Planning permission regulations were revised and relaxed in 2008,

All of our gardenrooms are under 2.5 metres in height and can be sited near a boundry. If you live in a listed building, flat , maisonette or an area of natural beauty then you will need to get intouch with your local authority.

Outbuildings are considered to be permitted development, not needing planning permission, subject to the following limits and conditions:

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 2 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 10m².

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.



If you want to put up a garden building the Building Regulations will normally not apply if the floor area of the building is no more than 15m² and contains no sleeping accommodation.

If the floor area is between 15m² and 30m², you will not normally be required to apply for building regulations approval providing that the building contains no sleeping accommodation and it is either at least 1m from any boundary or is constructed of substantially non combustible materials.
