Dual Occupancy in Melbourne: Step by Step Guide

Building two homes on one block can be an excellent way to maximise land value, increase returns and create flexible living options. Success depends on a clear process and good project management. Here is a straightforward guide to the typical stages in a dual occupancy development.

Step 1. Assess Your Site

Before starting a dual occupancy project, it is essential to confirm that your site is suitable and the development is financially achievable. Early site assessments review council regulations, zoning, overlays and design constraints to identify potential challenges before they become costly.

This upfront assessment ensures your concept not only meets planning requirements but also aligns with your budget, giving you confidence to move forward with the right strategy.

Step 2. Choose Your Floor Plan and Façade

The right design depends on your block’s size, shape, orientation and surrounding streetscape. Each council has its own rules, so selecting compliant plans and façades will speed up approvals and enhance long term value.

This stage balances liveability, functionality and market appeal, ensuring that both dwellings meet planning rules while maximising design opportunities.

Step 3. Secure Preliminary Work

Once you are satisfied with your concept and indicative pricing, the next step is to commission essential preliminary work. This usually includes site surveys, soil tests and initial planning preparation.

Completing these tasks early allows the project team to prepare accurate documentation and avoid unexpected issues during council review or construction.

Step 4. Select External and Internal Colours

For planning submission, external colours and materials need to complement the local streetscape and meet council expectations. Once the exterior is finalised, attention shifts to the interiors.

You can create matching schemes for both dwellings or tailor each to appeal to different lifestyles or rental markets. Thoughtful design choices ensure each home is both functional and market ready.

Step 5. Formal Contract and Planning Submission

With designs and finishes resolved, the formal building contract is prepared. Once signed, the planning application can be lodged with council. This stage often involves coordination with planning officers, arborists and consultants to ensure full compliance and to maximise the chance of timely approval.

Step 6. Demolition and Site Preparation

If the project involves replacing an existing dwelling, demolition takes place once permits are granted. Preparation work such as disconnecting services, sewer capping and electrical upgrades is carried out at this stage.

The site is then cleared, cleaned and made build ready, ensuring a smooth transition into construction.

Step 7. Begin Construction

With working drawings complete and the building permit secured, construction can commence. A site manager oversees the daily build, while regular updates keep you informed throughout the process.

The project progresses through each stage until handover, when the new dwellings are ready for occupancy or sale.

Final Thoughts

Dual occupancy can transform a single block into a more valuable and flexible property. By following a structured process, addressing planning requirements early and managing each step carefully, you can avoid unnecessary delays and enjoy a smoother path to completion.
