Extensions- 3 Oct 2022
The Guys were great, excellent work, put the hours in to get the job done, 99% of the work is done they're just coming back to install the windows once they've been manufactured. But the rest of the work, I can't fault it having had a terrible experience whilst building the house a few years ago these guys went above and beyond, and proved there are good builders around. Great attention to detail and skilled. Would happily recommend them and use them again on future building projects.

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.
