Bricklaying- 4 Sep 2020
Kept us updated and informed of when job would be done. Dropped bricks off and was due to come back again following week. Due to unforseen circumstances and injury was not able to carry out work for us. Left us bricks with no charge as an apology and again kept us well informed and very apologetic. Would contact again in future if needed any more building work doing.

Landscaping- 22 Jul 2026
Thanks to the team we are set to have a fantastic summer in our new garden room and freshly laid lawn! Jack listened carefully to all our ideas and gave us a really competitive price. He took the time to create a bespoke layout, knowing all it would take extra effort, just to ensure it perfectly suits our needs. The quality of the finished build is top tier! Throughout the project, Jack proved to be a honest, trustworthy, and incredibly knowledgeable guy. His attention to detail and craftsmanship are second to none. He also patiently answered all our questions in detail. Like many big building projects, we hit some minor snags (roof drainage issues and a few delays). But to his absolute credit, he took full responsibility, came straight back to carry out the remedial work, actively suggested solutions to sort everything out. While scheduling can be busy in peak season, his commitment to doing the job right was what mattered most. We’re so satisfied and wish the team every success!

Extensions- 24 Sep 2020
Arran started the works on the day agreed and ensured the build continued on schedule to completion. His attitude to work was very professional and his bricklaying finish was quite meticulous. Very pleasant and obliging to deal with and nothing too much trouble. Have since recommended him to another friend which is something I would never consider unless I had been perfectly satisfied with his works for me.
