Camden Council leader Georgia Gould said she "could not ask residents to stay in here for an extra night" due to safety concerns over gas insulation and cladding at the Chalcots Estate flats.
EARLIER: Some 34 high-rise buildings in 17 local authorities across the country have failed fire cladding safety tests after the Grenfell Tower disaster, the Government has said.
British officials have conducted tests on some 600 high-rise buildings across England after fire ravaged the Grenfell social tower block in west London on June 14, in the capital's most deadly blaze since World War Two.
Ms Gould said the council chose to evacuate the buildings on the Chalcots Estate late on Friday after fire inspectors told officials the blocks were unsafe.

Javid said the decision to evacuate four towers on London's Chalcots Estate was taken because a failed cladding test had been "compounded by multiple other fire safety failures". They say about a dozen families still remaining in their apartments must leave.
Some 83 households have refused to leave their homes and the council has warned they will be forced to leave because the building is not safe.
"The fact that all samples so far have failed the tests underlines the value of the testing programme we have set up with the Building Research Establishment to get samples checked properly in the laboratories".
"I have a disabled mother, I have animals in my property - they are not doing anything and no-one is telling us anything - it is ridiculous".
According to the council: "Both have experienced serious fires in recent years and in both cases the fires were contained within individual flats and did not spread anywhere else, suggesting that the design of the building, the method of installing the cladding and the materials used, stood up to the fire and prevented its spread to other parts of the building".
"Together we're making sure that the resources are there to ensure that what is needed to keep people safe is being done".
Cladding has been removed from tower blocks in Sunderland following testing.
The tower blocks have not been evacuated while the work takes place.
"We want to work with residents who are yet to evacuate and strongly encourage them to leave their homes and fix up temporary accommodation".
Some 650 homes were evacuated, forcing hundreds of people to hastily pack suitcases and ask to stay with friends and relatives, or take shelter in hotels or a leisure center where inflatable mattresses were set up until a more permanent solution could be provided.
"My thoughts are with residents being evacuated in Camden while their homes are made safe tonight", she said via her official UK Prime Minister account.
"How am I going to do that if I am somewhere far?"
Besides the cladding concerns, he noted, residents want the council to install sprinklers and fire alarms, which are now absent in the high-rise apartments, as well as provide fire blankets. "We are looking at all health and safety and fire safety offenses, and we are reviewing every company at the moment involved in the building and refurbishment of Grenfell Tower".
"You don't get everyone to leave this quickly". "I had a fire safety check done today", she told Sky News.
