Getting planning permission for garden buildings is straightforward and we undertake it for you.
Permitted development allows you to build ‘incidental structures such as sheds and summerhouses without Planning Permission. With garden rooms or a garden office much depends on how you intend to use them.
Planning permission for garden offices
An office used as an home study combined with other leisure uses may not need Planning Permission if it meets other permitted development criteria. We explain permitted development rules and how they relate specifically to garden offices in greater detail on our blog. Visit garden office planning permission for more information.
Planning permission for garden rooms
A garden room used for occasional or ‘incidental’ leisure use such as a studio or gym that meets permitted development requirements shouldn’t need Planning Permission. But, it’s vital to double check with your planning department and we will do this for you.

You’ll always and without exception need Planning Permission.
What is Permitted Development?
Permitted development is building work that you can do to your home without needing planning permission. Only garden rooms or studios that have an “incidental” use can be built without planning permission. Incidental use can be loosely defined as things you don’t do in your main house. Hobbies are often viewed as incidental use, as are storage, gym and other occasional uses and even then, the building has to meet various constraints re size and position.
If your building has an “ancillary” use it may need planning permission. Ancillary uses are such things as sleeping, showering. I.e. Things that you can also do in your house.
What does “incidental” mean?
The meaning of “incidental” in planning permission legislation has never been accurately defined. Traditionally an “incidental” building is a garden shed, summer house or a greenhouse – a building that you will use ocasionally to perform tasks that you can’t perform in your house.
If you build a general purpose garden room that you may sometimes use as a home office, most local authority planning departments will view this as “incidental”, but some won’t. This is why we invite consult us at an early stage about Planning Permission for your garden building. Tel 01524 737999.
How do I find out if my garden office or garden room is “incidental” and if it will need planning permission?
- Read the Permitted Development guidelines below
- Have a conversation with us about all aspects of planning permission
- Consult your local council’s planning department.
A garden office or garden room that contain plumbing
In our experience, a garden office or garden room that contains plumbing will need planning permission, though some local authorities may be happy with a Certificate of Lawful Development.
Permitted development guidelines – England and Wales
View guidance for Scotland.
Garden rooms and studios are considered to be permitted development, not needing planning permission, if they meet the following requirements:
- No garden building built on land forward of a wall forming the principal elevation of the main house.
- Outbuildings should be single storey with a maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof.
- A garden room must have a maximum height of 2.5 metres if it is built within two metres of the garden boundary.
- No verandas, balconies or raised platforms – including decking of more than 300mm high..
- 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 that are more than 20 metres from house must be limited to 10 square metres.
- On designated land* garden buildings 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.
Permitted development guidelines – Scotland
Permitted development rights in Scotland allow for the provision of any building required for a purpose incidental to the enjoyment of the dwellinghouse. Typical developments include sheds, garages, sun-houses and greenhouses. In summary, the effect of the limitations is that:
- Ancillary buildings are generally located to the rear.
- At least half the curtilage remains undeveloped.
- The height of the building is not higher than 4 metres and the sections within 1 metre of the boundary would not be higher than 2.5 metres.
- The height of the eaves is not higher than 3 metres.
In the case of dwellinghouses in aconservation area or within the curtilage ofa listed building development is permitted developmen t as long as the footprint of the ancillary building does not exceed 4 square metres. Listed building consent is required if the proposed development affects the character or setting of a listed building.

Running a business from home
Sometimes you need planning permission to run a business from home – regardless of whereabouts in the home you work. The key test is whether the overall character of the dwelling will change as a result of the business.
If the answer to any of the following questions is ‘yes’, then permission will probably be needed:
- Will your home no longer be used mainly as a private home?
- Will your business result in a noticable rise in traffic or people calling?
- Will your business involve any activities that are unusual in a residential area?
- Will your business disturb your neighbours at unreasonable hours or create other forms of nuisance such as noise or smells?
Whatever business you carry out from your home, whether it involves using part of it as a bed-sit or for ‘bed and breakfast’ accommodation, using a room as your personal office, providing a childminding service, for hairdressing, dressmaking or music teaching, or using buildings in the garden for repairing cars or storing goods connected with a business – the key test is: is it still mainly a home or has it become business premises?
If you are in doubt you may apply to your council for a Certificate of Lawful Use for the proposed activity, to confirm it is not a change of use and still the lawful use.
Do I need planning permission for my garden office building?
If you can answer no to the above questions you probably don’t need planning permission to run your business from home, but you may still need planning permission to build your garden office. Talk to us about this on 01524 737999.
What are Building Regulations?
Planning permission and Building Regulations are not the same thing: -
Building regulations govern the quality and technical design of a structure. The fire proofing, the structural integrity, the amount of insulation, the solidity of the foundations.
Planning permission governs the relationship of a building to its surroundings. The position, external appearance and size of the structure.
Our buildings are designed and built to the same construction standards as a new house that you would choose to live in all year round – detached extensions will be usde for many years to come. We voluntarily choose to meet building regulation standards of construction for all our buildings, even if they are smaller than the regulations requirements. We believe that any lesser standard of design, insulation, construction and foundations is inadequate for an outdoor room that is used as an all-year-round living or working space.
Will my garden room or garden office have to meet Building Regulations?
A garden office or garden room with less than 15 sq metres of internal floor space does not have to meet building regulations unless it is used as sleeping accomodation.
A Building with less than 30sq metres of internal floor space, if it is positioned more than a metre from the garden boundaries does not need to meet building regulations unless it will be used as sleeping accomodation.
The above rules mean that some unscrupulous companies that sell insulated summerhouses and sheds of less than 30sq metres claim that their buildings ‘meet building regulations.’ What they really mean is ‘our buildings don’t have to comply with building regulations’.
Will my garden guest room have to meet Building Regulations?
Yes, if it is built specifically for use as a bedroom it must meet building regulations. Whatever the size of the building.
Will my granny annexe have to meet Building Regulations?
Yes, if it is built specifically for use as living/sleeping accomodation it must meet building regulations.
Who will make my building regulations application?
We will make your application for you, if you need one. We have all the technical and structural details necessary to make the application.
