A busy night for Oklahoma City firefighters as flames engulfed a house on the northwest side of the metro.

It happened near NW 33rd Street and Classen Avenue at what officials are saying was a garage that had been turned into a couple of apartments.

No one was there at the time of the fire that preliminary reports indicate destroyed the house.

The cause of the fire is still undetermined at this hour, but officials believe that it apparently started in the back of the building.
