Extensions- 29 Apr 2019
Liam was very easy to work with and provided a competitive quote with clear end point after a site visit. The job involved stud lining and insulating a 12 x 8m agricultural building, creating a partition wall to divide the space, installing a small internal work room and installing doors. Liam and his team worked quickly and to a high standard to complete the job on time. Following this work we hired Liam to install worktops and storage units all made to our requirements and specifications.

Latest review:
We had two major extensions added to an existing bungalow with a new roof on all of the property including the existing part. the work completed was to a very high standard always a clean and tidy site and peter and his team were very professional. My architect and building inspector made numerous comments on the high standard of quality of work and their knowledge of the work in hand. The work was completed within the timescale even when they had to work in difficult weather conditions but they prioritized their work to allow them complete as much as possible to ensure they did not overrun. The team was fantastic in every way , pleasant to work with and extremely professional. peter strengths was organizing his teams daily tasks ,reliability and conscientiousness to complete work to a high standard . I would not use anyone else but peter for future works and would recommend them 100% to anyone who is considering any building work.
