Garage conversions & granny flats

Garage sitting unused? Put that space to work.

If the car never goes in the garage, that space could be doing a lot more. What it becomes depends on what your household needs.

Many homeowners have turned theirs into a living area, a bedroom, or a bedroom and bathroom. Or you could add a granny flat on the block.

A granny flat, explained.

  • What it is

    In NSW, a granny flat is known as a secondary dwelling: a self-contained living space, usually for one or two people.

  • Who it’s for

    It can house ageing parents, grandparents or an adult child.

  • Extra income

    Or you could rent it out, subject to council rules.
