01 / The model
A larger modular plan for family-scale use.
This 12M portable granny flat is designed for customers who need more bedrooms and greater everyday usability than a compact 6M model.
With three bedrooms, kitchen cabinetry and a full bathroom, it can support families, guest accommodation, backyard living, offices, studios or commercial accommodation projects, subject to site-specific requirements.
More rooms, without a conventional build timeline.+
The 12M format gives the plan more breathing room while retaining the transport advantages of a foldable modular structure.
It is a practical option for buyers who need genuine separation between rooms and a more complete compact living layout.
Three bedrooms create flexibility for families, guests, rental-style use or project accommodation.
