrid of pillars and walls, expressing an architectural concept and lending the building character.The new auditorium is multifunctional  and has a capacity of 130 to 180 seats. In addition to its conventional use, the new hall has the capacity to host different kinds of events such as seminars, congresses and panel discussions.
