Custom Homes, Renovations and Passive Haus Building
Tailored building solutions with purpose and precision.
At One Bau Group, we bring together smart design and practical craftsmanship to deliver homes that are built to last - and feel good to live in.
Whether you’re starting from scratch, renovating an old favourite, or planning a multi-unit development, we’ll guide you through every step with care and clarity.
Custom New Homes
One Bau Group builds custom homes across Sunbury, North-West Melbourne, Gisborne, Woodend, and the Macedon Ranges. Every build starts with your vision and ends with a home designed around the way you live.
Building a custom home is about creating a space that reflects the way you live, not settling for someone else’s vision. We work closely with you from the very beginning, guiding you through design, planning and construction with a clear and transparent process.
​
From concept through to completion, every detail is carefully considered to ensure your home is functional, refined and built to last. With a focus on quality craftsmanship, honest communication and timely delivery, we create bespoke homes that are tailored to your lifestyle, block and budget.
Renovations
Renovating your home calls for a considered approach - one that respects the character of the existing home while elevating it for modern living. We treat every renovation with the same level of detail and discipline as a new build. From reworking layouts to refining finishes, every decision is made with intention.
​
We focus on creating homes that feel cohesive, functional and built for the way you live — balancing design, craftsmanship and long-term performance. Whether you're updating a heritage home in Woodend, extending a property in Sunbury or reimagining an existing space in Gisborne, we bring the same level of care to every renovation as we do to a new build.
​
The result is a renovation that feels seamless, refined and enduring.
Multi-unit Developments
Multi-unit developments are about more than just building — they’re about maximising return while delivering a quality product to market.
​
We work with developers and investors across Melbourne's north-west and the Macedon Ranges corridor to deliver well-considered townhouse and multi-dwelling projects that balance efficiency, buildability and design.
​
With strong planning, clear communication and a trusted trade network, we ensure your project runs smoothly from concept through to completion, reducing delays and protecting your bottom line.
High Performance Passive Homes
A high-performance home is defined not just by how it looks, but by how it feels to live in. As an Accredited Passive House Tradesperson, director Adam Gazic brings certified expertise to every high-performance project.
​
Through careful design and considered construction, these homes maintain a consistent internal environment, enhance comfort and significantly reduce energy demand.
​
We take a detail-driven approach to high-performance building. With a strong interest in Passive House principles, we focus on how each element of the home contributes to its overall performance, from orientation and insulation through to airtightness and ventilation.
​
The result is a home that feels calm, efficient and enduring - built with purpose, not just appearance.
