Loft Conversions in Worthing
A loft conversion converts an existing roof void into usable living space — typically a bedroom with en-suite — by adding a dormer or rooflights, strengthening the floor, forming a staircase and meeting Building Regulations for insulation, structure and fire escape.
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.

Edwardian and interwar semis and terraces make up much of the town's core housing stock, with Art Deco apartment buildings along parts of the seafront and postwar estates further inland. Rear extensions and loft conversions are common on the bay-fronted terraced and semi-detached housing typical of the town.
Planning considerations
Adur & Worthing Councils act as the local planning authority. Several seafront and town centre areas are conservation areas with notable Art Deco buildings, some of which are listed, affecting alterations to elevations and windows.

FAQs
Loft Conversions in Worthing: FAQs
Do you provide loft conversions 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 for a loft conversion?
Many loft conversions fall under permitted development if the added roof volume stays within set limits (typically 40m³ for terraced houses, 50m³ for semi-detached and detached) and materials match the existing house. Conversions on designated land, in conservation areas, or exceeding those limits need a full planning application, which we confirm at survey.
How much head height do I need for a loft conversion?
As a general guide, at least 2.2–2.3m from the top of the ceiling joist to the underside of the ridge gives a workable conversion, though this varies with roof pitch and the design chosen. We measure this precisely during the feasibility survey.
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.
