Three fire engines and around 15 firefighters were called to a fire at a maisonette on Taylor Close in Hampton Hill.
Half of the ground floor of a split-level maisonette was damaged by fire. Firefighters led one man to safety from the roof of the building via an extension ladder. He was treated on scene by London Ambulance Service crews after suffering from smoke inhalation.
The Brigade was called at 1751 and the fire was under control by 1837. Fire crews from Twickenham and Feltham fire stations attended the scene.
The cause of the fire is under investigation by the Brigade and the Metropolitan Police Service.
