About Demardi.
Demardi was created long before the company itself came to life. Michael and Anthony, school mates and friends for years, realised their shared passion for building and engineering could create something truly special for Melbourne’s construction scene. Their strong relationship makes working together effortless and reflects in everything we do.
With over 40 years of combined building experience, Demardi delivers a design-led, transparent build experience supported by an in-house team of skilled carpenters and trusted subcontractors. We collaborate closely with architects and interior designers to ensure your design intent is carried through with precision. With one dedicated supervisor from start to finish and a streamlined process backed by real-time updates, we treat every home as if it were our own.
