A small granny flat does not need more features. It needs a layout that uses space properly. That is where minimalist design works best. It removes wasted movement, awkward corners and unnecessary walls, so more of the floor area is usable day to day. In Western Australia, granny flats (ancillary dwellings under the R-Codes) can be built more broadly on residential land. Designs up to 70 square metres often do not require planning approval if they meet the relevant criteria.
