Garden Room Permitted Development

A Garden Room Without Planning Permission!

A Garden Room Without Planning Permission

In the vast majority of cases, homeowners are permitted to add a garden room to their property's outside space without seeking planning permission.

This is due to garden rooms typically falling under the category of 'permitted development,' provided they adhere to certain guidelines.

All our garden rooms have been thoughtfully crafted to align with the permitted development regulations, ensuring they comply with the legal standards and elimate any problems for our customers.

Garden Room Permitted Development

Garden Room Permitted Development

Outbuildings are considered to be permitted development and do not require planning permission, subject to a number of specific limits and conditions. These stipulations include restrictions on overall size, height, and placement relative to the property boundary, as well as the nature of the outbuilding's use.

Below, we detail these conditions to ensure your project complies with the current regulations. It is important to understand these guidelines before construction to ensure your outbuilding adheres to the permitted development rights.

  1. No outbuilding on land forward of a wall forming the principal elevation.
  2. Outbuildings and garages to be single storey with maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof.
  3. Maximum height of 2.5 metres in the case of a building, enclosure or container within two metres of a boundary of the curtilage of the dwelling house.
  4. No verandas, balconies or raised platforms.
  5. No more than half the area of land around the "original house"* would be covered by additions or other buildings.
  6. In National Parks, the Broads, Areas of Outstanding Natural Beauty and World Heritage Sites the maximum area to be covered by buildings, enclosures, containers and pools more than 20 metres from house to be limited to 10 square metres.
  7. On designated land* buildings, enclosures, containers and pools at the side of properties will require planning permission.
  8. Within the curtilage of listed buildings any outbuilding will require planning permission.

*The term "original house" means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so.

*Designated land includes national parks and the Broads, Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites.

Please Note: The permitted development allowances described here apply to houses not flats, maisonettes or other buildings. This is an introductory guide and is not a definitive source of legal information. This guidance relates to the planning regime and building regulations for England. Policy in Wales & Scotland may differ. If in doubt contact your Local Planning Authority.
