Where your budget matters most
Good value in affordable granny flats in Melbourne comes from spending on the parts that are hard to change later:
- Structure and footings: the right foundation for your soil protects the build for decades.
- Waterproofing: bathrooms and laundries need to be done properly the first time.
- Windows and insulation: these help meet Victoria’s 7-star energy rating and keep running costs down.
- Layout: a well-planned 60m² home with open-plan living feels more spacious than a poorly planned larger one.
Decorative extras, window furnishings and outdoor living can all be added over time. Our guide to what makes a granny flat truly affordable covers this in more depth.
Choosing a floor plan
All five G-Flat™ floor plans cost the same within each finish level, so the right layout never costs more. Stella suits corner blocks, Aurora suits narrow or side-access lots, Lana fits most backyards, Lana 2 adds a second bathroom and Sirius offers larger bedrooms.

How to compare affordable granny flat quotes
When you compare affordable granny flats in Melbourne, the headline price is only the starting point. Ask each builder:
- Is the building permit included, along with all plans and reports?
- How far does the service connection allowance run?
- Which benchtop, flooring and appliance brands are included?
- Are decking, heating and cooling included?
- What warranty applies, and for how long?
- Is the price fixed once your site has been assessed?
If an item is not listed, ask before you sign. Read fixed price granny flats in Victoria to see why a clear price matters.
Site factors that can change the price
The turnkey price covers a standard site. Your free site assessment checks for anything that could add cost, such as:
- services that need to run more than 10m (see services connection costs beyond 10 metres)
- sloping blocks that need extra earthworks
- heritage, bushfire or flood overlays
- easements or covenants on your title
- lots under 300m², which usually need a planning permit
The Victorian Government small second dwellings page explains the official rules, and our granny flat compliance guide for Victoria covers what to check on your block.
Any site costs are confirmed in writing after your site assessment, before you commit to a build.
