Modular fire station allows for possible future reconfigurations

In Southern California’s Rancho Mission Viejo (RMV), Fire Station 67 has been designed and constructed as a prefab, modular build—enabling faster completion and future reconfiguration.

Designed by Seattle-based Wittman Estes, the 4,667-sf station was prefabricated offsite as 10 modules that were then assembled onsite. The offsite fabrication and rapid assembly led to a streamlined design, documentation, and permitting process. This approach allowed for parallel site development work in California and factory construction in Nevada, resulting in a construction timeline of six months. 

Fire Station 67: Modular System

The modular system also allows for relocation and reconfiguration. The sturdy, durable steel modules can be easily transported and rearranged for possible future uses, such as an environmental learning center for RMV.

Fire Station 67 includes a vehicle bay for two fire trucks, six sleeping rooms, a day room, kitchen/dining room, dispatch/workspace, and a captain’s office. The 12-foot modules were assembled around a shaded, semi-protected central courtyard.

Construction Strategy

The building configuration enables the firefighters to serve the public quickly while also feeling calm and privacy. The north-facing public entry, captain’s office, and dispatch room face the neighborhood. The more active areas, including break room, kitchen, and fitness rooms, face east toward the firetrucks. And the sleeping rooms and bathrooms are located in a quiet zone in the west. The firetruck bay is painted bright red, while the interior spaces have a neutral, tranquil palette.

In response to climate change and the rising risk of wildfires, the prefab structure is clad in fireproof, corrugated steel siding. To improve indoor air quality, Wittman Estes designed an open-air apparatus bay to bring in fresh outside air and eliminate the need for large exhaust machines.
