Move over, Bilbo Baggins. Sometimes you see a home and the design/concept just takes your breath away. That's what we thought when we saw this 'underground' home located in the Swiss village of Vals, and designed by Netherlands architects at SeARCH and Christian Muller Architects. The striking stone house has a magnificent view of the Alpine mountainside through its long elliptical panel of windows, which also looks out onto a large entertaining area. The whole home is beautiful and unusual.
