Planning a house extension is exciting but you need to navigate the legal bits to make it run smoothly. One of those bits is planning permission. This guide will take you through everything you need to know about house extension planning permission from the basics to the application process.
House extensions are a great way to add more living space and functionality to your home. But before you can start building you need to make sure your project complies with local rules. Understanding and getting planning permission is a big part of that. This article will cover what planning permission is, when you need it, how to apply for it and tips for a successful application.
1. What is Planning Permission?
Planning permission is the formal approval from your local council to do building works or changes to your property. This process checks that the proposed development is right for the area and fits with local planning policies.
Key points to know about planning permission:
- It looks at the impact on the surrounding environment and community.
- It checks that the development fits with local development plans and policies.
- It protects the character of the area.
2. When Do You Need Planning Permission?
Not all house extensions need planning permission. Whether you need it depends on several things including the size, height and location of the extension. Generally you will need planning permission if:
- The extension exceeds certain size limits (e.g. extends more than a certain distance from the original house).
- The extension changes the principal elevation of the house.
- The extension increases the overall height of the property.
- The extension is near a boundary or road.
But some extensions fall under “permitted development rights” which means you can do certain types of extensions without needing planning permission. You need to check with your local planning authority to see if your project qualifies as permitted development.
3. Permitted Development Rights
Permitted development rights allow homeowners to do certain building works without needing planning permission. These rights are subject to conditions and limitations such as:
- Size and scale restrictions (e.g. single storey extensions must not exceed a certain height and depth).
- Location restrictions (e.g. extensions can’t be in front of the principal elevation).
- Use of materials that are the same as the existing house.
These rights may vary depending on where you live, if your property is listed or if you live in a designated area such as a conservation area or national park.
4. How to Apply for Planning Permission
Applying for planning permission involves:
- Pre-application Advice: Consult with your local planning authority for guidance and advice on your proposal. This can help identify potential issues early on.
- Prepare Your Application: Collect all necessary documents including detailed plans, drawings and supporting statements.
- Submit Your Application: Submit the completed application form and documents to your local planning authority. This can usually be done online.
- Pay the Application Fee: A fee is usually required for processing the application. Check with your local authority for the amount.
- Public Consultation: The planning authority will notify neighbours and other stakeholders and allow them to comment on the proposal.
- Decision: The planning authority will review the application and make a decision, usually within 8-12 weeks. You will receive a decision notice with the outcome.
5. Top Tips for a Successful Application
To increase your chances of a successful application:
- Talk to Neighbours: Discuss your plans with neighbours to address any concerns and get their support.
- Get a Professional: Consider hiring an architect or planning consultant to prepare your application and make sure it meets all the requirements.
- Follow the Rules: Follow local planning guidelines and policies to avoid common mistakes.
- Provide Detailed Plans: Submit full and accurate plans including elevations, site plans and design statements.
- Consider the Impact: Show how your extension will benefit the area and mitigate any negative impacts.
6. What to Do if Your Application is Refused
If your planning application is refused you have:
- Re-submit with Changes: Address the reasons for refusal and re-submit.
- Appeal: If you think the refusal was unfair you can appeal to the Planning Inspectorate. This can be a long and complicated process.
- Get Professional Advice: Consult a planning consultant or architect to explore alternatives or modifications to your proposal.
