Latest read (June 2026): Victoria's official ABS average is $1,914/m² ($485,292 for a completed home, 2024-25). Melbourne construction costs rose +0.9% in the June 2026 quarter (Cordell/Cotality), and nationally new-dwelling prices are up 5.8% over the year, so forward budgets should sit above the older completion average.

Base build (contract sum)
The base build is the headline figure a Melbourne builder quotes: the home design at standard inclusions, sitting on a standard slab, on a level standard block. It is the number in the advertisement. It is almost never the number you actually pay.
What "standard inclusions" means varies enormously between builders. Ask any Melbourne builder for their standard inclusions list in writing - a responsible builder will hand you a multi-page document, a bad one will hand-wave. Compare inclusions before comparing prices.
Site costs
Site costs are the works needed to make a specific block build-ready: extra footings or groundwork on reactive clay, retaining walls where the block slopes, cut-and-fill on uneven blocks, temporary fencing, waste removal. In Melbourne's growth corridors, reactive clay often means a more heavily engineered slab, which can add thousands of dollars, so your soil test and engineer confirm what your block actually needs.
Site costs are almost always quoted as PROVISIONAL at tender. The final number is set once a soil test, contour survey and connection quotes are in hand. Ask your builder to show you the provisional cap on their contract, what would push it above cap, and how they reconcile.
Provisional sums (PC items)
A provisional sum is an allowance for a specific item where the exact spec is not yet known - typically tiling, taps, appliance selections, floor coverings. The builder allows a dollar amount; you pick the specific product; the difference is reconciled at construction stage.
The trap: some builders allow provisional sums that are unrealistically low, so the base build looks cheap. Reconciliation then pushes the final invoice up. Compare the PC allowances across builders on your shortlist, not just the base build.
Statutory levies (Melbourne-specific)
Victoria has statutory levies that do not exist in every state. The three most commonly relevant to a Melbourne buyer: the Growth Areas Infrastructure Contribution (GAIC) on qualifying land in growth areas; a Section 173 agreement fee where the developer has attached one to the parent title; the foreign purchaser additional duty for non-resident buyers.
Each of these is administered by the State Revenue Office, and each is capped or triggered on specific conditions - your conveyancer will confirm which apply to your specific parcel before you sign.
Connections and utilities
Every new Melbourne home needs power, water, sewer, stormwater and NBN connections. In greenfield estates these are usually pre-run to the lot boundary; the cost is the drop from boundary to home. In infill (KDR) blocks the connections may need to be replaced entirely - an easy way to add tens of thousands to the total.
Ask your builder for a written connection allowance and confirm with a Melbourne services locator like Before You Dig Australia what is actually at your boundary.

Cost to build a house in Melbourne by build tier (2026)
Quick answer
For a standard 200 m² home in Melbourne, base build runs from about $380,000 for a budget volume home to $1.04M+ for a high-end custom build, roughly $1,900 to $5,200+ per square metre, excluding land. The official ABS average for Victoria is $1,914/m².
| Build tier | Cost per m² | Est. total build (200 m² home) |
|---|---|---|
| Budget / Basic – Volume project home | $1,900 - $2,700 | $380,000 - $540,000 |
| Mid-Range – Upgraded finishes | $2,700 - $3,600 | $540,000 - $720,000 |
| High-End / Custom – Bespoke design | $3,600 - $5,200 | $720,000 - $1.04M |
| Luxury – Architectural design | $5,200 - $6,900+ | $1.04M - $1.38M+ |
Victoria also carries GAIC in growth areas and 7-star NatHERS requirements. These are base-build ranges. Add roughly 25–45% for land, site works (slope, soil, retaining), professional fees and GST to reach a total project budget. Always treat a builder’s fixed-price contract as final — per-m² rates are for planning only.

Watch full episodeFrequently asked
What is included in "base build" in Melbourne?+
The specific design at the builder's standard inclusions on a standard slab on a level standard block. It excludes site costs, provisional sums, statutory levies, connections and any spec upgrades. Always request the "standard inclusions" list before comparing base builds.
How much do site costs usually add in Melbourne?+
Site costs commonly land in the mid-five figures for a standard block in a Melbourne growth corridor, and much higher on slope, reactive clay or narrow-frontage lots. Because they are provisional, any builder promising a "fixed site cost" without a soil test is misleading.
Is GAIC always payable in a growth corridor?+
Not always. GAIC applies to certain parcels in growth areas when first developed or subdivided. The parent title's history determines whether the levy has already been paid or is still triggered. Your conveyancer will run a state check on the parcel.
How do I compare Melbourne builder quotes fairly?+
Line up base build, site cost cap, PC allowances (tile, taps, appliances, flooring), statutory levy allowance, connections, and any inclusions that need upgrading to match. If a builder will not itemise on paper, they are not comparable.
Where does BuildPilot get Melbourne cost figures?+
Live H&L feed for headline pricing, State Revenue Office for statutory figures, VBA for regulatory context, and partner builders for actual line-item pricing. All external, all cited on the page.
