DEVELOPERS want to build 1,700 houses in Tewkesbury, split between the Mitton and Mythe areas.
Part of the scheme, to build 1,100 homes north of the Mitton estate, has already been in the pipeline for some time.
But the other half of the proposal, to build 600 homes on land around the Mythe, has not been raised publicly until now.
Brothers John and Nick Pitcher, along with the Ball family from Bradley's Farm, want to make land around Mythe Farm available for development. It would stretch from Stanchard Pit in the south, up Mythe hill, along the A38 and to Bradley's Farm in the north.
No planning applications for either scheme are imminent, but both will be revealed in detail at a public exhibition in the town hall from 11am to 7.30pm on Wednesday.
Mark Sackett, the planning consultant for both developers, said: "In respect of how Tewkesbury should grow, the promoters of Mitton and Mythe contend that their proposals, being so close to the town centre, will help to support the aspirations for the town as presented in the borough council's emerging town centre master plan.
"In contrast, the alternative of locating strategic housing growth east of the M5 at Ashchurch is considered unlikely to benefit the town, with new residents choosing to travel to free parking in the north west of Cheltenham for shops and services rather than Tewkesbury High Street."
He said if planning permission was granted, the developers would pay for community improvements including covering the estimated £2 million cost of completing the northern relief road between Morrisons and Bredon Road, and reconstructing the Bredon Road culvert over the Carrant Brook to ease flooding.
Other proposed projects include a new primary school for Mitton, a 220-space public car park off Mythe Road and new rise and fall town moorings in Back of Avon.
Mr Sackett stressed that large areas of the green fields earmarked for the schemes would be left undeveloped for recreation and nature conservation.
Dave Witts, of the Severn and Avon Valley Combined Flood Group, said he feared the Mythe development could increase flooding in Tewkesbury.
"They want to build between two flood plains. The effect this would have on the flood plains would be horrendous," he said. "Once again, profit overrules risk to the community."
But Mr Sackett claimed flooding would be resolved through drainage.
North Tewkesbury Land Consortium and Croome Estate Trustees are behind the Mitton scheme.
The 1,700 homes are not part of housing schemes for the area being put together by Tewkesbury Borough Council and Wychavon District Council.
