A 700 Double Wing Expandable Container House is a transportable building concept whose side sections open out from a central module to create a wider usable interior. Before ordering, buyers should confirm what “700” means in the supplier’s model naming, then compare the unit’s transport and deployed dimensions, structural and finish options, utility requirements, and delivery scope. The name alone does not establish a verified size, capacity, or specification. This guide explains what to request and how to plan a purchase without treating unconfirmed product details as fixed facts.

This guide is for developers, contractors, distributors, project owners, and procurement teams considering an expandable modular building. It is especially useful when a project needs temporary or relocatable space, such as a site office, accommodation area, sales room, or service facility. Buyers comparing quotations can also use the checklist to make sure suppliers are pricing the same configuration. Final suitability depends on the project location, applicable requirements, and the confirmed design.
The basic arrangement combines a central section with two wings that fold or close for transport and open at the destination. The expanded layout can provide more floor area than the transport configuration, but the actual footprint and room arrangement depend on the specific design. Buyers should request drawings for both folded and deployed states, rather than relying on a product name or promotional image. Confirm how the wings are supported, connected, sealed, and secured once open.
Ask for the overall transport dimensions, deployed external dimensions, usable internal dimensions, unit weight, and any requirements for lifting or unloading. These figures affect route access, transport planning, crane or forklift arrangements, and site layout. Request a dimensioned drawing that identifies doors, windows, partitions, and service openings. Confirm whether the quoted configuration includes the same features shown in that drawing.
Structural information should be reviewed in relation to the intended site and local design requirements. Request details of the frame material and layout, floor construction, roof assembly, connection method, and any stated design loads or limitations. Do not assume a unit is suitable for a particular wind, snow, seismic, or occupancy condition unless the supplier has provided relevant documentation and the project’s qualified professionals have reviewed it. Site-specific foundations and anchoring may also require separate design.
Ask suppliers to identify the proposed wall, roof, floor, door, and window materials, including finish options and any insulation specification. Performance can vary with material thickness, construction details, installation, and climate, so compare written specifications rather than descriptions such as “high quality” or “all weather.” Clarify whether interior finishes, sanitary fittings, lighting, wiring, air conditioning, and plumbing are included, optional, or excluded. The most appropriate package depends on how the building will be used and maintained.
Configuration choices may include open-plan or partitioned interiors, different window and door positions, and options for electrical or plumbing provision. For a site office, workspace and cable routing may be priorities; accommodation may require a different combination of privacy, ventilation, and sanitary facilities. Confirm which changes are feasible at the manufacturing stage and which would require work after delivery. Any customization should appear in the approved drawings and quotation.
Start with the activities the building must support, not simply the largest available layout. A project office may need meeting space, storage, and reliable power access, while a temporary service point may prioritize customer circulation and visibility. Accommodation use calls for closer review of privacy, ventilation, sanitation, and local occupancy requirements. For each use, list essential features separately from optional upgrades so suppliers can quote a clearly defined scope.

For a simple comparison sheet, record three dimensioned values for each offer: transport length in millimeters (mm), deployed width in millimeters (mm), and usable internal height in millimeters (mm). Also request the unit weight in kilograms (kg) and the electrical input requirements in volts (V), where applicable. These are information fields to obtain from the supplier, not assumed specifications for every 700 model. Keep each value tied to a drawing revision or written quotation so that later changes are visible.
There is no reliable universal price or lead time for a 700 Double Wing Expandable Container House based on the model name alone. Cost can depend on dimensions, material and finish choices, interior fit-out, order quantity, packaging, shipping destination, and whether installation or site work is included. Request an itemized quotation that separates the base unit from options and logistics. Ask the supplier to state the minimum order quantity, production schedule, payment milestones, quotation validity, and what events may affect delivery timing.
When comparing suppliers, use a like-for-like scope. A lower initial quotation may exclude utilities, interior equipment, unloading, or installation, while a higher one may include some of those items. Confirm the delivery term and responsibility for transport, import duties, permits, and on-site handling before placing an order. For project budgeting, keep contingency for local preparation and work that falls outside the supplier’s scope.
Ask for evidence that corresponds to the proposed configuration rather than relying on generic brochures. Where compliance documents, test information, or certifications matter to the project, identify the exact requirement and confirm whether the supplier can provide applicable, verifiable documentation. Do not assume that documents for another model or market apply to the unit under consideration. Have local consultants confirm what approvals and inspections are required at the destination.
A frequent purchasing error is treating “700” as a guaranteed dimension or capacity. Model labels can vary by manufacturer, so obtain the actual measurements and scope in writing. Another risk is planning only for the expanded footprint while overlooking transport access, lifting space, or room needed to open the wings. Include both delivery and operating configurations in site coordination.
Buyers can also underestimate the importance of foundations, drainage, utility connections, and local approval processes. These are not automatically resolved by purchasing a modular unit, and responsibilities may be divided between the manufacturer, installer, contractor, and owner. Assign each task before order confirmation and verify who supplies drawings or connection points. If the unit will serve as accommodation or a regularly occupied workplace, check applicable safety and building requirements early.
As a supplier of expandable container house solutions, Hongshun Guangju can discuss configuration requirements and prepare a quotation around a buyer’s intended application. Share the destination, quantity, use case, preferred layout, required services, and any project drawings when making an inquiry. We recommend confirming dimensions, materials, included options, logistics, and project responsibilities in the written offer before production. This creates a clearer basis for technical review and procurement comparison.
A 700 Double Wing Expandable Container House can be a practical modular option when its transport arrangement, expanded layout, and project requirements are properly matched. The model name is not a substitute for verified drawings, material details, structural information, and a clearly scoped quotation. Start by defining the use and site constraints, then compare suppliers against the same written specification. The next step is to send Hongshun Guangju your project brief and request dimensioned drawings and an itemized proposal for review.
