Journal.
Plain-English guides on building brand new in Australia. For first-home buyers and investors who want the homework done.
The Property Plug Journal publishes independent, dollar-specific guides on building a brand-new home in Perth: build costs, siteworks, first-home grants, investment yield, narrow-lot design and knockdown rebuilds. Every guide is written by a named team member and updated with current 2026 figures.
The true cost to build by Perth suburb, 2026
Our original siteworks data across 102 Perth suburbs, set against a real design base price, to show the all-in number a buyer actually pays.
What is a building broker, and why use one?
How an independent broker compares the whole market, who pays the fee, and where it actually saves you money on a new build.
First Home Owner Grant WA, explained for 2026
The $10,000 grant, the stamp duty concession and the schemes that stack with it, and how each one changes a brand-new build.
House and land vs buying established
The real trade-offs beyond the sticker price: grants, depreciation, maintenance, timing and what each path costs over five years.
Granny flat investment in Perth: the yield maths
A worked dual-income example using a real granny flat base price, plus the WA 70m2 rentable rule investors need to know.
Choosing a narrow-lot design: four beds on a tight block
How frontage drives the floorplan, what 7.5m and 10.5m really allow, and how to read a narrow-lot from-price honestly.
Siteworks explained: what is missing from a "from" price
Why two builds with the same base price land at different totals, and the per-suburb siteworks figure that decides the gap.
Is a knockdown rebuild worth it in Perth?
When demolishing and rebuilding beats renovating or relocating, the cost bands involved, and which suburbs make the maths work.
