Fire at a home on Abbott Street in Kelowna Wednesday

An older home with sawdust insulation made extra work for Kelowna firefighters late Wednesday night.

Fire officials say the blaze broke out just before midnight at a home in the 1800 block of Abbott Street.

Crews arrived to find smoke pouring out the back of the home with fire on the back deck and some of the roof.

Damage to the home is extensive.

No one home at the time and an investigation is underway to determine the cause.
