Developers are holding an exhibition on plans to build 1,050 homes in Sudbury.
The 329 acres (133 hectares) of open land at Chilton was adopted for development by Babergh District Council in 2006.
The housing developer Redrow said the public consultation is being staged before it submits an outline planning application.
The development is in the council's draft core strategy which is still in the consultation stage.
Chris Sparks, Redrow's land director, said: "People are very positive and we've engaged with various parish councils and it's really about getting to the detail to integrate this scheme within Sudbury to the benefit of the local community.
"We've been in consultation with parishes and stakeholders and there's a very clear message that this housing is required.
"We're seeing some strong growth [in the housing market] in the South East and we're seeing sales moving forward."
Redrow said the council has a policy of making sure 35% of housing on new developments is affordable (a mix of shared ownership and social housing), but the figure has yet to be agreed for Chilton Woods.
Redrow's current plans include employment and shopping zones, a school and improvements to road links.
A consultation exhibition into the plans is being held at All Saints Middle School, Sudbury, until Saturday.
