Groundwork & Foundations- 3 Sep 2025
Work was partially completed we agreed on plantation of 60 planters he spent the first part of the day regularly talking on the phone with a 1 hour break. When I asked him politely to come and join the rest of the team so we don’t lose time in order to complete the job as he was on the phone quite frequently he returned telling me I was on the phone with my mother do you have a problem I will come when I am ready. In general quite a rude individual. He walked away and was paid in full but not hire him again as he did not honor what we agreed on and did the bare minimum for quite a pricy wage.

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.
