New homes
under $450,000.
The Property Plug lists 41 home designs that build for under $450,000 all-in, from $238,136. Each figure is the design base price plus Atwell's real siteworks of $20,636, so it is the landed build cost on a low-cost block. Land is purchased separately. We are paid by the builder, never by you.
Last updated June 2026. Computed against Atwell siteworks ($20,636). Land purchased separately. Higher-siteworks suburbs cost more.
This band ranks designs by an indicative build estimate, the home design starting price plus a low-siteworks suburb's siteworks, with land excluded. It is a guide only, not a package price. The same home costs more once siteworks rise, so treat these as the entry point, not a cap.
