Smart Design Features to Look For
1. Open-Plan Living
A well-designed kitchen, dining, and living area forms the heart of every great 2-bedroom granny flat. Open layouts create a spacious, connected feel and allow for flexible furniture placement while enhancing natural light.

For improved privacy, consider layouts with bedrooms on opposite sides of the floor plan — perfect for shared living arrangements or dual rentals.

Stacker or sliding doors that open to a deck or alfresco area help extend living space outdoors, creating a bright, airy, and modern atmosphere.
4. Clever Storage Solutions
Built-in wardrobes, hidden laundry zones, and integrated cabinetry make a huge difference in maintaining a clean, functional home without clutter.
