A Solution to the Housing Crisis

Granny Flats in Sydney

Sydney is grappling with a severe housing shortage. The projected deficit between household formation and housing supply in Sydney over the next five years is 12,100 dwellings. This scarcity is clear in rapidly escalating rents, making housing unaffordable for many Sydneysiders.

Granny flats are a practical and affordable solution to this issue. They offer a way to quickly increase housing options, without the need for extensive and time-consuming new construction.
