Smart Granny Flat Kitchen Layouts: 2026 Guide
Granny Flat Kitchen Layouts
Real dimensions. Real Australian kitchens. What actually fits in 6–10 sqm.
Choosing the right granny flat kitchen layouts comes down to one thing: how much floor space you actually have. Most granny flats sit between 40 and 70 sqm, which leaves room for a kitchen of 6 to 10 sqm — enough to cook properly, but not a centimetre to waste. Get the layout wrong and the whole flat feels cramped. Get it right and even a 6 sqm galley can feel functional and well-designed.
This guide covers the four most common granny flat kitchen layouts — galley, L-shaped, U-shaped, and open-plan bench — with real Australian dimensions, cost bands, and what fits where. Whether you’re still in the planning stage or comparing builder quotes, this is the detail you need before you commit to a layout.

Will Council Approve Your Kitchen Layout?
In most Australian states, adding a fixed kitchen with plumbing to a secondary dwelling triggers secondary dwelling classification — even a kitchenette with a sink can count, depending on your local council. This means you need formal approval before any work starts.
- A kitchen must be a fixed fitout connected to plumbing — portable benchtops or camp-style setups are not compliant.
- In NSW, the kitchen must form part of a self-contained dwelling approved under the Affordable Rental Housing SEPP — no DA or CDC approval, no compliant kitchen.
- All plumbing work must be carried out by a licensed plumber — this is not a DIY item in any state.
- In some councils, the kitchen layout type affects approval — a U-shaped kitchen in a small flat may raise questions about the dwelling’s intended use.
