Hopefully, this article has helped you choose a builder in Melbourne. Though, if you want more information, you can read about what makes a great granny flat builder.


It is important to note that a granny flat in the state of Victoria is known as a “Dependant Person’s Unit (DPU)“. This is as it must be occupied by a person that is dependant upon person/s in the primary dwelling (generally a parent, grandparent, or teenager).


As such, your Council has the authority to impose what type of building the granny flat must be, so it can be removed the moment the dependant ceases to live there.


Depending on you location, your local Council will state the granny flat be either a:


  • A movable building, or
  • A building that can be removed effortlessly.
