Firefighters were called out after a roof caught light.
The blaze broke out at a building in Station Road, New Romney, last night.
Three fire engines attended at about 7.45pm and were at the scene for an hour.
Crews wearing breathing apparatus used a high-pressure hose reel jet to put out the flames.
A spokesperson for Kent Fire and Rescue Service said: “There were no reported injuries and the cause is unknown.”
