A garden room is one of the most effective ways to add valuable, flexible space to your home without moving. Whether you need a quiet home office, private gym, creative studio, therapy space or somewhere to entertain, we will design the room around your property, lifestyle and budget.

Based in North Somerset, we build premium garden rooms across North Somerset, Somerset, Bristol and the surrounding areas. Every project is individually planned, using quality materials and construction methods designed to provide strength, longevity and year-round comfort.

In many cases, garden rooms fall under permitted development, meaning planning permission is not required. Every property is different, so we will discuss the likely requirements during your consultation and help you understand what applies to your project.

“Jordan is very good at what he does. Kept us informed throughout the whole process and helped us with decisions even if it meant more work for himself. He sets himself a high standard which he 100% delivers to. I would recommend Jordan to anyone and everyone!”

Joe HanceGoogle
“I’ve used jordan at JB Carpentry on a number of occasions over the last 3 years and the quality of his workmanship is second to none. Whether it was hanging new internal doors, laying solid wood flooring or building a bespoke wooden bath panel, everything was done with a level of skill and precision that I’ve not encountered previously with any other carpenter. He always ensures the site is left clean and tidy and is really warm and friendly which takes away the stress which can sometime occur when someone is working in your home. Simply put I wouldn’t go anywhere else for carpentry work.”
