Ken & Karen

We have had 3 houses built by Roland and his team (Ours, my sons and my daughters). We found Roland and his team to always be approachable to any questions or alterations that we had in the design and building of these houses. The quality of his workmanship is of the highest standard and I would use Roland and his team for any future builds.

Lee and Dan’s Review

After shopping around for a builder, we chose to go with Roland and the crew at Mad Keen Constructions who took care of everything to make it super easy on us as first-time home builders. Roland was easy to talk to and explained everything clearly and answered all of our questions every step of the way. Everything we asked to add on or any little change was no issue and the quality and attention to detail is second to none.

I highly recommend Roland, Mariana and the crew at Mad Keen for any renos or home building that you need as you will get even more than what you were expecting.
