  • We first approached Rossmark to discuss a significant re-design and renovation of our family home in late 2020. They were our first choice based on the recommendation of friends and their ability to offer a full package of services from … More design through to DA approval, project management and construction.
    From the first, we found Rossmark to be honest, responsive and generous with their time and experience. Our first contact was with Matt who listened to our concerns about the existing rooms and flow of the house and came up with an ingenious design.
    After receiving DA approval, Peter, Glen and the team took over the project management and construction of our job. They managed every aspect of procurement and trades and, despite being shut down for a period due to COVID and the associated difficulties with obtaining materials, still managed to bring in our job on time. We were kept up-to-date with every aspect of the job throughout the entire construction period and nothing was too much trouble for them.
    The quality of work was exceptional and the final product is even better than we could have hoped for. We are so happy that we decided to undertake this renovation as it has made a considerable difference in the way we use our home and, with Rossmark doing all the heavy lifting, the entire experience was a pleasure. We would highly recommend Rossmark for any residential building project.
