A young family is homeless after their northeast Calgary home went up in flames on Thursday evening.

By the time crews arrived on scene, flames and smoke were pouring out of the home.

The family was not home at the time and a neighbour called 911 when he smelled smoke.

"We just smelled plastic first. We were running around the house here because we didn't know what was up cause I thought it was our house," said neighbour, Dennis Omeaso.

The second level of the Taravista St. house was heavily damaged and the rest of the home had smoke throughout.

Crews say the fire at the home was intense. "The fire was deep seated in the building. We had to do a lot of overhaul and pull down a lot of ceilings and walls to finally extinguish the fire,"

Investigators say the fire was likely caused by an electrical appliance.

Damages are pegged at about $150,000.
