Conversions in Worthing
A property conversion changes the use of existing space — such as a loft, garage, barn or outbuilding — into new habitable accommodation, and typically involves structural alterations, insulation upgrades, new services, and Building Regulations approval, with planning permission or listed building consent needed in some cases.
In Worthing, that covers Tarring, Broadwater, Durrington, Goring-by-Sea, Findon Valley, Heene. Worthing is a seafront town with a strong Edwardian and interwar residential character, notable Art Deco buildings along the seafront, and a wide range of housing types stretching inland towards the South Downs.

FAQs
Conversions in Worthing: FAQs
Do you provide conversions across all of Worthing?
Yes, we cover the BN11 and BN12 and BN13 and BN14 postcode areas in full, including Tarring, Broadwater, Durrington, Goring-by-Sea, Findon Valley, Heene.
Do I need planning permission for a loft conversion?
Many loft conversions fall under permitted development if they stay within volume limits and do not extend beyond the roof plane at the front. Dormers, roof terraces, and conversions on designated land or flats usually need planning permission. We confirm this at feasibility stage.
What head height do I need for a loft conversion?
As a general guide, a minimum ridge height of around 2.2 to 2.3 metres is usually needed for a workable staircase and standing space, though this varies with roof pitch and layout. We measure this on survey before advising on feasibility.
Are Worthing's seafront buildings protected?
Many of the town's notable Art Deco and Edwardian seafront buildings are listed or within conservation areas, which affects what external changes can be made without consent. We check this for individual properties.
