Families affected by the fire on the 27th floor of the famous Trellick Tower were left ‘frightened and shaken’.
Two hundred people were evacuated for the Grade II listed building in Kensal Town, North Kensington after fire took hold of a flat on Wednesday (April 19) evening.
Two properties are believed to have been damaged by the flames, thought to have started on a balcony.
Among those at the scene was local Labour councillor Emma Dent Coad, who sits on the Golborne ward.
She rushed to the Golborne Road building, designed by architect Ernő Goldfinger, after hearing of the blaze while attending a meeting.
She said: "When we got there fire fighters were dealing with the families.
“We were told that fire was bursting out of the window which was quite frightening.
“The families were in shock but they were OK. No one was hurt, but they were frightened.”
London Fire Brigade (LFB) has launched an investigation but says a carelessly discarded cigarette is thought to have caused the fire.
The councillor added: “It could have been a hell of a lot worse,” and writing on Facebook, added: “Disaster averted.”
LFB said a woman and two children managed to escape the flat before fire crew arrived.
Eight fire engines and 58 firefighters were at the scene, with the 999 control room receiving more than 40 calls from concerned members of the public.
The fire brigade was called at 9.23pm and had the flames under control by 10.51pm.
