Duplex Architect Cumberland, Dual Occupancy Design & Approvals

Cumberland planning notes for dual occupancy

• Cumberland was formed from parts of the former Auburn, Holroyd and Parramatta councils, legacy controls can differ noticeably between suburbs.
• Lot sizes and frontages vary; some streets suit CDC while adjoining ones need a DA, we verify per address.
• Overland flow and local flooding affect parts of the Duck River and Prospect Creek catchments.

In Cumberland we always confirm the governing legacy LEP first, because it changes the lot minimums and setbacks that decide the duplex layout. We then test CDC eligibility against the current Code and map overland-flow risk near Duck River or Prospect Creek before concept design.
