Before Structuring a Sydney Duplex Development: Seven Questions to Ask

A strong duplex opportunity is created before purchase, not after. The site, planning pathway and market evidence should be tested before major commitments are made.

1. What planning pathway is realistically available?
2. Does the site support the proposed dwelling mix, parking, landscaping and private open space?
3. Are there constraints from trees, slope, access, easements or neighbouring context?
4. What comparable sales support the finished product?
5. How sensitive is the feasibility to construction cost escalation?
6. What approval, holding and exit timing assumptions are being used?
7. Which professionals will verify legal, tax, planning, QS and construction inputs?

The answer to each question should be documented. If a scenario depends on optimistic assumptions across all seven, the risk is usually being underpriced.
