Firefighters battled a blaze Wednesday afternoon that broke out in the office for Hart Modular Homes near the corner of Highway 97 North and Bellamy Road.
No injuries were reported while the fire produced a massive plume of thick black smoke and destroyed the structure before the flames were brought under control.
In all, 19 firefighters were called to the scene shortly before 2 p.m. and found the building "fully involved," Prince George Fire Rescue said.
Cause of the fire remains unknown.
