Latest review:
Florin extended and completely refurbished our 4-bedroom semi-detached house. This included extensive steelwork, underfloor heating, complete re-plumbing and rewiring, excavation, and an entirely new slate roof as well as varying extensions up to three floors high. I cannot say enough good things about his workmanship, professionalism and reliability. His workmanship makes a perfectionist like myself happy. He is also completely professional: even with our difficult neighbours he was always courteous and understanding, and even helped them sort out issues at a moment’s notice that had nothing to do with his building work on our property. And he is also thoroughly reliable. I cannot think of any instance where he committed to something and did not deliver — he even managed to finish all the work on our house ahead of schedule and on budget. We have been so happy with his work that we contracted him to build us a summer house as well, from scratch, and to complete revamping our front garden including elements of hard landscaping. Again he delivered flawlessly and we are very happy with the result. We also continually receive positive comments from people passing by and just seeing the front garden. We have used several other builders in the past on other properties, including far more expensive ones, and none compare to his level of competence, attention to detail in his workmanship, his complete professionalism and thorough reliability. Now that we have found Florin, we will never look for another builder again. I just hope once others experience what he delivers for themselves he will still have some availability for us in the future!

Extensions- 25 Aug 2021
Having had bad experiences in the past with other builders, this time we tried to do our homework properly before hiring someone. We couldn't have chosen a more competent and professional builder! We obviously asked around and had many quotes (some ridiculously expensive, others didn't even seem to understand what we wanted to do) but Sorin immediately impressed me with his detailed and fair quote, knowledge and lots of suggestions (he's the kind of guy that immediately gives you the impression that he knows what he's talking about). We encountered some issues during the works (which is to be expected if you didn't build the place yourself) but Sorin and his team did an amazing job and always gave us regular updates. End result? Work completed on time and a new construction that is exactly what we asked for (plus other things here and there that he kindly sorted while he was on site!)

HEXAFORM CONSTRUCTION LIMITED
Rating: 5 out of 5
Extension Builder in Wembley
HEXAFORM is a London based multi-disciplinary design and build company that has the experience, work ethic, communication tools, and systems in place needed to bring any scale project from a virtual blueprint to reality. Historically the architect-contractor relationship has been one of an ‘us versus them’ mentality. But we’re 'both'. Having a design team under the same roof as a construction company means that the eccentricities of each project are rendered opportunities, rather than obstacles.
