Volcano House

Perched atop a 150-foot cinder hill like a UFO come to rest, the Volcano House is a highly unique mid-century gem. Its round, open floor plan affords 360-degree views of the surrounding mountains, with sliding glass doors giving access to the wrap-around deck. Inside, you'll find two bedrooms, two bathrooms, tile floors, tall, curved ceilings, and impressive stonework, while outside there's a separate garage/apartment at the bottom of the hill, an on-site lake, and 60 acres of Mojave Desert to explore.
