Great Garden Rooms
What customers say
What homeowners most often single out about this Portsmouth-based garden room builder is the professionalism and consistency of Craig and his small team, whether working alone, alongside his son Rhys, or with colleague Jack. Communication throughout a project is a point that comes up often, with customers describing steady updates on progress, contractor visits and any issues that arose, all clearly explained and quickly resolved. Cleanliness on site is another point repeated across several accounts, with reviewers noting that the work area was left tidy after every visit, regardless of weather conditions. The range of projects described includes garden offices, a studio for glasswork and pottery, patios, decking, levelling and turfing, and a SIP panel extension finished with brick slips, a Velux window, and bifold and French doors. Several customers mention that quotes were itemised in full with no unexpected costs appearing later, and more than one reviewer returned to commission further work after an initial successful project. Difficult site conditions, including restricted vehicle access along a footpath, are described as having been managed calmly and efficiently. Timescales are described as swift, with one build finished inside three weeks. The consistent thread across the feedback is a team that listens carefully to a brief and produces a finish that matches or exceeds what was originally envisaged.

Fabulous garden room built for us by Craig and his son, Rhys -(a father and son team who worked seamlessly together). They worked hard through challenging weather and always kept me up to date with how things were progressing. Any issues that came up were fully explained and swiftly sorted. Looking forward to quality time in this great new space, which will look even better when I am able to soften the look with some planting should it ever rain. Thank you, Craig.
We had an awkward space that needed a completely bespoke garden room, and the team absolutely nailed it. They were easy to work with from start to finish, listened to every idea, and brought my vision to life perfectly. The craftsmanship and attention to detail are fantastic, and I couldn’t be happier with the finished result. I wouldn’t hesitate to recommend them to anyone looking for a high-quality, bespoke build. Thank you!
Craig and his team supplied and installed our garden room within a matter of weeks nothing was ever a problem during the build very happy with the outcome and would highly recommend his services
An absolutely brilliant service from Craig and the team. From the day of his initial visit to the run up to the build, right through until the end we have been very well looked after. We have had a 5m x 5m Garden Room built and it has exceeded our expectations in terms of building quality. Our initial quote was roughly what we expected, and Craig stuck to budget despite there being a 6 month lead time. The extras we agreed through the build were clearly itemised and reasonably priced. Throughout the build communication was clear, and we were consulted whenever there was a small issue or variation on the original plan (for example our decking changed shape). Craig's attention to detail lasted right until the final day, and he has delivered a first rate product. We would highly recommend Great Garden Rooms.
Craig built a small garden room for me complete with sedum green roof. I have been using it daily for a couple of months now and I cannot fault it. Craig and his team were very professional, polite and tidy. Even the weather did not stop them working. I highly recommend them for you building project.
Craig and his team have done a fantastic job restoring and rebuilding our garden room (better described as a small extension). Craig’s attention to detail is exceptional. Watching him carefully inspect the work, identifying and correcting even the smallest imperfections, showed us that he is truly experienced and takes great pride in his craft. He was always polite, respectful, and considerate when interacting with our family (and our pets!). We really appreciated how he took the time to explain each stage of the build, provide updates on progress, and give realistic completion estimates. At the end of each day, he would also spend extra time ensuring the area was clean and tidy, which made a huge difference in keeping our home comfortable during the work. In fact, the only thing we got wrong was his coffee — Craig takes milk! (He must have had ten cups of black coffee before politely mentioning it!) We are genuinely grateful for the quality of work Craig has delivered and having him in our home has been a pleasure. We would recommend him without hesitation.
What a fantastic experience our garden project was. Not only a garden build but also extension of patio and the whole garden levelled and turfed. Craig and Jack were both brilliant. Kept us in the loop the whole time, made sure we knew when contractors were coming and the build was incredibly quick. Well worth it in every way!!!!
