The Hackney-based practice won approval for 291 homes along with 425m2 of commercial and educational space within the Tottenham scheme last month.
Haringey Council’s decision completes the planning process for the wider neighbourhood.
Backed by a consortium of housing association Peabody, housebuilder Hill social enterprise Catalyst, the wider scheme will deliver up to 995 homes and 5,000m2 of other facilities on a former hospital site bought by the mayor of London from the NHS in 2018.
KCA’s masterplan, approved in the summer of 2023, features a series of buildings up to nine storeys high arranged around a ‘peace garden’ at the centre of the 7ha plot, which was previously part of St Ann’s Hospital.
Construction has since begun on phase 1A, which consists of 240 homes. Phases 1B and 2, covering another 464 residences, secured full consent last summer.
Now Haringey has approved the final phase, which will see the outstanding units delivered on the eastern edge of the site, next to the retained hospital.
About 56 per cent of the habitable rooms within the 291 homes in this third swathe of development will be affordable, according to planning documents.
A mixture of family houses, maisonettes and small tower blocks will be delivered.
Landscaping, public realm and play space will be provided at this stage, as well as pedestrian access to the hospital.
Across the wider scheme, 60 per cent of habitable rooms will be designated ‘affordable’, with some at London Living Rent levels, some for older adults and some dedicated to accommodating NHS key workers.
The masterplan is expected to be built out by 2030.
Work on another KCA Tottenham scheme is expected to begin next year. The practice’s 202-home Selby Urban Village was granted planning permission earlier this year.
