Polyhaus
The Polyhaus Tetra-One is redefining what modern housing can be. This innovative ADU (Accessory Dwelling Unit) combines smart design with climate resilience. Spread across 440 sq. ft. on the ground floor and a 100 sq. ft. mezzanine loft, it features a living room, kitchen, bonus area, and cozy sleeping space, all within a compact, efficient footprint.
What sets Polyhaus apart is its commitment to sustainability and wildfire resilience. Built entirely from Cross-Laminated Timber (CLT) panels, sourced from restoration projects in Washington’s Colville National Forest, the Tetra-One creates a direct link between healthy forests and sustainable housing. These CLT panels are robotically fabricated, leaving no air gaps, making them three to five times more fire-resistant than conventional wood construction. Wrapped in insulated metal panels, the home offers another layer of protection while maintaining excellent energy performance.
Founded in 2021 by Daniel Lopez-Perez and Celine Vargas, Polyhaus was born out of frustration with traditional stick-built homes, slow, inefficient, and increasingly vulnerable to California wildfires. Their solution? Prefabricated structures that are not only beautiful but also smarter, stronger, and faster to build.
From its prototype in La Jolla to designs now scaling up to 2,500 sq. ft., Polyhaus has gained international recognition for pushing the boundaries of eco-friendly, disaster-ready housing. With climate challenges on the rise, the Polyhaus vision is simple yet bold: build homes that protect both people and the planet.
