Granny Flat Prices Sydney
Every price on this page is an indicative starting price for that design. After your free site inspection, we give you a detailed, transparent quote with no hidden costs and no surprises.
Prices start from $138,000 for a studio and range to $245,000 for a premium 2-bedroom. The final price depends on the design, your site conditions, and the finishes you choose. Most of our builds are approved through a Complying Development Certificate (CDC), which is faster than a full Development Application, and we back approvals with our 4-week approval guarantee. If your block needs a DA instead, we manage that too.
Clear pricing across our full range
We build studios, 1-bedroom, 2-bedroom, and 3-bedroom granny flats across Sydney. Every design has a published starting price, and once we inspect your site you receive a detailed, transparent quote. No hidden costs, no surprises.
The price difference between bedroom types is mostly driven by floor area and build complexity. A studio at 35m² costs less than a 2-bedroom at 60m² because it uses less material and less labour. Below you will find the starting price for every bedroom type, with links to full pricing detail for each.

What affects the final price
Every build is different. Here is what moves the number.
Design size and floor area
Larger floor plans cost more. A studio at 35m² and a 3-bedroom at 82m² use different amounts of material, labour, and time. Every design on our website shows its indicative starting price as the baseline before site factors are applied.
Your site and access
Slope, soil type, drainage, machinery access and existing services all affect cost. That is why we do a free site inspection before we quote, so you know the full picture before you commit to anything.
Finishes and extras
Our standard inclusions suit rental and resale. Mid-range or premium finishes, such as stone benchtops and designer selections, and extras like a deck, carport or solar panels are priced separately.
CDC vs DA: what it means for your budget
Most granny flats in NSW need either a Complying Development Certificate (CDC) or a Development Application (DA). A CDC is approved by a private certifier against set rules, which makes it faster than a full DA assessed by council. Our designs are planned to meet the CDC rules wherever possible, and we back approvals with our 4-week approval guarantee. If your block sits outside the standard rules, a DA applies and we manage that on your behalf.
| Feature | CDC | DA |
|---|---|---|
| Approved by | Private certifier | Your local council |
| Speed | Faster, set rules | Slower, full assessment |
| Managed by us | Yes | Yes |
Frequently asked questions
How much does a granny flat cost in Sydney?
Our granny flat prices start from $138,000 for a studio and go up to $245,000 for a premium 2-bedroom design. The final price depends on the design you choose, your site conditions, and your finishes. We give you a detailed, transparent quote after your free site inspection.
Is the price on your website the final price?
The prices shown are indicative starting prices for each design. After your free site inspection, we provide a detailed, transparent quote with no hidden costs and no surprises. If you decide to move forward, a design fee applies, which covers a contour survey, floor plans and elevation drawings.
Do you handle the approval?
Yes. We manage the approval end to end, through a CDC wherever possible or a DA if your block needs one, and we back approvals with our 4-week approval guarantee.
How long does a granny flat take to build?
Generally it takes 14 to 16 weeks for your granny flat to be built after the initial site setup, and most projects are completed within 12 to 20 weeks from approval. We give you a clear schedule before work starts.
Can I get finance for a granny flat?
Many homeowners fund a granny flat through their bank or mortgage broker, often using equity in their existing home. We recommend speaking with your lender before your site inspection so you know your budget going in.

No complicated tender process. A designer comes back to you within one business day of your enquiry.

Questions we hear before every build
“I don’t know if my block qualifies”
Most granny flats need a block of at least 450m² with a 12m frontage. Odd-shaped blocks, sloping land, and tight sites are all things we assess. The fastest way to find out is a free site inspection, or a quick eligibility check with Stella.
“I’m worried the final price will be higher”
That’s exactly why we inspect your site before we quote. You receive a detailed, transparent quote with no hidden costs. If site conditions are complicated, such as slope or tight access, we flag it before you commit, not after.
“Will it add value to my property?”
Every property is different, but a compliant granny flat typically adds $150,000 to $250,000 to a Sydney property’s market value, while also earning rental income. A studio from $138,000 renting at $400 per week would return its build cost in under 7 years from rent alone.
“How disruptive is the build?”
We show up when we say we will and give proper notice before disruptive stages. Most of the build happens in your backyard while you continue living in the main home, and we keep you in the loop throughout.
What Sydney homeowners say about building with us
4.9 stars across 200+ verified Google reviews
We started our build in October 2021 and we have successfully received a beautiful home for my mum to move into. Every step of the way, each team member of Five Star Builders held our hand and guided us. Tony helped us greatly in all aspects of admin and council dealings. Sarkis and Anthony are super helpful, friendly and professional yet personable. We were very impressed by the builders using "old school" techniques, building our granny flat using skill and brains. I have no problem recommending the team at Five Star Builders to anyone that needs a granny flat.
Lisa O'Connor Verified Google review I met 5 Star Builders through a referral and they were fantastic throughout the whole process. We built a granny flat on the Central Coast and met Zahi onsite for an inspection, extremely knowledgeable, honest with council requirements and transparent with pricing. Construction went really well and the team pushed hard to get through the build as quickly as possible. We are so impressed with the quality, and it was easy to obtain a tenant in the end. Highly recommended.
Lise B Verified Google review I can't thank Samantha enough for introducing me to 5 Star Builders. Recently they completed my granny flat. What a job… Thank you Sarkis, thank you Anthony and thank you office staff. Very happy customer, best service, honest, and very professional. 10 stars for a job well done. I highly recommend 5 Star Builders. Stand by guys for my next project.
George Issa Verified Google review 5 Star Granny Flats did a tremendous job with our granny flat, I am extremely happy. Sarkis and Sharif were on top of the job all the time; they made sure everything was completed on time and ran smooth. Nicola and Tony did a great job answering all my questions and were efficient with all paperwork. With prices going up, 5 Star kept to their word and did not change the prices. I would recommend 5 Star Builders 100%.
Neomai Miko Verified Google review We built our granny flat with 5 Star Granny Flat builders. We are very happy with the entire process, construction completed on time and within the initial agreed budget. The field supervisor Sam is always available for suggestions and questions, very knowledgeable and helpful throughout. The office team was very supportive and quick in responding to all emails. Overall we are very happy with the outcome; we highly recommend this builder.
