Benefits of Building a Granny Flat in Melbourne
With Destin Constructions (est. 1991)
1) Keep your loved ones close (but not too close)
We all treasure family, and a Granny Flat is an ideal compromise between closeness and independence. They’re perfect for elderly parents, retirees looking to downsize, newlywed couples trying to save money, small families, or singles seeking their own space.
2) Earn passive income (subject to Victorian rules & approvals)
Victoria’s “small second home” rules now allow secondary dwellings to be used by anyone, not just dependants, and many sites no longer require a planning permit, although a building permit and compliance still apply. That means your granny flat could be ready to rent once it adheres to the rules for your property and council area. We’ll confirm the process and handle the paperwork for you.
3) Downsize your home—without leaving your neighbourhood
If the kids have left home or you’re travelling more, a well-designed granny flat helps you simplify your lifestyle while staying close to friends, services, and familiar routines. It’s not just a smaller footprint; it’s a smarter, easier way to live.
4) Maximise your investment
Make every square metre count. A quality, compliant granny flat can improve livability, increase buyer appeal, and generate a new income stream, making it a smart choice for long-term value. We’ll guide you on sizes, siting, energy efficiency, and finishes that work well in Melbourne’s market.
5) Custom solutions for accessibility
Every resident is unique. We prioritise comfort and independence through features like step-free entrances, wider doorways, accessible bathrooms, smart-home options, safety railings, and well-planned circulation, all tailored to your needs now and in the future.
6) Create a dedicated home office
Working from home is here to stay. A separate, quiet workspace in the garden reduces distractions, enhances professionalism, and keeps the main house for living. Add data cabling, sound insulation, and climate control for a productive, year-round setup.
Our Seamless Process: From Your Vision to Reality
We at Destin Constructions have refined our process over 30+ years to be as stress-free and efficient as possible for you.
It all begins with a chat. We'll visit your property to discuss your needs, assess the site's potential, and explain the feasibility, including council regulations specific to your area. This is where we listen and start shaping your dream.
Our design team will develop concept plans tailored to your block, budget, and needs. Unlike other Granny Flat builders in Melbourne, we offer a detailed, fixed-price quote at this stage, so you know exactly what to expect with no hidden costs.
Council paperwork can be overwhelming. Our team manages all the documentation and submissions, using our extensive knowledge of local council requirements in Melbourne to obtain the necessary permits for you.
This is where your vision becomes reality. Our skilled project managers and builders work hard, upholding top quality standards and providing you with regular progress updates.
We guide you through your completed, stunning granny flat to ensure every detail meets your satisfaction and our strict standards. We then hand over the keys, along with all relevant documentation and warranties.

Frequently Asked Questions - Granny Flat Melbourne
Do I need a council permit to build a granny flat in Melbourne?
Yes, but the process has become much easier! This is the most important update for Melbourne homeowners:
Planning Permit (Often Not Needed): Thanks to recent Victorian Government changes, a “small second home” (granny flat) up to 60 square metres on a property over 300 square metres no longer needs a planning permit (as long as there are no special overlays like heritage or flood zones).
Building Permit (Always Required): You always need a building permit. This is non-negotiable and ensures your granny flat is built safely and meets all Australian building codes for structural integrity, fire safety, and energy efficiency.
We, at Destin Constructions, handle this entire permit process for you, providing a seamless, stress-free experience.
Can I legally rent out my granny flat in Melbourne?
Yes, you can. This is the other game-changing new rule in Victoria. The new “small second home” regulations (which replaced the old “Dependent Person’s Unit” rules) explicitly state there are no restrictions on who can live in the granny flat.
This means you are now free to:
- Rent it out to the public for a secondary income stream.
- House family members or friends.
- Use it as a home office or guest house.
This has turned the granny flat from just a family solution into one of the best investments a Melbourne homeowner can make.
How much does building a granny flat in Melbourne cost?
As a custom builder, every project varies. However, the typical price for a fully finished, turn-key granny flat in Melbourne ranges from $120,000 to over $200,000.
The final price depends on:
- Size: A 1-bedroom versus a 2-bedroom design.
- Site: Access, and whether your block is flat or sloped.
- Finishes: Your choice of kitchen, flooring, and bathroom.
We provide a detailed, fixed-price quote after our free site assessment, so you know all your costs upfront, no hidden surprises.
What’s the difference between a "DPU" and the new "Granny Flats"?
You will see the old term “Dependent Person’s Unit” (DPU) on many council websites. This was the old, restrictive rule.
A DPU (Old Rule): Was a “movable” unit only for a person dependent on the main home’s resident. It could not be legally rented out and had to be removed when the dependent person left.
A “Small Second Home” (New Rule): This is the new, official term for a granny flat. It is a permanent structure, can be used by anyone, and can be legally rented out.
We build modern, permanent “small second homes” that are a world away from the old DPU.
How long does the building and approval process take?
The entire process is now much faster.
Pre-Construction (Approvals): Because a planning permit is often no longer needed, this stage can be very fast—just the time to get your building permit, which is a few weeks.
Construction: Once on-site, a typical build takes approximately 12 to 16 weeks.
As Melbourne’s most reliable builders since 1991, we are known for our efficient project management and on-time completion.
How big can I build my granny flat in Melbourne?
The new, streamlined approval process applies to “small second homes” with a maximum gross floor area of 60 square metres.
This is a surprisingly large and comfortable space! We, at Destin Constructions, are experts at designing 1 and 2-bedroom layouts that feel spacious, open, and modern within this footprint. If you wish to build larger, we can still do that, but it would require a full planning permit.
How much value does a granny flat add to a Melbourne property?
A professionally built granny flat adds value in two ways:
- Capital Value: Industry experts (like CoreLogic) report that a granny flat can increase a property’s value by up to 30%.
- Rental Yield: It provides a brand new, high-yield income stream that can help pay off your mortgage or provide significant extra cash flow.
It is one of the most reliable and highest-returning home improvements you can make.
Is my property suitable for a granny flat?
Most standard Melbourne blocks are now suitable! The main requirements are:
- Your property must be over 300 square metres.
- There must be adequate space (to meet setbacks from the fence line).
- Your property cannot be affected by restrictive overlays (like heritage, flood, or significant vegetation).
- The absolute easiest way to find out is to contact us. We offer a free, no-obligation site assessment to give you a clear answer.
Why choose Destin Constructions over a cheap "kit" home?
A granny flat is a permanent addition to your most valuable asset.
Kit Homes: Often advertise a low “kit” price that doesn’t include site costs, delivery, connections, permits, or installation. The quality can be low, and the final price often balloons.
Destin Constructions (Custom Builder): We provide one, all-inclusive, fixed price. Our structures are built to last with the same high-quality materials and craftsmen as a full-size architectural home. We are top-rated, reliable, and have been serving Melbourne for over 30 years.
Are you a fully licensed and insured builder?
Absolutely. This is non-negotiable. Destin Constructions is a Registered Building Practitioner with the Victorian Building Authority and we carry full builders’ all-risk and public liability insurance. We proudly stand behind our work, our name, and our 30+ year reputation.
