The London Fire Brigade said the whole of the three storey building at Campden Grove, W8 is alight and part of the roof of a neighbouring property was on fire.
Station Manager Rhodri Horton, who is at the scene said: “When crews arrived they were faced with a rapidly developing fire affecting the whole of a three storey house under refurbishment. Firefighters are working hard to bring the fire under control.
“A mother and a daughter from a neighbouring property escaped into their garden. Fire crews used a ladder to get them over a fence and away to safety. Thankfully they were both uninjured.”
The brigade said the fire was brought under control after four hours at 10.30am.
