    Do You Need Planning Permission For A Garden Room?

    The perfect living space could be closer than you think...

Garden Rooms - Planning Permission

Garden Rooms benefit from relaxed building regulations and fall into the permitted development category...

New regulations brought into effect on 1st October 2008, state that garden rooms do not require planning permission and are in fact covered under permitted development. As always, permitted development is subject to limitations as follows:

Building Regulations - What You Need To Know

  • No outbuilding on land forward of a wall forming the principal elevation.
  • Outbuildings and garages to be single storey with a maximum eaves height of 2.5m and a maximum overall height of 4m, with a dual pitched roof or 3m for any other roof.
  • Maximum height of 2.5m in the case of a building, enclosure or container within 2m 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” (the term original house means as it was first built on 1st July 1948) would be covered by additional or other buildings.
  • In Areas of Outstanding Natural Beauty, the maximum area to be covered by buildings, enclosures, containers and pools more than 20m from house to be limited to 10sqm.
  • On designated land (inc Areas of Outstanding Natural Beauty/conservation areas), buildings, enclosures, containers and pools at the side of the properties will require planning permission.
  • Within the curtilage of listed buildings, any outbuilding will require planning permission.


Permitted development allowances described above apply to houses, not flats, maisonettes or other buildings. Be sure to check with your Local Planning Authority whether permitted development rights apply as they may have been removed. Additional consents may be required if your property is listed or in a designated area.

Expert Tip - Extra Light

"Garden rooms featuring a pitched roof not only look amazing but also offer the opportunity to install high level glazing - a glazed gable will flood the room with nautral light and can be combined with glazed doors to further improve lighting levels."
