Mastery Co is seeking an experienced Carpenter for a fixed-term contract role based in Revesby, Sydney, working on an $800,000+ residential extension and renovation. The contract runs for approximately six months, or until project completion. The project is currently in the demolition phase, so an immediate start is ideal. As a Design + Construct firm, Mastery Co produces all the plans, documentation, and 3D models for projects in-house — giving clear, well-organised drawings and cutting lists to work from on site, with the Director Mitch on hand throughout both the design and construction process.
