Can I add a garage or deck/patio to my granny flat?

Absolutely – you can definitely add a patio or deck to create more outdoor living space that suits your style. A garage is a bit trickier and depends on your block’s access and council rules, but it’s often possible. The good news is patios, decks, garages, and carports don’t count toward the 60m² internal living space limit for granny flats, so you’ve got flexibility to make those areas as big or small as you like.
