How Big Can a Shed Be Without Planning Permission?

shed planning permission guide

When planning to add a shed to your property, understanding the regulations and restrictions around its size is crucial to avoid any legal complications. In the UK, planning permission for sheds can be a complex issue, depending on various factors such as location, size, and intended use. Here’s a comprehensive guide to help you navigate the rules regarding shed size and planning permission.

General Rules for Shed Size

  1. Height Restrictions:
    • The maximum height for a shed is generally 4 meters for a dual-pitched roof and 3 meters for any other type of roof. If the shed is within 2 meters of the property boundary, the maximum height is restricted to 2.5 meters.
  2. Floor Area:
    • The total area of all outbuildings, including sheds, must not cover more than 50% of the total area of the land around the original house. The “original house” refers to the house as it was first built or as it stood on 1 July 1948 (if it was built before that date).
  3. Location:
    • Sheds must be placed at least 2 meters away from the property boundary to avoid planning permission requirements. If you want to place the shed closer, the height restriction of 2.5 meters applies.
  4. Purpose and Use:
    • The shed must not be used as a living space. It should be used for purposes incidental to the enjoyment of the dwelling house, such as a garden shed, workshop, or storage.

Special Considerations

  1. Conservation Areas:
    • If your property is in a conservation area, there are additional restrictions. Planning permission will be required if the shed is to be located on land between the side of the house and the boundary.
  2. Listed Buildings:
    • If your house is a listed building, you will need to obtain listed building consent for any alterations, including the addition of a shed.
  3. Design and Materials:
    • The design and materials of the shed should be in keeping with the surrounding environment. In some cases, local authorities may impose restrictions to ensure the shed does not adversely affect the aesthetic of the area.

Getting Planning Permission

If your shed exceeds any of these limits or if there are special circumstances such as location in a designated area, you will need to apply for planning permission. The process involves submitting a detailed plan of the proposed shed, including its dimensions, materials, and exact location on your property.
