Extensions- 2 Nov 2017
Mark and the boys have been fantastic. From the professional and comprehensive quote that was provided, we were able to see exactly where the budget was being spent with a payment plan included. Nothing was to much for the team and Mark was always on site to liaise with structural engineers etc to offer his professional opinion and answer any queries. Would highly recommend for any building/carpentry needs.

Handyman- 7 Mar 2021
It was a pleasure to have Sam fit a new 2-level heavy-duty shelf exactly to my specifications. He carefully went over the details, produced some drawings for me to choose from and then made and painted a solid shelf with supports to match the handles of the cupboards below. I am delighted with the result. It is really splendid. Thank you, Sam!

Conversions - General- 28 Feb 2016
Julian was very friendly, flexible and capable in completing a wide ranging job for us; including knocking through a wall to fit a new doorway, bricking up a door way and replacing it with a new window and helping design and construct an above ground fully insulated wine cellar. He also helped with the various building certification visits (which was very helpful as we had limited knowledge of the requirements). We found Julian's advice on construction materials and practicalities very helpful and were very happy with the clarity and level of costs/timing quoted at every stage. He was also flexible and understanding to changes/additions to the scope of work during the project. Julian seemed to be very happy to work to our timetable in terms of work and budget. After and during all the various stages of work Julian made sure to leave the house in good order, so the work was not too disrupting to our lives. We were very happy and would definitely use Julian again (and recommend others to do so).
