Crazy on the outside, yet classy on the inside, the Solo House project by TNA Architects for Matarrana, Spain looks highly unstable, but one must never judge anything solely by its looks, right?

The inverted pyramid shaped house one of 12 such projects by French Developer Christian Bourdais who aims at capturing where the cutting edge of architecture stands at the beginning of the 21st century. The gravity defying structure stands out starkly against the otherwise downward sloping mountainous landscape of Matarrana, creating a beautiful contrast. On the inside, the slopes of the pyramid become the staircases that guide one around the eccentric establishment, leading to mezzanine floors and rooms that offer a spectacular view of the mountains outside. Plus, would you look at that inverted pyramid pool!
