Homes England was also granted permission for a community sports facilities, three local retail centres, a four-hectare business park, two primary schools, a secondary school, play areas, open space, and other associated infrastructure.
The plans for the Burgess Hill Northern Arc development propose a policy-compliant 30 per cent affordable housing contribution and includes 60 units of extra care accommodation and 13 permanent gypsy and traveller pitches.
Homes England submitted the application in January this year. The 184-hectare site is allocated for the development of housing, employment and community facilities in the Mid Sussex District Plan, which was adopted in March 2018.
Recommending approval, Mid Sussex planning officers advised that the development "would provide significant economic benefits" and "make a very important contribution to the district's housing supply".
Officers noted that the proposed four hectares of employment provision fell short of the 25 hectares required by the local plan. But they said this shortfall had been deemed acceptable in a masterplan for the site that was adopted by the council in September last year.
They advised of "a number of adverse effects that need to be taken into consideration", including "less than substantial harm to nearby heritage assets" and "the loss of some trees and hedgerows".
However, officers said planning conditions would secure mitigation measures to reduce the impact on heritage assets and secure replacement trees.
Overall, officers concluded: "The benefits of this development … significantly outweigh the adverse impacts that will in any event be mitigated for as far as possible."
