Bloor Homes has applied for planning permission from South Gloucestershire Council to build the giant new housing estate in Warmley, on the eastern outskirts of Bristol.
The North Warmley development would be built on fields in between the A420 London Road and Webbs Heath.
The fields are currently protected from development as the Green Belt, which stops urban sprawl, but this protection could soon be removed.
The plans include expanding the Warmley Forest Park by around 15 hectares, with better walking routes, new woodlands, wetlands and wildflower meadows.
This will open up currently private farmland to create extra space for the public to walk through.

Mike Kerton, planning director at Bloor Homes South West, said: “We’ve listened carefully to what matters most to people and top of that list was taking full advantage of turning currently private land into new public open space.
“Warmley Forest Park is already special, and this is our chance to make it even better.
“The park will be bigger and more accessible, with spaces for play, quiet walks, and wildlife to thrive.
“This is a plan for the long term, and there’s a lot still to shape.
“From the play areas and walking routes, to how we design the streets and homes, we’ll keep working with local residents and local groups to get the details right as we move forward.”
The area has already been designated for housing in the council’s draft Local Plan, which sets out how South Gloucestershire should develop over the next several years.
Councillors are due to decide whether to approve planning permission for the housing estate late next year.
If approved, construction could begin in 2029 with the last homes finally finished in 2039.
Two new parts of the forest park will be called the Siston Brook Valley Wetlands, with wildflower meadows, timber play areas and wetlands, and Goose Green Meadows, “designed for nature, views and wellbeing”.
Walking paths will link up with the wider countryside and the Bristol and Bath Railway Path, with two new bridges over Siston Brook and bat-friendly lighting.
Bloor Homes would pay towards improving local doctor and dentist services, to help ease the pressure of a growing population.
They would also pay towards improving bus services and cycling routes, so future residents wouldn’t have to rely on driving a car.
The development could include a care home for 75 elderly people. 30 per cent of the new homes would be affordable.
The planning application has already received several comments from members of the public, raising concerns about additional traffic, poor public transport and the loss of the countryside.
Traffic on the ring road is already congested, as well as the A420 running into the city centre.
One local resident said: “The proposed development would significantly increase traffic, which is already congested during peak times.
“Local services are already at capacity. The additional homes will place unsustainable pressure on these services.”
Another resident added: “Our roads are already heavily burdened, with congestion at peak times becoming increasingly unmanageable.
“Adding potentially thousands of new vehicles will only exacerbate traffic problems, increase pollution, and further strain road safety.
“There is also a well-known shortfall in secondary school places locally and early years places.
“The addition of hundreds of new families will put unsustainable pressure on our already overstretched education system, leaving many children without access to nearby schools or nurseries.”
Across South Gloucestershire, 22,500 new homes are expected over the next 15 years, including on several parts of the Green Belt.
The council has come under increasing pressure from the government to increase the number of new homes built in the district, given its rising population, ample space and how unaffordable housing prices have become in some parts.
