Altadena, CA
A main residence and ADU, rebuilding after the Eaton Fire.
The Altadena Residence pairs a 2,522 sq ft main residence with a matching 516 sq ft ADU, using the 4C SAFE™ system for an Eaton Fire rebuild. Images shown are architectural renderings.
Every 4C SAFE™ rebuild is steel-framed, fire-resistant, and rated 1-HR and 2-HR fire-resistive, WUI compliant, and code listed (patent pending).
One rebuild, two structures, one panel system.
The main residence and ADU share the same 4C SAFE™ system, so both structures carry the same fire-resistant, factory-built construction and move through permitting and installation together.
One coordinated rebuild
The main residence and ADU are designed, permitted, and built as a single scope, so the property doesn't need a second disruptive construction phase later.
Fire-resistant from the frame out
Steel framing rated 1-HR and 2-HR fire-resistive gives this rebuild a fundamentally different fire-risk profile than the home it replaces.
