An explosion and fire at a home under construction in Wonder Lake prompted the response of multiple fire departments Sunday evening.

The McHenry Township Fire Protection District responded around 10:30 p.m. Sunday to the 6400 block of Aspen Lane in Wonder Lake for a report of a structure fire.

McHenry Fire Battalion Chief Kevin Sears said crews arrived to find smoke coming from a one-story, single-family home.

The building appeared to be an unoccupied residence under construction near completion in a neighborhood off of Route 120 west of Martin Road.

Sears said there was heavy damage to the front overhead garage door and other exterior walls, including blown-out glass from all side and rear windows.

Crews began an offensive attack on the fire from the interior of the house and searched for any occupants inside. No civilians were found.

The crews then transitioned into a defensive attack from the exterior until the integrity of the walls could be confirmed, Sears said.

The fire was controlled within 20 minutes and crews cleared from the scene in just over 60 minutes.
