   Our home extension with Gary turned into an endless disaster. It took twice as long to complete as promised and further costs were gradually added without any transparency. Sub-contractors were brought in but they eventually stopped working because they didn't get paid.

   We are delighted that we chose GB Build Ltd to complete our kitchen extension in 2025. From start to finish, Garry and his team were professional, approachable, and highly attentive to detail. They managed the five-month project efficiently, keeping us informed at every stage and ensuring the process was as smooth and stress-free as possible. The tradespeople he brought in were equally professional, tidy, polite, and always arrived when they said they would. We couldn’t be happier with the quality of the work and the end result. We would not hesitate to recommend GB Build Ltd and will certainly turn to them for any future projects.

   Home extension in Baldock. From the start of our single storey extension Garry put us in touch with an architect. He provided ideas with the design to meet our family needs and helped us with a solution for adjoining to our neighbours existing extension. The site was kept neat and tidy. The team was polite and courteous to us and our neighbours. He managed the project, supplying plumbers, electricians and a glacier. His younger team members Paul & Josh were very efficient and helpful. Work was completed to a high standard and we are really pleased with our new extension.

   We used Garry for our refurb in the spring of 2018. The quality of the work is excellent and Garry will talk you through all aspects of the work and fully explain why they are doing what they are. The important thing in addition to the quality of the finish is the unseen bits. We had steels put up at the rear and the middle of the property; when NHDC Building Control arrived the inspector spent about 3 minutes on site. When I said it was a quick visit her response was "that's because it's been done properly". Garry can also recommend architects and structural engineers so if you need a big project I recommend the company wholeheartedly!

   Garry and his team are a considerate and understanding contractor that can organise the build with minimum disruption.
