A local authority has halved its target for the number of new homes required to be built in the region.
Mid Sussex District Council said it would aim to build 370 new homes every year rather than its previous target of 855.
The move comes after the government scrapped central housing targets for local councils in July.
Council leader Garry Wall said previous targets set by the Labour government had been unrealistic.
He said: "We have always maintained our opposition to the arbitrary and unrealistic housing numbers imposed on us but until recently we remained bound by the system."
Mr Wall said scrapping targets had given the council the opportunity to act in the best interest of the community.
Currently, about 400 new homes are built in the area each year.
Labour has said the scrapping of central housing targets could directly result in the loss of 160,000 new homes.
