Houses With Distinctive Roofs

Enric Luiz-Geli's Villa Bio project in Llers, Spain is not only environmentally friendly but of the environment. "We're interested in the performative dimension of nature—how it grows, lives, and transforms," notes the architect. "We strive to cultivate this organic dimension." From its hydroponic rooftop garden to its unfurling interior, the structure echoes the sloping hillside forest that sits just beyond the property line. The garden is also one of the home's primary sustainable features, soaking up excess runoff and providing protection from dangerous winds.
