FAQ
PHNX Development is a design-build firm focused on high-performance custom homes. We are a California C-Corp, incorporated in 2021. We are a fully insured and bonded licensed California General Contractor #1098724. Our founder & CEO, Laurie Fisher, is also a CA Registered Architect and Legacy LEED Accredited Professional.
We integrate architecture, engineering coordination, budgeting, and construction under one disciplined process. Our goal is to deliver homes that are structurally resilient, energy efficient, and thoughtfully designed — without the fragmentation typical of traditional design/bid/build projects.
PHNX is a design-build firm specializing in noncombustible Type I residential construction.
We design and construct custom homes using advanced structural systems, including our patent-pending Longspanâ„¢ system, eliminating the need for wood sheathing and engineered to deliver extended structural spans, fire resistance, and long-term durability.
Unlike conventional wood-framed homes, PHNX homes are built with noncombustible, wood-free structural assemblies designed for resilience and performance. We are currently the only residential design-builder in the nation delivering this level of Type I construction in custom single-family homes.
Beyond the structural system, PHNX integrates award-winning architecture, engineering coordination, budgeting, and construction under one accountable team. Structural performance, cost alignment, and constructability are addressed from the beginning — not after drawings are complete.
The result is a home built for strength, efficiency, and longevity — delivered through a controlled, unified process.
We specialize in custom single-family homes and select multi-structure residential projects, including ADUs and detached elements when appropriate.
Our streamlined, trauma-informed process is tailored specifically to the needs of fire survivors. However, our non-survivor clients have found our process easier to navigate and far superior to other design/build professional services.
Our work emphasizes durability, performance, and long-term value over short-term trends.
