A fire early Monday at recently constructed townhouse on Saskatoon’s west side caused an estimated $200,000 in damage.

A passerby called in the alarm just before 5:30 a.m. after spotting the blaze at the site located near the intersection of Diefenbaker Drive and Centennial Drive.

Firefighters arrived to discover flames showing from the main floor and basement. Crews entered the building and attacked the fire on the main floor but were unable to access the basement stairs and had to shift the attack from the building’s interior to its exterior, Saskatoon Fire and Protective Services said in a news release.

Crews were later able to reach the fire with water lines through basement and upstairs windows, and they also cut a hole in the side of the building to access the basement.

The fire was brought under control in about 45 minutes.

Firefighters reported the building and suites were unoccupied at the time of the blaze. There were no reports of injuries.

A fire investigator was on the scene early Monday.
