Architectural Homes, Built with Care




Meticulous, design-led residences — delivered with precision, craftsmanship, and integrity.


We build a select number of homes each year.
Each one receives our full attention.


Just share a few quick details to help us understand your project,
and how we can best support your vision.

A Focused Approach to Building




We’re a family-run construction company that’s grown quietly over 40 years.

We take on a limited number of projects each year, allowing us to stay present, responsive, and deeply involved in every detail of your build.

What You Can Expect:

  • Director-Led Delivery
    Your home is built by the people you meet — not handed off. Peter, our founder, leads each project with care and continuity.

  • True Craftsmanship
    Every detail matters. We bring a maker’s eye and decades of experience to ensure your home is delivered exactly as it was designed.

  • Architect-Aligned Process
    We work collaboratively with your architect to resolve complexities, preserve design intent, and ensure the build feels effortless.

  • Recognised Work
    Finalist – HIA Awards. Featured in The Local Project.
    Our builds are quietly celebrated in industry circles and homes across Melbourne.

Built Work That Speaks for Itself


Each home we build is a reflection of the trust our clients place in us, and the pride we take in every detail.

For Those Who Value Design and Precision




We partner with clients who care deeply about architecture, detail, and how things are made;
but who also expect the process to be clear, efficient, and well-managed.

Whatever the scale of your project, we deliver homes that honour design intent while maintaining pace, craftsmanship, and control.


We’re a good fit for those who:

  • Want their architect’s vision realised without compromise

  • Appreciate structure, clarity, and forward momentum

  • See their home as a long-term investment in quality

  • Prefer quiet craftsmanship over rushed volume

  • Value builders who bring calm, focus, and technical excellence to the process
