Summary
Preliminarily feasible · CDC with conditions
2 designs fit with conditions; recommended: COOGEE (30 m² · 1 bed)
Key reasons
- C7 Rear setback: Rear setback 3.49m is less than the required 6.60m; fails only because of the height addition — met if the design is ≤ 3.8 m tall
- E2 Distance to the house: 0.76m from the house, under 1.80m — fire-rated wall needed
Not checked: A2 Restrictions on title (88B) · B7 Other CDC exclusions · B8 Mine subsidence · B9 10.7 complying development statement · C10 Living-room window setback · E6 Easements · E7 Sewer main · E8 Manholes and connection points · E9 Stormwater · E10 Reticulated sewer · E11 Delivery and crane access
17 pending review · 11 estimated
This is a preliminary assessment from public data — upload documents for a full assessment
Next steps
