Kitchen Fitting- 13 Dec 2025
Paulo and team came to help me renovate my kitchen, they've done an amazing job on a very old kitchen with many deeply neglected issues including having been flooded several years ago. Excellent quality of work, very skillful - I am a bit of a perfectionist. They were sensitive to my budget and helped me source the best deals on units and advised me on what worktops to get and always available with advise and guidance that was honed with decades of experience. I felt they took on the job as if they were working on their own house - getting the best materials and work done within the budget. Paulo and team worked very hard and I felt they took care of every little detail, checking with me what I wanted and gave me options while pointing out the pros and cons with patience and good nature. 10 out of 10!

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.

I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

Quality Builders completed a remarkable domer and loft conversion for us on 2/10/2023, and we couldn't be more pleased with the results. From the outset, their professionalism and attention to detail were evident. The initial consultation was thorough, and they took the time to understand our vision for the space. Throughout the project, communication was excellent, with regular updates on progress and any necessary adjustments. The craftsmanship displayed by Quality Builders was exceptional. Every aspect of the conversion, from structural work to finishing touches, was executed with precision and care. Their team of builders and contractors demonstrated expertise and skill, resulting in a finished product that exceeded our expectations. Not only did Quality Builders deliver on time, but they also adhered to budgetary constraints without compromising quality. Their transparency and honesty throughout the process gave us peace of mind and confidence in their abilities. The transformation of our space is truly remarkable. The addition of the domer and loft has added both aesthetic appeal and practical functionality to our home. The new space is light-filled, spacious, and seamlessly integrated with the existing structure. Overall, we cannot recommend Quality Builders highly enough.

Roofing (Pitched)- 8 Jan 2026
Suad was straightforward and professional to deal with. He inspected the issue, explained the likely cause of the leak, and carried out the agreed repair without suggesting unnecessary additional work. Communication was clear, costs were as discussed, and access was arranged safely. The scaffold was left in place to allow the repair to be checked after rainfall. Overall, a satisfactory experience.

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!
