Modern multi-generational living at its best

Granny flats offer a versatile and affordable living choice for a range of buyers, because let’s face it,
a granny flat is no longer just for grannies.

From retirees wanting to downsize, parents looking for an independent space for their kids, or to those wanting their ageing parents to be close to family for a flexible, multi-generational living arrangement – a granny flat is an ideal solution.

Not only is a granny flat perfect for accommodating a family member, but it’s also presents a great short or long term rental investment opportunity, while maximising the potential of your backyard and is a smart and cost effective way to expand.

The Astaire display is available for you to privately view in Myaree. Contact our granny flat team to book an appointment.

  • We were quite particular about the look we wanted to achieve and the Granny Flat Design Consultant had clever suggestions to get the effect we wanted. We were kept informed at all stages of the build and everyone who worked on the building was considerate and kept the disruption to a minimum.

    Janet & David
  • The Summit Granny Flats team were very accommodating and helpful. Our Design Consultant was very courteous and helpful, nothing we requested was deemed to be unreasonable and he went out of his way to deliver us a brand new home which was on time, on budget and altogether, a very pleasant experience.
