If you are evaluating a 10ft Double Wing Expandable House, I recommend starting with three questions: what does “10ft” describe, how much space is created after expansion, and what site work is required before delivery. In most product descriptions, 10ft refers to the nominal width of the transportable central unit, equal to approximately 3.05 meters; the final open footprint depends on the wing dimensions and the manufacturer’s design. A complete purchase assessment should therefore review drawings, folded and expanded dimensions, materials, utilities, installation responsibilities, packaging, and landed cost rather than relying on the product name alone.

As a manufacturer and export supplier, Hongshun Guangju can help B2B buyers compare configurations and prepare a practical quotation request. I treat the price as a combination of the house structure, interior fit-out, optional equipment, transport, site preparation, installation, and local compliance requirements. The safest buying decision is the one based on a written technical specification and a clear division of responsibilities.
This guide is intended for contractors, developers, distributors, project owners, emergency housing planners, camps, and other commercial buyers comparing expandable modular accommodation. It is especially useful when the buyer needs a compact unit for transport but requires more usable floor area after installation. I also recommend it to importers who need to understand which items should be confirmed before requesting a factory quotation.
The guide does not replace local engineering approval, building permits, or a site-specific structural review. Wind, snow, seismic conditions, fire regulations, thermal requirements, and utility standards vary by destination. Before placing an order, I suggest asking a qualified local professional to confirm whether the proposed configuration is suitable for the intended site.
A 10ft Double Wing Expandable House is a prefabricated modular building designed for compact transportation and faster on-site deployment. It normally consists of a central frame with two foldable or expandable wing sections that open outward to create a larger interior layout. The phrase “double wing” describes the two side extensions, while “10ft” usually identifies a nominal transport width and must be verified against the supplier’s technical drawing.
After expansion, the building can be configured for accommodation, temporary offices, classrooms, site facilities, guard rooms, clinics, retail points, or worker welfare areas. The exact use depends on the internal layout, insulation system, doors and windows, sanitary equipment, electrical package, and local approval requirements. I recommend selecting the application first, because a dormitory, office, and medical-use layout do not have identical ventilation, privacy, plumbing, or fire-safety needs.
The first specification to request is a dimension sheet showing the folded length, folded width, folded height, expanded length, expanded width, usable floor area, total weight, lifting points, and container or truck-loading method. A 10ft nominal width is approximately 3.05 meters, but this does not tell you the complete expanded footprint. Because the two wings may differ by design, I would not estimate the installed area without reviewing the supplier’s drawing.
Common construction decisions include the main steel frame, roof and floor structure, wall sandwich panels, insulation core, windows, doors, floor finish, ceiling, and interior services. Buyers should compare the panel core and thickness, coating or corrosion protection, drainage details, hardware quality, and replacement availability rather than comparing only the external appearance. If the house will be shipped to a humid, coastal, cold, or high-wind region, these environmental conditions should be stated before production.
| Specification Area | What I Recommend Confirming |
|---|---|
| Dimensions | Folded and expanded sizes, clear height, floor area, and tolerance |
| Structure | Frame material, connection method, loading assumptions, and lifting points |
| Envelope | Wall and roof panel type, insulation, waterproofing, and finish |
| Utilities | Electrical voltage, plumbing arrangement, lighting, outlets, and HVAC provision |
| Delivery | Folded weight, package dimensions, unloading equipment, and installation tools |
For electrical planning, I ask buyers to confirm the destination voltage and frequency before manufacturing, rather than assuming a standard package. As a simple technical reference, a 220–240 V supply is common in many markets, but the correct specification must follow the project location. Similarly, a proposed 3–5% contingency in the buyer’s internal budget can help cover minor site or procurement changes, but it is a planning recommendation and not a guaranteed cost percentage.
Installation begins before the unit arrives. The buyer normally needs a level, accessible foundation or support system, a clear unloading route, suitable lifting equipment, drainage arrangements, and prepared utility connection points. I recommend confirming whether the quoted supplier scope includes unloading, wing deployment, sealing, internal finishing, electrical connection, plumbing, and commissioning.

Installation time depends on the degree of factory completion, site readiness, crew experience, weather, lifting equipment, and local utility work. For planning discussions, I ask the supplier to state whether the quoted lead time covers factory production only or also installation and commissioning. A short factory lead time does not automatically mean a short project schedule if the foundation, permits, or transport route are unfinished.
The purchase price of the house is only one part of the project budget. I divide the total cost into six categories: the base unit, selected options, packaging and export preparation, inland and international transport, site preparation and installation, and local taxes or compliance costs. This structure makes supplier quotations easier to compare and helps prevent a low initial price from hiding important exclusions.
MOQ and lead time should be discussed together with configuration and destination. A single customized unit may require different engineering and packaging work from a repeat order of multiple standardized units, while a larger order may require production scheduling and coordinated shipping. Instead of asking only for the lowest unit price, I suggest requesting a quotation valid for a stated quantity, Incoterm, destination port, configuration, and delivery date.
I recommend using a four-stage selection framework: application, technical fit, total cost, and supplier reliability. First, define the number of occupants, room function, climate, expected service life, mobility requirements, and whether the building is temporary or semi-permanent. Second, match those needs with the structural system, insulation, utilities, finishes, and local standards.
Third, compare the total delivered and installed cost instead of the factory price alone. Fourth, evaluate whether the supplier can provide drawings, option lists, packing information, installation guidance, spare parts, quality-control records, and responsive export communication. Hongshun Guangju can support this process by discussing configuration requirements, preparing product information for quotation, and clarifying which items are included or excluded in the proposed supply scope.
The most common mistake is treating “10ft” as the final installed size. Another is comparing two quotations with different interior packages, transport terms, or installation scopes. Buyers should also avoid approving production before confirming foundation tolerances, lifting access, utility locations, destination voltage, and local regulatory requirements.
A further risk is selecting finishes before defining the operating environment. Coastal areas, cold climates, heavy rainfall, and high-traffic commercial use can require different corrosion protection, insulation, waterproofing, flooring, or hardware choices. I recommend recording every decision in a signed technical specification so that the quotation, drawings, production, and inspection refer to the same version.
A 10ft Double Wing Expandable House can be a practical modular solution when transport efficiency and expanded usable space are both important. The right purchase decision depends on verified folded and expanded dimensions, suitable materials, a realistic installation plan, and a complete landed-cost calculation. The nominal 10ft size, two-wing configuration, and approximately 3.05-meter conversion are useful starting points, but they are not substitutes for project drawings.
To move forward, prepare your destination, quantity, intended application, required layout, utilities, climate conditions, delivery location, and target schedule. Ask Hongshun Guangju for a configuration-based quotation with drawings, specifications, packing details, lead time, MOQ, and clearly separated optional costs. With this information, I can help you compare the 10ft Double Wing Expandable House against your site requirements and develop a more reliable procurement plan.
