Planning Permission for Garden Buildings in the UK

This guide provides basic information based on UK regulations but is not exhaustive. Planning laws can change, so always verify current guidelines with your local planning authority or check official government websites.

General Guidelines for Garden Buildings

  1. Permitted Development Rules

    • Garden buildings are often covered under permitted development, which allows construction without planning permission if conditions are met.
    • Size Limits:
      • Max height: 2.5m if within 2m of a boundary; otherwise, 4m for dual-pitched roofs or 3m for other roof types.

  2. Location

    • Must not be placed in front of the principal elevation of the house facing a highway.
    • Not allowed within the grounds of a listed building.

  3. Usage

    • For incidental purposes (e.g., home office, gym, or storage).
    • Separate self-contained living spaces require planning permission and must meet building regulations.

  4. Designated Areas

    • In conservation areas, national parks, or similar, special rules apply. Check with your local authority.

  5. Materials and Appearance

    • Should complement the main house; timber structures are typically acceptable.

  6. Separate Annexes

    • Always require planning permission, even within the property boundary.

Important Notes

  • Regulations may vary by location and purpose.
  • Seek advice from your local planning authority or a planning consultant if unsure.
