Looking for a granny flat on wheels or a compact home that can be transported to a new site? YJD’s 20ft two-bedroom foldable tiny house opens into a wider double-wing layout and is shown with exterior stairs. The room plan and interior fit-out can be specified for guest accommodation, a studio, or other compact living needs.
“Transportable” and “road-towable” are not the same configuration. Confirm whether your order includes a trailer chassis, wheels, coupling, brakes, and any destination-specific road approvals before treating the unit as a towable mobile granny flat.
These measurements are from YJD’s 20ft standard double-wing parameter sheet. The expanded footprint is useful for site planning; the folded dimensions support delivery and transport planning.
| Specification | 20ft reference details | Planning use |
|---|---|---|
| Expanded external dimensions | 5,900 × 6,270 × 2,480 mm Side/eave height: 2,180 mm |
Check the opened footprint and clearance around the house. |
| Internal dimensions | 5,640 × 6,110 × 2,240 mm Side/eave height: 2,060 mm |
Plan the bedroom, living, kitchen, and bathroom arrangement. |
| Folded transport dimensions | 5,900 × 2,200 × 2,480 mm | Review route access, unloading space, and lifting arrangements. |
| Reference weight | 2,500 kg | Coordinate suitable lifting equipment and site preparation. |
| Main frame beams | Galvanized Q235B steel, 80 × 100 × 2.5 mm | Other frame members use different sections according to their position. |
The dimensions describe the 20ft standard double-wing house. A trailer chassis or other transport base may affect the overall height and configuration; use the approved drawing for final measurements.
This two-bedroom granny flat layout is intended to balance separate sleeping space with a shared living area. The final position of partitions, doors, windows, kitchen, and bathroom should be reviewed on the selected floor plan.
The expandable house folds inward for transport and opens at the destination. Delivery, unloading, support base, unfolding, fixing, and utility connection are separate planning steps. For a transportable granny flat, confirm who supplies the transport equipment and who is responsible for unloading and installation.
The 20ft reference model uses a galvanized steel frame and insulated sandwich panels. Interior and material selections can be specified according to intended use and destination requirements.
| Component | 20ft reference specification | Options and scope |
|---|---|---|
| Steel frame | Galvanized Q235B steel members | Main beams are listed as 80 × 100 × 2.5 mm; secondary members use separate sections. |
| Side walls | 75 mm sandwich panels with double-sided 0.3 mm color-coated steel facings | EPS, PU, and rock-wool cores are listed choices. |
| Partitions and roof | 50 mm sandwich panels with double-sided 0.3 mm steel facings | Confirm the selected panel core in the order specification. |
| Floor base | 18 mm cement board in the center and 18 mm bamboo plywood on the wings | Finish flooring can be specified separately. |
| Bathroom and kitchen | Configurable interior fit-out | List the included toilet, basin, shower, cabinets, and other fixtures in the quotation. |
| Electrical setup | Wiring and circuit arrangement listed; six LED ceiling lights | Destination-specific outlet and electrical requirements should be agreed before production. |

The listing images include a trailer configuration reference, but the product gallery alone does not establish that a road-ready trailer chassis is included. Confirm the chassis, wheel assemblies, coupling, brakes, and related scope in the quotation.
The 20ft standard double-wing reference dimensions are 5,900 × 6,270 × 2,480 mm expanded and 5,900 × 2,200 × 2,480 mm folded.
The product listing is a two-bedroom foldable tiny house. Confirm the final partition plan, room dimensions, and included interior items in the approved drawing and quotation.
It may suit an additional accommodation or studio project, subject to site access, utility planning, and local planning and building requirements.
No. A folded transport configuration is not by itself proof that a house can be towed on public roads. Verify the trailer equipment, load rating, registration, and local compliance for the specific configuration.
This page describes the 20ft expandable house. The approved drawing, quotation, and sales contract define the supplied configuration, trailer scope, and included fit-out.
