A Department of Fire and Emergency Services spokeswoman said 16 firefighters from Duncraig, Osborne Park, Malaga and Wangara attended the fire at the store, which is near Kingsway Shopping Centre.
The fire was reported at 12.34pm and was under control by 12.44pm.
Bystander Tim Barton, a shop-fitter from Padbury, said the building looked ‘pretty good’ after the blaze considering how much thick smoke had reduced visibility across Wanneroo Road.
‘It looked really bad,’ he said.
‘There was a lot of black smoke and basically you could see the flames coming out through the roof.’
