How to Plan a Home Extension in Norfolk: A Complete Step-by-Step Guide
A home extension is one of the best ways to increase space, improve functionality, and boost the value of your property. Whether you need a larger kitchen, an extra bedroom, or a full two-storey addition, careful planning is essential — especially in a county like Norfolk, where planning rules and property types vary widely.
Here is a clear, step-by-step guide to help you plan your Norfolk home extension with confidence.
1. Identify Your Goals and Budget
Before speaking with an architect or builder, outline what you want to achieve.
Ask yourself:
Do you need more living space?
Are you looking to increase your property value?
Will the extension be single-storey, double-storey, or side/rear facing?
What budget range are you comfortable with?
Most Norfolk extensions fall into ranges such as:
£50k–£75k
£75k–£100k
£100k–£150k+, depending on size and specification
Having a budget helps professionals guide you realistically.
2. Check Whether You Need Planning Permission
Many home extensions in Norfolk can be built under Permitted Development Rights, meaning no full planning application is needed.
However, planning permission may be required if:
Your home is in a conservation area
You live in a listed building
The extension is large or unusually shaped
You’re close to neighbouring boundaries
You want a two-storey addition
A good local builder or architect can tell you instantly whether you’ll need approval.
3. Hire a Local Builder Early
A common mistake is hiring a builder after the drawings are completed.
Instead, involve a local Norfolk builder early to:
Advise on realistic costs
Suggest design ideas
Prevent overly expensive or impractical plans
Speed up the overall process
Builders see what works every day — their guidance is invaluable.
4. Get Architectural Drawings & Structural Calculations
Next, you’ll need:
Architectural floor plans
Elevation drawings
Structural engineer calculations (for new steel beams, openings, etc.)
These are required before building control approval or construction can begin.
5. Submit to Building Control
Even if planning permission isn’t needed, Building Regulations approval is mandatory.
This ensures:
Structural stability
Fire safety
Energy efficiency
Proper drainage
Electrical and plumbing compliance
Your builder can handle this on your behalf.
6. Prepare for the Build
Work with your builder to plan:
Timelines
Access routes
Living arrangements
Material choices
Kitchen/bathroom placements
Heating and electrical layouts
Good preparation helps prevent delays once construction begins.
7. Construction Phase
The build typically includes:
Groundworks & foundations
Brick/block construction
Roofing
Windows & doors
First fix electrics and plumbing
Insulation & plastering
Second fix carpentry
Decoration and finishing touches
A reputable builder will keep you updated throughout every stage.
8. Final Inspection & Sign-Off
Once the extension is completed, Building Control will inspect and issue a compliance certificate.
Your builder should provide all manuals, warranties, and documentation.
9. Enjoy Your New Space
With the right builder and proper planning, your new extension will add comfort, functionality, and long-term value to your home.
