What affects your 1 bedroom price
Single vs two-storey
The Roselea and Foxwood are single-storey builds starting from $156,000 and $160,000. The Figtree is two-storey from $220,000. The higher price reflects structural complexity, not floor area: the Figtree and Roselea are both 60m².
Your site conditions
Flat blocks with good access cost least. Sloping land, poor drainage or tight access adds cost. We flag this before you commit, and your site inspection is free with no obligation to proceed.
Finishes and extras
Standard inclusions come with every build. Mid-range or premium finishes, and extras like a deck, carport or solar panels, are optional and quoted separately before you commit.
What does a 1 bedroom earn in rental income?
Our cost and ROI calculator puts the Sydney average for a 1 bedroom granny flat at around $400 to $480 per week, with higher-spec finishes lifting that further. Two-bathroom designs like the Foxwood and The One suit couples who each want their own bathroom.

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.

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%.
