Fire Triangle

California's first 3D printed fire-resistant ADU shows how a single non-combustible backyard build can act as a neighborhood firebreak — not just a guesthouse.

How Builtech's Walnut ADU applies the fire triangle to wildfire defense — engineering 'fuel' out of a 3D-printed concrete home for non-combustible resilience.

Wildfire-resistant home design depends less on walls than on roof, eaves, and windows. Inside the 3D-printed Walnut, CA ADU rewriting fire-survival rules.

How Builtech's Walnut, CA project mapped the permit pathway for fire-resistant 3D-printed concrete ADUs.

A steel and Sure-Board roof gives a 3D-printed ADU a Class A, no-wood, no-nail envelope engineered to deny wildfire fuel and survive ember storms.

Compact modular robotic 3D printers let contractors print concrete ADUs in tight residential backyards. Here's why the form factor changes the game.

Most 3D-printed fire-resistant homes still ship with wood-truss roofs, leaving them vulnerable to embers. Here's why a steel-roof envelope is the missing layer.

Concrete walls don't make a 3D-printed ADU fireproof. See why eave vents and windows decide whether a printed home survives a California wildfire.
