The blaze was extinguished shortly before 12pm, however the roof of the building has completely collapsed.

“Crews are still at the scene mopping up little pockets of fire,” a QFES media spokeswoman said.

“We have a fire investigator there now and they are trying to work out exactly what caused it.”

Beaudeane Bird, the granddaughter of business owner Jana Whittaker, said her “heart breaks for my Nan today.”

“She has put her heart and soul into this business and to see it burn to the ground today would have been the most heartbreaking thing,” she said in a Facebook post.

“I’m so glad everyone is okay.”
