What shapes Perth residential feasibility

Perth residential feasibilities often combine apartments with group dwellings on the same site, especially in middle ring locations under R-Codes. Land is generally less of the total cost stack than in the eastern capitals, so build cost and pre-sales clearance drive most outcomes.

WA development contributions, structure plan obligations, and headworks sit alongside the standard cost lines. Programme risk and pre-sale velocity are typically the binding constraints.

Popurise models each typology as its own revenue and cost line, with shared land and finance, so a combined scheme can be tested in one feasibility.

Common project types

What Perth residential development typically looks like

The typologies that account for most feasibility work in this market.

Apartments

Boutique and mid-rise residential buildings on inner and middle ring sites.

Group dwellings

Multi-unit dwellings on R-Code zoned sites, sold individually under strata.

Mixed apartment and group dwelling schemes

Combined schemes on larger sites with shared land and finance.

Townhouse projects

Townhouse and terrace schemes on R-Code zoned infill sites.

Assumptions and outputs

What to test, and what the model returns

The inputs that move outcomes in this market, and the outputs that matter to investment committees and capital partners.

Feasibility assumptions to test
  • Site area, R-Code, and achievable yield.
  • Mix of apartments and group dwellings, with separate pricing.
  • WA development contributions and headworks.
  • Build cost rate by typology.
  • Pre-sales requirement and settlement timing.
Outputs that matter
  • Residual land value, set against the asking price.
  • Profit on cost and development margin.
  • Equity IRR, peak equity, and equity multiple.
  • Monthly cash flow, with funding peak and finance limit.
  • Sensitivity to revenue, cost, and timing assumptions.
