Planning a home extension in Norfolk? It’s an exciting prospect! But before you start knocking down walls, it’s crucial to understand the ins and outs of planning permission. Navigating the rules can seem daunting, but this guide will simplify the process, giving you the knowledge you need to confidently move forward. At S. Clark Builders, we’re experienced in helping Norfolk homeowners through every stage of their extension projects, including the planning process.

1. Do I Need Planning Permission? – The Key Question

The first question most homeowners ask is: “Do I need planning permission for my extension?” The answer isn’t always a straightforward yes or no. While some projects require a full planning application, others fall under “permitted development” rights, allowing you to make certain changes to your home without formal approval.

It’s vital to remember that permitted development rights have limitations and differ for all homes. Factors like your property type, its location, and the scope of your proposed extension will all influence whether you need planning permission. Also, keep in mind that different local planning authorities cover various parts of Norfolk, including North Norfolk District Council, Broadland District Council, Borough Council of King’s Lynn and West Norfolk, Breckland Council, Great Yarmouth Borough Council, Norwich City Council and South Norfolk Council. You’ll need to check with the specific council relevant to your property. Getting this wrong can lead to problems down the line, so checking is always recommended.

2. Understanding Permitted Development Rights in Norfolk

Permitted development rights are rules allowing homeowners to carry out certain types of work without needing to apply for planning permission. However, these rights come with specific criteria that must be met. Here’s a simplified overview of the key permitted development rules for common extension types in Norfolk:

Important Note: These are simplified examples. The permitted development rules are more complex, and numerous conditions may apply.

Disclaimer: Always check the specific regulations with your local council before starting any work.

 

Single-Storey Rear Extensions

Maximum Depth: Up to 4 metres for detached houses and 3 metres for other types of houses (e.g., semi-detached, terraced)

Maximum Height: Up to 4 metres.

Eaves Height: The eaves (where the roof meets the wall) cannot be higher than the eaves of the existing house.

Distance from Boundaries: If the extension is within 2 metres of a boundary, the maximum eaves height is limited to 3 metres.

 

Double-Storey Rear Extensions

Maximum Depth: Up to 3 metres.

Maximum Height: Must not exceed the highest part of the existing roof.

Distance from Boundaries: Must be at least 7 metres from the rear boundary.

Materials: The materials used should be similar in appearance to the existing house.

 

Side Extensions

Maximum Width: Must not exceed half the width of the original house (as it was first built or as it stood on 1 July 1948).

Maximum Height: Up to 4 metres and single storey only.

Distance from Boundaries: No closer to a boundary than 3.5 metres.

Materials: The materials used should be similar in appearance to the existing house.

 

Loft Conversions

Volume Allowance: Up to 40 cubic metres of additional roof space for terraced houses and 50 cubic metres for detached and semi-detached houses.

Roof Plane: Must not extend beyond the plane of the existing roof slope that faces a highway.

Dormer Windows: Restrictions on size, position, and materials. They must not be higher than the highest part of the existing roof.

 

Conservatory Extensions

Maximum Height: Cannot be higher than the highest part of the existing roof.

Distance from Boundaries: Restrictions on how close they can be to boundaries.

Coverage: Restrictions on the percentage of the property’s area that can be covered by extensions or other buildings.

3. Special Rules for Designated Areas and Listed Buildings

If your property is in a designated area or is a listed building, stricter planning rules apply:

 

Conservation Areas

What is a Conservation Area? These are areas of special architectural or historic interest where it’s desirable to preserve or enhance the character or appearance. Many towns and villages in Norfolk have Conservation Areas.

Impact on Planning: Permitted development rights are significantly more restricted. You’ll likely need planning permission for most extensions and alterations.

 

Areas of Outstanding Natural Beauty (AONB)

What is an AONB? These are areas designated for their exceptional natural beauty, such as the North Norfolk Coast AONB.

Impact on Planning: Development is more strictly controlled to protect the landscape. Permitted development rights are limited, and planning applications are subject to closer scrutiny.

 

Listed Buildings

What is a Listed Building? These are buildings of special architectural or historic interest, graded as Grade I (highest importance), Grade II*, or Grade II. Norfolk has many listed buildings, particularly in its historic towns and villages.

Impact on Planning:  Any work that affects the character of a listed building, whether internal or external, requires Listed Building Consent. This is separate from planning permission.

• Natural England website for information on AONBs
• Conservation Areas – North Norfolk, King’s Lynn & West Norfolk, Broadland & South Norfolk, Breckland.

 

4. How to Apply for Planning Permission in Norfolk

If your project doesn’t fall under permitted development or is in a designated area, you’ll need to apply for planning permission. Here’s a step-by-step guide:

 

Step 1: Pre-Application Advice (Optional but Recommended)

Most local councils offer a pre-application advice service. This allows you to discuss your proposal with a planning officer before submitting a full application. It’s a valuable opportunity to get feedback, identify potential issues, and increase your chances of success.

 

Step 2: Prepare Your Application

A complete planning application typically includes:

• Detailed Drawings and Plans: These should show the existing building and the proposed extension from all relevant angles, including elevations, floor plans, and a site plan.
• Location Plan: Showing the location of your property in relation to surrounding roads and properties.
• Site Plan: A detailed plan of your property showing the proposed extension, boundaries, and any other relevant features.
• Design and Access Statement: This document explains the design principles behind your proposal and how it addresses issues like accessibility. It’s often required for larger extensions or those in designated areas.
• Other Supporting Documents: Depending on the project and location, you may need to provide additional reports, such as ecological surveys, heritage statements, or tree surveys.

 

Step 3: Submit Your Application

You can submit your application online via the Planning Portal or directly to your local council.

 

Step 4: Pay the Application Fee

Planning applications require a fee, which varies depending on the type and scale of the development.

 

Step 5: Consultation Period

Once your application is validated, the council will undertake a consultation period, typically lasting 21 days. They will notify your neighbours and other relevant bodies (e.g., the parish council, highways authority) and invite them to comment on your proposal.

 

Step 6: Decision

The council will assess your application against their planning policies and any comments received during the consultation period. They will usually make a decision within 8 weeks (or 13 weeks for major developments).

Possible Outcomes:

• Approval: Great news! You can proceed with your project as planned.
• Approval with Conditions: You can proceed, but you must comply with certain conditions specified by the council. These conditions might relate to materials, design details, or landscaping.
• Refusal: Your application has been rejected. The council will provide reasons for the refusal. You have the right to appeal the decision or submit a revised application.

 

5. What Happens if I Build Without Permission?

Building without the necessary planning permission is a risky move. If your local council discovers unauthorised development, they can take enforcement action. This could involve:

• Enforcement Notice: Requiring you to make alterations to the work or even demolish the extension to comply with planning regulations.
• Fines: You could face significant fines for breaching planning rules.
• Difficulty Selling: Having unauthorised development on your property can make it difficult to sell in the future, as potential buyers will be wary of the legal implications.

It’s simply not worth the risk. Always ensure you have the correct planning permission (or confirmation that it is not required) before starting any building work.
