Why the design matters
Every plan reviewed against your block and the CDC pathway.
Kingstyle Homes designs and builds granny flats across Sydney and Western Sydney — from Kellyville, Castle Hill and Baulkham Hills through to Liverpool, Penrith and Blacktown. Each design is planned around the primary home, the block, the setbacks and the NSW granny flat rules that decide whether your project takes the fast-track CDC pathway (10 business days) or the slower DA pathway (3–6 months).
Whether you need a compact 1-bedroom retreat for a parent, a full 60m² 2-bedroom secondary dwelling for adult children or a two-storey design that preserves outdoor space on a tight block, the collection below covers the most common layouts we build across Sydney.

Frequently asked
NSW granny flat questions.
What is the maximum size for a granny flat in NSW?
60m² internal floor area under the CDC (fast-track) pathway. Larger secondary dwellings require Development Application (DA) pathway with council, which takes 3–6 months instead of 10 business days.
What is the minimum block size for a granny flat in Sydney?
450m² minimum block size for the CDC pathway in NSW. Blocks under 450m² require DA pathway with council, where policies vary by LGA.
How much does a granny flat cost to build in NSW?
Between $130,000 (studio) and $310,000+ (3-bedroom or two-storey), depending on size, finish level and site conditions. A typical 2-bedroom 60m² granny flat with mid-range finish costs $200,000–$250,000 turnkey.
How long does it take to build a granny flat?
Design and CDC approval: 6–10 weeks. Construction: 14–20 weeks depending on complexity. Total from initial briefing to handover: typically 5–8 months.
Can I rent out my granny flat in Sydney?
Yes. Once approved and constructed, a granny flat can be rented to anyone (family or non-family) under standard NSW tenancy law. A well-designed 60m² 2-bedroom granny flat in Western Sydney typically rents for $450–$650 per week.
