A large fire caused “heavy” damage to a million-dollar Suwanee home that’s been for sale for more than a year, Gwinnett County Fire and Emergency Services said.

Firefighters were dispatched to the home in the 4900 block of Brendlynn Drive in Suwanee at 9:53 a.m. Tuesday. There was “heavy fire involvement” when crews arrived to the large Tudor-style home.

The fire started in the basement and rose through upper floors, eventually reaching the attic. The owner told firefighters that a real estate agent reported an issue with the electrical breaker box the day before the fire. The cause has not yet been determined, according to a department spokesman.

The house, which is in a gated community, was vacant when it caught fire, said Capt. Tommy Rutledge, a spokesman for Gwinnett County Fire and Emergency Services. The 8,600-square-foot custom-built home is currently for sale for nearly $1.1 million, according to Zillow.

Firefighters were able to extinguish the fire by 1:02 p.m. Two firefighters were evaluated at the scene for heat-related conditions, but did not need to g to the hospital.

The home is part of the Bear’s Best Estates subdivision, located near the golf course and the Chattahoochee River.
