QFES Acting Inspector Bruce Groer said the small timber home had been completely destroyed.
"The occupant wasn't home at the time, all persons have been accounted for- no one's been hurt or is missing," he said.
The fire was spotted by a passer-by who called Triple Zero, but it was too late to save the house.
"We'll have an investigation at the scene here and we'll gather some information from passer-by's and also the owner to see what's happened," Mr Groer said.
THE roof of a house has collapsed after the Tablelands property was engulfed in flames this morning.
A Queensland Fire and Emergency Service spokeswoman said eight crews were attending the fire, at a suburb near Murgon.
"No person was home but it looks like the house is totally destroyed," she said.
"The roof has collapsed.
"They (fire crews) are still there, they are getting water supplies and trying to put the fire out."
The fire was reported at about 11.20am.
