This from Daniel Hynd:
The Darien-Woodridge FPD responded to a house fire in the 7900 Blk of Fairmount Ave in unincorporated Downers Grove last night. Crews arrived on scene with heavy fire through the roof of a 1-story, single family ranch reported to be under construction. Companies were defensive for most of the operation and fire was under control around 30 minutes after arrival.
