1 Bedroom Granny Flats

A 1 bedroom granny flat is typically between 36m² and 60m², depending on the design, site and how you plan to use the space.

A well-designed 1 bedroom granny flat can comfortably include a separate bedroom, bathroom, kitchen, laundry and open-plan living area. Backyard Grannys offers a variety of 1 bedroom granny flat designs that can be customised to suit your block, lifestyle and requirements.

A 1 bedroom granny flat in Newcastle typically costs from $185,000 to $200,000, however the final cost of your granny flat will depend on factors including your chosen design, site conditions, approval requirements, service connections, finishes, design modifications and any additional works required for your property.

For a 1 bedroom granny flat in NSW, your block will generally need to be at least 450m² to qualify for complying development.

A compact 1 bedroom granny flat can be a great option where backyard space is limited. Backyard Grannys' Bardo design, for example, has an internal area of 36m² and is designed to make efficient use of smaller or more challenging spaces.

If your block is under 450m², it does not necessarily mean you cannot build a granny flat. Your project may still be possible through a Development Application (DA) with your local council, depending on your property and local planning controls.

The best way to find out what is possible is with a free site assessment. Our team can first assess your property virtually, then visit your block free of charge to review the site, determine whether a CDC or DA approval pathway is most suitable, and recommend designs that could work for your property.

A 1 bedroom granny flat is best suited to one or two people who want a comfortable, self-contained space in a smaller footprint.

For families, a 1 bedroom granny flat can provide independent accommodation for ageing parents, adult children or visiting family members, allowing loved ones to stay close while still having their own private space.

For investors, a 1 bedroom granny flat can create an additional rental opportunity while using less backyard space than a larger design, making it worth considering for properties where space is limited.

Alternatively, a 1 bedroom granny flat can be used as a guest retreat, home office, studio, pool house or private space that adds flexibility and value to your property.

Backyard Grannys' Bardo design, for example, is 36m² and includes a separate bedroom, bathroom, internal laundry and open-plan kitchen, dining and living area, making it a practical option for smaller blocks and compact backyard spaces. Similarly the Seaforth design is 45 m² and is a generous one‑bedroom granny flat with all the comforts of home.
