Tegia da vaut – forest lodge, Plong Vaschnaus, the citizens' community of Domat/Ems, Switzerland

It was important to the architect that the white fir trees used for the furniture were cut during the same moon phase as those used to build the lodge. The remaining timber was therefore to be shaped to make the seats and backrests. As the white fir does not really bend well, Girsberger's timber buyer carefully selected the planks to be used on site at the sawmill and coordinated the demanding process with the woodworking company. In the meantime, the frames had been formed from raw iron tubes, bent in its own metal workshop, welded and then fixed to the sawed wooden parts.
