  • Portable buildings that are an extension of an existing building may not need Planning Permission.
  • If the structure of the portable building is less than 25% of the original by volume.
  • The building is shorter in height than the original building.
  • The Temporary Building is directly relevant to the purpose of the original structure.

When Planning Permission Is Required

  • The building materially affects the external appearance of the building.
  • The building exceeds 25% of the total area available on the site, or in the case of a warehouse or factory extension, is more than 25% of the size of the original building.
  • The temporary building is closer than 5m to the site’s boundary.
  • The building significantly reduces the amount of land available for parking and/or manoeuvring vehicles.
