The Calgary Fire Department (CFD) said a home in the northwest community of Sandstone Valley suffered “extensive” damage on Tuesday following a fire.
A neighbour called 911 to report the blaze at around 5:30 a.m.
Firefighters arrived at the 300 block of Sandstone Drive N.W. to find thick smoke pouring from the rear of the single-storey home and flames eating away at the structure.
No one was at home at the time as the house was under rennovation.
The CFD said two neighbouring homes suffered damage to their siding. The homes were evacuated while crews fought the fire, but residents were allowed back in once the fire was extinguished.
Investigators are looking into what caused the fire.
No injuries were reported.
The CFD is asking anybody with photos, video or information about the fire to email piofire@calgary.ca.
