Our Testimonials
Had a great experience with Build Team as complete renovation novices. We liked the structured Build Team payment system with transparent costings. We would use again without hesitation if needed.
Build Team did our house top to bottom, and were very professional throughout. Our build manager was always organised and on top of things. A lot of things I wanted were not easy and they managed to deliver a really high end product.
I couldn't be more pleased with the work carried out by Build Team. From start to finish, Dan, Mark and the team ensured that we were kept informed of what was going to happen and when, so I could organise my family around the works. I would say Build Team made it as easy and hassle-free as humanly possible. We're so pleased with our new extension.
Having endured the problems of having major works carried out on our house in the form of a loft extension, I was aware of the pitfalls of incurring a poor builder. I was very fortunate to have Build Team as they were professional all throughout the build. It was a truly wonderful experience (something I never thought I would ever say about a major build).
We used Build Team for the design, planning and construction of our side return extension. We fully recommend them. Having done numerous projects this was by far the easiest and most stress-free (especially as we lived in the house whilst the works were happening). Both the build manager and main builder were exceptional, and dealt with any problems or changes efficiently.
