• Lana: balanced, and fits most backyards.
• Lana 2: adds a second bathroom.

Permits, approvals and the new 80m² limit

Since 15 October 2026, a small second dwelling in Victoria can be up to 80 square metres (previously 60 square metres). A planning permit is generally not required in residential and rural zones, although lots under 300m² and some overlays may need one. A building permit is always required. Read the Victorian Government small second dwellings page and our guide to the 80m² granny flat rules in Victoria.

Our prices are for the standard 60m² G-Flat™. Larger layouts under the new limit can be discussed. The building permit is included in every G-Flat™ price, and granny flat approvals in Victoria explains the process. A granny flat also needs an existing home on the same lot, which is why you can’t build a granny flat on empty land.

How long it takes

A G-Flat™ takes approximately 5 months end to end, from planning through to handover.

Paying for your G-Flat™

Homeowners usually fund a build through savings, home equity or a construction loan, and a mortgage broker can tell you what suits you. See how to finance a granny flat build and our granny flat grants guide.
