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!

Tiling- 16 Feb 2026
Luis did an excellent job on my bathroom. He had to do a lot of prep work before starting the tiling, including rebuilding the floor and repairing the walls. At every stage he explained what needed to be done, ensured that I wanted to go ahead, listed the materials that would be needed, and the cost. It made a huge different to me that Luis was willing to source and purchase all materials; he checked in with me from the suppliers as to choice and cost, and sent receipts for every penny. I cannot recommend him highly enough, for his knowledge and expertise, his honesty and hard work, and also for being such a lovely person, nothing is too much trouble. I am delighted with my new bathroom, and am planning more home improvements with Luis, when he is free again!

Extensions- 11 Jan 2018
This was our first project, and we were exceptionally fortunate to find Bujar. We're actually getting tired of hearing our family and friends tell us how lucky we are and how amazing he sounds. One of the most honest, trustworthy, and genuine people I've ever met. If I had a problem, he'd be one of the first people I'd call! In fact I did last week and he came to the rescue :) His team were all friendly, polite, conscientious and very tidy. They worked around us as much as they could, always making sure we had access to what we needed which sometimes meant it took them longer to work. Bujar is a perfectionist and is so proud of what he does, he made sure everything was done to a high standard - the estate agent who came round after we were done was impressed! His prices are very fair (better value than other quotes we got and much less time). We couldn't believe it was done in the 3 months he said it would take, and we managed to fit in a few extra bits and pieces after that. He was so helpful throughout, took all project management on and didn't bother us unless an important decision needed to be made. He drove us around all over the place to sort kitchens, bathrooms, etc. and gave us really helpful advice throughout the process. Highly recommend him and his team. I can't imagine ever wanting to look for another builder unless I had to - something that is quite common amongst Bujar's clients. We are extremely pleased with everything about our new house.

Extensions- 5 Oct 2022
I am very pleased with the work Josh and his team did in building my rear extension. They were a friendly and hard working bunch and very respectful of my space. Josh did a great job in project managing the work and making sure things were progressing as planned. Any snagging items were dealt with promptly. I would hire them again if required and recommend them to anyone who wanted to have building work done.

What experience do you have with similar extensions in West End?
