Our first PHNX home in San Diego is going up!! 🙌

The only load bearing walls in a PHNX home are the exterior walls. They are Fox Blocks insulated concrete forms, filled with concrete and rebar, and the foam stays in place and insulates the wall to R-30.

Everything else inside is light gauge steel, and none of it is structural. If a wall doesn't need to be load bearing, then we don't make it a concrete wall.

The site stays clean and quiet the whole way through. So proud of this team.

With Fox Blocks, the California Nevada Cement Association and NRMCA.

Training day. Builders from across California are on site at a PHNX build in San Diego, learning ICF with the Fox Blocks team. Concrete and steel walls, Type IA noncombustible, and a growing network of crews who know how to build them.

Thank you to Fox Blocks and BARC Builder Group.

We made the cover. 🏠💚
The PHNX Yosemite Lake House is featured on the cover of the September/October issue of ICF Builder Magazine — an issue dedicated to ICF Resilience Proven.

This award-winning PHNX Home shows what’s possible when resilience, sustainability, design and affordability are treated as one idea — not tradeoffs.

Wood-free. Noncombustible. Net-zero. Built in less than a year. At the same cost as conventional wood construction.

Forever Homes for Everyone.

In the early 2000s, wildfires destroyed about 3% of the California homes they reached; by 2020, that number was 18%.

The original wildfire code did real work against the kinds of fires we had in the 90s. Where PHNX has been outspoken is what’s happened since: the way WUI code keeps evolving isn’t addressing the kinds of fires we have now, and in some cases may be making homes more vulnerable, not less. A new UC Merced study backs up exactly that concern; today’s fires are hotter, faster, and bigger than the ones the current code updates are still chasing.

The hardening numbers make the point sharper: 48% of hardened homes survived some of California’s largest fires, against 20% of unhardened ones. Real protection, when the code gets it right. The problem PHNX keeps raising is that its current direction isn’t built for the way fires burn in the 21st century.

That’s the gap the patent-pending PHNX Longspan™ Structural System was built to close. Wood-free, Type I noncombustible construction, built for the kinds of fires we have now instead of the ones code-minimum hardening keeps chasing after the fact.

Most homes look beautiful.
The biggest difference is what you can’t see.

What sets a PHNX home apart isn’t the finish. It’s the structure behind it.

At PHNX Development, we build the nation’s first wood-free, Type I noncombustible, net-zero homes designed to protect what matters most.

Why PHNX?
• Wood-free, Type I noncombustible construction
• Pre-qualified for insurance in high-risk fire areas
• Net-zero energy performance
• Award-winning architecture and design
• Built to last generations, not decades
• Cost-competitive with traditional wood construction

Resilience shouldn’t be a luxury. It should be the standard.

Whether you’re rebuilding after wildfire or planning your forever home, we’d love to help.

“Ignition-resistant” and “noncombustible” aren’t the same thing.

It’s a distinction many homeowners don’t realize until they start researching how to rebuild after a wildfire.

An ignition-resistant wall is still built with combustible wood framing. Building codes require the exterior assembly to resist ignition for a period of time, but the structure itself remains combustible.

A Type I noncombustible wall is different. Its primary structural elements are noncombustible, providing a completely different level of fire performance.
Neither approach is wrong. They simply offer different levels of resilience.

At PHNX, we believe homeowners deserve to understand the differences before making one of the biggest investments of their lives.

Education first. Decisions second.

What questions do you have about rebuilding with fire in mind? We’d love to answer them in the comments.
