A blaze which gutted an unoccupied Carterton house early yesterday is being treated as suspicious.
Four fire appliances from Carterton, Greytown and Masterton rushed to Rexwood St at 3am and firefighters found the house engulfed in flame.
Initial fears for two missing occupants were allayed when it was determined no one was home at the time.
A breathing apparatus tender from Avalon was called in to provide support for the firefighters' oxygen equipment.
The 1920s bungalow was on the market priced at $240,000.
