The Polyhaus Tetra-One is a compact accessory dwelling unit that advances wildfire protection while rethinking affordable housing. Instead of relying on conventional timber framing, its structure uses cross-laminated panels sourced from forest restoration projects, wrapped in insulated metal layers that create a sealed, highly fire-resistant envelope. Robotic fabrication eliminates air gaps, further boosting durability and energy efficiency.
At 540 square feet with a 100-square-foot mezzanine loft, the home fits a kitchen, bathroom, living area, and sleeping space into a small footprint. Prefabricated components allow the entire unit to be assembled in just three days, offering a rapid solution to urgent housing needs. By tying its material sourcing to forest management, Polyhaus links construction directly to wildfire prevention. Positioned at around $300,000, the Tetra-One highlights how resilience, speed, and sustainability can intersect in California’s housing future.
