700mm Wide Dual Wing Expandable House: Specifications, Setup, and Buying Guide
A 700mm wide dual wing expandable house is a transportable building concept designed to open into a wider usable space at the destination. The name identifies a 700 mm dimension and two expandable wing sections, but it does not establish whether 700 mm refers to the folded width, a panel, or another component. Before comparing suppliers, ask for a dimensioned drawing showing the packed and expanded sizes, the opening arrangement, and the scope of supply. This guide explains what to verify, how to plan setup, and how to evaluate a purchase without treating unconfirmed dimensions as product specifications.

Key takeaways
- Confirm exactly what the 700 mm designation measures; request both transport and deployed dimensions in millimetres.
- Check the structural design, materials, insulation, openings, services, and site requirements against your local project conditions.
- Get written confirmation of the price basis, minimum order quantity, production schedule, shipping configuration, and installation responsibilities.
- Share your intended use, destination, and technical requirements with Hongshun Guangju to support a product-fit and quotation discussion.
Who this buying guide is for
This guide is intended for contractors, developers, distributors, project owners, and procurement teams considering an expandable house for temporary or relocatable use. It is useful when you need to compare a compact transport format with the larger space available after deployment. Buyers should assess the unit as a complete building solution, rather than relying on the product name or exterior appearance alone. Applicable building, transport, electrical, fire, and site rules depend on the destination and intended use.
How a dual wing expandable house works
Basic concept and terminology
An expandable house is transported in a compact configuration and opened at the installation site to create additional floor area. A dual wing arrangement generally indicates two folding or deployable sections, but hinge positions, support systems, and opening sequence can differ by design. The 700 mm figure should therefore be treated as a designation to verify, not as proof of the house’s complete transport dimensions. Ask the supplier to mark the referenced dimension clearly on the technical drawing.
What may be included
Depending on the quotation, a unit may include a frame, wall and roof panels, floor, doors, windows, and selected interior finishes. Plumbing, wiring, lighting, heating, cooling, furniture, foundations, and site connections may be optional or excluded. We recommend requesting an itemized scope that separates standard supply from upgrades and buyer-provided work. This helps prevent different suppliers’ quotations from appearing comparable when their inclusions are not the same.
Specifications to verify before ordering
Dimensions, structure, and materials
Request a drawing with the folded length, folded width, folded height, deployed footprint, room layout, and clear opening dimensions. Confirm which measurements include roof overhangs, steps, or external fittings, and whether the proposed transport configuration matches the intended shipping method. Ask for frame material and section details, connection and locking information, floor build-up, and the supplier’s stated design loads. The 700 mm designation and the dual-wing arrangement are the only dimensions or configuration details established by the product name; all other measurements require supplier confirmation.
Envelope, openings, and building services
Compare wall, roof, and floor materials, including panel construction and any stated insulation thickness in millimetres. Request information on doors, windows, seals, ventilation, and weather protection, then check whether these choices suit the site climate and expected occupancy. For electrical and plumbing options, specify the destination market and ask for system details, connection points, and any exclusions. Do not assume a particular insulation rating, voltage, fire performance, or weather rating unless it is documented for the quoted configuration.

Match the configuration to the application
Potential applications include temporary site accommodation, project offices, staff facilities, and other relocatable spaces, subject to local approvals and the supplied specification. For a site office, prioritize a workable layout, access, lighting, power provisions, and connection points. For accommodation, review privacy, ventilation, sanitation, thermal performance, and the number of intended occupants with the supplier. For repeated relocation, give extra attention to folding components, protective packing, handling instructions, and inspection after transport.
Planning site setup
Step-by-step preparation
- Confirm the package: Check unit dimensions, shipping configuration, lifting points, delivered components, and installation documents.
- Prepare the site: Verify access for delivery and handling equipment, establish a suitable level support area, and confirm drainage and local foundation requirements with qualified project personnel.
- Plan the opening area: Use the supplier’s deployed drawing to keep the required clearance around both wings and to identify any overhead or side obstructions.
- Deploy and secure: Follow the model-specific instructions for unfolding, supports, connections, and locking. Do not substitute an assumed procedure for the supplier’s approved guidance.
- Complete and inspect: Connect only the services included in the approved scope, check doors and windows, and document outstanding work before occupancy.
Site and installation decisions
Before placing an order, identify who is responsible for foundations, unloading, assembly, utility connections, and permits. Ask what crew size and equipment the supplier recommends for the quoted model; those requirements cannot be reliably inferred from “dual wing” alone. Confirm whether installation is included, remote guidance is available, or a local contractor must complete the work. Where wind, snow, seismic, or other environmental loads are relevant, request design information applicable to the project location and have it reviewed by the appropriate professional.
Price, MOQ, and lead time
The purchase price can depend on dimensions, interior fit-out, materials, service options, order quantity, packaging, and destination. Request separate pricing for the base unit and optional items, along with the currency, quotation validity, payment terms, and shipping basis. Minimum order quantity and production lead time are supplier- and configuration-specific, so obtain written confirmation rather than relying on a general estimate. Also ask whether the schedule begins after deposit, drawing approval, or final specification confirmation.
Supplier evaluation checklist
- Can the supplier provide a drawing that defines the 700 mm dimension and shows folded and deployed configurations?
- Does the quotation identify materials, included components, options, and exclusions?
- Are loading, lifting, deployment, and maintenance instructions available for the offered model?
- Can the supplier explain how customization affects dimensions, price, MOQ, and schedule?
- Are packing details, shipping assumptions, warranty terms, and after-sales responsibilities documented?
- Can project-specific compliance documents be supplied where applicable, without relying on unsupported certification claims?
Common buying mistakes and practical advice
A frequent mistake is assuming that the product name gives the complete transport width or the final floor area. Another is comparing quotations without checking whether services, insulation, or installation are included. Buyers can reduce these risks by submitting the same drawing requirements and scope checklist to every shortlisted supplier. Keep approved drawings, finish selections, delivery terms, and change approvals together as part of the purchase record.

Conclusion
A 700mm wide dual wing expandable house can be evaluated effectively when its designation, transport dimensions, deployed layout, materials, setup requirements, and commercial terms are clearly documented. The next step is to request a model-specific drawing and itemized quotation, then compare them against your site conditions and local project requirements. Treat unconfirmed features as open questions, and finalize the order only after the technical scope, delivery responsibilities, and schedule are agreed in writing.
