For many London homeowners, extending their property is the perfect solution to gain more space without the need to move. However, navigating planning permissions can be daunting. This is where a permitted development extension becomes a game-changer. At Simply Extend, London’s leading extension specialists, we help you make the most of your home by guiding you through the permitted development process and delivering stunning extensions that comply with regulations.

What Is a Permitted Development Extension?

A permitted development extension allows homeowners to extend their property without the need to apply for full planning permission, provided the work meets specific government regulations. These rights were introduced to streamline the process of home improvements, making it quicker and easier to create extra space.

Typically, permitted development rights cover certain types of single-storey rear extensions, loft conversions, and sometimes side extensions, subject to size and design limits.

Key Benefits of a Permitted Development Extension

  1. Faster Approval Process
    Since no full planning permission is needed, the project timeline is often much shorter. This means you can enjoy your new space sooner.
  2. Cost Savings
    Avoiding full planning applications reduces fees and administration costs, making your extension more affordable.
  3. Simplified Process
    With clear government guidelines, permitted development extensions reduce the complexity of planning, while still ensuring quality and safety standards.

What Are the Rules for a Permitted Development Extension?

While permitted development rights are generous, they come with specific limits, including:

  • Size Restrictions: Rear extensions must not extend more than 3 meters for terraced houses and 4 meters for detached/semi-detached homes without needing approval.
  • Height Limits: Single-storey extensions must not exceed 4 meters in height, and two-storey extensions have stricter limits.
  • Materials: Extensions should use materials that match or complement the existing building.
  • Location: Extensions must not project beyond the rear wall of the original house, and certain rules apply near boundaries.
  • Listed Buildings and Conservation Areas: Properties in these areas often have restricted or no permitted development rights.
