What makes 5 Star Granny Flats a leading granny flat builder in Sydney?
5 Star Granny Flats specialises in the design and construction of high-quality granny flats in Sydney, offering personalised solutions and a commitment to excellence that sets us apart from other builders in the region.
How long does it take to build a granny flat?
Build times vary depending on the size and complexity of the design, but most granny flats are completed within 12–20 weeks from the time council approval is granted.
Do I need council approval for a granny flat in Sydney?
In most cases, yes. The majority of granny flats in NSW require either a Complying Development Certificate (CDC) or Development Application (DA). Our team handles all approvals on your behalf so you don't have to navigate the paperwork alone.
What does a granny flat cost?
Pricing depends on size, design, land conditions, and selected finishes. We offer free on-site consultations and no-obligation quotes so you get a clear, transparent breakdown before you commit to anything.
Can I rent out my granny flat?
Absolutely. Many of our clients build granny flats as investment properties. A well-positioned Sydney granny flat can generate strong rental income. Our team can advise on designs that maximise rental appeal.
