Eight fire engines are currently at the scene of the blaze on Star Street, just off Edgware Road.
London Fire Brigade are in attendance alongside the London Ambulance Service.
The incident has partially blocked the A5 Edgware Road, causing tailbacks to Marble Arch.

The cause of the fire is currently unknown.
A spokesperson for the fire service said: "The Brigade was called at 1719. Fire crews from Paddington, Euston, Kensington, North Kensington and surrounding fire stations are at the scene."
