Understanding Permitted Development: Maximum Size You Can Build Without Planning Permission in UK

Introduction

As the demand for space and living accommodations continues to evolve, property owners in the UK often seek opportunities to expand their homes. The concept of permitted development offers a valuable avenue for achieving this goal without the complexities of obtaining planning permission. Diogel Architecture is here to provide comprehensive guidance on the maximum size you can build without planning permission in the UK, ensuring your property transformation is seamless and compliant.


Permitted Development Explained

Permitted development grants property owners the freedom to undertake certain types of development without the need for formal planning permission. These developments are subject to specific limitations and conditions set by the government. This streamlined process is especially valuable when considering extensions or additions to your property.


Maximum Size Allowed

In the UK, the size restrictions for permitted development vary depending on the type of development and its location. However, one of the most common and sought-after projects, a single-storey rear extension, has specific parameters to ensure compliance:


  1. Detached and Semi-Detached Houses: The maximum allowable depth for a single-storey rear extension is typically 4 meters.

  2. Terraced Houses: For terraced houses, the maximum extension depth is 3 meters.

  3. Height and Eaves: The maximum eaves and ridge height of the extension should not exceed the existing house.


Other Considerations

It's essential to bear in mind that permitted development rights are subject to various conditions. The extension must not cover more than 50% of the total garden area, and it should not extend beyond the original rear wall of the house. Additionally, materials used in the extension should match the existing property to maintain its aesthetic harmony.
