The first floor was destroyed and most of the ground floor was damaged by the fire. There are no reports of any injuries.
Control Officers took the first of three calls at 1956 and mobilised crews from Edmonton and Tottenham fire stations to the scene. The fire was extinguished by 2113.
The cause of the fire is under investigation.
