Four fire engines and around 25 firefighters tackled a fire at a mid terraced house on Wightman Road in Hornsey.
Half of a three roomed flat on the ground floor was damaged by the fire. Two people left the building before the Brigade arrived. There are no reports of any injuries.
Control Officers took the first of eight calls at 2000 and mobilised crews from Holloway, Tottenham and Stoke Newington fire stations to the scene. The fire was extinguished by 2058.
The cause of the fire is under investigation.
