Do You Need Planning Approval For a Shed?
Sheds come in all shapes and sizes. You could have a handy storage space for the gardening equipment, a sizeable agricultural building, or a big industrial unit. And perhaps that's where some of the confusion about planning permission can arise. Because 'shed' is such a wide-ranging term, there's no one-size-fits-all response to the question, 'Do you need planning permission for a shed?' This article aims to cut through the confusion and point you in the right direction, and for ease we'll categorise sheds as residential, agricultural and industrial. But first, let's take a look at permitted development rights.
Permitted Development Rights For Sheds
For householders, permitted development rights (PDR) allow improvements or extensions to be completed without planning permission, if the application process would be out of proportion with the impact of the works carried out. So, if you're planning on adding a lean-to you can go ahead, but if you're adding a two-storey brick-built extension, you need to apply for planning permission.
When it comes to commercial developments, PDR may still apply. There are conditions and limitations attached with regard to, for example, the size of the intended building in terms of both floorspace and height, and also location. Areas of land subject to exclusion from PDR include National Parks, conservation areas and Areas of Outstanding Natural Beauty.
Planning Permission For Residential Sheds
If the shed you want to erect is an outbuilding in the garden of your house – and this includes greenhouses – you don't need planning permission. Be sure to check that your intended building comes under the category of 'outbuildings' and conforms to the rules laid down for them, and bear in mind this only applies to a residential dwelling with its own land attached. If you want to know more, this is a good place to start.
Planning Permission For Agricultural Sheds
PDR applies to certain types of shed – and other agricultural buildings and works – but is subject to a range of issues. They include the size of the farm (5 hectares or more), the size of the shed (no more than 1,000 square metres), how close to a road it is, what the usage will be, whether dwellings are present on the site, and even whether it's near to an aerodrome (height restrictions will apply).
It's always best to take advice from people with specialist knowledge, including your local planning authority.
Planning Permission For Industrial Sheds
Subject to certain conditions, an industrial shed can come under the umbrella of PDR. To qualify, the floorspace must be less than 200 square metres – or 100, if it's on designated land or a site of special scientific interest. As to height, it depends how near to the site boundary the building will be. If it's within 10 metres, then the maximum height allowed is 5 metres. If it's more than 10 metres from the boundary, then a new building can't be taller than either 15 metres or the existing highest building, whichever is the lower. You might see the term 'curtilage' being used; it just means the area of land surrounding the existing building(s).
It's a good idea to seek expert advice and/or check with your local planning authority before going ahead with anything.
