Crews worked to put out a three-alarm fire that heavily damaged four buildings in Seattle’s north Beacon Hill neighborhood early Thursday.

Seattle fire said the fire alarm center received a call about a fire at a new construction site at 5:42 a.m.

The buildings are in the 1000 block of Sturgus Avenue South, which is near the I-90/I-5 interchange. The fire started in a building under construction and then spread to adjacent buildings.

At the height of the fire, the response went to three alarms to summon additional resources. Fourteen fire engines and four ladder trucks were used to fight the fire.

More than half of the city’s firefighters responded to keep the fire from spreading further.
