What is a Granny Flat?

A Granny Flat can be described as a self-contained dwelling built on the same property as the main dwelling. It contains all the quality & features you would expect if you were building your own home but on a smaller scale. Granny Flats in Sydney have increased dramatically in popularity since the NSW Government changed the approval laws.
Whether you need a Granny Flat for your grandparents, parents, children, newly-weds, extended family, teenagers or simply as an office or an investment we have the right affordable Granny Flat Solutions for your needs.

Design and Approval Process – Can I Build a Granny Flat?

At Granny Flat Solutions, we understand that everyone’s needs, budget and property are different so we customise all of the Granny Flats to suit our Client’s requirements and property type.

In 2009, the NSW Government released the Affordable Housing State Environment Planning Policy (SEPP) which permits all residential home-owners with a property larger then 450m² (which also has a minimum 12m street frontage) to build a Granny Flat on their property if their property is considered to be complying.

With this change comes a new way of processing Granny Flat applications. Home-owners wanting to build a Granny Flat in their backyard are no longer required to obtain Council approval as long as their application meets the minimum Complying Development requirements.
To save you time and stress, our Granny Flat Solutions Design Team can prepare and submit all the applications and detailed architectural plans to obtain approval of your new Granny Flat.

If your property does not meet all the conditions required to be a Complying Development, your Granny Flat can still be approved by lodging a Development Application (DA), to your local Council.
