What is a Granny Flat
A granny flat is a space that is designed for one or two people to live comfortably. You can choose whether your granny flat is detached or semi detached based on your needs and how much space you have.
The reason they are called granny flats is that for years they have been the go-to option for people who have ageing parents who they want to look after. Sometimes they might be called an in-law apartment, a granny pod, or a mother-in-law unit.
There are plenty of granny flat design options to suit most tastes, and you can work with granny flat builders to get the solution you need.
What does it cost to build a granny flat?
The cost of your granny flat construction will change based on the requirements. For example, you might decide that a two-storey detached granny flat is the best option for you. Depending on your budget, you might decide that you’d prefer to have either higher or lower-cost materials, which will also change the cost of the granny flat.
You can get a good understanding of how much your granny flat would cost by discussing it with a granny flat construction company.
Custom-built granny flats vs kits vs flat packs
For those on a budget, you might consider getting a kit or a flatpack granny flat; the kits can cost anywhere between $100,000 and $200,000. The price of the kit will vary depending on what the pack has included and the style that you have chosen. The benefit of packs and kits is that they can be shipped to you no matter where you are; the downside is that you will need to put them together once it has arrived.
You’ll need to factor in getting electrics and water connected, which should be done by a professional.
When considering a granny flat kit or flatpack, be sure to get multiple quotes and ask what is included in the price.
There are a couple of added costs to consider, too:
- Site costs,
- Council approval,
- Plumbing, and electrical work,
- Power points,
- Kitchen and bathroom,
- Laundry areas,
- Lighting
Do I need council approval to build a granny flat?
While granny flats don’t need council approval, you will need the following:
- Complying Development Certificate to make sure your development meets the criteria, and you’ll need to use a private certifier.
- Development Approval is a process that you will go through the council to get approval.
