More space for everyday living and family use
A larger expandable format changes the way the space can be used. Buyers can consider more defined rooms, better circulation and a layout that feels closer to a small home than a single multipurpose studio. This makes the 40ft Expandable Granny Flat relevant for family accommodation, multi-room configurations or buyers who simply value more internal space.

Frequently asked questions
Q: How is the 40ft model different from the 20ft model?
A: Its longer base gives substantially more room for separate bedrooms, storage and a larger shared living area. It also needs more delivery access and a larger prepared site footprint.
Q: Can it be configured with three bedrooms?
A: A three-bedroom arrangement is a practical concept for the larger format, but final room sizes, egress, ventilation, services and circulation must be confirmed in the approved layout.
Q: How does the expandable design work?
A: The dwelling travels in a narrow central form. On site, two side wings unfold to create the wider floor area, after which roof, wall, weatherproofing and service completion steps are carried out under the agreed installation scope.
Q: Does the displayed unit include a kitchen and bathroom?
A: The gallery shows an indicative kitchen and bathroom configuration. Final inclusions, fixtures, finishes and service requirements must be listed in the written quotation.
Q: Is council approval required?
A: Requirements vary by state, council, property and intended use. The owner should obtain site-specific advice and required approvals before installation.
Q: Are foundations and service connections included?
A: Do not assume they are included. Foundations, cranage, plumbing, electrical, drainage and other site works must be clearly allocated in the final scope.
Q: Can the layout and finishes be changed?
A: Selected door, window, exterior, interior and facility options may be available. Feasibility, cost and lead time depend on the confirmed configuration.
Q: How long does installation take?
A: Timing depends on manufacturing, transport, site access, foundations, approvals and service connections.
