Police believe a car fire that destroyed a Padbury home at the weekend was lit deliberately.
The blaze was sparked about 9pm on Friday after a Ford Falcon sedan was set on fire in the carport of the Buchanan Way property.
The fire spread quickly to the house and gutted the property, causing $550,000 damage.
The owners were not at home at the time.
Arson squad detectives are investigating the cause of the fire, including whether vehicles found at the property had been stolen.
