Los Altos Hills

Geodesic Dome Home Defense

A one of a kind dome home on a dry Los Altos Hills hillside. Now its roof, eaves and walls get wet when fire heads its way, even after the family evacuates.

What We Found

This Los Altos Hills estate home is a geodesic dome with a detached garage, on a dry hillside that looks out over Silicon Valley. Open lattice under the house let embers blow straight into the space below the floor. The vents had no ember protection, dry grass ran up to the walls, and the roof was aging. The good news: the owner already had backup water, backup power and satellite internet in place.

What FireRoofs Did

We started with the basics. On our advice, the owner put on a new Class A roof with new gutters and had the trees trimmed back. Then we installed 4 roof sprinklers and 22 eave and wall sprinklers across the dome and the detached garage, on copper lines split into 3 zones. They wet the roof, the walls, the first 5 feet around the home and the spots where the deck meets the house. A smart control panel and our wildfire detection camera and sensor run the system. To keep embers out, we closed off the space under the home with metal gates and ember-resistant mesh, added mesh under the deck, and upgraded the vents to ember-resistant vents.

The Result

The home now has two layers working together: sprinklers that keep the outside wet, and hardening that keeps embers from getting in. The work was finished in October 2026. No system can promise a home survives a wildfire, but each layer here makes it harder for one to catch.
