Eight fire engines and around 60 firefighters tackled a fire on Cottrill Gardens in Hackney.
At the height of the fire, a static caravan and two cars were alight, as well as part of a grass embankment. There are currently no reports of any injuries.
Control Officers took the first of over 20 calls at 1810 and mobilised crews from Homerton, Leyton, Whitechapel and surrounding fire stations to the scene. The fire was under control by 2042.
The cause of the fire is under investigation.
