The fire was located in a mid-terraced house of two floors. Part of the ground floor was damaged during the incident, and an external pergola was destroyed by the fire. There are no reports of any injuries.
The Brigade received the first of 20 calls reporting the fire at 2103, and Control Officers mobilised crews from Plumstead, Eltham and East Greenwich fire stations to the scene. Firefighters had the incident under control by 2208.
The fire is believed to have been accidental, caused by the unsafe disposal of smoking materials.
