The properties, for over-60s, will be delivered by Audley Group and Senior Living Investment Partners (SLIP) and operated by Audley Group.
They will be the first in London to operate under Audley Group’s Mayfield Villages brand.
Residents will have access to 17,000 sq ft of amenities, including a village hall, a health and wellness centre, a residents’ lounge, outdoor gardens, and a café/bistro open to the public.
Tom Goodall, chief executive director at developer and Barnet Council partner Related Argent, said: “We are delighted that the first retirement living homes at Brent Cross Town have been given the go-ahead.
“This builds on the continued inward investment secured over the last 12 months and accelerates our bold vision to create an intergenerational community with diverse housing options.”
Barnet Council deputy leader Cllr Ross Houston, who is responsible for homes and regeneration, said: “Brent Cross Town is being carefully designed to meet the needs of our residents now and in the future.
“The introduction of new high-quality later living accommodation will contribute to the vibrant mix of housing options already becoming available in the new neighbourhood.”
Brent Cross Town will eventually have 6,700 new homes, 3m sq ft of offices, a high street, schools, a university, and 50 acres of parks and playing fields.
