Extensions- 31 Jul 2016
Nick built a two storey extension which added two bedrooms, bathroom, utility room, downstairs toilet and much extended kitchen. All work was completed to a high standard and all workers were very polite; no problems whatsoever. The extension was delivered mostly to budget with extras clearly explained. I would highly recommend Nick for a trouble free build.

Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

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.

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.
