Garden Room Permitted Development
An Outdoor Room Without Seeking Planning Permission!
In the majority of cases you are allowed to have a garden room built in your property's outside space without seeking planning permission.
All our garden rooms have been specifically designed to meet the requirements of the current permitted development rules and building regulation requirements.
Permitted Development Guidelines
Outbuildings are considered to be permitted development, not needing planning permission, subject to the following limits and conditions detailed below:
- No outbuilding on land forward of a wall forming the principal elevation.
- 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.
- 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.
- No verandas, balconies or raised platforms.
- No more than half the area of land around the "original house"* would be covered by additions or other buildings.
- 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.
- On designated land* buildings, enclosures, containers and pools at the side of properties will require planning permission.
- 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.
