Police and fire crews were called to the home on the intersection of Crown and Premier St at 2.10am after receiving a call from neighbours.
It took two fire engines to extinguish the blaze and investigators have been called in to determine the cause of the fire, which is being treated at suspicious.
"The house has been extensively damaged, with three quarters of the building completely gutted," Sergeant Bruce Hodgins said.
