planning permission for a shed

It is a question plenty of DIY or home-improvement enthusiasts ask themselves before getting too carried away buying new materials or starting any construction work: Do I need planning permission for a shed? Well, that isn’t as simple a question as you might think, and actually relies on a number of different factors that come into play when choosing the right shed for your garden.

Under current UK laws (c. 2016) most sheds are classed as ‘permitted developments’ by most local authorities, meaning that – generally speaking – you won’t need planning permission for a shed. But how big can a shed be without planning permission? And does it depend on where it is built, or what it’s made of? Well, to help you get to grips with the law we have sourced nearly all of the rules and guidelines on planning permission for a shed in England and Wales – just be sure to check with your local council as well, and these should put you on the right track.

Garden Shed Planning Permission

Under most local authorities, you won’t require planning permission for garden sheds so long as the new build fulfills the following criteria:

  • The shed is mostly wooden, or wood-based.
  • It covers no more than half of the overall garden space, and is at no point less than one metre from a boundary wall.
  • The shed has a floor area of no more than fifteen metres squared, and a maximum eaves height of 2.5 metres.
  • The shed doesn’t face a road or motorway.
  • The shed has a veranda no higher than 30cm at ground level.
  • If the shed is made of wood (i.e. a combustible material), it is erected at least two metres away from any point of the main property.

On the other hand, you will require planning permission for a shed if…

  • The shed is being used as alternative sleeping accommodation.
  • The shed takes up more than 50% of your total garden space (incl. side alleys and any parallel driveways).
  • You install a toilet inside the shed itself.
  • The shed is doubling up as your business premises (i.e. rather than simply a home office or study space).
  • The new build is in a conservation area or National Park, built on a listed property, or if you are building a new shed in a designated Area of Outstanding Natural Beauty.

Remember, building a new shed that stays within all these rules can be a tricky business – so it is always a good idea to have a professional on board during at least some stage of the construction process. A quantity surveyor, project manager or architect will be able to help you formulate the right blueprints for your new shed to ensure you aren’t in breach of any Building Regulations – so you won’t have to worry about obtaining any retrospective planning permission further down the line.
