Frequently Asked Questions
Get instant answers to the most common questions about building a granny flat in Sydney.
Can I build a granny flat on my block?
Most Sydney blocks can accommodate a granny flat, but specific requirements vary by council. We provide a free assessment to determine your block’s suitability, including setback requirements, site coverage limits, and height restrictions. Our experts know every Sydney council’s rules and can guide you through the process.
How long does the entire process take?
From council approval to completion, the typical timeline is 16-22 weeks total. This includes 6-8 weeks for council approval and 12-16 weeks for construction. We handle all approvals and keep you updated throughout the process. Our streamlined approach ensures faster delivery than most builders.
What's the total cost for a granny flat?
Costs vary by design and site conditions, but our 1-bedroom granny flats start from $170,000 (turnkey), and 2-bedroom from $190,000. This includes everything: design, approvals, construction, fixtures, and connections. We provide fixed-price contracts with no surprise costs.
Is it legal to rent out my granny flat?
Yes, it’s completely legal to rent out SEPP-compliant granny flats in NSW. We ensure all our builds meet State Environmental Planning Policy requirements, making them rental-ready from day one. You can earn rental income immediately upon completion.
