Polyhaus

Fire-resilient mass-timber prefab homes with patented geometric efficiency.

Polyhaus is a La Jolla, CA design and building technology company founded in 2021 by Daniel Lopez-Perez and Celine Vargas. Their patented building system uses robotically fabricated cross-laminated timber (CLT) wrapped in insulated metal panels to create fire-resilient, rapidly assembled prefab homes. The geometric efficiency of their truncated polyhedron forms maximizes living space within a minimal land footprint. Models range from 540 to 2,500 sq ft. Featured in Dwell in 2025 and covered by the LA Times and Architectural Record.

How to use this profile

This profile presents Polyhaus as a research starting point for modular, clt, fire-resilient buyers. It combines the provider's published location, build method, delivery framing, named-model records, and any cited independent tours in one place so that a buyer can see both the useful details and the questions that remain.

For this provider, begin by choosing the specific model or program that fits your intended use, then compare its written factory or plan scope against the site work and local services your project will need. Ask who owns responsibility for engineering, permits, foundation, transport, setting, utilities, final completion, warranty response, and support after handoff. A listing or state chip is never an address-specific commitment.

Keep the provider's written answer with the proposal. It makes it easier to compare Polyhaus with other builders on scope and responsibility rather than a headline number alone.
