Advantages of constructing a granny flat in Sydney
Property Investment
An in-law unit can help increase your property value and potentially allow you to earn rental income.
Multi-Generational Living
A granny flat helps keep the family close while also giving each generation its own space and privacy to be themselves.
Affordable Housing
With the high cost of housing in Sydney, a granny flat is often a more affordable option than buying a new home.


Home Office Space

Guest Accommodation

Rental Income
Rental income from a granny flat: Granny flats can be a way to generate revenue by earning rent and creating a steady stream of regular income.
