Extensions- 7 Mar 2026
Viktor is an excellent builder. He understands the needs of a complex job and mine was a huge renovation project. A side return and extension and full refurbishment of the house including the installation of 3 bathrooms, Kitchen, cupboards and much much more. It’s not quite finished yet but the house is transformed and the work was done incredibly fast, far faster than I had anticipated. I moved out for the duration but I was back in the house within 4 months. The language barrier made things a little harder than they might have been but we got by. If you have someone to project manage the job alongside Viktor I would suggest that but if you want someone who is really very good at his trade and runs a tight team I would recommend Mhilli Construction for your job.

I hired Nikolay and his coworker to build a small walk in closet. The job was done properly and they delivered what was promised in the estimated time. They also left the house tiny and clean. It was a nice experience. The price was also really good.

Loft Conversion- 20 Jan 2023
Really lucky to find Rahman as our choice of builder. Communication and quality of work was second to none all done for a fair price. Any issues or delays he was expecting he communicate to me as soon as he knew. His team were great, all professionals and cleaned up after each day of work was complete. Highly recommended and look forward to working with him again on my future projects.

Extensions- 5 Sep 2019
One of the best builders I have ever worked with. PMB take great pride in the work they do and finish to a exceptional level (even better than a lot of premium and expensive builders in the industry). Colin's knowledge about all aspects of building work is unmatched and that shows in the end product that he and his team delivered for me. PMB did a full refurbishment & substantial extension (everything knocked down except 3 external walls) - ground floor ext, first floor ext, loft extension, full re-wire, plumbing, gas, UFH, walls, plastering, fitting, decorating etc. His prices are reasonable and he advised when unexpected costs come up so I could make a decision on what to do. I will definitely use him again.

Decking- 29 May 2020
Started on time and completed the decking extension & renovation to a high standard. Ensured that small details like cuts around poles etc, were finished properly and not left with gaps. Next time I would confirm that clearing rubbish is part of the quote, but highly recommend Przemek for quality finish.

Conversions - General- 3 Apr 2026
I originally left Stuart a five star review because the workmanship and communication were excellent, and I booked him to return to complete the internal works on our extension. After paying a deposit, the work was due to start on 27 June, but Stuart never turned up and stopped communicating. His partner later asked if I could delay the work for a few months because he couldn't contact me. When I explained I couldn't wait and politely requested my deposit back, I was blocked. I have now been left with no option but to take him to the Small Claims Court to recover my money. It's a real shame because the original work was of a high standard, but I cannot recommend someone who takes a deposit, fails to return, and then ignores all communication.

Extensions- 10 Apr 2021
Although I posted for a kitchen extension quote I decided that I would proceed with this at a later date. I did have a lot of other building work such as chimney removal that was undertaken by A2Z Property Improvement Limited. I am happy with the the work that was carried out. I'll certainly be reaching out to A2Z again for the extension once I'm ready to proceed. I would definitely recommend this company.

What experience do you have with similar extensions in Clapton?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Clapton extension builder’s ability to deliver a result that meets your expectations.
