A Custom 700 Expandable Container House is a transportable building whose final dimensions, room arrangement, and equipment should be confirmed with the supplier before purchase. The number “700” is not a universal industry specification: it may refer to a model, a target area, or another supplier-specific designation. If you mean approximately 700 ft² of usable space, that is about 65.0 m², but confirm whether the quoted area is measured open, enclosed, gross, or net. For an accurate quotation, share your site conditions, intended use, required layout, and delivery destination.

This guide is for developers, contractors, project owners, and sourcing teams comparing expandable container houses for accommodation, temporary offices, site facilities, or other project uses. It is especially useful if you have a “700” model reference but have not yet confirmed its dimensions or internal configuration. The same model name can describe different specifications across suppliers, so written drawings and a detailed quotation matter more than the label alone. Use the following steps to turn an initial product inquiry into a comparable, buildable specification.
An expandable container house is designed to be transported in a compact form and opened at the project site to create additional enclosed floor space. A double-wing configuration generally uses side sections that unfold from the main transport body, but the exact mechanism, support arrangement, and finished dimensions depend on the selected design. Buyers should ask for drawings showing both the transport configuration and the fully expanded configuration. Confirm what foundation, anchoring, lifting equipment, and site labor are required before planning installation.
Construction details can vary by supplier and project. Ask for the proposed frame material and section details, wall and roof panel construction, floor build-up, door and window specifications, and the finishes included in the quoted scope. Insulation, glazing, fire performance, corrosion protection, and weather resistance should be specified against your project requirements rather than assumed from product images. Where a performance requirement matters, request the applicable product documentation and clarify whether it applies to the complete building or only to a component.
The right layout depends on occupancy, circulation, privacy, and the building’s intended use. A simple open room may suit a temporary work area, while accommodation can require separate sleeping space, a bathroom, and a defined entrance route. An office may need a reception or meeting zone, storage, and planned electrical points. Request a dimensioned floor plan before production so that room sizes, door swings, windows, and furniture clearances can be reviewed together.
These are planning concepts, not guaranteed standard configurations. Ask the supplier which partitions and fixtures are included, which are optional, and whether a requested arrangement affects the structural design or transport dimensions. If “700” refers to an area target, state whether that figure means total expanded floor area or usable internal area. This prevents a mismatch between the product label and the space your project actually needs.
Do not approve a purchase based on a model name or a headline area alone. Compare the same information across supplier quotations, and request measurements for the expanded building as well as the folded transport unit. A useful drawing package includes a dimensioned floor plan, elevations, door and window positions, and service locations. For drawing review, you can ask the supplier to provide a 1:50 scale layout where suitable; the scale is a documentation request, not a product performance claim.

| Specification area | What to request | Why it matters |
|---|---|---|
| Dimensions | Transport size, expanded external size, internal clear dimensions, and stated floor-area method | Checks transport feasibility and usable space |
| Structure and envelope | Frame details, panel build-up, floor construction, roof design, and finish options | Allows technical review against site and use requirements |
| Openings and layout | Door and window sizes, positions, partitions, and access routes | Reduces layout and installation conflicts |
| Utilities | Electrical scope, plumbing provisions, ventilation, and connection points | Clarifies what must be arranged locally |
| Supply scope | Included accessories, packing, delivery terms, installation support, and exclusions | Makes quotations easier to compare |
Start with the project location, the building’s use, expected occupancy, and the conditions the structure must handle. Share available site access information, ground or foundation plans, local weather considerations, and any applicable building requirements with the supplier. Confirm whether local approvals, utility connections, or professional review are required before ordering. Requirements differ by location, so do not assume that a supplier’s standard configuration automatically meets local rules.
Mark the rooms, openings, equipment, and service points you need on a preliminary plan. Ask the supplier to identify which items are standard, customizable, optional, or outside the supply scope. Review the unfolded layout alongside the transport configuration to ensure that requested features do not create handling or delivery issues. Before production, approve the final drawings and record the agreed materials and dimensions in the purchase documents.
Price can be affected by dimensions, internal partitions, insulation, doors and windows, electrical or plumbing work, finishes, packing, shipping, and installation requirements. Request itemized quotations that state currency, delivery terms, payment schedule, production assumptions, and exclusions. Ask for the estimated lead time in calendar days and identify when that period begins, such as after drawing approval or deposit receipt. Minimum order quantity and delivery availability should be confirmed directly for your configuration and destination rather than inferred from a product listing.
At Hongshun Guangju, we recommend beginning a project inquiry with the intended use, target area, site destination, preferred layout, and any required performance or utility details. Our team can use that information to discuss a suitable configuration, clarify customization points, and prepare information for quotation and review. The final scope should be confirmed in drawings and commercial documents so that both parties work to the same specification. For a focused discussion, send your project requirements and identify whether “700” refers to a model designation or a target floor area.
A frequent mistake is treating “700” as a standardized size without checking the supplier’s definition. Another is comparing headline prices when one quotation includes partitions or utility provisions and another does not. Buyers can also overlook delivery access, lifting arrangements, foundations, or local approval responsibilities, all of which may affect the project plan. Resolve these questions before confirming an order, not after production drawings have been approved.
A Custom 700 Expandable Container House should be selected from verified dimensions, a practical layout, and a clearly documented supply scope—not from its model name alone. First confirm what “700” means, then match the expanded floor plan to the intended use and review materials, utilities, delivery, and local requirements. Request dimensioned drawings, itemized pricing, and a stated lead-time basis so you can compare suppliers consistently. When you are ready to proceed, send Hongshun Guangju your target area, application, layout priorities, site destination, and desired delivery schedule to start a configuration and quotation review.
