What is a Granny Flat?
A granny flat is a self-contained living space, typically situated on the same property as a primary residence. It can serve various purposes, such as housing elderly family members, providing rental income, or offering extra space for a growing family.
What does it cost to build a granny flat?
The cost of building a granny flat depends on several factors, including size, design, materials, and location. As a general guide, the total cost can range from $100,000 to $200,000 or more. The table above should serve as a good reference point for overall prices, but the exact cost will depend on the specific build.
Custom built granny flats vs kits vs flat packs
There are three primary construction options for granny flats: custom-built, kits, and flat packs. Custom built granny flats offer the most flexibility in design and layout, but may be more expensive. Granny flat kits are pre-designed and partially assembled, making them a more cost-effective solution. Flat packs provide a basic structure that can be assembled on-site, offering the lowest cost but the least customisation.
Other costs to consider
When budgeting for your granny flat, it is important to consider additional costs, such as site preparation, utilities, landscaping, and council fees. Ensure that you have a clear understanding of what is included and excluded in your builder’s quote to avoid any surprises down the track.
Do I need council approval to build a granny flat?
Council approval is generally required to build a granny flat. However, the specific regulations and requirements vary between local councils. It is essential to consult your local council and understand the necessary permits and approvals before starting construction.
Will a granny flat increase the value of my home?
A well-designed and constructed granny flat can increase the value of your property. It provides additional living space and potential rental income, which can be attractive to potential buyers. However, it is essential to consider the local market and ensure the granny flat meets the needs of your target demographic.
Building a granny flat can be a smart investment, offering financial and lifestyle benefits. By understanding the costs involved and creating a realistic budget, you can ensure a successful and rewarding granny flat project.
