Melbourne Duplex Builders Who Understand Development
The biggest mistake first-time duplex developers make is designing before understanding planning controls, council restrictions, overlays, and real construction costs. That’s where we’re different.
Before any design work begins, we complete a detailed duplex feasibility assessment to determine:
- Whether your block is suitable for a duplex
- What council is likely to approve
- How many dwellings can fit on the site
- Potential development risks and constraints
- Estimated development and construction costs
- Whether the project stacks up financially
Is your block suitable for a duplex?
Every council in Melbourne has different planning requirements for duplex developments. Our team assesses zoning, minimum land size, site width, vehicle access, easements, neighbourhood character, tree overlays, private open space, ResCode (Clause 55) compliance, and slope considerations.
A duplex development can generate rental income, increase land value, create long-term wealth, allow you to build and sell for profit, support multi-generational living, and replace an ageing home with two modern dwellings — creating significantly more value than renovating.
Duplex development costs
Many developers underestimate the real costs involved. Additional costs can include open space contributions, service upgrades, stormwater systems, retaining walls, demolition, driveways, subdivision, and council contributions. Understanding these early is critical to project viability.
Why Choose Great Dane Homes?
We manage the entire process from feasibility and planning through to construction and subdivision.
Our duplex designs are aligned with realistic build costs from day one to help reduce budget blowouts and redesigns.
We understand Melbourne council planning requirements, dual occupancy regulations, and approval pathways.
No generic templates. Every duplex is designed specifically for your site and goals.
We believe successful duplex projects are built on honest advice, realistic expectations, and proactive communication.
We use an external private inspector for increased oversight and accountability, giving you total peace of mind.
Our Duplex Design & Build Process
Duplex Feasibility Assessment
We assess planning overlays, site constraints, council requirements, and project viability to give you clarity before committing — reducing risk and avoiding costly surprises.
Development Strategy Planning
We help determine the best strategy for your goals — build and sell, hold and rent, or develop for family — and identify subdivision and ownership considerations early.
Custom Duplex Design
Every duplex is tailored to your block, council requirements, budget, and resale appeal. No generic templates — just designs built to maximise functionality and return on investment.
Town Planning & Council Approvals
We manage the complete planning process — drawings, applications, council communication, and RFIs — to improve approval success and reduce delays.
Build Cost & Feasibility Review
We identify all project costs upfront — construction, subdivision, site works, stormwater, demolition, and landscaping — so your duplex remains financially viable from day one.
Working Drawings & Building Documentation
Once approved, we finalise engineering, soil tests, surveys, working drawings, and building permits — every detail coordinated before construction begins.
Duplex Construction
Our team manages the entire build — site preparation, quality assurance, compliance checks, and final handover — delivering high-quality duplex homes built for durability and resale appeal.
Subdivision & Completion
We handle compliance inspections, subdivision, landscaping, stormwater, and Certificate of Compliance processes — ensuring your project is ready for titles, sale, or rental.
