Plastering- 22 Jan 2026
I hired Aries through MyBuilder and I could not be happier with the work. He went above and beyond, even helping with tasks that were not part of his job. His workmanship is excellent, very skilled, respectful, polite, and understanding throughout the whole process. There were no hidden or extra costs, and he even worked weekends to make sure the job was completed on time. I highly recommend him and would definitely use his services again. The best expereince I've had a with a builder!

Extensions- 8 Jan 2025
Jamie is excellent guy, really quick quote, confident tradesman and did an excellent work installing some very chunky steel beams into our 200 year old, random stone house for a doorway extension. Once steels were in, expertly cut and installed the stone back into reveals. Really pleased and will consider again for future works on our precious home.

Conservatories- 14 Sep 2026
Had Bristol home improvements round to replace an old lean to conservatory. Jason came round to go through our options and then sent over a quote. We had a few more questions so he offered to come back to go through it with us again. Had excellent communication throughout the whole process. The work was completed in a week and the 2 men who done it were very polite and kept us informed of what was going on the whole time. They tidied everything up behind them and left no mess. The new conservatory looks lovely and has been completed to a very high standard. I would happily use them again in the future.

Extensions- 21 Aug 2022
Rob Workman IS a master craftsman. I know it says so in writing. But now that our extensive rebuild and extensions are complete, we have seen it with our own eyes as our project unfolded. Rob took our falling down, damp, mouldy, unattractive bungalow and gave us back the keys to what more than one visitor has described as a ‘Grand Designs’ and stunning modern home that meets the highest grade of eco builds. As well as working with meticulous care & always remeasuring twice ‘just to make sure’, Rob proved himself to be good at tackling the challenges & curve balls that doing up a house is always going to throw up. Our roof, and two of the walls, proved to be insubstantial to the point of dangerous. Rob worked hard to find a cost-effective solution which met the approval of the building inspector and structural engineers. As well as Rob working on site, he brought Matt and Josh who were the epitome of polite, careful workers whose own professionalism at everything from groundwork, brickwork roofing & much else besides was a pleasure to see. Other contractors who Rob brought in - such as Simon Stadden Windows - produced great quality work to complement that of the main team. We are than pleased with the work done, with the timeliness of the work, with the price, with the tidiness of the team, and above all with the gorgeous, solid house they have left behind for us. We can recommend Rob and his team unconditionally to those looking for builders.

Extensions- 29 Jul 2017
We are so pleased to have employed Tom Watts to build an extension (approx. 15 sq metres) off our existing kitchen and dining room. This was in order to create a large family room including a new kitchen installation. The site was not without its challenges as our house is built on a slope and required a very deep foundation to be laid. The build also required 3 RSJs (in order to remove existing walls) to create a modern space for open-plan living. Tom and his team were very easy to work with communicating any changes to the schedule and proving to be very reliable. Inevitably, as with any job such as this, there were instances where a good problem-solver was needed. Tom was able to offer creative solutions which kept the job progressing. After completing the building work T.W.Carpentry & Building also installed our new kitchen and finished the new room with new skirtings and door frames. We are very satisfied with the finished project and due to the quality of the work we are very happy to recommend this builder.
