Why is the base price so different from the turn-key price?

A base contract covers the house as designed; turn-key adds the things you actually need to move in - site costs, driveway, landscaping, floor coverings, blinds, heating/cooling and fencing. In Melbourne that gap is commonly $50,000-$150,000, so only compare quotes on a like-for-like turn-key basis.

Are volume homes good quality?

They can be very good, but quality depends on the specification and the trades. Walk through recent completions (not just the display home), read the full inclusions list, and check the builder's VBA registration and recent reviews before signing.

How do I check a builder is registered and insured in Victoria?

Every residential builder in Victoria must be registered with the Victorian Building Authority (VBA) in the right class (e.g. Domestic Builder - Unlimited). You can verify a registration by name or number on the VBA's public 'Find a practitioner' register. On any domestic building contract over $16,000, the builder must also take out Domestic Building Insurance (DBI), issued through the VMIA, which covers you for incomplete or defective work if the builder dies, disappears or becomes insolvent (6 years structural, 2 years non-structural from completion). Ask for both the VBA registration number and the project-specific DBI certificate of currency before you sign.

Volume (or project) home builders offer a range of pre-designed floor plans built at scale across Melbourne's growth corridors. You choose a plan, a facade and from a set of inclusions. It's the most cost-effective and fastest path to a new home, especially on flat, serviced estate blocks - but the base price and the turn-key price can be very different.

What is a volume (project) builder?

A volume builder constructs many homes a year from a catalogue of proven designs. Buying power keeps prices down and standardised plans keep timelines predictable. You customise within a defined set of options and facades. It's ideal for standard blocks in Melbourne's growth areas like Tarneit, Clyde, Wollert and Werribee.

Benefits

Lowest cost per m² of any new-build path
Fixed-price contracts with clear inclusions
Faster, more predictable build timelines
Display homes you can walk through before deciding
Streamlined on serviced estate blocks
Well-suited to first-home buyers and investors

Considerations

Limited design flexibility within set plans
Base price often excludes significant turn-key items
Site costs can add $10,000-$30,000+ on tricky blocks
Upgrades and variations add up quickly
Less suited to sloping, narrow or heritage sites
Quality of inclusions varies - read the specification

Why are site costs different between builders?

In this episode we explain to you why site costs are so confusing and why they may vary from builder to builder. We explain the inclusions and exclusions, how builders price site costs and also help you understand the role an engineer plays in the process too. A short episode, but a valuable one so be sure to listen in.

Common Questions

The terms are used interchangeably in Victoria. Both build pre-designed homes at scale from a catalogue. Some 'project' builders allow a little more modification than large volume builders, but the model - proven plans, fixed pricing, display homes - is the same.
