How to Analyse a Development Site Before You Buy

The early checks that help you separate genuine development potential from an expensive assumption.

Council planning map, site plan and development checklist

The asking price is only one part of a development site. The real opportunity sits in what can be approved, built, financed and sold—or held—after every material constraint is considered.

Read the planning context

Check zoning, overlays, minimum lot sizes, height, density, setbacks, parking, heritage, vegetation and flood or bushfire constraints. Council mapping is a starting point, not a substitute for professional advice.

Read the physical site

Frontage, access, slope, orientation, easements, services, neighbouring conditions and likely civil works can materially change both design and cost.

  • Confirm title and easements
  • Inspect service locations and capacity
  • Allow for demolition, retaining, drainage and access

Test the market and feasibility

Base end values on relevant evidence and include acquisition, consultants, authority charges, finance, construction, sales, tax and holding costs. Then stress-test the assumptions that have the biggest effect on the result.
