Duplex DA Approval Sydney, Council-Ready Plans, Reports & Design Strategy
A Development Application is a merit assessment, council weighs your duplex against the LEP and DCP and the impact on neighbours and streetscape. Winning a DA is about anticipating those questions in the design and answering them clearly in the documentation. That's what we prepare.

When a DA is the right path
A DA suits sites that don't fully meet CDC standards, sit within a heritage or overlay area, or benefit from design merit and flexibility. It's slower than CDC but far more forgiving of the real-world quirks of Sydney blocks.
What council assesses
Compliance with the LEP and DCP (and any relevant SEPP).
Streetscape, bulk, scale and articulation.
Privacy, overlooking and overshadowing (shadow diagrams).
Parking, access and stormwater.
Neighbourhood and amenity impact.
What we prepare and coordinate
Architectural plans and elevations to lodgement standard.
Consultant brief and coordination (surveyor, stormwater, and any specialists your overlays require).
Statement of Environmental Effects (SEE) coordination.
Shadow diagrams and BASIX/NatHERS coordination.
RFI responses and revised plans if council requests further information.
Questions about da approval
An RFI (request for information) is council asking for clarification or changes during assessment. It's common and not a refusal. A well-prepared application reduces the likelihood and severity of RFIs, and we respond to them promptly with revised documentation.
It varies by council, submission quality and whether an RFI is issued, typically several months. Our cost & timeline guide gives honest ranges.
