The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!

Extensions- 3 Sep 2013
Kel and his team worked on my single storey extension with bifold doors and glass roof. He also did some landscaping in my garden, replacing the fencing and installing a raised patio with cedar battens to the side. Overall I was very pleased with the work Kel did. He is a good communicator and frequently visited the site to keep on top of the work. Kel was happy to discuss requests and was flexible with design changes. The bulk of the work was completed on time with just some minor snags remaining, but the finish is excellent. It's been a long and stressful journey, but it's been easier with the friendly support and professional approach Kel has taken to his job. I'd be happy to recommend Craft of London and provide a reference on request.

Kitchen Fitting- 20 Oct 2026
I contacted Cubitt Wren to ask for a very specific assessment report on part of my property which I needed to present at a Tribunal. I was aware that this was an unusual commission and required both insight and understanding of the particular evidence required. James, who I was dealing with completely grasped what he was being asked to do. He understood the brief, which was certainly not something he was usually asked to do and he responded with a detailed report giving exactly the conclusion I had hoped for. I was impressed that I did not have to chase him or nag him about the urgency of this report and I was really happy with the swiftness of his response. I was kept updated during the process and he was super-responsive. I would highly recommend this company’s services at any time and I will definitely be using them again.
