This 20ft expandable container house features wood-grain exterior cladding and a double-wing layout that opens at the destination to create a wider interior floor plan.

Buyers researching prefab off grid homes can discuss whether this expandable house can be configured for their site’s energy and utility requirements. Solar panels, battery storage, water tanks and wastewater treatment are not identified as standard inclusions in the available product information and must be confirmed separately.
YJD is a prefab house manufacturer in China producing expandable container buildings for international projects. The factory images below show the production environment and examples of modular units. They are factory references and may show models or finishes different from this 20ft wood-grain expandable container house.
Buyers comparing modular home manufacturers in China can request model-specific drawings, material specifications, packing details and an itemized quotation. Factory direct modular homes still require clear agreement on shipping, unloading, site work and installation scope.

The process image illustrates the general folding and expansion concept. Confirm site access, lifting equipment, foundation preparation and installation responsibilities for your project.
The floor-plan image can help start a discussion about the 20ft layout and room arrangement. Living, kitchen, bedroom and bathroom configurations depend on the selected plan. Buyers looking for off grid prefab homes should also plan where energy equipment, batteries, water storage and utility components would be located, then confirm feasibility with the project team.
Wood-grain exterior cladding gives this expandable container house a different appearance from a plain-panel finish. The customization image shows possible exterior additions such as a deck, canopy or roof terrace. These features may be optional and should not be assumed to be standard with this 20ft model.
A prefab off grid house requires more than a prefabricated building shell. The energy and utility package must be planned around occupancy, climate, appliance loads, water use and local requirements. This product information does not identify solar panels, batteries, inverters, water tanks or wastewater systems as standard equipment.
If you are sourcing prefab off grid homes, share your required power capacity, expected daily energy use, water source and wastewater plan. YJD can review whether the requested systems can be included in a project-specific configuration. Do not consider the home off-grid-ready until the complete system and supply scope are confirmed in writing.
When comparing an off grid prefab home manufacturer, expandable container house factory or other modular house suppliers, compare the same drawings and supply scope rather than price alone.

Project requirements can be discussed with the manufacturer. Provide destination, energy demand, water source and wastewater requirements so the requested configuration can be reviewed.
Request model-specific drawings, material specifications, included equipment, packing dimensions, shipping terms, exclusions and a written production and payment schedule.
