Planning permission Thinking of Extending but Don’t Know Where to Start?
Applying for planning permission can feel like a maze of rules, drawings, and approvals — but it doesn’t have to be overwhelming. Through our sister company, VisionaryPartners, we’ve guided many clients (and even ourselves) through the entire planning process, from first sketches to final approval. With the right preparation and a clear checklist, securing permission for your extension becomes far more straightforward.
If you’re planning an extension, getting planning permission can feel a bit daunting — but knowing what councils look for will save you time, stress, and possible delays. Here are the key things to keep in mind:
1. Planning Rules and Policies
- Permitted Development Rights: Some extensions don’t actually need planning permission if they stay within certain size and height limits. It’s always worth checking if your project qualifies.
- Local Policies: Every council has its own rules and design guides, so make sure your plans fit with what your local authority expects.
2. Size, Scale, and Design
- Keep your extension in proportion with the rest of the house.
- Use materials and styles that complement your home.
- Oversized or out-of-place designs are more likely to be turned down.
3. Impact on Neighbours
- Privacy: Avoid windows that overlook neighbouring gardens or bedrooms.
- Light: Make sure your extension won’t block sunlight to your neighbour’s home.
- Scale: Try not to design something that feels overbearing next door.
4. Positioning
- Front extensions are usually the most restricted.
- Side extensions, especially on corner plots, may need extra care to keep the street view attractive.
5. Listed Buildings & Conservation Areas
- If your home is listed, in a conservation area, or in an Area of Outstanding Natural Beauty (AONB), stricter rules apply.
- You may also need extra approvals, like Listed Building Consent.
6. Access and Parking
- Don’t reduce your parking space below the council’s minimum requirement.
- Make sure driveways and access routes stay safe and practical.
7. Environmental Considerations
- If you live in a flood zone, you might need a flood risk assessment.
- Councils often encourage eco-friendly design and materials, so factor this in where you can.
8. Building Regulations
- • Even if you don’t need planning permission, you will still need building regulations approval.
- This covers safety and technical standards like structure, insulation, fire safety, drainage, and electrics.
9. Supporting Documents
When you apply, you’ll usually need to provide:
- A site location plan and block plan
- Existing and proposed floorplans and elevations
- A Design & Access Statement (sometimes required)
- Application forms and fees
10. Neighbours & Consultation
- Councils usually notify neighbours, but it’s always a good idea to talk to them first.
- Getting them on side early can help avoid objections that might delay your application.
With all these points in mind, you’ll be much better prepared to get your plans approved and move forward with your dream extension.
