Duplex Builder Gold Coast

In 2026, a Gold Coast duplex typically costs from around $750,000 to $1.2 million-plus per dual-occupancy pair, or roughly $2,900–$3,800 per square metre, depending on size, finish level, site slope and whether the lot is being subdivided. Sloping blocks needing retaining and a split-level design sit at the higher end. Every Mintconstruct duplex quote is fully itemised against your design and engineering so your investment numbers hold.

A duplex is two attached dwellings, usually on a single title that can be subdivided into two. Dual occupancy is the broader planning term for two dwellings on one lot. A dual-key home is a single dwelling internally split into two self-contained tenancies under one title — popular with investors wanting two incomes without subdivision. We design and build all three on the Gold Coast.

Yes — this is core to what we do. We're subdivision-savvy: we coordinate the surveyor, town planner and certifier so the duplex is built to be torrens or community-title subdivided, letting you sell or rent each side independently. We'll advise on whether your block and zoning support subdivision before you commit.

Constantly. A well-built duplex or dual-key home gives you two rental streams from one block — strengthening yield and serviceability. We build to a fixed price so your feasibility holds, with finishes chosen for durability and tenant appeal rather than over-capitalising. Many of our duplex clients are repeat investors.

Yes. We deliver duplexes design-and-construct end to end — coordinating designer, engineers, certifier and council from feasibility through to handover and titles. If you already hold plans or a DA, we can value-engineer and build them; if you're starting with land, we'll guide the best dual-occupancy layout for yield and approval.

Yes. We build duplex and dual-occupancy projects across the Gold Coast and into Northern NSW, as well as Brisbane. Each council has its own dual-occupancy and subdivision rules, and our team works to the relevant planning scheme and certifier for your site.
