Architecture- 17 Sep 2025
Overall we are happy with the work that has been done, however the whole experience has been soured by the fact that I am still chasing to have the new hot water cylinder properly commissioned almost 2 years after installation meaning I cannot have it serviced and won't be able to claim on the warranty if things go wrong. My home insurance will also not pay out on any damage that may be caused. The other issue is that the two consumer units that were installed have not been labelled so I have no idea which breaker does what, this is a safety concern. My many attempts to contact Mandeep about this have been fruitless, I'm just being ignored.

Carpentry- 25 Jun 2026
I cannot recommend Liiam highly enough. Before I had even hired him, he went out of his way to sketch up two different design options so I could visualise the finished result. I purchased the balustrade kit through a third-party supplier, and Liiam even took the time to recover my basket and help ensure I had everything needed. He arrived exactly when he said he would, worked incredibly tidily throughout, and his attention to detail was outstanding. Most importantly, the finished balustrade looks absolutely fantastic and has transformed the space. Liiam clearly takes great pride in his work, and it shows in the quality of the finished job. Professional, reliable, meticulous, and a pleasure to deal with from start to finish. I would wholeheartedly recommend him to anyone looking for a skilled and trustworthy installer.

Latest review:
The project lasted from July 2023 to Feb 2024 and comprised of: 1. Single story rear extension with new kitchen and underfloor heating 2. 75m2 patio 3. Internal reconfiguration including removal / installation of walls, new flooring, plumbing (including new boiler), new door frames, doors and skirting, redecoration, carpentry for cupboards 4. Ventilation of existing roof The team are both friendly and professional with Alin always on hand to manage any questions / situations as they arise. The work is clearly costed and every two weeks a valuation takes place to ensure transparency of work undertaken both in original scope and any extras. The quality of the build was excellent, something the building inspector commented on. Alin was recommended to me based on past work, and I in turn would highly recommend him.
