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.

Converting your loft into a beautiful living space may seem like a daunting task, but the results are always going to be worth the painstaking process. The loft conversion procedure does not have to be that difficult; all you require is to hire right people to do the right job.

Extensions- 17 Apr 2019
My extention was left incomplete by a incompetent builder, I had plenty builders coming around for quotes until I decided to go with Peter & Chris after receiving their detailed quote with everything explained in blank and white. I am extremely happy with my choice, as they did a great job finishing the project on time and most importantly great finishes. Peter has an amazing interior design taste, I would definitely recommend picking his brains, Chris on the other hand is very experienced and knowledgeable in building, both work very well together as well as his labourers are very respectful and hardworking. I recommend Peter & Chris to anyone who wants a stress free project. An above and beyond service !

Michael was responsible for organising and overseeing my self build project, including the demolition of the old house and site preparation. The new detached house is approximately 5000 square ft over four floors including a basement. Michael's diligence, professionalism and reliability were exceptional. I have also used Michael on other small projects and have been equally impressed. Above all, i have found him very trustworthy. I would happily discuss the projects he has been involved with anyone considering offering Michael a project to carry out.

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.
