Eighty three people have refused to leave their homes on the Chalcots Estate in north London where hundreds of residents were evacuated on Friday night amid fire safety concerns.
Camden Council evacuated around 650 homes, displacing some 4,000 people, with less than an hour's notice, after a decision was made at 6.30pm that the tower blocks were no longer safe.
The residents were moved amid distressing scenes to temporary accommodation after firefighters said they could no longer guarantee the safety of the buildings, council leader Georgia Gould said.
The evacuation came as the government said on Saturday that 27 high-rise tower blocks in 15 council areas had failed cladding fire safety tests.
Gould told Sky News that 270 hotel rooms had been used along with 100 places in social housing within Camden. Neighbouring boroughs had also been asked for support.
The buildings have been found to be covered with the same type of cladding as used at Grenfell Tower, five miles to the south west, where at least 79 people died in the June 14 tragedy. The council raised concerns about the block on Thursday when Downing Street revealed that as many as 600 buildings in the UK are encased in cladding.
Of the decision to evacuate, which was also made over concerns over "gas pipe insulation" Gould said: "At the end of today, they (the fire service) told us they could not guarantee our residents' safety in those blocks and so I have made the really, really difficult decision to move the people living there into temporary accommodation while we do the urgent works to guarantee safety.
"I know it's difficult, but Grenfell changes everything and I just don't believe we can take any risk with our residents' safety and I have to put them first."
Camden Council initially said just 161 households in the Taplow building on the estate were being "temporarily decanted" to allow up to four weeks of work to the building.
But Gould confirmed the number had increased to include all the buildings, with a rest centre set up at Swiss Cottage Library.
There was confusion on the ground at the estate as people were told to leave as darkness began to fall, with some leaving with belongings in suitcases and carrier bags. Some residents were also pictured carrying their pets.
Some locals said they found out about the evacuation from watching breaking news on television.
The council had already announced it would immediately begin preparing to remove cladding from the five towers on the estate discovered in checks following the fire in north Kensington.
Refurbishment of the Chalcots estate was overseen by Rydon, the company involved in the refit of Grenfell Tower, according to the Rydon website.
The site said the Chalcots project was a £66 million refurbishment that lasted 191 weeks.
The work included external thermal rain screen cladding on five towers, new aluminium thermally broken windows on five towers and an overhaul of external roofs. It added that 711 flats were modernised with new wiring, heating, kitchens and bathrooms.
The evacuations came as four more victims of Grenfell Tower were formally identified, taking the known victims to nine.
Scotland Yard said on Friday that manslaughter charges are being considered by detectives investigating the blaze in the tower, which had failed fire safety tests.
Prime Minister Theresa May tweeted: "My thoughts are with residents being evacuated in Camden while their homes are made safe tonight.
"We will work with and support the emergency services and relevant authorities to safeguard the public.
"Have asked @sajidjavid to keep me regularly updated & ensure we are offering every support we can to residents & those working onsite."
Camden Council said officials were going door-to-door one at a time for safety reasons, starting at Taplow then working through Burnham, Bray, Blashford and Dorney.
A spokesman said residents would be allowed in at the weekend to collect more possessions "under escort from the London Fire Brigade" and recommended people pack enough belongings for a two to four-week stay.
The British Red Cross said it had staff helping residents at the rest centre.
A London Fire Brigade spokesman said: "London Fire Brigade has been working at the Chalcots Estate with Camden Council.
"Following extensive joint visits and inspections the brigade advised that there were a number of fire safety issues in the buildings and recommended that residents should not remain in the buildings until these issues are resolved.
"Camden Council have acted on this by evacuating and providing the residents with alternative accommodation so that remedial works can go ahead as quickly as possible.
"London Fire Brigade officers will continue to work with Camden to put in place measures to improve safety for residents in these buildings."
A spokesman for Camden Council said in a statement issued at 1.24am: "So far we have secured hundreds of hotel beds for Chalcots residents.
"We're encouraging all residents to stay with friends and family if they can, otherwise we'll provide accommodation.
"Swiss Cottage rest centre is nearing capacity so we've secured more space at the Camden Centre King's Cross.
"Specialist staff are on the ground to assist residents with care needs. Pets are also welcome at both rest centres and hotel accommodation."
