Why frontage matters so much
A side-by-side duplex needs enough width for two dwellings, two driveways or a shared access, setbacks and articulation. Squeeze that too tight and you lose parking, privacy and streetscape quality: the very things assessors scrutinise.
Design responses for narrow frontages
- Rethinking the configuration, front-and-rear or a detached dual occupancy instead of side-by-side.
- Shared or tandem driveways to reclaim frontage for the building.
- Careful window and balcony placement to manage privacy on tight side setbacks.
- Section design that borrows light from above where the plan is constrained.
CDC vs DA on narrow blocks
Under 12m frontage usually rules out the CDC fast-track, pointing to a DA where design merit can carry the day. That's not a downside, it's often where a considered design outperforms a boxy compliant one.
Frequently asked questions
Often yes, via a DA. Under 12m generally rules out CDC, but a well-designed side-by-side or an alternative configuration can still work. It depends on the depth, the controls and the design.
