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.

Architecture- 6 Sep 2018
Vishal did an excellent job with our extension drawings by incorporating all our requirements and also suggesting changes which added more value to our proposed extension. Submitted the planning permission on our behalf and was really helpful. Vishal was happy to do multiple drawings for us until we were happy with outcome all in the initial agreed fee. I would highly recommend Vishal.

Extensions- 6 Aug 2022
Majid has been great in producing drawings for our rear extension. He's also helped explain the whole build process to us from design, building inspection, and building. We received our drawings in under 10 days from the initial consultation and site visit. Majid was accomodating and was able to visit the site on weekends for the initial consultation. Always a pleasure to deal with and has been easy to reach over the phone or email. Would highly recommend Maji and MYD Studio London to anyone looking for an architect.

Kenny and team did a brilliant job replacing my old lean-to porch area for a new smart extension with windows, door and even a cat flap. They were on time, organised, efficient and took away all the old materials and rubbish. Kenny was helpful when he visited and prompt in replying to all communications and supplying quotes and invoices. I am very happy with their work and wouldn't hesitate to recommend their services.

What experience do you have with similar extensions in Knightsbridge?

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 Knightsbridge extension builder’s ability to deliver a result that meets your expectations.
