Groundwork & Foundations- 2 Dec 2025
Working with Sebastian and Jonny was an absolute pleasure from start to finish. From day one, it was clear they and their team take genuine pride in their work and it shows in what they do. The entire team was incredibly courteous and professional, and as we have a mid terraced house they did their best keeping the hallway clean and dust free throughout the project. The quality of their work speaks for itself, and their attention to detail made the whole experience stress-free. I would highly recommend them without hesitation and would absolutely work with them again.

Extensions- 28 Sep 2018
Johnny was very nice to deal with. When there were problems they were quick to find ways to rectify them. They started at short notice& finished on time which I was very impressive. We got a no. of quotes,Johnny was middle of the range but with a better level of service than others. Johnny was very open about when things might cost more &gave us the option if we wanted to proceed. A few things to note: -this was our 1st experience of any building work &we should have remembered they are builders, not designers -we both work long hours &so most days didn't see the team to get an update or brief them. This meant a few things were missed or miscommunicated - while most of the team were lovely the electrician used was horrible to deal with. He got very cross about requested changes, didn't deliver everything requested &just did silly things like putting in a light switch with 2buttons where there was only one Light or hanging lights incredibly low when we had given measurements of where we wanted them - we got Johnny's team to build some extra storage for us which on the whole was fine but some things weren't centred or for example the wine rack they built was wonky Overall, it was a good experience and we would recommend them but would suggest be home to oversee the work more than once a week (must be true of any building work!) and get your own electrician. Very happy to talk to people and give references-the house looks great now.
