A fire has destroyed a home and two cars in Adelaide's east overnight, causing approximately $600,000 damage.
The fire broke out at a split-level home on Penfold Rd in Stonyfell just before 1.45am today.
It took firefighters an hour to extinguish the blaze, which spread to the roof.
An elderly couple who were home at the time managed to escape as flames took hold of the property.
Neighbours were forced to evacuate, while the Metropolitan Fire Service urged other residents in the area to stay indoors and keep the windows shut as smoked drifted towards the city.
Police initially treated the blaze as suspicious, but Fire Cause Investigators have since ruled out foul play.
They confirmed the fire was accidentally started in the carport, but the exact cause has not yet been determined.
