Granny Flat Design in Perth

Well-designed ancillary dwellings that maximise space, rental potential and site value.

Smarter Use of Your Land

Granny flats, also known as ancillary dwellings, are one of the most effective ways to increase the value and functionality of a property.

They can provide:

❋ rental income
❋ accommodation for family members
❋ home office or studio space
❋ future resale value

However, granny flats must comply with Western Australian planning regulations and local council requirements.

TBARCH helps homeowners navigate these requirements and design compact homes that feel spacious and comfortable.
