Planning a Home Extension in Worthing? Here’s What to Consider
A well-designed home extension is one of the most effective ways to add more space, improve your layout and increase the value of your property — without the cost and stress of moving. In Worthing, where many homes benefit from generous plots, side access and underused garden areas, extensions have become one of the most popular ways to upgrade and modernise a home.
Whether you’re thinking about a larger kitchen, an extra bedroom or a brighter, open-plan living space, this guide covers everything you need to know before planning a home extension in Worthing.
Why Home Extensions Are So Popular in Worthing
Worthing offers a wide variety of property styles — from traditional homes in Broadwater and Tarring to 1930s semis in Goring and modern estates in Durrington and Findon. Many of these properties are perfectly suited to extensions thanks to:
-
- Generous gardens
-
- Side access ideal for single-storey extensions
-
- Outdated internal layouts that benefit from open-plan design
-
- Older kitchens and dining rooms that can be combined into modern spaces
Local homeowners often extend to create:
-
- Open-plan kitchen/dining areas
-
- Additional bedrooms or home offices
-
- More storage or utility space
-
- Larger family living rooms
-
- Garden-facing spaces with bi-fold doors
-
- Rear extensions leading into landscaped gardens
Done well, an extension can completely transform how your home feels and functions.
Types of Home Extensions in Worthing
Single-Storey Rear Extensions
The most popular choice for modernising 1930s and semi-detached homes in Goring, Broadwater and Durrington. Ideal for creating open-plan kitchens and living areas.
Double-Storey Extensions
Perfect for adding bedrooms and bathrooms while also expanding downstairs space. Great for families needing more room without moving.
Side Extensions
Many Worthing semis and detached homes have unused side strips — ideal for utility rooms, kitchens or additional living space.
Wraparound Extensions
For maximum transformation, combining both rear and side spaces to create a large, open-plan layout.
Key Things to Consider When Planning an Extension
1. Planning Permission & Local Regulations
Many single-storey extensions fall under permitted development, but it depends on height, materials, boundaries and roof design. Worthing Borough Council is generally reasonable with extension approvals, but a consultation or early check is always recommended.
2. Structural Engineering
Removing external walls or opening up rooms usually requires RSJs (steel beams). Professional structural design ensures everything is safe and compliant.
3. Heating, Plumbing & Electrics
Larger kitchens and open-plan layouts often require:
-
- New radiators or underfloor heating
-
- Updated plumbing
-
- Additional sockets and lighting
-
- Consumer unit upgrades
Planning these early prevents delays later in the build.
4. Natural Light
Roof lanterns, skylights and rear bi-fold doors are extremely popular in Worthing and help make new spaces feel bright and open.
5. Budget & Timescales
Costs vary based on design, materials and structural requirements. A clear scope early on helps keep everything on track.
