1 Bedroom Granny Flat Designs & Floor Plans

Compare granny flat floor plans for your property in Sydney or NSW. Open each design to explore its layout, bedroom arrangement and floor area, then talk to us about access, privacy and any changes you have in mind.

Explore the build price calculator for design options and inclusions, or the approval pricing calculator for approval services. Your site conditions and selected finishes will help determine the final quote.

Comparing plans and prices? Our Sydney granny flat cost guide explains design price examples, approval options and the site costs to check. For completed two-bedroom examples, see how the Grant layout was used in Campbelltown and the Susanna layout in Liverpool.

Check what the floor area includes: the Melanie (64 m²), Kenneth (65 m²) and Joseph (91 m²) figures include patios. Check each plan’s internal area and outdoor space with our team when comparing layouts.

Choose a floor plan that works on your block

Compare the building’s width and depth with the space beside or behind your home. Then look at the entry position, bedroom privacy, room for furniture and storage, and how the windows and outdoor area will relate to the main house. A plan you like is a starting point; the layout still needs to suit your property.

For two-bedroom layouts, read our original two-bedroom granny flat planning guide alongside the current designs below. Our founder Serge Panayi has shared practical granny flat advice since his early Somersoft discussions. Send us your property address and preferred design so we can discuss the layout and the next steps towards a site-specific quote.
