Kitchen Fitting- 11 Oct 2018
Mohsen went above and beyond with our kitchen face lift. He did exactly as asked, to a very professional standard. Mohsen is very hard working, has high standards and was reliable. He also suggested ways to improve our kitchen, and corrected some previous poor work from other builders! We love the job and will definitely use Mohsen and his team again for future work.

We recently had a loft extension completed along with wooden flooring throughout the house, underfloor heating installation, and a full silicone render — and we couldn’t be happier with the results! The team were an absolute pleasure to work with from start to finish. Their innovative and creative thinking really set them apart — they found smart solutions to challenges and helped us maximise space and style in ways we hadn’t even considered. What impressed us most was their attention to detail and how clean and tidy they kept the site throughout the project. It made a huge difference knowing the work was being done to such a high standard, without the usual mess and disruption. Whether it was a small detail or a big task, nothing was ever too much trouble. No job was too big or small — they approached everything with the same level of care and professionalism. If you’re looking for a reliable, forward-thinking team who take real pride in their work, I couldn’t recommend them more highly!

Extensions- 17 Nov 2022
AT Line Construction built our extension and worked on the remodel of the inside of our flat. We are extremely happy with the results. Adison and his team are very professional and friendly. They were able to deal with any changes and problems that came up quickly and sensitively. Part of the build was to renovate a small disused swimming pool - this was a tricky job, and they were able to help us creat an amazing pool. We would definitely recommend them.

Bathroom Fitting- 1 Jun 2025
I am really pleased with my new bathroom. I needed a partial refurb and new flooring due to a previous leaking shower. Landi did a great job fitting new taps, shower and sink in my bathroom. He was also able to advice me on the best sink and radiators and helped me to choose the right fittings when I was ordering. I didn't like the colour of the sealant and he redid it in another colour with no issues. He was efficient, friendly and completed the job in good time. Communication was always swift and I would be happy to recommend him to others and use him again for other jobs. Thanks Landi for great service.

Extensions- 22 Dec 2022
Imran is a contractor who is personable and is trying hard, but at the end relies on different teams of builders to carry out the work. His knowledge of building work appears at time limited. In our case, this has often led to poor communication/hand-over, extensive delays and often poor (if not careless) craftsmanship. Very stressful. We now have builders (family business) finalising our project.

The london Loft and Kitchen Company
Rating: 4.5 out of 5
Extension Builder in Mitcham
We are a southwest London Based loft and kitchen extension specialist. Our working area is very small with 90% of our jobs in Wandsworth and any work outside this area is never more than a mile or two away. With over 15 years experience in this area we know inside and out how these properties were built so when it comes to structural alterations you couldn't be in safer hands.

Extensions- 16 May 2017
Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom
