What is being built near Southbourne?
Land Registry recorded 36 sales of newly built homes in Southbourne between January 2022 and August 2026: 3 in 2022, 1 in 2023, 21 in 2024, 10 in 2025 and 1 in 2026 (to August). New estates take several months to appear in its records, and their new postcodes longer, so homes finished this year may not show yet. Chichester District Council's brownfield land register (last updated December 2024) lists no site within 500 metres of its postcodes; it covers land that has been built on before, not fields. Where new homes go is set by Chichester District Council's local plan, the Local Plan 2021 to 2039, adopted in August 2025; a new one is being prepared. The council has also drafted a separate plan allocating land for new homes at Southbourne.

Can I extend or alter a home in Southbourne?
Usually, within the national limits, but not everywhere: 50 of Southbourne's 215 postcodes are in the Prinsted conservation area or Chichester Harbour National Landscape, where homeowners can do less without planning permission. Of those, the Prinsted conservation area covers one and the National Landscape 50, and some postcodes are in more than one. There, an extension to the side, a back extension of more than one storey, a loft extension that adds to the roof and cladding the outside all need planning permission. Historic England lists 25 buildings within 100 metres of a Southbourne postcode, among them one at grade II*; any work that changes a listed building's character, inside or out, needs listed building consent. Chichester District Council has not published its Article 4 directions or its tree preservation orders to the government's planning data service, so check with it before starting work. In a conservation area, cutting down or pruning a tree above a small size needs six weeks' notice to the council. Flats and maisonettes have no householder permitted development rights. Whether a particular job needs permission depends on the home: the council can say, and a lawful development certificate puts it in writing.
