About this category
3 60m² granny flat designs designs.
60m² is the maximum internal floor area permitted for a granny flat under the NSW Complying Development Certificate (CDC) fast-track pathway. Every design in this collection uses that full 60m² footprint to deliver a genuine 2-bedroom secondary dwelling — two proper bedrooms, full bathroom, dedicated laundry and open-plan living.
Building to the 60m² cap keeps you eligible for CDC approval (as little as 10 business days via private certifier) rather than DA approval (3–6 months via council). For most granny flat projects, the speed and certainty of the CDC pathway make this the right choice.

Frequently asked
60m² Granny Flat Designs questions.
Why is the granny flat maximum 60m²?
60m² is the internal floor area cap set by the NSW State Environmental Planning Policy (Housing) 2021 for secondary dwellings that qualify for the CDC fast-track pathway. Above 60m² requires the slower DA pathway with council.
What can you fit in a 60m² granny flat?
Two proper bedrooms (both with wardrobes), a full bathroom, dedicated laundry, open-plan kitchen and living zone, and depending on layout an ensuite off the master. Attached carports and covered patios don't count toward the 60m² cap.
How long does CDC approval take for a 60m² granny flat?
As little as 10 business days once the CDC application is lodged with complete documentation. Design and documentation typically takes 4–8 weeks before lodgement.
