700mm Wide Dual Wing Expandable House Buying Guide: Dimensions, Layout, and Project Requirements

A “700mm wide” description is not enough to confirm the overall size or suitability of a dual wing expandable house. It equals 0.7 m, but it may refer to a particular component or a transport-related measurement rather than the complete folded or expanded unit. Before comparing suppliers, ask for dimensioned drawings that show the folded footprint, expanded footprint, internal clearances, and the exact meaning of the 700 mm figure.

This guide helps project owners, contractors, distributors, and procurement teams evaluate layout, site readiness, materials, and supplier documentation. At Hongshun Guangju, we recommend matching the unit’s confirmed drawings to the project brief before discussing price or delivery. That approach reduces the risk of ordering a house that cannot be transported, installed, or used as intended.

Key Takeaways

  • Confirm what “700 mm” measures; do not treat it as the total house width without supporting drawings.
  • Compare folded and expanded dimensions, room layout, access routes, and site services as separate requirements.
  • Ask suppliers to identify included materials, finishes, doors, windows, utilities, and optional items in writing.
  • Request a project-specific quotation that states configuration, quantity, packaging, delivery assumptions, and lead-time conditions.

Who This Buying Guide Is For

This guide is for buyers sourcing an expandable house for a construction site, temporary accommodation, a remote work location, a sales or service point, or another project-based use. It is also useful for importers and distributors who need comparable specifications from multiple manufacturers. The same model name can be presented differently by different sellers, so a shared specification checklist is important.

If you are planning a permanent residence or a regulated commercial building, treat the expandable unit as one part of a broader construction project. Local rules may apply to occupancy, foundations, fire safety, structural design, electrical work, plumbing, and accessibility. Confirm those requirements with the relevant local professionals and authorities before placing an order.

What Is a Dual Wing Expandable House?

A dual wing expandable house is a transportable building concept in which two side sections, or wings, unfold or extend from a central section to create a wider usable layout. The exact mechanism, dimensions, and included equipment depend on the manufacturer’s design. “Expandable” describes the configuration approach; it does not by itself confirm expansion time, structural capacity, insulation performance, or compliance with local building rules.

Understand the 700 mm Dimension

Ask the supplier to mark the 700 mm measurement on a drawing and state whether it refers to a folded component, a structural element, a clearance, or another dimension. Request the complete outside dimensions in both transport and deployed configurations, preferably as length × width × height in millimeters. Also ask for internal room dimensions and the clear opening widths of doors and passageways, since outside measurements do not show how much usable space each room provides.

Dimensions, Materials, and Layout to Review

Folded and Expanded Footprints

Transport dimensions determine whether the unit can travel along the planned route and fit the selected delivery method. Expanded dimensions determine whether it fits the site while leaving room for access, installation, and maintenance. Compare both sets with the site plan, and check the supplier’s required working space around the unit rather than relying on the footprint alone.

For a simple planning example, a hypothetical clear pad measuring 12 m by 8 m provides 96 m² of area before accounting for access, setbacks, drainage, or other site needs. This is an arithmetic example, not a recommended pad size or a product specification. Your actual site plan should use the confirmed dimensions of the selected configuration and the requirements of the project location.

Structure, Panels, and Finishes

Ask for a component schedule that identifies the frame material, wall and roof panel construction, floor build-up, surface finishes, and any corrosion-protection treatment. A material name alone does not establish suitability: thickness, connection details, finish, exposure conditions, and maintenance needs can also matter. Request product documentation for the specific configuration being quoted, and have a qualified professional assess whether it suits the intended climate and use.

Clarify whether the quoted house includes insulation, internal partitions, windows, doors, lighting, wiring, plumbing, sanitary fittings, or air-conditioning provisions. These items may be standard, optional, or excluded depending on the supplier and specification. Ask the supplier to separate included items from optional upgrades so that quotations can be compared on the same scope.

Layout and Occupancy

Start with the activities that must take place inside the house, then map rooms, circulation, storage, and furniture around those needs. A sleeping layout may prioritize beds and privacy, while a site office may need desks, meeting space, and secure storage. For accommodation or public-facing use, consider how people enter, move through, and exit the space, and confirm applicable local requirements.

Request a floor plan that labels room dimensions and shows doors, windows, partitions, and fixed equipment. Check whether the expanded wings create a continuous usable floor or whether thresholds, joints, or level changes affect circulation. If several units will be installed together, ask how the proposed arrangement affects entrances, service connections, and movement between units.

Match the Configuration to the Project

The right configuration depends on the job, not simply on the “dual wing” label. Temporary worker accommodation may require sleeping capacity, washroom provisions, and practical cleaning access. A construction office may place more value on workstations, document storage, power distribution, and a layout that supports daily coordination.

For a remote or constrained site, make transport and installation part of the initial selection. Share route restrictions, delivery access, unloading arrangements, ground conditions, and available lifting equipment with the supplier. Do not assume that a compact folded form automatically guarantees access to the site; transport dimensions and handling requirements need to be checked against the real route.

Buyer Selection Framework

  1. Define the use: State the intended occupancy, daily activities, project duration, and whether the unit is for temporary or longer-term use.
  2. Confirm dimensions: Obtain dimensioned folded and expanded drawings, clarify the 700 mm reference, and verify internal clearances.
  3. Check the site: Provide site access details, available footprint, ground and drainage information, utility availability, and any known restrictions.
  4. Specify the scope: List room layout, materials, finishes, doors, windows, insulation, electrical or plumbing provisions, and requested options.
  5. Review compliance: Identify the project location and intended use, then confirm required approvals and technical reviews with local authorities or qualified professionals.
  6. Compare quotations: Align configuration, quantity, packaging, delivery terms, exclusions, payment conditions, and lead-time assumptions before comparing prices.

Price, MOQ, and Lead-Time Questions

The purchase price can vary with dimensions, layout, material choices, interior fit-out, order quantity, packaging, and delivery destination. A low headline price may exclude options or project costs that another quotation includes. Ask each supplier to provide an itemized scope and clearly identify any taxes, freight, unloading, installation, or site work that are outside the quoted price.

Minimum order quantity and production lead time are supplier- and configuration-specific, so request current terms for your exact order rather than relying on a general estimate. Confirm when the lead-time period begins, what approvals or drawings are required beforehand, and how changes after confirmation may affect the schedule. For multi-unit projects, also ask whether production, inspection, packing, and shipment can be planned in phases.

Supplier Evaluation Checklist

A reliable sourcing process depends on clear, verifiable information. Ask prospective suppliers for the following materials and confirm that each applies to the model and options in your quotation:

  • Dimensioned folded and expanded drawings, including the stated 700 mm measurement.
  • Floor plan, component and material schedule, and a clear list of included and optional equipment.
  • Installation, unfolding, connection, and maintenance instructions relevant to the quoted configuration.
  • Available product documentation and details of any testing or compliance documents claimed for the specific product.
  • Written quotation showing quantity, packaging, delivery assumptions, payment terms, and schedule conditions.
  • Confirmation of how questions, specification changes, and after-sales requests will be handled.

Do not treat a general brochure or an unmarked image as a substitute for a project-specific drawing. If a supplier cannot explain a dimension or an inclusion, request clarification in writing before approving the order. Keep the confirmed specification, drawings, and quotation aligned so that procurement, logistics, and site teams are working from the same version.

Common Buying Mistakes and How to Avoid Them

One common mistake is interpreting “700 mm wide” as the complete building width without checking the reference point. Another is comparing quotes with different fit-outs, which can make a cheaper offer appear equivalent when it excludes requested items. Prevent both issues by requesting dimensioned drawings and a line-by-line scope comparison.

Buyers may also focus on the expanded room layout and overlook folded transport size, delivery access, or the space needed for installation. Others assume that a supplier’s standard design automatically meets local rules or site conditions. Share project constraints early, confirm responsibilities in the contract, and arrange independent technical review where the use or location requires it.

Next Steps with Hongshun Guangju

To assess a 700mm Wide Dual Wing Expandable House for your project, prepare the intended use, required room layout, site location, access constraints, order quantity, and preferred material or fit-out options. Send these details to Hongshun Guangju and ask us to confirm what the 700 mm dimension represents, provide the applicable folded and expanded dimensions, and identify any project details needed for a quotation. This gives both sides a clear basis for checking suitability before commercial terms are finalized.

Conclusion

A 700mm Wide Dual Wing Expandable House should be selected through verified dimensions, a practical layout, site and transport checks, and a clearly documented supply scope. The key first step is to confirm that 700 mm refers to the measurement you expect; the label alone does not establish the building’s overall width. Once you have the drawings and project requirements, compare suppliers on the same configuration, inclusions, delivery assumptions, and documentation.

For your next step, prepare a brief with the intended use, site information, desired layout, quantity, and required options, then request a project-specific drawing and quotation from Hongshun Guangju. Confirm local approvals and technical requirements with the appropriate professionals before ordering or installing the unit.
