Do it by the book

First things first, a crucial initial step of your construction project is getting the approval of your local Department of Planning and Environment. Keep in mind, you should approach this with utmost seriousness because it will help you avoid paying large penalties to the state for breaking zoning laws. It is also wise to seek help from someone who specializes in this matter like a private building certifier. They will examine the land you want to build on and advise you on how to efficiently utilize the available surface you have in order not to get fined by the government.


When it comes to granny flats built for renting purposes, there is only one thing that matters the most – privacy. Imagine inviting a couple of friends over for a quiet get-together while the tenants are having a loud party just a couple of feet away. Or even worse, think about the horror of sharing a driveway and not being able to get to work because their car is blocking it. To avoid this, you should hire experienced professionals like the trustworthy granny flat builders in Sydney who will help you create an intimate granny flat with a separate driveway and walled-off garden where your tenants can enjoy their privacy to the fullest. Lastly, they will make sure that the unit is built according to all the regulations and newest trends.

Get it insured

Getting insurance for your granny flat can be just as important as it is for your main house. For example, if you choose to rent this space, by obtaining insurance you’ll avoid getting sued by your tenants in case an unforeseen accident occurs. Additionally, hiring an agent will be your best move since they will help you avoid unpleasant insurance costs and find the most reasonable quotes. This may be a bit larger initial investment, but we guarantee you that it will pay off in the long run.

Freestanding or not

Before you start designing it, you have to consider whether you want the granny flat to be a separate part of your house or an annex. Choosing to build it detached from your home will mean that the person who inhabits this space can have it all to themselves. On top of that, this kind of arrangement will help you earn some extra money since you’ll be able to rent this space out on Airbnb and similar popular websites. However, building the granny flat as an addition to your home will offer you more functionality in the sense that you can appropriate this room to be a home office, extra storage space, an additional bedroom for kids, etc.

Go green

Last but not least, more and more homeowners are switching to green solutions while designing their granny flats in order to make them as cost-efficient and environmentally friendly as possible. If you choose to follow in their footsteps, the first thing that you need to do is switch to renewable energy sources like solar panels for the front yard and the roof. On top of that, don’t forget to opt for sustainable building materials like non-endangered wood species and low-VOC construction products. Finally, Energy-Star-rated appliances for the flat can earn you hundreds of dollars in savings a year and help protect the environment by reducing your carbon footprint so don’t hesitate to invest in them as well.

As you can see, it doesn’t take much effort to create a wonderful granny flat that will meet the highest standards and serve you as a great guest room or rental unit. All you need to do is follow the laws and regulations and not be afraid to call for professional help. Good luck on your construction project.
