"JMB’s unofficial motto is “it’s all in the details” and it couldn’t be more accurate…from steel girders to mastic to the tiniest bit of grout between tiles, no detail is left ignored. The builders themselves were all lovely and a pleasure to see every morning. I’ll actually miss them now that it’s over. I would have no hesitation in recommending JMB for any work needed, I’ve not even been asked or prompted by JMB in anyway whatsoever to even write this review, this is all a genuine account of the entire project. JMB – not 5 stars, but the coveted 6th! It’s been a pleasure!"

"JMB Design and Build are the most trustworthy people in this area. I had a house extension done. They responded to my queries promptly, completed the project within the budget (including minor additions to the scope of works) and in a very reasonable timeframe. The workers treated my house and family with at most respect. We continued to live in the liveable area and work itself progressed without any disruption. I carried the design via an external architect. In the hindsight I will most definitely request the design from JMB’s firm directly. Since they took care of all the inspections required"
