About Demardi.
With over 40 years of combined experience, Demardi’s founders Michael and Anthony bring a rare combination of deep technical expertise and a design-led approach that treats every home as a considered piece of architecture, not just a construction project.
Michael & Anthony have been friends since school. That relationship, built on trust, direct communication and shared standards, shapes how every Demardi project runs. Anthony works with you from the initial conversation through to sign-off, while Michael leads the construction phase alongside your dedicated site supervisor, meaning you have a founder involved at every stage of your project, from first meeting to final handover.
Every Demardi project is built by our in-house carpentry team and a consistent group of hand-picked subcontractors. Same people, same standard, on every project we deliver.
