Architecture- 20 Nov 2016
This is the first time we are carrying out an extension work at our property. Sean worked with us from a very early stage, prepared the drawings, coordinated with the council and ensured that we received the building approval on time. He was always available to advice us (when requested) on design challenges, choosing installers and material choices which we found very helpful. We are very happy with his work and thoroughly recommend him.

Kitchen Fitting- 1 Jan 2023
I have to say that Tyrone who carried the work out for is very professional and commendable. He was always on time and eager to get the work done. His attention to detail is simply quite impressive. Having completed the work i was rather surprised to learn that he called back the next day only to complete a very small detail that he forgot. A small detail that was not exactly noticeable, thus leaving us with satisfactory results. I’m certainly going to recommend their services to anyone who might require their services. Many thanks 👏👏👍

What experience do you have with similar extensions in West End?
