A great experience with Spacemaker who extended our home in Alphington and we are very happy with the final result. Fiona was a good listener and planned just what we wanted, and the works were completed to a high quality for the quoted price with few delays. Thanks very much in particular to Fiona, Rob, Will, Rom and Tim

Tim, Paul, Mitch, Zac and Ben were not only easy to work with but were also knowledgeable and professional. As project managers by trade, we both know how hard it can be to coordinate all the moving parts to ensure delivery. Add COVID to the mix and Paul had his work cut out for him. To his credit, he handled all the challenges like a champ and kept us informed throughout the build.
Mitch, Zac and Ben delivered exceptional craftsmanship with service beyond expectations. Beyond the SpaceMaker team; additional services that were contracted to the build were also amazing. Joe, in particular
