Rapid Assembly:

Polyhaus’ speed-centered building system significantly reduces time, labor, and opportunity costs. The rapid assembly is achieved by robotically (CNC) milling the Mass-timber panels that and assembled on site in days.

For example: In the case of the Tetra-1, its 64 panels were CNC milled in 22 hours and assembled onsite by 3 framers in 2.5 days (22 minutes per panel).  The rest of the building trades have conventional construction timing.

“With the Polyhaus system we anticipate to reduce total construction time by 40%, compared to traditional methods.  That is huge and we feel bullish about getting to 50% time savings as we perfect the system. And more so, if we think about it this way: by saving half the time, we could build twice as many homes.”

Space Maximization:

Polyhaus’ patented design methodology leverages the geometric efficiency of  truncated polyhedrons, maximizing living space within a minimal land footprint. These designs also enhance orientation and use-flexibility due to their three-dimensional symmetry.

For example, the Tetra-1 is 540 sq. ft. (footprint 26’x26’ and height of ~18’) and offers full bathroom, double-heigh living room, full kitchen, queen-size sleeping loft, and bonus area (laundry, closet, office, etc.).

Resilience:

By using wood from reforestation efforts in the state of Washington, Polyhaus is proud to build a direct link between the production of homes and the health of our forests: “overgrowth that could burn to build homes that won’t”* [*- Lily Kim, SD Magazine]

Wildfires: 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 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.

Weather: The insulated metal panel and mass timber envelope of Polyhaus provides superior weather protection and a high R-value, making it an ideal solution across all climate zones.

Long-lasting & low-maintenance:  Built from solid wood, Polyhaus embraces the enduring strength and natural resilience of mass timber—delivering a long-lasting structure that requires low-maintenance while celebrating the beauty and integrity of sustainable architecture.

Structural Symmetry: Polyhaus offers a building design that uses a perfectly balanced, three-dimensional structure to evenly support weight and resist movement, making it strong, stable, and visually harmonious from every angle.
