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.

Extensions- 13 May 2026
Agim completed a ground floor extension for me in 2025 and I would not hesitate to recommend him for similar work. The quality of the work was excellent and the team worked tirelessly for months to ensure it was completed on time and for a reasonable price. Agim was able to adapt quickly when any unforeseen problems occurred, always clearly communicating possible solutions to help keep the project moving. Having people in your home can be difficult but Agim is very respectful and considerate, making sure to put our needs first. The results are fantastic and Agim continues to help snag any minor issues that come up. I couldn’t be happier with how things went, testament to his professionalism. Thanks Agim for all your help on this project.
