Planning Permissions for Extensions in Surbiton: What You Need to Know
6 January 2025

Planning a home extension in Surbiton or nearby areas like Kingston, Wimbledon, Teddington, Twickenham, Cobham, or Leatherhead? Understanding planning permissions is a crucial step in ensuring your project complies with local regulations.


At Home Improvement & Construction Limited, we’re here to guide you through the process and help you achieve your dream home without unnecessary delays.

HICL insights - 4 - Planning Permissions for Extensions in Surbiton: What You Need to Know


1.  Do You Need Planning Permission?


Whether you need planning permission for your extension depends on several factors, including the size, location, and purpose of the project. Some extensions fall under "permitted development rights," meaning no formal planning application is required. However, these rights have limitations:


Key Considerations:

  • Size and Height: Single-storey extensions must not exceed four metres in height or extend beyond the rear wall of the original house by more than three metres (for attached houses) or four metres (for detached houses).
  • Location: Extensions on designated land (e.g., conservation areas) may require planning permission regardless of size.
  • Usage: Converting a garage or loft into living space may have different rules.


For detailed information on permitted development, visit the UK Government’s planning portal: www.planningportal.co.uk.



2.  Local Regulations in Surbiton and Surrounding Areas


Surbiton and its nearby towns, including New Malden, Raynes Park, Guildford, Woking, and Oxshott, are subject to local planning authority rules enforced by Kingston Borough Council and surrounding councils. If your property is in a conservation area or listed, stricter guidelines may apply.

To determine specific requirements, consult your local council’s planning department. For Surbiton, visit the Kingston Borough Council website: www.kingston.gov.uk.

3.  How to Apply for Planning Permission


If your project doesn’t fall under permitted development, you’ll need to submit a formal planning application. Here’s how:

  1. Prepare a Design Proposal: Work with experienced extension builders like HICL to create detailed drawings and plans.
  2. Submit an Application: Use the Planning Portal to file your application online. Ensure all required documents and fees are included.
  3. Await Approval: The process typically takes 8-12 weeks.


At HICL, we provide turnkey services, including handling planning applications for our clients in KT5, KT6, and beyond. Let's work together to simplify the process for you.


4. Common Reasons for Planning Permission Denials


Planning permission can be denied for various reasons, such as:

  • Extensions that overshadow neighbouring properties
  • Designs out of character with the local area
  • Lack of compliance with building regulations


Our team at HICL ensures your project is designed to meet all guidelines, reducing the risk of rejection.
