If you're comparing volume builders in Melbourne with a custom builder, you're really comparing two different ways of getting a house built. They aren't a good one and a bad one. Each suits a different kind of project, and the price on the front page won't tell you which is which.
The short version. A volume builder sells a catalogue of repeatable designs, priced to build quickly at scale. A custom builder designs and builds around your block and your brief. Volume tends to win on a simple site and a fixed idea of what you want. Custom tends to win when the site is difficult, the design matters, or you want to understand every line of your price.
How each one works
| Volume builder | Custom builder | |
|---|---|---|
| Design | Pick from a range of standard plans, with options | Designed for your block and brief, or built to your own architect's plans |
| Pricing | Headline price on a standard facade and inclusions list | Priced to the plans and specification, once the site is known |
| Site costs | Often priced separately or added after soil and survey | Allowed for in the design and the contract |
| Changes | Limited and charged as variations | Built into the process |
| Best on | Flat, simple, vacant or cleared blocks | Knockdown rebuilds, slopes, narrow or odd blocks, overlays |
Where the price gap comes from
A headline price is only comparable to another headline price if they include the same things. Ask each builder, in writing, what is in and what isn't: site costs, retaining, driveway and crossover, landscaping, fencing, window coverings, and the council and authority fees that sit outside the contract. The gap often closes, or reverses, once you compare the whole project. Our guide to the hidden costs of a knockdown rebuild lists what to look for.
Design freedom, and what it costs
Customisation is where the cost sits, in either model. A volume builder keeps cost down by keeping the design repeatable, so changes become variations. A custom builder gives you the freedom, but that freedom is a cost if you spend it everywhere. The sensible approach is to spend it where it counts. We've written about that in Custom Where It Counts.
Where Crowncon sits
We're a custom builder, and we try to take the guesswork out of it. Our designs come in three series. Considered is a curated range of designs, which gives you pricing clarity early. Bespoke is designed with you for your block. Realisation is for owners who already have plans and want them built well. That gives you a way in whichever end of the spectrum you're at.
When a volume builder is the right call
Plenty of people are well served by a volume builder, and we'd tell you so. It can suit you if the block is flat and cleared, you're happy with a standard plan, you want a quick path to a fixed outcome, and you understand what the headline price leaves out. If your site is complicated, you're rebuilding on an existing block, you care about the design, or you want one team from concept to keys, custom is usually the better fit.
Five questions to ask any builder
1. Is the price fixed, and what are the prime cost items and provisional sums? 2. What are the site costs, and are they in the contract? 3. What is excluded, in writing? 4. How are variations priced? 5. Is the builder registered, and can you see the domestic building insurance before you pay a deposit?
On the last one, Consumer Affairs Victoria says the deposit on a contract of $20,000 or more is capped at 5 per cent, and for work over $16,000 you should see evidence of domestic building insurance before paying a deposit.
Common questions
What is the difference between a custom builder and a volume builder?
A volume builder offers a catalogue of repeatable designs priced for building at scale. A custom builder designs and builds around your block and brief. Volume suits simple sites and fixed expectations. Custom suits knockdown rebuilds, difficult sites and design-led projects.
Is a volume builder cheaper than a custom builder?
The headline price often is. But headline prices rarely include site costs, landscaping, driveway, fencing or fees, so compare the whole project, not the first number.
Can I get a custom home without a fully bespoke price?
Yes. A curated design range gives you pricing clarity early. Crowncon's Considered series works this way, with Bespoke and Realisation for projects that need more or arrive with plans.
How much deposit can a builder ask for in Victoria?
For domestic building contracts of $20,000 or more, the deposit is capped at 5 per cent of the contract price. For work over $16,000, you should see evidence of domestic building insurance before paying any deposit.
