Prefab Granny Flat Designs

Four prefab granny flat models designed for Melbourne and Victorian backyards — from compact studios to full two-bedroom dwellings. All NCC 2022 compliant.

Units under 60m² typically don't need a planning permit in most Melbourne residential zones — only a building permit, which we facilitate for you.

Why Choose a Prefab (Factory-Built) Granny Flat?

Traditional onsite builds depend on weather, multiple trades showing up on time, and site-by-site material decisions. Factory production eliminates all of that variability — every panel is cut, fitted, and inspected under controlled conditions before it leaves the factory.

The result is a more consistent finish, faster installation, and a structure that meets 7-star energy efficiency from day one.

Prefer to manage the installation yourself? See our DIY owner builder granny flat option, or read how the 3-month build process works.

What's included in every model

All models are delivered with structural framing, external cladding, internal lining, insulation to 7-star standard, windows and doors, kitchen and bathroom fit-out, and flooring. Site connections (plumbing, electrical, drainage) are completed by licensed trades during installation.
