Granny flats in Woollahra — common questions
Can I build a granny flat in Woollahra?
Woollahra is challenging for granny flat eligibility. With 761 heritage items and many lots under 450 m² in Paddington and Double Bay, a large proportion of properties are ineligible via CDC. Check your address above — larger detached homes in Woollahra and Bellevue Hill have better prospects.
Why are many Woollahra properties ineligible for a granny flat?
Two main reasons: heritage (conservation areas cover most of Paddington and parts of Woollahra village) and lot size (Paddington terrace lots are typically 100–250 m²). Either exclusion alone is enough to block the CDC pathway.
Can I build a granny flat on a Paddington terrace?
Almost certainly not via CDC — Paddington lots are typically well under 450 m² and heritage-listed. A DA is theoretically possible but would require heritage impact assessment and council approval, and may still face DCP restrictions.
What lot size is needed for a granny flat in Woollahra?
The minimum is 450 m². Larger detached homes in Bellevue Hill, Rose Bay, and parts of Woollahra on bigger blocks have the best prospects. Even these should be checked for heritage conservation area status.
Do I need council approval for a granny flat in Woollahra?
If the rare combination of sufficient lot size and no heritage exclusion is confirmed, a CDC through a private certifier is possible. More commonly in Woollahra, a DA through Woollahra Municipal Council is required.
