A “700mm wide” dual wing expandable house needs careful dimension checking before you compare prices or approve a layout. The 700 mm measurement may describe a folded transport dimension, a particular section, or a model designation; it should not be assumed to mean the full-width living space. Ask the supplier to identify exactly what the measurement refers to and provide drawings showing both the folded and expanded configurations. At Hongshun Guangju, we recommend confirming those dimensions, the site conditions, and the intended use together before finalizing a specification.

This guide is for contractors, project owners, property developers, distributors, and procurement teams considering an expandable house for a temporary or permanent-use project. It is especially relevant if “700mm wide” appears in a quotation, product title, or initial specification without a dimensioned drawing. The goal is to help you establish what to measure, how to assess layout options, and which purchasing details to confirm before placing an order. Local building, transport, and installation requirements can vary, so buyers should check applicable rules for their project location.
A dual wing expandable house generally uses a central section with two side sections that fold for transport and open to create additional floor area. The exact arrangement, opening method, structure, and finished dimensions depend on the supplier’s design. This makes the difference between folded and expanded dimensions central to evaluating the unit: one describes the transport configuration, while the other describes the space available after installation. Do not treat a product label as a substitute for a drawing that identifies each measurement.
Start by asking for the dimension’s reference points. Confirm whether 700 mm is the folded width, the width of one wing, a component measurement, or another product-specific figure. Also ask whether the stated measurement is external or internal and whether it includes wall finishes, roof overhangs, or other projecting parts. A written answer tied to a drawing helps prevent misunderstandings between purchasing, transport, and installation teams.
For context, 700 mm equals 0.7 m. If a quotation presents this as the complete interior width of an occupied house, ask the supplier to explain how the intended rooms, furniture, circulation, and access are accommodated. If it refers to a folded section or transport-related measurement, request the expanded external and internal dimensions separately. This clarification is more useful than relying on a generic dimension for all expandable units.
There is no single set of dimensions that can safely be assigned to every 700mm wide dual wing expandable house. Configuration and specifications vary, so use the table below as a request checklist rather than as a claim about a particular model. Ask the supplier to state units and measurement points consistently across the quotation, drawings, and order documents. Where a value is not yet fixed, have it listed as pending approval rather than inferred.
| Dimension or specification | What to confirm | Why it matters |
|---|---|---|
| Folded dimensions | External length, width, and height, with the 700 mm reference clearly marked | Supports transport planning and checks against access constraints |
| Expanded dimensions | Total external footprint and usable internal dimensions | Shows the space available for the planned use |
| Wing configuration | Number of wings, opening direction, and deployed position | Helps assess site fit, access, and installation sequence |
| Structure and finishes | Specified materials, floor build-up, wall and roof finishes, and included items | Enables a like-for-like comparison between suppliers |
| Openings and services | Door and window positions, electrical or plumbing provisions, and connection scope | Reduces redesign and coordination issues during project planning |
The best layout depends on occupancy, equipment, access, and the expanded footprint available on site. A compact office may prioritize a clear desk area, entry access, and provision for power; a site accommodation unit may need defined sleeping, storage, and washroom areas. A sales or security unit may instead benefit from visibility and a convenient service opening. These are planning concepts, not included features or guaranteed layouts, so confirm the drawing and supply scope for the model you are considering.
Measure the ground area available in the fully opened configuration, not only the space needed to deliver the folded unit. Include room for the opening sequence, safe access, any required service connections, and installation work. Check ground conditions and the proposed support or foundation arrangement with the project team and supplier. If access is restricted by a gate, overhead obstruction, or neighboring structure, share those constraints before production or shipment planning.

For a useful layout review, mark the proposed door, windows, furniture, and service points on the supplier’s plan. Check that the expanded wings do not obstruct circulation or conflict with adjacent structures. If the unit must be relocated later, also ask how the folded configuration is prepared for transport and what equipment or site resources are needed. The supplier’s confirmed drawings and installation instructions should guide these decisions.
Compare suppliers against the same written brief rather than comparing product names alone. Specify the number of occupants, intended use, delivery destination, preferred layout, and any project-specific requirements. Then request dimensioned folded and expanded drawings, a full scope of supply, and an explanation of exclusions. This process makes it easier to identify whether two quotations describe comparable units.
Price depends on the confirmed configuration and commercial scope, so a headline price is meaningful only when the included items are clear. Layout changes, finishes, openings, service provisions, packaging, shipping destination, and installation responsibilities can all affect the quotation. Ask the supplier to separate the product price from freight or other services where applicable, and to state what is excluded. We do not recommend budgeting from an assumed standard specification when the final drawings are not yet approved.
Minimum order quantity (MOQ) and production lead time should be confirmed for the exact model and order quantity. Ask when the lead-time period begins, what approvals or deposits are required to start production, and whether the schedule changes with customization. Shipping duration and customs processing are separate from manufacturing time and should be checked for the destination. Have the supplier confirm the current terms in writing rather than relying on an estimate from a different configuration.
A dependable supplier should be able to explain the dimensions and provide documents that let your technical and procurement teams review the same configuration. Evaluate the clarity and completeness of the response, not only the quoted price. For a dual wing unit, particular attention should go to the opening arrangement, expanded footprint, transport configuration, and the boundary between factory scope and site work. Ask for clarification where a document uses ambiguous terms such as “width” without identifying its measurement points.
A 700mm wide dual wing expandable house can only be evaluated accurately when the 700 mm measurement is defined and the folded and expanded dimensions are documented. Choose a layout based on actual use, site access, and the finished footprint, then compare suppliers using the same specification and scope. Do not assume that a model label establishes usable interior dimensions, included services, or installation requirements. These details should be confirmed for the specific unit and project.
To begin a quotation discussion with Hongshun Guangju, share your intended application, order quantity, delivery destination, and any site constraints. Include the source of the 700 mm figure if you have it, and request drawings that identify the folded and expanded measurements. We can then discuss suitable layout and specification options and clarify the commercial information needed for your project evaluation.
