Did You Know: You Could Build a Granny Flat and Studio on One Block?

If your lot is over 450m², NSW’s complying development rules allow you to build:

A 60m² granny flat, and
A 36m² studio, as long as they’re *ancillary to your main home.
*In simple terms, that means your property must already have a house on it.

At Five Star Builders, we handle the full process under complying development controls. So there’s absolutely no lengthy council approval needed.

It’s a smart way to maximise usable space, boost value, and future-proof your property.

All in one efficient project!

Can I Actually Build a Granny Flat in My Backyard?

Good question — and one we hear a lot. The short answer? It depends on a few key things. But don’t worry, we’ll break it down.

Here’s a quick cheat sheet for what most Sydney blocks need:

Land size: At least 450 square metres
Frontage: 12 metres wide from the front of your existing home
Setbacks: You’ll need 3 metres from the rear fence, and 0.9 metres from the sides
Trees: Any tree taller than 6 metres? You’ll need to keep at least 3 metres clear

That said, ticking those boxes is just the start. We also look at things like slope, drainage, access for machinery, existing services (water, power, sewer), and whether your property falls under bushfire or flood zoning. It’s the stuff that isn’t obvious that tends to cause the biggest headaches later — if it’s not picked up early.

That’s Where Our Free Site Inspection Comes In.

Instead of guessing or hoping your block will qualify, let us come take a look. Our team at 5 Star Granny Flats has spent over 15 years walking backyards across Sydney, figuring out what’s possible — and how to make it happen.

We’ll assess your site properly, talk you through the rules, and let you know whether your build can be approved under the fast-track Complying Development route, or if it needs a full DA (and what that actually means for your timeline).

You’ll get clear, honest advice, not a sales pitch — and you won’t be left with surprises mid-build. We’ve seen just about every type of site you can imagine, so if there’s a smarter way to approach your project, we’ll tell you.

by Past Clients

We started our build in October 2021 and we have successfully received a beautiful home for my mum to move into. Within these 7 months, every step of the way, each team member of five star builders held our hand and guided us through every step of the way. Tony helped us greatly in all aspects of admin and council dealings and spent time getting to us know as well. Sarkis and Anthony are super helpful, friendly and I found them professional yet personable at the same time. We were very impressed by the builders using “old school” techniques and actually building our granny flat using skill and brains, rather than precast ready made stuff. Mannan who overseas all the trades staff was here every morning at making sure deadlines were being met and work performed was to our satisfaction. I have no problem in recommending the team at Five Star Builders to anyone that needs a Granny Flat. Well done team. Another happy customer ticked off your list.

Testimonial

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. He was extremely knowledgeable and honest with Council requirements and transparent with pricing. Once we deposited everyone on the team was great to deal with. Very patient, polite and detailed. Construction went really well considering we were building through Covid and the Team pushed hard to get through the build as quickly as possible. We are so impressed with the quality and how it looks and it was easy to obtain a tenant in the end. We look forward to our next project with 5 Star Builders. Highly recommended.

Testimonial

5 Star Granny Flat had done an tremendous job with our granny flat, am extremely happy with out granny flat. Sakis and Sarif we’re on top of the job all the time, they made sure everything was completed on time and ran smooth. Nicola and Toni did a great job with answering all my questions and were efficient with all paper works and explaining things to me. I love the fact that I didn’t have to do anything whereas they did it all for me. With the prices going up 5 Star kept to their word and did not change the prices, when they ran out of stock they contacted me straight away with an alternative. A big thank you to Scott for taking us on board. I would recommend 5 Star Builders 100%. Thank you team.

Testimonial

We built our granny flat with 5 Star Granny Flat builders. We are very happy with the entire process dealing with them. Construction completed on time and within the initial agreed budget. Specially, the field supervisor Sam, he is always available for suggestions and questions. Sam is very knowledgeable and helpful throughout the construction period. Sarkis was providing the necessary guidance incase of any issues. He is always reachable. Also, Office team (Tony) was very supportive and he was very quick in responding to all the emails. Overall we are very happy with the outcome, we highly recommend this builder.
