How Much Does It Cost to Build a Custom Home in Geelong in 2025?
If you’re thinking about building a custom home in Geelong this year, one of the first big questions is cost. It’s a fair question and one that doesn’t always come with a simple answer.
At Derbyshire, we design and build homes across Geelong, the Surf Coast, and the Bellarine Peninsula, so we understand how much location, site conditions, and design choices can impact your budget.
In this post, we’ll walk you through the key factors that affect the cost of a custom build, give you some realistic 2025 estimates, and share how we help stretch your budget further without compromising on quality.
What Affects the Cost of a Custom Home in Geelong?
No two custom homes are the same, and that’s exactly the point. But it also means costs can vary quite a bit. Some of the biggest factors include:
- Site conditions: Is your block flat or sloping? Easy access or slightly awkward? Sloping blocks, limited access, and excavation needs can all affect pricing.
- Size and layout: Naturally, a four-bedroom home with multiple living zones and a pool will cost more than a more traditional, single-storey design.
- Level of finish: Your choice of joinery, flooring, windows, cladding, kitchen specs, and bathroom fittings all influence your final cost.
- Energy efficiency and sustainability: Thinking about hydronic heating, solar, or passive design principles? These features offer long-term benefits, but they do add to the overall cost of the build.
- Knockdown rebuild vs new land: Demolition, site prep, and neighbourhood overlays can all affect the cost if you’re knocking down an existing house.
Custom Home Build Costs in Geelong for 2025
According to reports from the start of 2025, custom home builds in Geelong range anywhere from $625,000 to $1.2 million+, depending on the scope, site, and specifications. That wide range reflects just how personal and varied custom homes can be. If you’re after something architecturally designed, built on a more complex block, or fitted out to a high spec, it can move into the higher end of that range (and sometimes beyond).
A good builder will help you get the most out of your budget without compromising on quality. Here are some of the ways we do that for our clients.
We know that budget matters and we’re upfront about what’s possible within it. At Derbyshire, we work closely with you from the design stage to:
- Design within your brief and budget.
- Help you understand where to invest and where to save
- Make smart design decisions that give you value without compromising quality
- Offer transparent pricing early, so you can make informed decisions.
Every site and every brief is different, so we take the time to map out your costs early and clearly. It’s all about building trust, as well as a home you love. This means that it usually takes multiple meetings to figure out what will be included in your custom home. When the costs are broken down it makes it easier to figure out what is worth spending the money on and what is worth finding a different solution for.
