Granny flats are a versatile separate living space that can be used for a relative, growing teenager or guest. When not in use, a granny flat can also be used for storage, as a home office, a home gym or art studio. No matter what the intended use, it’s important to engage a qualified, experienced, granny flat builder like Bushewood Building Company, for your next granny flat extension.

Granny flat types

A granny flat can be built in a few different ways, including just renovating your basement, creating a fully independent structure from your house, or doing something like converting a garage that you aren’t using.

Other granny flat benefits

Besides extra space for a family member to live in, a granny flat can also result in a significant increase to the value of your whole property.

When not in use a granny flat can also provide the following additional benefits:


When a granny flat is unused, you can rent it out or use it as an airbnb. Most granny flats have some kind of separation built into them. Some can even have their own kitchens and bathrooms. Granny flats can provide perfect accommodation to university students for example.

Another benefit to granny flats is that you have extra space that you can use to store things when you need to. Plus, you always have extra space for impromptu guests who need a place to stay.

What do you need to build a granny flat?

Any large scale building project is often going to require a bit of preparation before you get started. For example,  you may need to get local council approval and a building permit. Many customers come to Buschewood with their own plans from their architect or draftsman. From these plans, we can build your completely customised granny flat.

It’s also possible for customers to purchase a prefabricated granny flat with separate modules, that we can simply assemble for them. A prefabricated design is often a cost effective way to get a good 2-3 bedroom granny flat, studio granny flat, a shed with granny flat, or whatever other design that you desire.

Getting approvals from local council

After finalising the granny flat floor plans, the next step is to get approvals from your local council. Other approvals may be needed, depending on your location, to ensure the building is done safely. Our building company can help guide you through this entire process. We can also help with creating final plans based on your initial ideas.

Other considerations

Apart from establishing a clear budget, gaining the necessary approvals, and finding a contractor, it’s also important to think about other factors such as utility costs before you start construction. If you’re building a granny flat with its own separate utility costs, it’s important to factor that into your overall budget including costs like air conditioning and heating, water and electricity.

Additionally, you may need to consider any additional maintenance and insurance costs as well. At the end of the day, if you know what all the costs are going to be, you’ll be able to make a manageable budget for getting the whole project built without any nasty surprises.
