Design Philosophy
Family-scale space, transportable thinking.
This model brings more internal room to the portable granny-flat category without abandoning the efficiency of a foldable format.
The terrace-ready arrangement helps the building feel more like a small home and less like a temporary unit.

The three-bedroom layout supports family accommodation, guest stays, rental-style use or project accommodation.

Planning Notes
What to confirm before the site is ready.
Delivery & Installation
Most foldable and expandable units are delivered in a compact folded format for efficient transport, then opened and installed on site. Setup timing depends on access, model selection, site conditions and required trades; typical setup is reviewed during enquiry.
Utilities
Water, electrical, plumbing and other service connections must be completed by licensed trades. HVAC, solar and off-grid systems are planned separately unless specifically quoted.
Warranty & Support
Warranty and support terms should be confirmed before purchase. Current product guidance includes support for structure, weatherproofing, internal fittings and manufacturing defects.
Council & Compliance
Approval requirements vary by council, site and intended use. Documentation can be reviewed during the enquiry process, and any final approvals, inspections or site-specific reports should be confirmed before purchase.
Standard Inclusions
Considered, and included.
Transparent Pricing

Site Suitability Matters
The right modular solution still needs the right site conditions.
A modular solution is only suitable if the site can support delivery, access, installation and the intended use. Before final pricing or delivery, key site details may need to be reviewed.
delivery access width and driveway slope
crane or truck access and installation space
ground conditions and site preparation
services, utilities and connection requirements
local council controls and intended use
bushfire, flood, wind or coastal exposure where relevant
Site suitability guidance is preliminary and does not replace advice from builders, engineers, certifiers, planners, installers or council.
Approvals, Delivery & Installation
Council requirements, permits, engineering, delivery and installation conditions can vary by property, council area, intended use and product type. Information on this website is general in nature and should not be treated as building, legal, planning, engineering or financial advice. Confirm requirements with the relevant council, certifier, builder, installer, engineer or other qualified professional before making a purchase or project decision.
