Vistry Group has agreed contracts to build 233 more homes at its Western Gate site in Harpole, near Northampton.
This brings the total built so far to 1,070 homes out of a planned 1,900 at Norwood Farm.
The homes will include 83 affordable properties, 80 for the private rented sector, and 70 for the open market.
West Northamptonshire Council recently approved reserved matters for phase two, allowing Vistry Group to start on 278 more family homes.
Of these, 139 will be sold on the open market and 139 will be affordable homes through Vistry Group’s partnership with Platform Housing Group.
Vistry Group has also signed its first deal with Zen Housing, which will own and manage 18 affordable homes.
Andrew Harvey, managing director of vistry south central midlands, said: “I am thrilled to announce the completion of contracts for an additional 233 mixed-tenure homes at Western Gate and our first contact with Zen housing.
“This brings the total to 1,070 of the 1,900 new properties planned at Norwood Farm.
“Our commitment goes beyond house building, with £9 million allocated to bolstering services for both new current residents.”
John Okell, investment director at Zen Housing, said: “The contract for the additional homes coincides with receiving reserved matter to start work on a further 278 properties for the affordable and open markets.
“This clearly shows Vistry’s dedication to meeting housing needs by building homes across multiple tenures to an exceptional standard, creating a thriving and sustainable community.
“We are delighted to mark the start of our partnership with Vistry Group on this phase of homes at Western Gate.”
Okell added: “These 18 high-quality affordable homes reflect our commitment to delivering sustainable, well-connected communities.
“Executing the deal in just five weeks ahead of completions in August highlights the strength of collaboration between our teams.
“We look forward to supporting the wider Norwood Farm vision through tenure-diverse, community-focused delivery.”
