Townhouse & Duplex Design Plans
Multi-Dwelling Building Design for Brisbane
Feasibility-led townhouse and duplex building design plans for Brisbane developers, investors and owners. We help you understand what your site can yield, then design multi-dwelling plans that respond to Brisbane City Plan 2014 and move efficiently through council approval.
As a QBCC Building Design - Low & Medium Rise licensed practice (Licence No. 15436033), we can lawfully design multi-residential developments up to three storeys — covering most townhouse and duplex projects across Brisbane's Low-medium density residential and character zones.
Multi-Dwelling Projects We Design
From a single dual-occupancy to a multi-unit townhouse development, we design practical, marketable multi-dwelling plans suited to your Brisbane site and budget.
Duplexes & Dual Occupancy
Side-by-side or front-and-rear duplexes designed to maximise yield and amenity on standard and corner lots, with separate titling in mind.
Townhouse Developments
Two and three storey townhouse rows designed for efficient circulation, private open space, parking and streetscape appeal under the relevant codes.
Small Lot & Infill
Clever small lot and infill designs that work within setbacks, site cover and private open space requirements to unlock compact Brisbane sites.
Investor & Co-Living Layouts
Layouts optimised for rental returns and co-living configurations, balancing dwelling mix, parking and council amenity requirements.
Brisbane Planning & Compliance Expertise
Multi-dwelling feasibility lives and dies on the planning detail. We assess your site against Brisbane City Plan 2014 from day one so you can make decisions with confidence.
Zoning & Yield Assessment
We assess your zone — particularly Low-medium density residential (LMR) and Character residential — and the relevant neighbourhood plan to estimate realistic dwelling yield.
QBCC Medium Rise Licensed
Our Medium Rise licence lets us lawfully design multi-residential buildings up to three storeys — a key requirement many building designers can't meet.
Overlay & Constraint Review
We review flood, overland flow, traditional building character, and other overlays that affect what — and whether — you can build.
Approval Pathway Guidance
We identify whether your project needs a Material Change of Use (MCU) Development Application and how reconfiguring a lot (subdivision) fits the program.
Townhouse & Duplex Feasibility by Zone
A general guide to how common Brisbane zones and overlays affect multi-dwelling potential. Outcomes vary by neighbourhood plan, lot size and overlays — we confirm the specifics for your site.
| Zone / Overlay | Typical multi-dwelling outcome | What we check first |
|---|---|---|
| Low-medium density residential (LMR) | The primary zone for townhouses and duplexes — typically two to three storeys depending on the precinct. | LMR precinct, neighbourhood plan, height and density provisions |
| Low density residential (LDR) | Generally limited to a dwelling house or dual occupancy; multi-unit townhouses are usually not supported. | Whether dual occupancy is an accepted or assessable outcome |
| Character residential (and Traditional Building Character Overlay) | Multi-dwelling is possible but constrained — demolition of pre-1946 homes is controlled and original character must be retained. | Pre-1946 status, demolition controls, retention of the original house |
| Flood / Overland Flow overlay | Buildable in many cases, but habitable levels and car parking must respond to the Defined Flood Level (DFL) and freeboard. | DFL, freeboard, ground-floor use and resilient materials |
| Small lots | Compact duplex and small lot housing can work where setbacks, site cover and private open space are met. | Setbacks, site cover, private open space and parking |
Our Townhouse & Duplex Design Process
From an initial feasibility view through to approval-ready plans, we keep your multi-dwelling project moving.
Feasibility & Site Analysis
We review your zone, neighbourhood plan, overlays and lot dimensions to estimate realistic yield before you commit.
Concept & Yield Design
We develop concept site plans and unit layouts that balance dwelling yield, amenity, parking and streetscape under the relevant codes.
Approvals Coordination
We prepare the documentation for the likely approval pathway — typically a Material Change of Use (MCU) Development Application — and coordinate the required consultants.
Construction Documentation
We produce detailed plans ready for building approval and builder pricing, coordinating structural, civil, hydraulic and certification input.
Townhouse & Duplex FAQs
Common questions from Brisbane developers and investors
Can I build townhouses on this Brisbane block?
It depends primarily on your zone under Brisbane City Plan 2014. Townhouses are generally supported in the Low-medium density residential (LMR) zone, while the Low density residential zone usually only allows a dwelling house or dual occupancy. We assess your zone, neighbourhood plan and overlays to give you a realistic view of yield before you commit.
What overlays or neighbourhood plans affect feasibility?
Flood and Overland Flow overlays affect floor levels and car parking; the Traditional Building Character Overlay controls demolition and form for pre-1946 homes; and many areas have a neighbourhood plan that adjusts height, density and built-form outcomes. We review all of these against your site early, because they directly change what is achievable.
Can the existing house be demolished?
If the existing house is pre-1946 and within the Traditional Building Character Overlay, demolition is controlled and usually requires a Development Application — and is often refused for intact original homes. Post-1946 homes in development zones are generally able to be removed. Confirming this is one of the first checks we make.
What approval pathway is likely?
Most townhouse and duplex projects require a Material Change of Use (MCU) Development Application with Brisbane City Council, and often a reconfiguring a lot (subdivision) application for separate titles. A Building Approval (BA) follows for construction. We identify the likely pathway during the feasibility stage.
What should I check before buying or making an offer?
Before you commit, check the zone and any precinct, the neighbourhood plan, overlays (especially flood, overland flow and character), the lot dimensions and frontage, and whether any existing house is pre-1946. We offer a feasibility assessment so you can make an offer with a clear understanding of realistic yield and approval risk.
Are you licensed to design three-storey townhouses?
Yes. All Aspects Design Studio holds a QBCC Building Design - Low & Medium Rise licence (No. 15436033), which lawfully permits us to design multi-residential developments up to three storeys. This covers the large majority of townhouse and duplex projects across Brisbane.
