A look inside Perth Granny Flats

People decide upon buying and building a granny flat for a multitude of reasons, allowing they have the room for one on their block. They can be as big or as small, as customisable or stock-standard as you’d like.

Here’s what they’re mostly used for:

  • When people want their elderly parents or grandparents to be close and cared for without going into care homes
  • When a family is outgrowing the main home and more space is needed for recreation or downtime
  • When people work from home and want an office that’s separate to the main home
  • When guests come over or perhaps as an Airbnb, or
  • To rent out to tenants.

When looking at granny flats in Perth, you’ll be able to walk through our high-quality showroom display designs and discover the full turnkey, cost-effective solution for your needs.
