In Australia and New Zealand, a Granny Flat refers to a secondary dwelling on a residential property. Traditionally designed for aging parents or extended family members, these compact homes are now widely used as rental units, guest houses, or flexible living spaces. A Granny Flat usually includes a living area, bedroom, kitchen, and bathroom, offering independence while remaining close to the main house.
Granny Flats have seen a surge in demand across Australia and New Zealand due to:
Housing Affordability Challenges – Rising property prices push families to seek cost-effective solutions.
Multi-Generational Living – Families want independent yet connected spaces for elderly parents or young adults.
Rental Income Potential – Many homeowners build Granny Flats to generate long-term rental income.
Flexible Lifestyle – Can serve as a home office, Airbnb unit, or guest accommodation.
Government Policy Support – Local councils increasingly approve secondary dwellings to address housing shortages.
