One-bedroom granny flats are an economical and versatile option. They are appealing since they are cheap to build and avoid feeling cramped. They are excellent rentals that boost property value. There are existing designs available as well as custom designs offered by Granny Flats WA.
How much does it cost to build a one-bedroom granny flat?
A one-bedroom granny flat is a relatively cost-effective option. Its cost will typically sit between that of a studio granny flat and a two-bedroom granny flat. Its cost will be influenced by its size, design and the materials used.

One-bedroom granny flat requirements
One-bedroom granny flats typically do not require a high amount of space. A granny flat’s allowable size is determined by the lot size of the house. Larger house lots can have larger granny flats built on them. One-bedroom granny flats are typically not very large, meaning they can be suitably built on lots that are not very large. One-bedroom granny flats have similar requirements to other granny flats including planning, building and council approvals.
What are the benefits of a one-bedroom granny flat?
One-bedroom granny flats remain cheap but have more space and privacy than studio granny flats. The bedroom occupies a separate space, freeing the living room from being a sleeping space. Alternatively, the living area can be used as a bedroom like a studio granny flat in order to repurpose the bedroom. One-bedroom granny flats are great as low-cost rentals that add a good amount of property value.
One-bedroom granny flat designs
One-bedroom granny flats have a bedroom with an open space area for the kitchen and living room and separate areas for the bathroom and laundry. They will be working with a larger amount of space than a studio granny flat which can be allocated to living area, outdoor area or kitchen. We at Granny Flats WA have both ready-made designs and custom design options for you.
