Four ways we work with Melbourne homeowners.
Whether you're starting with a sketch on a napkin or a fully approved set of plans, we hold your project end-to-end — design, council, construction, handover.
Design + Build
One relationship from first sketch to final handover.
Custom Homes
Bespoke homes designed around the way you live.
Full Home Renovations
Major renovations and extensions, done right from day one.
Knockdown Rebuild
Stay in the suburb you love. Build the home you've imagined.
Why Demardi
Built on standards. Held together by people you can actually call.
Matched to the Right Designer
We assess your brief, budget and personality, then introduce you to the right designer or architect from our trusted collaborator network. Not one size fits all — the right fit for your specific project.
Client Portal & Real-Time Visibility
From the moment you sign, you have a dedicated portal with real-time project visibility. You'll always know what's happening. No chasing, no surprises.
Genuine Craftsmanship
Our in-house construction team includes tradespeople who've been with us since their apprenticeships. Long-term trade partnerships. Consistent standards. Every single time.
Selective, Not Volume
We run a limited number of projects at a time. Not because we have to — because that's how we keep the standard high.
Our work
Recent projects across Melbourne's eastern suburbs.
Recognition
Awards and features earned, never bought.

S4 E12 — 'Tranquil Oasis', Warrandyte NorthWhat our clients say
"We were never left guessing — and that meant everything."
"We called upon Michael and the team at Demardi to run with an extensive interior renovation. They handled the job well and we are thrilled with the end result. They have given life to the thoughts and discussions we planned with the architects."
"Michael and the Demardi team were fantastic. They delivered what they committed to, did a great job and left the job with a clean space (not all trades do this). Thanks team, highly recommend!"
"We had a superb experience and result with our renovation in Mitcham this year. We chose Demardi based on their professional social media and their work looked amazing. Right from our initial meeting, Anthony understood our vision and expertly fleshed out our ideas and found things we hadn't thought of that would improve the result."
