  • Engaging GMAC Built for our dual townhouse project was a great decision. Without an architect, we relied heavily on his experience and guidance. He helped us make smart choices that not only look great but added real value to the investment. This was no easy build, coming right in the middle of Covid. With restrictions, shortages, and constant uncertainty, Greg’s project management and resilience really stood out. He kept things moving, found solutions, and always kept us informed. These two beautifully finished townhouses have proven to be an excellent investment and we are thankful to GMAC Built. Greg was flexible, friendly, and genuinely easy to work with. We’d absolutely build with him again.

  • Having worked with GMAC Built over the last ten years, I had seen Greg’s dedication to each job and also knew he had the expertise needed for a dual townhouse project. And as expected, we had a great experience with GMAC Built. From the start, Greg took the time to understand our goals and was upfront about what could be achieved within our budget. As the project went along, we made a few changes on the fly and Greg took it in his stride and worked with us to find practical solutions that kept the design on track and the costs under control. His flexibile and transparent approach made the whole process so much less stressful. We always felt like we were in good hands and were being prioritised. We were constantly amazed at how quickly the project progressed. It was clear that Greg and the team cared about every detail. The end result was a flawless build without blowing the budget. We’d happily recommend GMAC Built to anyone.

  • Our recent renovation project, carried out and managed by Gmac Built, was a complete success from our perspective as clients. Greg liaised easily with the designers, adding some creative innovations and practical solutions during the course of the build. The project started on time and finished ahead of schedule, which reduced our time living remotely. Greg communicated regularly and was always available to answer questions and discuss progress in a friendly and customer focussed manner. Gmac Built has strong relationships with specialty trade teams that were impressive in their timeliness and attitude to Greg’s clients. Any cost variations were explained fully and alternatives offered. We are thrilled with the finished renovation and impressed by Greg’s thoroughness and attention to detail. We highly recommend Gmac Built for high quality construction, project management and customer service.

    —Chris & Paul

  • We recently completed a multi-level renovation with Greg from GMAC Built and couldn't be happier with the experience and the results. From start to finish, their communication was outstanding—clear, consistent, and transparent at every stage of the project. One of the biggest things we appreciated was how well-managed the process was. Although the project went slightly over budget and time, this was communicated well in advance, so there were no surprises or stress. It's rare to find a builder who keeps things so clear and upfront, and it made a huge difference. The quality of the work is excellent, and the post-build care has been just as impressive. Any small issues that came up after completion were addressed quickly and professionally, without hesitation. Greg made what can be a stressful experience into a smooth one. We'd highly recommend him to anyone looking for a reliable, skilled, and trustworthy builder.

  • We were extremely impressed with how quickly our significant renovation progressed. GMAC contracted to do the renovation in eight months, but they completed it in less than six months. Less time renting and more time to enjoy our new home!

    - Mark

  • I am so grateful to Greg for the excellent work he and his team did and for his positive, professional and friendly manner. The more negative stories I hear from others about their builders, the more I appreciate what Greg was able to achieve. I wouldn’t hesitate to recommend GMAC Built.

    - Marguerite

  • We were highly satisfied with GMAC's performance. Greg and his tradesmen were personable and easy to work with. Greg was always a helpful member of the construction team and we were pleased he worked daily on the project without juggling too many other projects. It was especially pleasing to achieve the task in good time, during the exceptional difficulties presented by COVID-19 restraints.
