Six fire engines and around 40 firefighters were called to a fire at a restaurant with flats above on Kilburn High Road in Kilburn.
Half of the external extraction system at the rear of the property from the ground floor to the roof was damaged by fire. Half of a void between the ground and the first floors of the building was also damaged by the blaze. There were no reports of any injuries.
Station Commander Ned Alexander, who was at the scene, said: “The fire was located inside a void between the ground and the first floor of the building and crews used cutting equipment to gain access and bring the fire under control.
“Kilburn High Road is closed between Gascony Avenue and Kingsgate Place, so we advise people to avoid the area. Crews are expected to remain on scene damping down for a number of hours.”
The Brigade was called at 5.56pm and the fire was under control by 8.05pm Fire crews from North Kensington, Paddington, West Hampstead and Kentish Town fire stations attended the scene.
The cause of the fire is under investigation.
