Do you need planning permission for a garden room?

Garden rooms generally do not require planning permission because in many instances they are classed as a permitted development. Garden rooms are classed as ‘outbuildings’ and as such can be built on your property without planning permission as long as you comply with permitted development guidelines.


There are some specific exclusions so depending upon your circumstances the following should be considered when checking if you need planning permission or not:


Consideration of the size of the pod and where you intend to place the pod within your garden


  • The pod will need to be located to the rear or the side of the garden as no development is allowed to the front of the property. Outbuildings should not be closer to a road or public highway than the house itself.
  • The pod should cover no more than 50% of the garden area. Please note this will include any other extensions or garden buildings that you have already installed.
  • The pod must be single-story.
  • If the pod is to be built within 2 meters of your property boundary then it should not exceed 2.5m in height. If you want your garden room to be taller than you’ll need to apply for planning permission.
  • If the pod is to be built over 2 meters of your property boundary then a single-story garden building can have a maximum eave height of 2.5m, which is a maximum overall height of 4m for a dual-pitched roof and maximum overall height of 3m for a pent roofed building. If you want your garden room to be taller than you’ll need to apply for planning permission.
  • If your pod is up to 30 SQM (internal size) then it is exempt from building regulations. Anything bigger than 30 SQM will need to go through building regulations.


If your property is a listed building or on designated land then permitted development rights do not apply and you’ll need to apply for planning permission.


  • Designated land includes:
  • National parks and The Broads
  • Areas of Outstanding Natural Beauty
  • Conservation areas
  • World Heritage Sites
  • On designated land garden rooms to the side of the house are also not permitted development.


The final consideration will be the intended purpose of the pod


  • Permitted development is only allowed for “purposes incidental to the dwelling home” e.g. home office, hobby room, garden room, or home gym would be acceptable. However, you must not use your pod as a self-contained living accommodation and will not fall within permitted development rights.


How can you check if you need planning permission?


It is worth noting that permitted development only applies to houses – not flats, maisonettes, or other buildings. In some areas an individual property might have Article 4 directions that mean your permitted development rights have been removed.

If you have concerns or want to double if you require planning permission for your project then we recommend checking with your local planning authority.


For added peace of mind and if your situation is not clear and you have concerns you can apply for a lawful development certificate (an LDC is chargeable). This could be helpful when selling your house or if your neighbours have any concerns.
