Generally, garden buildings in the UK do not require planning permission. There are, however, a few exceptions to this, so it’s useful to know these depending on the intended size, placement, and purpose of your garden room.
Garden rooms are classed as outbuildings in UK planning law and, as such, fall under permitted development rights the majority of the time, and therefore, do not require planning permission. This is an advantage over other options for extending your living space as the process is quick and simple.
However, if you live in a flat or maisonette, or in a listed building, you will not have permitted development rights and will need to obtain garden room planning permission. This is also the case if you live in a conservation area, National Park, World Heritage site or area of outstanding natural beauty. If your property has been converted into a house previously, or has undergone a change or use, then it may not have the permitted development rights and would require full planning permission.
Provided that none of the above restrictions apply to your property type or location, you can usually go ahead without planning permission if your proposed garden room falls within the following criteria:
The location and size of the garden room will also need to be taken into consideration. Garden rooms cannot be placed in the front of your home, and the total area of all building on your property, including any other sheds, conservatories, garages, extensions, and other outbuildings must not cover more than 50% of the total area of your property. Please visit the Which website for more information.
Garden buildings are often used as garden offices to allow for privacy and a professional separation from home life. Most of the time, planning permission is not required as this would likely come under permitted use of an outbuilding, provided that it doesn’t change the main use of your home. However, if you are using it for more than working alone on a computer and the phone, for example holding face-to-face client meetings, or an exercise class, then you may need to ask your council for planning permission due to the potential impact on your surrounding neighbours.
Should you wish to add plumbing facilities to your garden room, you will need to check with your local council as to whether they would require you to have planning permission for this. Adding a power supply generally doesn’t require planning permission, provided that all electrical work complies with Building Regulations, specifically Part P. If these electrical works are extensive then you will have to notify your local authority building control to ensure they meet all safety regulations.

At first glance, this is just a dining extension. But in truth, it’s far more than that. Liam and Roxy’s original dining space sat awkwardly between the kitchen and snug – practical, perhaps, but never truly welcoming.
This new modular extension has transformed the way they live. It’s a room filled with light, opening onto the garden, a place where every meal feels like an occasion. The design is modern yet sympathetic, with careful choices in cladding and glazing that balance beauty, efficiency, and comfort.
It’s proof that even a modest addition, when done thoughtfully, can change the whole character of a home.

It’s a fresh perspective, a new angle to enjoy your favourite corner of the garden. A retreat beyond the four walls of your home. A space to pause, recharge, and simply be.
Or in this case… the perfect spot to sit back, savour the view of an incredible garden creation, and watch the sun dip below the horizon — fine malt in hand, peace all around.

We were back in Malton today fitting some bespoke handrails for our client. They first thought about going with glass, but decided on black iron instead—less upkeep and it looks great with the terrace!
Something oddly satisfying about watching a ground screw glide into place.
Solid foundations, set with precision.

What a week it’s been for the team at DB-Space!
At the start of the year, we set ourselves a challenge — to design and deliver a high-quality, off-site extension that could be installed in just one week. Our goal? A seamless, stress-free experience for our clients with minimal disruption to daily life.
And this week, we made it happen. Imagine leaving for work on Tuesday morning and returning home to find a beautifully crafted extension sitting in your garden — ready and waiting.
We wrapped up roof detailing on Wednesday, completed plastering on Thursday, and gave everything a final polish today. The second fix electrics will be finished on Monday, once the plaster’s fully dry.
If you`re looking to create more space without the mess and hassle of a traditional build, we’d love to chat. Drop us a message to find out how we can help bring your vision to life.

A recent installation we completed in Guisborough, North Yorkshire.
The client was in need of a dedicated trading space where he could stay focused for hours on end with the occasional break for a game of darts!
We designed this bespoke build to work with the existing landscaping scheme. The finished outcome, along with stepped access, worked seamlessly.
