Firefighters helped a man to safety this afternoon after an apartment block in Primrose Hill caught fire.
Two flats - on the first and second floors of the block - have been damaged.
The building, on the corner of St Edmund's Terrace and metres from Primrose Hill park has been undergoing refurbishment.
The fire brigade was called to the scene at 12.34, and there were 40 firefighters tackling the blaze - including crews from Euston, Kentish Town, Paddington and West Hampstead.
Firefighters led one man to safety using a gas-proof hood, while a man and a woman were treated at the scene by the London Ambulance Service.
Station Manager Ben King, at the scene, said: "When crews arrived they were confronted with a well-developed fire and worked quickly to bring it under control.
"The fire was very visible and our control room took a high number of calls to the incident."
The cause of the fire is unknown at this stage.
