Duplex Architect Blacktown, Dual Occupancy Design & Approvals
Blacktown City is one of Sydney's fastest-growing LGAs, with strong investor demand for dual occupancy. Many regular lots suit a straightforward duplex, but the Blacktown LEP/DCP and, in newer estates, precinct controls still apply. We design duplexes that maximise yield and clear assessment cleanly.

Blacktown planning notes for dual occupancy
- Blacktown has large tracts of regular R2 lots well suited to side-by-side dual occupancy, often good CDC candidates where the 450m²/12m and overlay tests are met.
- Newer release areas may carry precinct or growth-centre controls that override the standard LEP, we confirm which apply.
- Overland flow and drainage need attention on some flatter estates; stormwater design is key.
For Blacktown estates we confirm whether precinct controls apply, then test CDC eligibility, many of these lots are genuine fast-track candidates.
