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.
Not always, shared or tandem access can free up frontage. We work the parking and access into the design from the start.
