Tetra-Three (1,165 SF):

28’x28’ (Footprint)

At the scale of a detached town-home, the Tetra-Three includes the following spaces: x2 Bedroom, x3 Baths, and a Sleeping Loft, distributed across a 510 SF Ground Floor, a 510 SF First Floor, and a 145 SF Sleeping Loft.

Sustainable, Climate-Change and Wild-Fire Resilient: Polyhaus models uses sustainable, highly resistant materials and advanced manufacturing techniques to achieve climate resiliency. The use of digitally fabricated Cross-Laminated-Timber (CLT) panels reduces the carbon footprint and respects ecosystems while maximizing structural efficiency and wildfire resiliency.

Made entirely out of Cross-Laminated-Timber (CLT) panels, we are thrilled about Polyhaus’s environmental sustainability. With Douglas Fir, sourced from restoration projects in the Colville National Forest, led by our partners Vaagen Timbers in WA, we are proud to offer a housing solution that builds a direct link between the health of our National Forests and our housing production in California.

In addition, the Cross-Laminated-Timber (CLT) panels offer a high degree of wildfire-resilience given that they are robotically fabricated and leave no airgaps that would otherwise feed the fire, as it happens in conventional study construction. According to the National Design Specification (NDS) for Wood Construction, and the Non-profit WoodWorks.org, the nominal char rate for CLT panels is 1.5 inches per hour. With CLT panel thicknesses ranging between 4.5 - 7.5 inches, this wall assembly effectively increases fire-resiliency three to five times that of conventional wood construction. The Cross-Laminated-Timber (CLT) panels are in turn wrapped by high-performing Insulated Metal Panels that offer their own unique fire resistance. Finally, the aerodynamic form that results from the model’s uniquely patented shape also minimizes areas vulnerable to wildfire propagation. Polyhaus’ unique wildfire resilience has garnered national and international attention!
