Building a Garden Room on Listed Property Land

Within the UK, listed buildings are considered nationally important and therefore have extra legal protection within the planning system. Listing marks celebrate a building’s special architectural and historic interest. Many see owning a listed property as a privilege, however there are responsibilities that come with it.

Owners of listed buildings are tasked with preserving the charm and characteristics of their property. Due to this, building consent must be granted for home extensions or renovations that might affect a property’s historical significance.

Owners of listed properties who are looking to add extra space to their homes regularly opt for standalone garden rooms. Garden rooms are sympathetically designed to incorporate modern tastes and technologies with historical homes.


Whilst garden rooms are considered within the scope of permitted development for most properties, listed buildings can bring their own specific challenges. Any alterations made to listed buildings must be shown to both enhance and improve the original character of the property. You will require planning permission to build any structure in the curtilage of your home if you live in a listed building. This includes raising or altering ground levels, so it’s wise not to begin ground preparation until planning permission has already been granted.

Many perceive gaining planning permission to be a complicated process, but don’t be disheartened. Development rules generally apply to changes made to the building itself, and not usually to the garden. In the vast majority of cases garden rooms can be built under permitted development rights.

It’s also important to note that your permitted development rights may differ if you live in a designated conservation area or national park. This is to protect wildlife as well as the character and appearance of the countryside.

Your local planning authority will be able to talk you through any prior permissions that you will need. Alternatively, please contact our experts who will be able to advise and answer any questions you have.

If planning permission is required, don’t be disheartened as it will more than likely be granted. The latest government figures show that 87% of all planning applications are successful.


Depending on whether your property is Grade I, II* or II listed, you may need to apply for listed building consent, which is different to planning permission.

Listed building consent refers to the way in which planning authorities ensure changes to listed buildings are appropriate and sympathetic to their character.

If your listed property was built before July 1948, and your proposed garden room forms part of an extension to the property or it’s outbuildings, you may need written consent from your local planning authority before work can be carried out.

Generally, garden rooms are built separately to listed buildings and do not share any walls. This means listed building consent isn’t needed, as long as the garden building is built to the correct specifications. 

Other garden features within your property such as fences and trees may also be listed, so it’s important to check that your new garden room won’t impinge on these either.

As with planning permission, it’s highly unlikely that you’ll need to apply for listed building consent. Garden rooms are generally separate, inconspicuous buildings so prior consent is very rarely needed. 


If you’re still unsure whether you’ll need planning permission or listed building consent, do some local research. Speak to others who have had similar structures built. Neighbours with garden rooms may be able to help you better understand the local requirements and offer useful advice.

It’s also a good idea to contact your local planning authority and check with them. Building illegally could leave you facing large monetary fines.

Garden rooms built within listed property grounds must sympathetically enhance the original building’s features. This doesn’t mean your garden room needs to be constructed using ancient stone – it simply means that the materials used must not detract from your listed home’s historic character.

Many listed homes, such as old barn conversions, showcase modern materials such as aluminium, concrete and steel. Many also feature contemporary design elements such as glass walkways and balustrades. Adding a garden room will simply enhance your home’s existing charm and provide a luxurious living space for you to enjoy.


If you do require planning permission, the application process is simple and can be submitted online via the Planning Portal website. Here, you will also find a range of resources to help you gain a better understanding of the building regulations applicable to you, as well as updates on recent developments.
