Structural Alterations in Worthing
A structural alteration, or knock-through, removes or alters a load-bearing wall — typically to join a kitchen and dining room — and requires structural calculations from an engineer, a supporting steel beam sized to the load, and Building Regulations approval before and after the work.
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
Structural Alterations in Worthing: FAQs
Do you provide structural alterations across all of Worthing?
Yes, we cover the BN11, BN12, BN13 and BN14 postcode areas in full, including Tarring, Broadwater, Durrington, Goring-by-Sea, Findon Valley, Heene.
Do I need planning permission to remove an internal wall?
Usually no — removing an internal load-bearing wall is normally a Building Regulations matter rather than a planning one, provided the property isn't listed and the work doesn't affect the external appearance. We confirm the position for your property at survey.
How do I know if a wall is load-bearing?
Load-bearing walls typically run perpendicular to floor or roof joists, sit above a wall or support on the floor below, or align with the roof structure — but this isn't reliable to judge by eye, so we assess it on-site and confirm with a structural engineer before any work starts.
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.
