Part of the first and second floor of a detached three-storey building were damaged by fire. A small part of the roof was also damaged.
The Brigade was called at 4.27pm and the fire was under control by just before 7pm. Fire crews from Addington, Croydon, Biggin Hill, Purley and surrounding fire stations were at the scene.
The cause of the fire is under investigation.
