What is a Granny Flat?

A granny flat is a secondary dwelling on the same block of land as your primary residence. They can come in many forms, from studio apartments to multi-bedroom homes, and are often used as rental properties or for accommodating extended family members. Granny flat builders must comply with state and local planning regulations, and in some states, they are also subject to stamp duty.

How Much Does a Granny Flat Cost in Australia?

The cost of building a granny flat will vary depending on the size and features of the home, as well as the location. However, as a general guide, you can expect to pay between $80,000 and $120,000 for a small granny flat (one or two bedrooms) and between $150,000 and $250,000 for a larger home (three or more bedrooms).

How Can I Save Money on My Granny Flat Build?

There are several ways to save money when building a granny flat, including:

  • Custom-built granny flats vs kits vs flat packs:

While granny flat kits and flat packs can be a cost-effective way to build, they often lack the flexibility and quality of a custom-built home. If you're looking for a granny flat that is truly unique and tailored to your needs, then working with an experienced builder is the best option. In addition, custom builders will often include granny flat design and approvals as part of their service, which can save you time and money.

  • Council fees and charges: Every Granny Flat must comply with local council planning regulations, which may include fees for lodgement and approval of plans.

  • Stamp duty: Granny flats are subject to stamp duty in some states. This is a one-off tax that is payable on the purchase or transfer of property.

  • Insurance: It is important to insure your granny flat against damage or loss. This will protect you financially if something goes wrong during construction or if the property is damaged after it has been built.

Do I need council approval to build a granny flat?

Yes, all granny flats must comply with local council planning regulations. This includes lodgement and approval of plans, as well as any fees that may be applicable. Therefore, checking with your local council before you begin the construction process is important to avoid any delays or additional costs.

Will a granny flat increase the value of my home?

Granny flats can add significant value to your property, especially if they are well-designed and built with high-quality materials. In addition, granny flats can be a great source of rental income, which can further increase the value of your property.
