This LEED Platinum estate uses the colder temperatures found underground to subsidize the cooling needs, and has the ability to capture rainwater on nearly one acre of roof and hardscapes. Made of locally sourced materials to reduce its carbon footprint, as well as a grey and black water system for irrigation. Expansive decks, bespoke pool and spa, and natural landscaping help dissolve the boundary between exterior and interior living and create quintessential California living.
