Architecture, Building and Structure Design Rheder 2 Weekend House by Heike Falkenberg 'Life in and with Nature' is the basic motif for the Haus Rheder, located directly on the Nethe River. The two completely glazed facades, one of which can slide almost completely open on the river side, blur the boundaries between interior and exterior. Reduction to the quintessential was the focus: light, air and tranquility. The design plays skillfully with the elements: a reflecting pool causes natural light reflections to develop on the ceiling, while a fireplace brings fire into the room. The highlight, however, is the terrace with a wide view into the surrounding landscape.
