Albert Frey designed Frey House II as his own home and completed it in 1964. He placed the house on a rocky hillside above Palm Springs, building around a large boulder rather than removing it. Inside, that rock separates the living and sleeping areas. The compact house uses steel framing, large glass walls and a corrugated metal roof. Frey lived there until his death in 1998, when he left it to the Palm Springs Art Museum. The museum’s ownership preserved the architect’s home along with its unusually direct relationship to the hillside. Source: https://en.wikipedia.org/wiki/Frey_House_II
