There were no injuries.

Stio called the home a "total loss." The cause hasn't been determined.

Homeowner Laura Messina said she was in the kitchen when the fire started.

"I was just cooking and it all went so fast," she said as she watched fire trucks hose down the smoldering ruins. "I just took my kids and ran."
