The roof structure of the kindergarden in Riehen has it all: It is unequally inclined on all sides, like a pyramid whose peak has been trimmed with a slight slope. The task of HP Gasser AG was to design and install suitable roof lights for the trapezoidal openings. And all this without on-site dimensional control! The planning on the computer with 3D models was correspondingly challenging. State-of-the-art CNC technology made it possible to cut the construction parts precisely. The viewer notices little of this finesse: Neither window frames, window sashes nor the motors for the ventilation are visible to him.
