Housebuilder Davidsons Homes and property development and investment company L&Q Estates have submitted an outline planning application for the homes at Overstone Green.
The scheme would also include a new section of the A43 dual carriageway; up to 5.95-hectares of commercial uses; a primary school; public open space; and associated infrastructure.
According to the applicants, the development is part of a wider project intended to deliver around 3,500 new homes, ten hectares of employment land, two new primary schools, convenience stores, health care facilities, a community centre, sport and leisure facilities and improvements to the local transport and road infrastructure.
The scheme forms the northern part of the Northampton North Sustainable Urban Extension which was allocated in the West Northamptonshire Joint Core Local Strategy Local Plan in 2014.
Outline planning permission for the southern part of the project, which is set to comprise up to 2,000 homes, was granted in 2015.
A decision is expected to be made by Daventry District Council in the summer, according to the applicants.
In December, a 525-home urban extension to Northampton was given the go-ahead.
And in October last year, plans were approved for another urban extension to the town.
