Designed for buyers who need flexibility, not just a bigger box
Expandable construction can provide a useful balance between transport efficiency and on-site living space. For the buyer, the real benefit is flexibility: there is more room to separate sleeping, living and service areas while keeping the project centred on a relatively compact modular format. Instead of presenting a long list of factory specification.

Frequently asked questions
Q: What can a 20ft Expandable Granny Flat be used for?
A: Common uses include guest accommodation, a home office, a retreat or flexible family space. The permitted use depends on local planning, building and occupancy requirements.
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: How large is it when expanded?
A: approximately 5900 × 2260 mm when folded and 5900 × 6420 mm when expanded. Treat these as reference dimensions until the final model drawings are confirmed.
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 will 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: 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. Provide a project-specific programme rather than a universal installation promise.
