Something we are often asked is, ‘will I require planning permission’… The answer is no, it is not usually required as our garden rooms comply with permitted development laws. Planning differs if you live in a listed building, or conservation area. We are happy to clarify any uncertainty and answer any questions you may have.


Built with FSC-sourced timber, woven into the structure are insulated Celotex panels in the floor, roof and walls. Garden rooms that are correctly installed with Celotex insulation will make substantial energy savings over time compared to conventional garden buildings.

Our clients use their garden studios for a variety of purposes. For instance; art studio, or snooker room in which to enjoy your hobby, a home gym to workout in private or a garden office to reduce the daily commute. In fact, a garden studio can be a fantastic blend of both indoors and outdoors.

Above all, we would love to discuss your ideas to see how we can help with your garden studio.
