MMC will be used to build the homes, 30% of which will be affordable
The housebuilder said it would use modern methods of construction to build the homes as part of the third phase of the scheme, with Homes England having provided the infrastructure for the mixed-use site.
Just under a third of the homes, which will range from a mix of flats and one to five-bedroom houses, will be affordable.
The initial three phases on the scheme are due to deliver 580 homes.
The first phase was developed by David Wilson, while work on phase two was undertaken by Crest Nicholson.
Tattenhoe could eventually host more than 1,300 homes across the near-20-acre site, subject to planning.
Last month it was announced Countryside would build more than 160 homes at the Newhall development in Harlow, Essex (pictured above), after architect BPTW secured planning.
