Before relying on a listing’s “development potential”, establish which rights exist, what your intended project needs and which questions remain unresolved. Do this while there is still time to investigate the property and negotiate appropriate contract protections with your solicitor or conveyancer.
Match the property to your project
Write a brief stating the intended use, approximate scale and whether the objective is rental income, separate titles, redevelopment or sale with approvals. Compare properties against the same brief. A cheap site can still be unsuitable if the project relies on an uncertain change in rights or expensive services.
Ask for the evidence behind the description
- Current zoning information and applicable zoning-scheme provisions and spatial policies.
- Title information and restrictive conditions and servitudes requiring legal review.
- Decision notices or approval letters, approved plans, amendments and conditions.
- Available approved building plans and the lawful-use history of existing structures.
- Information about access, drainage, water, sewer and electricity connections and capacity.
Classify each claim as documented, requiring verification, or dependent on a future application. “Previously discussed with council” is different from an approval. An approval for an earlier layout is different from permission for the design you intend to build.
Use a simple purchase-risk checklist
| Question | Why it matters |
|---|---|
| Does the intended use fit the planning controls? | A different or more intensive use can require assessment even where the building already exists. |
| Can the site accommodate a functional layout? | Parking, access, slope and existing structures can undermine a theoretical yield. |
| Are approvals current and usable? | Conditions, remaining validity and further permissions can affect implementation. |
| What costs remain uncertain? | Infrastructure, technical reports and holding time can change feasibility. |
| What is the fallback? | Understand what can lawfully continue if the intended application is refused or delayed. |
Separate planning advice from the other investigations
A planning review should identify which matters need a surveyor, engineer, environmental or heritage specialist, building professional or certifier. Your solicitor or conveyancer should review ownership, legal restrictions and the contract. Obtain separate valuation, cost, finance and tax advice where required. Agree a scope so important matters are not assumed to be covered by someone else.
Resolve the major uncertainties before committing
Illustrative example: a site is advertised for three dwellings, but the available information only confirms the current house. Before treating three units as the purchase basis, test the layout and approval pathway, obtain targeted servicing advice and price the unresolved work. Ask your legal adviser whether conditions and adequate investigation periods can be negotiated; a planning opinion is not an approval or a substitute for contract advice.
A written planning assessment against your intended project, a list of missing evidence and the issues most likely to change the decision. Send the address, property reference, listing, available documents and a short development brief.
