A Gonville resident is the "luckiest man alive" after he escaped through his bedroom window as his house burned around him.
The fire is one of two in Gonville this week which are now under investigation.
Fire and Emergency NZ was alerted to a blaze at an Akatea St property about 3.30am on Monday.
Two appliances attended the fire which was well involved when firefighters arrived with the fire causing extensive damage to the house.
Whanganui senior station officer Craig Gardiner said the sole occupant got out of the house through the window of his bedroom where he had been asleep.
