Latest review:
Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.

Conversions - General- 15 Apr 2026
Luke and Diti are both amazing guys for this project. Honestly speaking they aren't the cheapest quote, but they are definitely beyond expectations. Luke was the only builder who gave a full transparent quote on each item and what was needed for the conversion. Really quick work and good planning because I have 2 cats and they did everything with enough people onsite to minimise the time. Speaking of work, it is good, we kept in communication and they were always happy to explain and adjust slightly according to my concern/question. Leave this comment after the work has been done for few months and everything is solid.
