Duplex and Dual Occupancy Builders — Brisbane and Gold Coast
Duplex and dual occupancy construction is one of the most effective ways to maximise the return on residential land in South East Queensland. Innovare Builders delivers investment-grade duplex and dual occupancy projects for property investors, self-managing superannuation funds and owner-occupiers looking to generate rental income or provide secondary accommodation.
We build dual occupancy projects across Brisbane and the Gold Coast, with strong knowledge of the planning rules that apply in each council area.
Understanding Dual Occupancy in Queensland
A dual occupancy involves two dwellings on a single lot. This may be a duplex (two dwellings side by side), a dwelling and a secondary dwelling or granny flat, or two dwellings one behind the other. The planning rules governing dual occupancy vary by local government area, lot size, zoning and frontage width.
Brisbane City Council’s medium density and low-medium density zones permit dual occupancy on appropriate lots, subject to the council’s development codes. Gold Coast City Council has similar provisions within its planning scheme.
We assess feasibility, design options and likely yield at the outset of every dual occupancy enquiry.
Investment Returns and Yield
A well-designed duplex or dual occupancy on an appropriately located block can generate significant rental yield — both units can be leased independently, or one occupied and one tenanted. In Brisbane suburbs like Coorparoo, Camp Hill, Taringa and Indooroopilly — where demand for well-presented rental accommodation remains high — a dual occupancy build represents a sound investment.
We build to investment-grade specifications: durable materials, practical layouts, low-maintenance finishes, and full compliance with the National Construction Code and relevant tenancy standards.

Common questions
Can I build a duplex on my Brisbane block?
It depends on your block’s zoning, size, frontage and shape. We can conduct a feasibility assessment to determine what is permissible on your specific site.
Can I subdivide a duplex into two separate titles?
Lot subdivision, community title and strata title options all have different requirements. We can guide you through the options relevant to your project.
How much does a duplex cost to build in Brisbane?
Costs vary significantly based on design, size and specification. As an indicative range, a dual occupancy in Brisbane might cost between $650,000 and $1.5M+ for the construction of both dwellings combined, depending on specification. Contact us for a project-specific discussion.
How long does a duplex build take?
A typical duplex takes 12 to 18 months from construction commencement. Total project duration including design and approval can be 18 to 30 months.
