Extensions- 18 Jan 2023
We highly recommend THG building solutions, they have built a double story extension for us, and from start to finish they were always on time, polite and professional on every aspect. Most importantly they delivered what was promised according to the initial budget and on time! No delays or surprises, just honest and reliable service. We have been approached by several neighbors to comment on how beautiful the extension looks and how quickly it was all done! Overall we’re very happy and glad that we chose Charles and his team as our builders.

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.

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.
