Extensions- 21 Jul 2025
I recently hired AK construction to build an extension on my home, and I am beyond impressed with their work ethic, flexibility, and outstanding customer service. The extension was built to the highest standard—flawless craftsmanship, attention to detail, and seamless integration with my existing home. The team was punctual, tidy, and respectful throughout the project. What really stood out was their willingness to help, even beyond the contracted work. When I had some DIY tasks, they offered advice, lent me tools, and even stepped in to assist where they could—despite not being obligated to do so. Their kindness and professionalism didn’t waver, even when I declined additional quotes for other work. They stuck to the timeline and budget with no surprises. Communication was excellent, and they treated my home with care as if it were their own. I can’t recommend Ali and AK Construction enough—they’re trustworthy, skilled, and genuinely care about their clients.

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.

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.

TA Bhatti constructions did an excellent job in renovating my house, it was a 6 months long job where they pulled apart all the internal parts of the house and rebuilt it all. They did an excellent job in putting a new Kitchen, 2 bathrooms, new wiring, new plumbing and everything else. The thing I liked most was their finishing which was next to none. I will happily recommend TA Bhatti constructions to anyone looking to renovate their house or looking to do extensions or Loft conversion.

Bathroom Fitting- 2 May 2024
I have employed DL Construction to install a new kitchen and bathroom. They are still working in my house but so far their attitude towards their task and helpfulness have been exceptional. I can not comment about the final product yet but I am sure everything would be finished to a high standard. Nothing seems to be a problem for Javi. He always says 'yes please' and I think that is his middle name. I couldn't have asked for better. Well done (so far) Javi and everyone in DL Construction.
