Built Around You
Two Homes, One Block, Done Properly
A duplex is one of the smartest moves you can make with a decent-sized block. Live in one side and rent the other, build both to sell, or keep one for family. Whatever the plan, the build needs to be done by someone who knows how your type of block behaves.
But before contacting a builder, an owner must have three things in place before we can give you any advice or ideas
- Get finance pre-approval
- Find and buy your land
- Check council planning rules for the block
Once an owner has these sorted, we can handle the full process feasibility, design, council approvals and construction.
One team, one point of contact, from the first site visit through to handover.
WHY BUILD A DUPLEX
Why a Duplex Makes Sense
- Maximise your land: On 600 sqm or more in Brisbane or the Redlands, there’s a fair chance you’re sitting on a duplex opportunity. Two dwellings, each with its own entrance, yard and street presence.
- Dual income: Two rental incomes from one property, in a market where rental demand keeps climbing.
- Live and invest: Build a home you’d want to live in and let the other side cover a decent chunk of the mortgage.
- Often simpler than subdividing: A duplex on one title skips much of the separate driveways, service connections and surveyor fees that come with a full subdivision.
- Future flexibility: Sell one side later, move family in, or switch from owner-occupied to fully tenanted.
Dual-Occupancy Approvals
Whether a duplex is straightforward on your block comes down to your zoning and the overlays that apply. Council looks at minimum lot size, frontage, setbacks, private open space and car parking. Some sites are approved through a code-assessable pathway; others need impact assessment. We assess your site against the current planning scheme first, so you know the approval pathway before you spend money on a full design.
What Drives the Cost of a Duplex Build
- Block size, slope and soil: The site works needed before you build up.
- Existing structures and services: Any demolition, service relocation or new connections.
- Design and specification:The finish level you build to for your market.
- Approval pathway: A more complex assessment adds time and consultant input.
We lay these out early so you’re deciding with the real numbers, not a rough estimate.

Duplexes Built with Certainty.
Delivered With Confidence.
Our six-step process is the result of years spent delivering finely crafted custom homes across Brisbane.
It’s structured, deliberate, and built to give you clarity, confidence, and a standard of care that mirrors the quality of the home itself.
Site and Yield Assessment
Before anything gets drawn up, we come out to your block and do a proper check. Zoning, lot dimensions, slope, easements, flood overlays, neighbourhood character codes, we look at the lot of it. If a duplex is viable, we’ll tell you exactly what’s achievable.
Design and Planning Strategy
We design custom floor plans that suit your block, meet council requirements, and give both dwellings the space and privacy they need to feel like proper standalone homes. We work with you on layout, orientation, finishes, and flow
Development Approvals and Compliance
We manage the full development application process with Redland City Council or Brisbane City Council, depending on your location. That includes any overlay responses, neighbourhood character assessments, engineering reports, and whatever else the planners ask for.
Construction and Site Delivery
One dedicated site supervisor runs your build from slab to lock-up to finishing. You’ll get regular updates, clear timelines, and no surprises on cost. We use trusted local trades we’ve worked with for years, and we hold them to the same standard we hold ourselves.
Subdivision and Project Finalisation
We take care of titling, final inspections, and final certification, giving you the paperwork and preparation needed to rent, sell, or retain each home.
Handover with Market-Ready Finish
We walk through every room with you. Full defect inspection, all compliance certificates sorted, and a home, or two, that you’re genuinely proud to own. We don’t disappear after handover either. If something needs attention, we’re ten minutes down the road.
