The best granny flat design is not always the biggest one. For investment use, the right choice depends on your starting budget, site conditions, expected weekly rent, occupancy and final project cost.
Cost input
Use the design price as a starting point, then check what your site may add.
Site input
Access, services, foundations, reports and installation needs can change the final project estimate.

Expected rent, occupancy and annual expenses should be checked before relying on a payback estimate.
Indicative only. ROI, rental income, payback and final project cost depend on your land, suburb, site works, services, vacancy, expenses and market conditions. This is not financial advice or a fixed quote.

Land fit first

Usable backyard area affects which layout can be considered.
Narrow access can affect delivery, build method and timing.
Boundaries and nearby buildings affect where the unit may sit.
Water, sewer, stormwater and power need checking early.
A sloping block may need extra review before design decisions.
Some site constraints can limit what can move forward.

Clear answers before you choose a design or send your land details.
Start with the design you like, then check the block. Land size, access, services, setbacks and site constraints can all affect whether a design is the right starting point.
Some changes can be discussed, especially finishes, fixtures and layout preferences. The real limit is usually the site: access, services, slope and approval pathway can affect what is practical.
Approval requirements depend on the property and project pathway, so we do not assume the answer before reviewing the site. You can also read our Granny Flat Rules Victoria guide for general rule information.
Yes, rental use can be part of the plan. Layout, suburb, privacy, finish level and market conditions all matter. For more detail, see our Rental Income Guide.
Choose the layout that matches your main goal. One bedroom is usually a compact starting point, two bedrooms gives more everyday flexibility, and three bedrooms needs more usable backyard space.
No. A larger design usually needs more usable space and a closer check of access, setbacks, services and site conditions. It is better to check the land before assuming a 3 bedroom design will work.
The design is a starting point. Site works, service connections, reports, access, finishes and optional upgrades can all affect the final scope. That is why the land check comes before detailed pricing.
Not from the designs page alone. A final quote needs the land, site conditions, selected design, finishes and scope to be reviewed first. This page helps you choose the right starting point.
