Foundations in Worthing
Foundations are the below-ground concrete structure that transfers the load of a building safely into the ground, with the type — strip, trench-fill or raft — and depth determined by ground conditions, nearby trees and the load of the structure above.
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
Foundations in Worthing: FAQs
Do you provide foundations 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.
How deep do foundations need to be?
Depth depends on ground conditions, the load of the structure and proximity to trees or drains — a straightforward strip foundation might be around 1m deep, but clay soils near mature trees can require significantly deeper trench-fill foundations. This is confirmed by site investigation and agreed with Building Control.
Does Building Control need to inspect the foundations before concrete is poured?
Yes. An open-trench inspection is a standard Building Control stage, carried out once excavation is complete and before concrete is poured, to confirm the ground conditions and depth match what was approved.
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.
