Frequently Asked Questions about Granny Flat Builders in Sydney

What are the advantages of this building type?

These flats are smaller, more compact, more functional, and can be constructed in a fraction of the time as opposed to other building types. With it, you are building on a pre-existing plot of land. You do not need to obtain council permission once you meet the minimum requirements. All in all, this is a great investment. Another advantage is that they are versatile and close to home. If you choose to rent, you will be living next door in case something happens and can exert increased control.

You are simply converting the existing space into a more functional unit.
