The housebuilder will press on with the first 199 homes at the 178-acre site after receiving planning approval from Wigan Council.
Countryside’s consent for the opening phase of the project includes 87 affordable homes, to be delivered by Great Places Housing Group, with a further 112 properties for open market sale.
The wider site has outline consent for around 1,800 homes, a district centre, infrastructure, and green space. Work on the first homes is expected to start early next year.
As part of the project, Countryside will also invest approximately £1m in a section of the planned new link road between J26 of the M6 and J5 of the M61.
The site to the south east of Wigan is made up of mostly vacant land and is bordered by two main roads, the A577 to the north and A578 to the west with Westleigh High School to the south east of the site.
Countryside acquired the site in a process run by CBRE in 2018. The site had been promoted by North Leigh Park Group, part of Guernsey-based Long Port Properties, but Long Port put the business into administration in December 2016.
Cllr David Molyneux, leader of Wigan Council said: “North Leigh Park is a key brownfield site outlined in our local plan and regeneration strategy and without this development, there would be a lot of pressure put onto our greenbelt.
“It’s good news that this most recent planning application has been approved by committee members. Not only will it help us to meet housing demand over the next five years, but it will also provide local people with quality, affordable housing, which is another top priority for us.
“We will continue to work with Countryside to ensure that this development is one which suits local need and, just like on this occasion, any further applications will be decided in line with local and national planning policy.”
Lichfields advised countryside on its planning application.
