Phnx Development

San Diego-based PHNX Development has pioneered the nation’s first fully non-combustible, wildfire-safe home: PHNX Home™. Founded by architect Laurie Fisher, PHNX combines innovation with a commitment to environmental responsibility to create homes that are fire- and disaster-resistant and eco-friendly. The patent-pending PHNX Longspan™ roof & floor framing system eliminates the need for structural wood, creating the first ever Type I-A home for the same cost as traditional construction. With a focus on safety, durability, affordability, and accessibility, PHNX Development is shaping the future of residential construction through development of custom single-family homes, duplex/triplex/quadplex/townhome multi-family, as well as franchise and master-planned community opportunities.
