Crews spent over an hour putting out a fire at an empty house in Lowergate just before 5pm yesterday (Thursday).
Four fire engines from Clitheroe, Hyndburn and Blackburn located a fire on the first floor of the building, which is currently under renovation.
A spokesman for Lancashire Fire and Rescue said: "The fire was confined to one room within the premises and also involved a window frame.
"Firefighters extinguished the fire using two breathing apparatus, two hose reels and a ventilation unit. Firefighters were in attendance approximately one hour and twenty minutes."
