the grass cave house, yokohama/Makiko Tsukada Architects
love the dark interior textures of the grass cave house…choosing to leave ‘what is’ as is…and then incorporating plenty of interior light…
The plant-covered extension has living walls on three sides that not only visually link with the green roof and surrounding landscape but contribute to the passive systems that keep the house cool in lieu of air conditioning. Solar panels supply the home’s power while the green roof provides a solid supply of vegetables, watered by captured rainwater and recycled grey water. A central sculptural staircase leads up to the green roof but also doubles as a chimney by drawing cool air down into the house.
