This Southern California home, based in the Santa Monica Mountains and is practically indestructible, is on the market for $4.5 million.

Dubbed the Stunt Road Compound, it’s made of steel-reinforced concrete and is carved into the Santa Monica Mountains’ Saddle Peak, some of which is actually partially buried.

The roof is covered with plants in soil nearly three feet deep, and has foot-thick concrete walls, which are the same color as the ancient boulders that surround the home, allowed it to blend into the landscape. In the middle of the home is a “light well” with a koi pond in the middle. There’s also a master suite that has two full-size bathrooms and closets, which the property website calls it the home’s “command center”.

There’s two homes on the 44 acre property — a 3,900-square-foot house hidden in a ridge outside Calabasas, and another 2,500-square-foot midcentury-inspired house built in 1996. For more info, visit the property’s website.
