Around 30 firefighters were called to tackle a blaze which broke out at a house in Glenrothes on Thursday evening.
Six fire engines in all were in attendance at the incident in Durris Drive, where the alarm was raised following a report of a fire within a mid-terraced property.
One person was treated at the scene for smoke inhalation, but did not require hospital treatment.
A spokesperson for the Scottish Fire and Rescue Service said it was called at 9.42pm and brought the fire under control by midnight, although significant damage was caused to the building.
Two appliances from Glenrothes, two from Methil, one from Lochgelly and one from Kirkcaldy were all mobilised to the scene at the height of the fire.
An investigation into the exact cause is under way.
