Four fire engines and around 25 firefighters tackled a fire at an end of terrace house on Imperial Road in Fulham.
Most of the ground floor and part of the first 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 25 calls at 0854 and mobilised crews to the scene from Wandsworth, Battersea, Kensington and surrounding fire stations to the scene. The fire was extinguished by 0948.
The fire is believed to have been accidental and was caused by combustible items left too close to a heat source.
