Three bedroom granny flats offer more flexibility and versatility than their smaller counterparts because the additional space allows them to be more multi-purpose. The additional floor space also adds more value to both the granny flat, and the original lot and property you’re building on.

What is a granny flat?

A granny flat is a small, self-contained unit, built on the same plot of land as a main house. It’s usually separate from the main dwelling, although it can be built as an extension. Although they were traditionally built to house elderly relatives, hence the name, they can also be rented out for additional income, or used for a variety of other purposes.

What are the benefits of selecting a three bedroom granny flat?

The benefits of selecting a three bedroom granny flat are numerous. Having more bedrooms increases your rental appeal, should you decide you’d like to rent it out in either the long or short-term. It also increases your rental yield, as you are able to appeal to a family market. A three bedroom floor plan also has more flexibility should you want to make your granny flat into a multi-functional recreational space for your own household.

What can it be used for?

Ultimately what you choose to use your three bedroom granny flat for depends on your needs, lifestyle and preferences. Some popular options, aside from housing elderly family members or renting your three bedroom granny flat out, are creating a home office, setting up a creative studio or teenage retreat, or reserving the space for visitors, overnight guests or a nanny or au-pair.

How many people can live in a three-bedroom granny flat?

Restrictions around three bedroom granny flats relate to their size and proximity to other dwellings, rather than how many people can live in them. At a minimum, your granny flat must be three metres away from any fence. If your granny flat is above a certain height, that distance may increase. There may be other approvals based around flat size – usually around 70 m2, though certain councils allow larger – and potential inclusions (parking spaces or accessibility requirements) depending on local council regulations and zoning requirements.

How long will it take to build?

Again, the time it takes to build a three bedroom granny flat will depend on a number of individual factors related to the specific project. The complexity of the build, including size, is one factor to bear in mind, as is the time of year that you are building and the availability of materials and labour. Fundamentally, it might be a small house that you are building, but it is still a house, so could take anything from a few months to a year.

How much will it cost?

Cost of a three bedroom flat will depend on the flat itself and the type of finishes you have selected. Similarly to the duration of the build, labour and materials will have a huge impact on cost. Any required permits and the location also play a part, making it hard to narrow in on a specific cost, though if planned carefully a granny flat in WA could cost as little as $100,000. Depending on the project, however, the budget is likely to be between $100,000 and $300,000, but this is highly variable.
