UPDATE: A fire which destroyed a Doonan home is believed to have started in the same area where a pot belly stove as well as a fridge and freezer were kept.
Queensland Fire and Emergency Services fire investigator Geoff Hunter has spent this morning examining the scene at a Noosa Eumundi Rd property.
Mr Hunter said investigations were ongoing, but said it appeared the blaze had started in a centre shed area of the home.
He said it was too early to tell what exactly had sparked the fire.
EARLIER: A woman has escaped uninjured after being woken by the noise of her Doonan home being destroyed by fire.
Queensland Fire and Emergency Services officer Acting Inspector Archie Andrews said the woman was sleeping in the front section of her Noosa-Eumundi Rd home when fire broke out at the rear of the property about 1.40pm yesterday.
"She heard crackling and banging noises from the actual fire itself," Act Insp Andrews said.
"They didn't have a working smoke alarm."
The woman was able to flee the blaze without being harmed.
There were more than 30 firefighters working on the blaze at its peak, with the rural teams supplying water to the urban teams.
It took them about 20 minutes to bring it under control, with the fire extinguished within about two hours of arrival.
Act Insp Andrews said there had been initial concerns that up to four other people, including the homeowner, could have been inside the inferno but they were soon confirmed to have been away from the property at the time.
Act Insp Andrews said the woman was lucky to have escaped.
"Had she not woken up it might have been a different story," he said.
He implored home owners to install smoke alarms.
"Anywhere between $10 and $30 will give you a very good, working smoke alarm."
He also noted that with recent cold weather, residents needed to be vigilant with any pieces of heating equipment.
The destroyed home was not insured.
Fire investigators will work to confirm the cause.
