FAQs
Your questions, answered.
A few of the most common questions we hear about granny flats, the build process, and how Dwellix works. If yours isn't here, get in touch.
General
Do you provide warranty?
Yes, as registered builders in Australia, Dwellix provides a 10-year structural warranty, covering the major structural elements of your home, as well as a 2-year non-structural warranty period for items such as finishes, fixtures and minor defects. This ensures your home is built to last, with peace of mind knowing you are protected under Australian building standards.
Are disability options available?
Yes, Dwellix can incorporate disability-friendly design features where required. We are able to work with NDIS requirements and guidelines, ensuring your home is designed for accessibility, comfort and long-term functionality. This can include features such as wider doorways, step-free access, accessible bathrooms and other modifications tailored to individual needs. Our team will work closely with you to ensure the design meets both your lifestyle and compliance requirements.
What is a granny flat?
A granny flat is a self-contained secondary dwelling located on the same property as an existing home, typically used for family members, rental income or additional living space.
What's the difference between a secondary dwelling and a granny flat?
They are the same thing. "Granny flat" is the everyday term, while "secondary dwelling" is the planning term councils use. Dwellix designs and builds secondary dwellings: the modern, architectural take on what most people still call a granny flat.
Can I build a granny flat on my property?
This depends on your local council zoning, land size and planning requirements. Most residential properties in Melbourne can accommodate a granny flat, subject to approval.
Do I need council approval?
Yes, in most cases you will need planning and/or building approval from your local council before construction can begin.
Costs & Investment
How much does a granny flat cost?
Granny flats typically range from $200,000 to $350,000, depending on the size, design and specification level selected. At Dwellix, we offer fixed-price designs to ensure full transparency, so you know exactly what to expect with no hidden costs or unexpected variations.
Is a granny flat a good investment?
In our opinion, yes. Granny flats are one of the strongest property investment options in Australia. They offer high rental yields, often generating 3 to 4x higher returns compared to traditional property yield percentages, while requiring a significantly lower upfront investment. This combination of affordability and strong cash flow potential makes them highly attractive for both new and experienced investors.
How much rental income can I expect?
Rental returns will vary depending on the location, design and overall cost of the build. As a general example, a 60sqm granny flat with a build cost of around $250,000 can typically achieve rental returns in the range of $450 to $600 per week. This highlights the strong income potential granny flats can offer, particularly when positioned in high-demand areas and designed to maximise appeal.
Design & Build
What sizes are available?
Granny flats typically range from 1-bedroom to 2-bedroom designs, depending on council regulations and land size.
Can I customise the design?
Yes, you can choose from different floor plans, inclusion packages and façade options to suit your preferences and budget.
What is included in the build?
Dwellix offers comprehensive inclusion packages covering everything from finishes and appliances to key structural elements.
