This underground home, located in the village of Vals Switzerland, is set in the middle of a group of mountain homes and if you do not look carefully you might miss it. Design of underground home, home plans are unusual collaboration between the architect and the Netherlands in Search of Christian Muller Architects. The most striking thing about this stone house is a magnificent Alpine view through the wide, open ellipse on the hillside, shows extensive outside entertaining area leading to the main entrance of the house. Circular opening in the mountains allows for many windows, which flood the interior with natural light while framing a stunning mountain view. Another entry from a nearby warehouse lead residents and visitors through underground channels, providing an alternative entrance to the house.
