Granny Flat designs and builders in Brisbane

The backyard shed or garage turned living space has certainly come a long way over the years, with many homeowners now opting to construct brand new granny flats that resemble miniature houses on their properties.


What is a Granny Flat?

A granny flat is a term used for secondary dwelling on a property. They can be built attached to the main house or garage, or can be a separate structure. In some cases it can actually be cheaper to create a new building as it does not interfere with the structure of the house – and this is one of the key reasons granny flats are growing in popularity as a more cost effective alternative to renovation. Granny flat are smaller than the primary home on the block, as they can only be 60 square metres in size. Designs are varied, some even consisting of three bedrooms plus kitchen, dining and living spaces, while others are simply one large space that acts as a home office or hobby space.


How fast can Granny Flats be built?

The beauty is that these secondary dwellings can be built quite quickly, most going up in around 8-12 weeks.


Where can Granny Flats be built?

Granny flats can be built on most residential-zoned properties, but it is best to check with your local council in case there are some restrictions that may prevent you from constructing one on your particular block. The best way to do this is to purchase a planning certificate from the local council.



Depending on the size of your block you may not even need council approval for building a granny flat, just approval from a private certifier, which only takes around 10 days. However if you do need to gain approval from council, the process could take anywhere between 6-8 weeks (again depending on the council and its specific requirements). If your block is over 450 square metres in size and the granny flat does not take up more than 60 percent of the property, your property should be eligible for a granny flat.
