Six fire engines and around 35 firefighters were called to a house fire on Arden Road in Finchley, N3 this morning.
The roof and first floor of the semi detached property, which was under refurbishment, was badly damaged by the fire as well as part of the roof of the neighbouring house.
Twelve people left the house which was being renovated before the Brigade arrived and thankfully there were no injuries.
The Brigade was called at 0942 and the fire was under control by 1131. Crews from Finchley, Hendon, Hornsey and West Hampstead fire stations are attending the incident and will remain at the scene damping down. Two aerial ladder platforms were also in use at the scene.
The cause of the fire is under investigation.
