Brabazon is one of 7 new towns (although some are more like a new district on edge of an existing conurbation) in today's Government announcement
Built for the future from the ground up, the next generation of new towns will create well-connected new communities with homes, jobs, schools, green space and transport links planned from the start.
Each proposed location is expected to deliver at least 10,000 homes, with several delivering 40,000 or more in the decades to come.
