Barcelona-based studio Cadaval & Solà-Morales has designed the House in the Pyrenees project. Completed in 2010, this two story contemporary home is located in Canejan, a small village in the Val d’Aran, a valley in Catalonia, Spain. The vernacular dry stone house is a comfortable residence that have two units on a single envelope. It features amazing views over the valley, while an identical window located on the top of the roof, enables to view the summit of the mountain.  By preserving the envelope and doing a minimal yet contrasted intervention, the idea is to reinforce the historical values of vernacular architecture. Moreover, the project is design to be sustainable. New technologies and old vernacular knowledge are implemented to make the Pyrenees houses two sustainable houses in an extreme climate.
