A holiday home located in the north part of Nahuel Huapi Lake, in the Lake District of Argentinian Patagonia, Casa Techos is set between the trees on the lower level of the site. The public and family spaces occupy the ground level, and guest rooms and service areas are on the lower level. Challenges included meeting local standards requiring that the roof have a minimum slope, and providing for the client's request for ample natural lighting. The use of terraces and patios increases the perimeter and, along with the skylights, they generate a interplay between interior and exterior spaces.
