Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.

Groundwork & Foundations- 24 Jul 2026
A great team you can trust. I’m a cautious customer, but they immediately put us at ease with their professionalism and obvious experience. We needed a concrete slab pumped into a long, narrow extension with access from one side only, and they managed the entire process smoothly from start to finish. The result was a perfectly level, high-quality slab. Thank you!
