Multiple units responded to a house fire in the Newport Shores community of Bellevue that caused major damage, but no injuries Thursday night.

Bellevue firefighters responded to the two-story house around 7 p.m. Thursday where a one-story addition had caught fire, later spreading into the kitchen, adding luckily no one was home at the time. Firefighters focused suppression on the right, back and front side of the house with Mercer Island, Kirkland and Eastside departments assisting.

“A lot of companies went to the roof and opened up the roof on the second story,” said Burke. “(The fire) was mostly contained to that new addition off the back, but it did get into the kitchen area, which caused a lot of damage to the house.”

Supplementary crews provided protection to adjacent homes, which were undamaged by the fire.

A second fire investigator was brought in to expedite the investigation as snowfall Thursday and Friday was expected to interfere, and a cause for the fire is still being determined. Damage to the structure is estimated at more than $300,000.
