Garden Room Planning Permission - Terms & Conditions
Listed below are the garden room planning permission rules and whether you need permission for your dream garden room, office or log cabin.
- On designated land, outbuildings to the side of the house are not permitted. Designated land, in this case, refers to areas deemed as Areas of Outstanding Natural Beauty (AONBs). AONBs typically include national parks, B roads (numbered distributor roads), conservation areas, and World Heritage sites.
- Outbuildings are not permitted on the grounds of a listed building. Listed buildings are structures that hold some degree of historical or architectural importance.
- In national parks, B roads, AONBs, and World Heritage sites, the total area covered by any outbuildings more than 20 metres from any wall of the house must not exceed 10 square metres. Otherwise, the build will not qualify as permitted development.
- The build of an outbuilding is not permitted if the building is forward of the principal elevation of the original house. The original house is the house as it was first built, and the principal elevation is the front of the house that generally faces the road.
- Outbuildings and other additions must not surpass 50% of the total area surrounding the original house. All other outbuildings and extensions, such as sheds, must be accounted for when calculating the 50% limit.
- To qualify as permitted development, an outbuilding must not be a self-contained living accommodation or have its own microwave antenna.
- Outbuildings must be single-storey and not surpass the maximum eaves height of 2.5 metres. The overall height of the building must not surpass 3 metres. If the building has a dual pitched roof, however, its overall height must not surpass 4 metres.
- If within 2 metres of the property boundary, the entirety of the outbuilding must not surpass 2.5 metres in height.
The permitted development allowances detailed above apply exclusively to houses. The construction of outbuildings and extensions onto flats, maisonettes, and other buildings come with different sets of rules and regulations. Contacting your Local Planning Authority may be necessary to ensure that permitted development rights to your property and the planned build.
Please note, other consents with regards to garden room planning permission may be required if your house is considered a listed building or if it is on designated land, as described above.
