The Founders
Mitch Chan
Founder & Director — Site & Delivery
Mitch has been building on the North Shore and Northern Beaches for over 11 years. He holds a Certificate IV in Building & Construction and a Certificate III in Carpentry & Joinery — and he didn't stop there.
Mitch became fascinated by what was happening behind the walls. What was the vapour pressure doing? Where was the thermal bridging? Was the EMF from the wiring layout going to affect the family sleeping on the other side?
"I kept seeing the same problems behind the walls of homes that looked beautiful at handover. Nobody was asking the right questions before they built."
That curiosity led him deep into building biology and healthy-home science — specialist fields within residential building. He's currently completing an Advanced Diploma in Building Biology, is a certified graduate of the Healthy Home Materials Mastermind (2025), and is a certified Passive House Tradesperson.
Outside of work, Mitch is married and spends his time outdoors — hiking, adventuring, and looking for what's over the next ridge. That same instinct to push further drives how he approaches every build.

Tom Stewart
Director — Pre-Construction & Client Experience
Tom brings 14 years of custom residential construction experience — and a degree in Philosophy, English Literature, and Latin from the University of Sydney.
That combination sounds unusual. It isn't. Building a custom home is one of the most complex things most people will ever do. It requires clear thinking, careful communication, and someone who can translate between the world of architects, engineers, clients, and tradespeople without losing anything in the process.
"Most project blow-outs don't happen on site. They happen in the weeks before a shovel goes in the ground — when nobody stops to ask the hard questions. That's where I live."
Tom runs AGATHĒ's pre-construction process — a structured approach to planning, budgeting, and design alignment that happens before construction starts. His clients call him the PAC Man. It's the phase of a build Tom has made his speciality — the upfront planning that makes the rest run smoothly.
Tom is married with a growing family. He reads widely — history, philosophy, narrative — and spends time sailing, kayaking, and finding excuses to be on or near water. He approaches building the way he approaches most things: with rigour, and the belief that it's worth understanding something properly before you begin.
