PLANNING CLINIC
Sheds, summerhouses, greenhouses, pergolas — they can all potentially trigger the need for planning. Here’s everything you need to know to avoid a costly dispute with your local council
When it comes to home renovations, most of us know that certain changes will require planning permission from our local council. However, it may come as a surprise to many that even garden structures such as sheds, summerhouses, and pergolas can also trigger the need for a planning application. So let’s explore everything you need to know about planning permission for garden structures and how to make sure you stay on the right side of the law.
SHEDS, GREENHOUSES AND SUMMERHOUSES
Under the rules for permitted development, garden structures such as sheds, greenhouses and summerhouses are usually allowed without the need for planning permission — as long as they meet certain criteria. These criteria include:
● The structure must not take up more than 50% of the total area of land around the original house.
● The structure must be singlestorey with a maximum eaves height of 2.5m and a maximum overall height of 4m for a dual-pitched roof, or 3m for any other roof type.
● The structure must not be used for sleeping accommodation.
● The structure must not be within the grounds of a listed building.
However, it’s worth noting that some areas – such as conservation areas, National Parks, and areas of outstanding natural beauty – may have additional restrictions on what is allowed under permitted development rights. It’s always best to check with a professional planning consultant to make sure you’re not breaking any rules.
PERGOLAS, GATES, FENCES AND WALLS
Like sheds and summerhouses, pergolas (arched framework structures) are also usually allowed under permitted development rights, providing that they meet certain specific criteria.
designated area. Again, check with your local council or a planning consultant to make sure you’re not about to break any rules.
ADDITIONAL ELEMENTS
Other garden elements that may require planning permission include decking and paved areas. In most cases, decking and paved areas are allowed under permitted development rights, as long as they meet certain criteria. These include:
● The decking or paved area must not take up more than 50% of the total area of land around the original house.
● The decking or paved area must not be more than 30cm above ground level.
● The decking or paved area must not be in a conservation area or other designated area.
