Villa Vals

Dutch architects SeARCH and CMA designed this hillside gem with the environment in mind. Carved into the hillside near Vals (home to Therme Vals Hotel and Spa - another architectural gem) in Switzerland, you enter Villa Vals via an underground passage from an unassuming barn...lucky because you could miss that beautiful curved façade if you were skiing overhead. The light-flooded concrete interior features natural stone steps, and an abundance of Dutch design including the neon colour pops from Scholten & Baijings as well as those dining chairs and all that lighting. The best bit is you can stay there!
