Extensions- 14 Jul 2021
Juro and his team completed a total refurbishment of our house that included removing all internal walls, along with a double story side extension, a huge job involving lots of steels, re-roofing, new construction, new bathrooms and kitchen, new windows and rendering along with all the plumbing and electrical work and decoration. They did the most incredible job, working efficiently, adapting to any problems that came along and working really hard to create the best finish possible at the budget we had. Despite the pandemic arriving just after the demolition stage, they didn’t miss a day on site, and worked tirelessly to get materials to keep the project moving. Incredibly they still managed to finish the project on schedule and to a standard that was exceptional. Juro is honest and upfront, didn’t ever add costs or ‘unforeseeables’ and was an absolute joy to work with. He also stuck to a very clear payment schedule that was easy to follow and always meant we only paid when we were absolutely 100% happy. My only reservation in writing this review is that I would like to selfishly hang on to him and keep his schedule clear for future jobs with family and friends!

Conversions - General- 25 Nov 2025
Outstanding work by Paul, Pano and the team. This was a big renovation job and inside and out, the workmanship and dedication was second to none. The project took a while to complete but there was much more to done than originally planned and I asked for additional work to be completed. The communication was very good, Paul and Pano made suggestions for additional improvements and how to overcome problems. Nothing was too much trouble and everything was taken on with enthusiasm and great commitment. Even Melanie from the office was very efficient with her communication regarding payments and invoicing. I am delighted with the outcome and would highly recommend TRB to anyone looking for building or renovation work. TRB is a very professional firm, well organised and with a good eye for detail, all of which were very important throughout the project. Great work TRB!

Bricklaying- 1 May 2019
Chris repaired and made a new pillar for my front garden wall and fitted a rail to match an existing one. I asked him if he could also replace a garden border and fix a chain across my front patio. All jobs were completed to a high standard, and he even returned with a special attachment to make fastening the chain easier. I was impressed by his workmanship, versatility and thoughtfulness and shall certainly be using Chris again.

Great work by Luke and all his team. The work is to a really high standard and aesthetically pleasing. Luke's attention to detail is second to none. His brickwork is amazing. He listens to any questions or concerns and makes sure that he answers and resolves them. The finished product is way beyond what we had expected. The site was managed well and all members of the team were respectful and they worked well together. I would certainly recommend Luke for any building work you need doing as he makes sure that the job is done well and stress-free.
