What we build

One builder for your home and your investment.

We build custom homes, duplexes, and co-living and group homes across Sydney and Greater NSW. Whether it's your forever home or your next investment, you get the same thing: clear costs, honest timelines, and hands-on supervision from start to finish.

Who we help

Two clients. One standard.

For Homeowners

Your home, built right.

Building your own home is often the biggest decision of your life. You want a builder you can trust with something this personal. We bring real trade experience and engineering discipline to every custom home — and we keep you informed at every step, so there are no surprises along the way.

For Investors

Where investors build their future.

Duplexes, co-living and group homes are about returns. You need clear costs, disciplined delivery and a builder who understands how a project performs long term — not just how it looks at handover. We treat your money and your timeline as if they were our own.

01 — Duplex Developments

Dual-occupancy builds that grow your portfolio.

A duplex is one of the smartest ways to add rental income and capital growth on a single block. We manage the whole process — from working out if your site stacks up, through council approval, to a finished pair of homes ready to rent or sell.

  • Feasibility and site assessment before you commit
  • We handle DA lodgement and council objections
  • Comfortable with flood zones, OSD tanks and tricky conditions
  • Built for rental income and long-term capital growth
Proof point

A 1,400 sqm Carlingford block in a flood zone — the first duplex of its kind there. We adapted the design to meet every council objection and delivered it approved and complete.

Co-living group home in Kingswood
02 — Group Homes

Co-living and group homes built to perform.

Purpose-built co-living and group homes are designed to meet strict compliance rules and deliver strong, steady rental yields. These are complex builds — and complex is what we do best.

  • Shared housing from 8 to 12+ bedrooms
  • Designed for compliance and rental yield
  • Community housing experience
  • We solve difficult sites instead of cutting scope
Proof point

A 10-bedroom, 10-bathroom co-living build in Kingswood on a difficult block. We added a retaining wall to manage water from higher neighbours and turned a site many thought unbuildable into a high-performing asset.

03 — Custom Developments

Architecturally designed homes, built to your brief.

Steep sites, luxury finishes, complex builds — all welcome. We combine hands-on building experience with an engineering background, so the hard details get solved properly instead of passed on to you.

  • Built to your architect's brief, or we help you shape one
  • Steep and difficult sites are our specialty
  • High-end finishes and complex structural work
  • Construction-led advice so the design can actually be built
Proof point

A steep Seaforth site with a pool and sauna built into the design. We stabilised the site first, then delivered a luxury home with a water-view balcony — the client's key feature.

For property investors

Most builders don't think like investors. We do.

On an investment build, the finish is only half the job. What really matters is whether the numbers work, the timeline holds, and the property performs for years after handover. Here's the difference that makes.

The usual problem

  • Builders who don't understand DA or council requirements
  • Costs that creep up with no warning
  • Loose sites, slow progress and guesswork
  • No one thinking past the handover date

The Auzzy difference

  • We pick the right approval path early and manage the council process
  • Cost-plus with full transparency through Wunderbuild — variations flagged early
  • Daily planning, daily tracking and a dedicated supervisor
  • We design and build for long-term performance, not just handover
