The cause of a fire that gutted a Safety Bay home is yet to be determined.
Emergency services were called to the Gumnut Crescent property just after 10.30am on Thursday.
It took them hours to bring the blaze under control.
A man and three children who were in the house at the time were taken to Rockingham Hospital with suspected smoke inhalation.
Luckily, no one was seriously injured.
A Department of Fire and Emergency Services spokesperson said no cause has been determined.
