The Perth
Build-Cost Index.
The same new home costs up to $16,471 more to build in one Perth suburb than another, before you buy a square metre of land. The Property Plug Build-Cost Index 2026 publishes the real siteworks for 102 Perth suburbs, from $20,636 to $37,107, and the indicative all-in build cost that follows. Land is excluded throughout, on purpose, so you see the true cost of the build.
Where you build moves the price before land does
Atwell, Aubin Grove, Aveley, Banjup, Beechboro carry the lowest siteworks in the index, about $20,636. The same entry home lands around $329,854 all-in, before land.
Bullsbrook, Swan View, Ravenswood, Middle Swan, Maddington reach about $37,107 in siteworks. The identical entry home runs near $346,325 all-in, before land.
Half of Perth's costed suburbs sit at or below $23,056 in siteworks. It is the honest middle most buyers should plan around.
95 of 102 suburbs keep an entry new home under $340,000 all-in for the build, excluding land. Affordable build stock is not gone, it has moved.
IndicativeEstimate only, not a quote or an offer. Figures combine a home design starting price with the suburb siteworks and do not include land. Designs, builders, land and pricing change and are subject to availability. We confirm a fixed price with your matched builder on enquiry.
How the index is built
The siteworks figures are real, costed across The Property Plug's verified builder panel for 102 Perth suburbs and growth corridors. They are not modelled estimates. Siteworks cover the work that gets a block ready for a slab: site survey and soil classification, earthworks and fill, retaining, drainage, a sand pad where needed, piering on reactive soils, and service connections.
The all-in build figure is indicative. It combines a current entry home design starting price ($309,218) with each suburb's siteworks. It excludes land, which is bought separately and varies far more than the build. A typical 4x2 starts higher, from $314,760 before siteworks. Final pricing depends on your exact block, design and selections, and is confirmed with your matched builder on enquiry.
- What it includes: build cost only, design starting price plus suburb siteworks.
- What it excludes: land, stamp duty, finance costs, and post-handover landscaping or upgrades.

How much does it cost to build a house in Perth in 2026?
An entry new home in Perth starts from $309,218 for the build, before siteworks and land. Once you add a suburb's real siteworks, the indicative all-in build (still excluding land) ranges from about $329,854 in the cheapest-to-build suburbs to about $346,325 in the most expensive. The single biggest variable between suburbs is siteworks, which swings $16,471 across the 102 suburbs in this index.
What are siteworks and why do they change by suburb?
Siteworks are the costs of preparing your block so the slab can go down: site survey and soil classification, earthworks and fill, retaining, drainage, sand pad, piering on reactive soils, and connections. They vary suburb to suburb because soil type, slope, fill depth, wind region and bushfire rating change. Two identical homes on two different blocks can differ by tens of thousands before a single brick is laid, which is exactly what this index measures.
Which Perth suburbs are cheapest to build in?
On siteworks, the lowest-cost suburbs in this 2026 index are Atwell, Aubin Grove, Aveley, Banjup, Beechboro, each around $20,636 in siteworks. That makes them the cheapest places to build the same home, before land. The most expensive are Bullsbrook, Swan View, Ravenswood, Middle Swan, Maddington, where siteworks reach about $37,107.
Do these figures include land?
No. Every figure in this index is the build only: a home design starting price plus the suburb siteworks. Land is bought separately and varies far more than the build. We keep them separate so you can see the true build cost honestly, then add your land budget on top.
How accurate is the Perth Build-Cost Index?
The siteworks figures are real, costed across our verified builder panel for 102 Perth suburbs, not estimates. The all-in build figures are indicative: they combine a current design starting price with the suburb siteworks and exclude land. Your final number depends on your exact block, design and selections, and we confirm a fixed price with your matched builder on enquiry.
