Villa Vals is an all-equipped underground vacation home that was designed by Bjarne Mastenbroek and Christian Müller, respectively of the architectural offices SeARCH and CMA. Their design plan was to completely integrate the villa into the landscape to avoid disturbing the unspoiled nature. That is why access to the villa is only possible via the nearby wooden Graubünder shed, through an underground tunnel which runs straight through the mountainside.
The facade of the house is slightly slanted, adding to the view of the mountain scenery across the valley opposite of the house. The house, which was completed in 2009, was built and furnished in cooperation with a large number of Dutch designers and companies that produce Dutch design. Their willful designs fit well in the spacious, industrial architecture of the villa.
