Six fire engines and around 40 firefighters tackled a flat fire on Aberfeldy Square in Poplar.
Part of a flat on the eighth floor of the building was damaged by fire and the balcony and window were destroyed. One person left the property before the Brigade arrived and was assessed on scene for injuries.
Station Commander Paul Sadler, who was at the scene, said: “Crews worked quickly to bring the fire under control.
“The Brigade’s drone, equipped with a thermal imaging camera, was deployed to identify remaining hot spots, allowing crews to fully damp them down.”
The Brigade’s Control Officers took the first of 30 calls to the fire at 1606 and sent crews from Poplar, Plaistow, Millwall, Stratford, Shadwell and surrounding fire stations to the scene. The fire was under control by 1707.
The cause of the fire is under investigation.
