Kitchen Fitting- 17 Nov 2025
We recently had our kitchen refurbished by Dumitru, and we couldn’t be happier with how everything turned out. He’s one of those rare builders who combines professionalism with real care for the details. He worked efficiently, kept the place tidy throughout the project, and always cleaned up after himself — which honestly made such a difference when living through a renovation. What I appreciated most was how supportive he was when it came to choosing the right materials. He guided us through the options without ever pushing, and his advice proved spot-on. The final result is exactly what we hoped for and more. If you’re looking for someone reliable, skilled, and easy to work with, I totally recommend Dumitru P.S. For anyone curious about the scope of the work: Dumitru changed our worktop, removed the old tiles and redid the flooring with laminate, installed a new cooker and hob, fitted a new sink, repaired the walls after the new boiler went in, and repainted everything. Top work

Ahmad and the Beam Developers team did an amazing job on my rear extension. We were very particular with our requests and are generally picky people but they were very patient and accommodating to our every request. We were shown the drawings, made adjustments and managed to tailor the project exactly to what we wanted. The finished results were amazing. No big project for us soon but should we plan to do the loft will definitely use Ahmad and his team again.
