Why Melbourne residential projects take longer than you expect — and how to plan for it

Ask most people how long a residential project takes and they'll say six months. The reality, for a custom home or significant renovation in Melbourne, is closer to two to three years from first conversation to handover. Understanding why — and planning for it — makes the difference between a project that runs smoothly and one that feels like it's constantly behind.

The design phase

A thorough design process takes time. Concept design, design development, and the preparation of documentation for a planning permit application typically run three to six months for a custom residential project. Rushing this phase to get to construction faster is one of the most common and costly mistakes clients make — problems that aren't resolved on paper are resolved on site, at significantly higher cost.

Planning permit

Not every project requires a planning permit, but many do. Once lodged, a straightforward application with no objections might be determined in two to three months. Applications that are advertised to neighbours, referred to other authorities, or subject to objections can take six to twelve months or longer. Heritage overlays, vegetation overlays, and neighbourhood character considerations all add complexity and time.

The Metropolitan Planning Levy must be paid before certain applications can be lodged — an administrative step that catches clients off-guard if it isn't anticipated.

Building permit and documentation

After planning approval, working drawings and engineering documentation are prepared for a building permit. This phase typically takes two to four months. Building permits are issued by a private building surveyor and must be in place before construction commences.

Construction

A custom home typically takes nine to fourteen months to build, depending on size, complexity, and site conditions. Sloping sites, difficult access, and bespoke materials all extend the program. Weather delays, trade availability, and product lead times — particularly for imported materials — are real factors in Melbourne's construction environment.

The honest timeline

From first conversation to handover, budget two to three years for a custom home with a planning permit requirement. For a straightforward extension without planning, twelve to eighteen months is realistic.

We map the full timeline at the start of every project — including likely permit timeframes, construction program, and the decisions that need to be made at each stage. No surprises.
