Greenstone Construction is a commercial general contractor with operations in Calgary and Edmonton and surrounding communities in Alberta, and in the lower mainland of British Columbia. We have a track record of achieving substantial completion and handing over projects on the initially agreed upon date. We have a rigorous approach to change orders (many of our projects have $0 of change orders) by identifying and mitigating issues before they lead to cost over-runs and time delays. Our residential division focusses on the construction of ICF (Insulated Concrete Forms) custom homes, generally from frost / basement walls, to the roof. We have experience with both acreage development, as well as city in-fills.
