The Cousins guide to planning permission for garden buildings
Planning permission for garden buildings
Do I require planning permission for a garden building?
This is a very common question we get asked more or less every week. This guide to garden building planning permission covers all types of garden buildings including garden sheds, summerhouses, garden studios or garden rooms, greenhouses, workshops and concrete garages.
In short, most garden building installations do not require planning permission as they are deemed to be “permitted development” as long as you follow the very simple guidelines as listed below.
For the very latest information on planning permission visit the government planning portal website.
Follow these simple guidelines and you wont need planning permission
Do not build your garden building on land that is forward of the principal elevation. IE: Not in your front garden.
Your garden building is of single story construction with a maximum eaves height of 2.5 metres (2500mm) and a maximum overall height of 4 metres (4000mm) for a duel pitched roof, or 3 metres (3000) in any other case.
Your garden building has a maximum height of no than 2.5 metres (2500mm) if situated within two metres (2000mm) of a boundary.
Your garden building does not have a veranda or balcony.
Raised platforms such as decking are allowed as long as it is no higher than 300mm.
Your garden building does not exceed anymore than 50% of the total area of land around the original house* which should include all other existing buildings. All outbuildings and even extensions to the original house must be included when calculating the 50% limit, even if the extension was built prior to your occupancy.
*The term “original house” means the house as it was first built or as it stood on 1st July 1948 (if it was built before that date).
However, there are some instances where planning permission is required and its important to take note.
You will require planning permission if your garden building is to built on a property that resides on designated land. IE: Designated land includes national parks and the Broads, areas of outstanding natural beauty, conservation areas and world heritage sites.
Its also worth noting that if your property is in a National Park, the Broads, an area of outstanding Natural Beauty or world heritage site the maximum area that is allowed to be covered by garden buildings, enclosures, containers and pools more than 20 metres from house to be limited to 10 square metres.
