About 125 firefighters are tackling a major blaze at a block of flats in south-west London.
The fire quickly spread to all four floors of the building in Sherbrooke Way, Worcester Park, after fire crews were called just before 01:30 BST.
Some 20 fire engines were at the scene, the London Fire Brigade (LFB) said. The cause of the fire is not yet known and no injuries have been reported.
The fire was under control at 06:30 but crews will remain there during the day.
Dean Fowler, who lives with his family on the top floor of the building, said he was woken in the night by someone banging on his door.
“I then heard someone screaming ‘there’s a fire, get out’, and I just got my boys and went,” he said.
He said he had only been living in the building for three weeks and had lost “everything” in the blaze, but added: “we’re alive, we’re breathing, that’s all that matters”.
The building is made up of 23 flats and based in The Hamptons estate, an American-style complex made up of social and private housing which was built on a former sewage treatment works.
Residents from the block and surrounding buildings have been taken to a nearby community centre.
One of those, Darren Nicholson, said he woke up to the sound of “crackling” and when he opened the curtains he “saw the flames and got myself and the family out”.
He said fire alarms were going off in the community areas but not in his own flat and he believed the blaze began “on the balconies”.

What was once a four-storey building is now just a shell.
You can hear the block falling apart and black and white smoke continues to billow from it.
The closest building, which has also been evacuated, is quite far away so it is not possible that the fire could spread.
However, the thick smoke is going into these houses and covering the entire block.
Residents from other parts of the estate have been bringing bags of clothing and bedding to the community centre to donate to those people who have lost everything.
Graham Adams, from London Fire Brigade, said: “This is a challenging fire and firefighters are working hard to bring the blaze under control.
“Firefighters will remain on scene for a number of hours and we would urge people to avoid the area if possible.”
London Ambulance Service said: “We have not treated any patients, however we remain on the scene as a precaution.”
Sutton Council said it had officers on the site who were “supporting anybody that needs help”.
