It took firefighters three hours to extinguish a stubborn fire Thursday evening at an under-construction home in Lake Forest, officials said.

The Lake Forest Fire Department responded around 6:26 p.m. Thursday to the 1500 block of Kathryn Lane for a report of a structure fire.

Several neighbors spotted flames coming from the large unoccupied home and called 911, Lake Forest Fire Department Division Chief Michael Gallo said.

Firefighters arrived to find flames and smoke showing and initiated an interior attack on the blaze.

The response was upgraded through the Mutual Aid Box Alarm System (MABAS) in order to bring more personnel to the scene.

The house was under construction at the time and no one was living there, Gallo said.

The fire was declared under control at 9:25 p.m., nearly three hours after the first 911 call. Firefighters performed overhaul to ensure complete extinguishment, Gallo added.

There were no reported injuries to civilians or firefighters during the incident. The cause of the fire is under investigation and a damage estimate was not immediately available.
