Five crews were called to the scene at Tegula Street in Mansfield just after 2.30am on Friday.

A Queensland Fire and Emergency Services spokeswoman said when they arrived, the home was engulfed in flames.

She said the occupants had escaped and were all accounted for.

It took about 80 minutes for the fire to be brought under control.

Fire investigators are expected to re-visit the site Friday or Saturday to try to determine the cause of the blaze.
