A 700 Double Wing Expandable Container House is a transportable building concept that expands from a compact, folded configuration into a wider usable space by opening its side wings. It may suit projects that need quickly deployable accommodation, offices, site facilities, or other modular spaces, but the name “700” alone does not confirm the unit’s dimensions, layout, materials, or included equipment. Before buying, compare the supplier’s drawings and specifications with your site, delivery route, intended use, and local requirements. At Hongshun Guangju, we recommend confirming these details before requesting a final quotation.
This guide is for contractors, property developers, project managers, distributors, and other B2B buyers considering an expandable container house for a defined project. It is useful whether you need a single unit for a temporary site or are evaluating several units for a larger deployment. The right choice depends on how the building will be used, where it will be installed, and what your logistics and compliance requirements allow. Buyers should establish these conditions before comparing supplier prices.
An expandable house is transported in a folded state and opened at the destination to create additional floor area. In a double-wing design, side sections extend from the central structure, but the exact folding system and connection details can vary by manufacturer. Ask for drawings that show both the transport configuration and the fully expanded layout. Confirm which components are factory-fitted and which require work on site.
The word “700” should not be treated as a verified measurement unless the supplier defines it in writing. It may identify a product series or configuration rather than a specific length, area, or capacity. Ask the supplier to state the exterior dimensions in millimeters (mm), the usable internal dimensions in millimeters (mm), and the total expanded floor area in square meters (m²). These measurements let your team check the design against site plans and operational needs.
Expandable units can differ in frame construction, wall-panel composition, roof design, flooring, glazing, and interior finish. A product description may use broad terms such as “steel frame” or “insulated panel,” so request the material specifications and construction details behind those terms. Confirm whether the quoted configuration includes insulation, internal lining, doors, windows, and basic electrical provisions. Do not assume that an item shown in a product image is included in the price.
For example, if your site plan reserves a 6 m × 3 m installation area, that is a planning input—not a claim about the dimensions of a 700 model. Compare the reserved area with the supplier’s actual expanded drawings and allow for access, maintenance, and safe opening of the wings. Similarly, provide your project’s expected electrical load in kilowatts (kW) so the supplier can clarify what the unit includes and what must be connected separately. These project figures should be confirmed by the relevant design and site teams.
Potential applications include construction-site offices, temporary accommodation, security or reception spaces, and other locations where a deployable room is useful. Suitability depends on factors such as occupancy, climate, duration of use, access to utilities, and local building or fire requirements. A layout designed for an office may not meet the privacy, sanitation, or service needs of accommodation. Define the intended use before selecting finishes and equipment.
For remote or constrained sites, transportation and installation may influence the decision as much as the interior layout. Check the folded dimensions, delivery access, lifting or handling requirements, ground preparation, and the space needed to expand the unit. Ask the supplier to identify the equipment and personnel required for installation, and clarify whether these are included or arranged locally. Confirm site readiness before scheduling delivery.
Write down the number of units, intended use, required layout, target installation date, climate conditions, and expected operating period. Identify local rules that may apply to temporary or modular buildings, including permitting, fire safety, electrical work, and accessibility where relevant. Requirements vary by project location, so consult your local project professionals or authorities. Share the applicable requirements with each supplier at the enquiry stage.
With competitive price and timely delivery, Hongshun Guangju sincerely hope to be your supplier and partner.
Request a dimensioned plan, elevation drawings, and a list of included and optional items. Compare the transport configuration with the delivery route, and compare the expanded configuration with the available site footprint. Ask how the wings are supported and connected, and what preparation is required before opening the unit. If a requirement is unclear, resolve it in writing rather than relying on a verbal summary.
Ask for a quotation that separates the unit price from packaging, transport, export or import charges where applicable, installation, and optional equipment. The total project cost may depend on destination, quantity, customization, shipping arrangement, and site work. Request the estimated production and delivery schedule in calendar days, along with the assumptions behind it; treat the schedule as supplier guidance rather than a guarantee unless the purchase terms say otherwise. Compare quotations using matching specifications and delivery terms.
Minimum order quantity (MOQ) and customization options are supplier- and project-dependent. Ask whether the quoted price applies to one unit or a specific order quantity, and whether design changes affect MOQ, cost, or production timing. Provide the delivery destination and required configuration when requesting a quote. This helps suppliers return a more useful and comparable proposal.
A reliable supplier response should explain what the product includes and identify the information still needed to confirm suitability. Evaluate the clarity and consistency of the drawings, specification sheet, quotation, and delivery terms. Ask how quality checks are handled and what inspection information can be provided for your order; do not assume a particular certification or test result unless the supplier supplies verifiable documentation. For project-specific compliance, confirm requirements independently with the relevant local professionals.
One common mistake is choosing by model name or price without checking the complete dimensions and configuration. Another is assuming that “expandable” means the unit can be installed on any surface or without local preparation. Buyers can reduce these risks by reviewing drawings, confirming foundation or ground requirements, and agreeing on the installation scope before placing an order. Keep approved specifications and changes in the purchase documentation.
A second risk is overlooking the difference between a product quotation and a delivered, operational project. Freight, site access, utility connections, local installation labor, and permitting may sit outside the product price. Ask the supplier to state exclusions and identify which party is responsible for each task. Use the project schedule to coordinate production, transport, site preparation, and installation.
At Hongshun Guangju, we encourage buyers to share their application, destination, quantity, target schedule, and preferred configuration when enquiring about a 700 Double Wing Expandable Container House. This gives our team a basis for discussing available specifications, customization possibilities, and quotation scope. We can clarify which details need confirmation for your project, including dimensions, materials, included fittings, packaging, and delivery arrangements. Final availability, pricing, and timing should be confirmed in a project-specific quotation.
A 700 Double Wing Expandable Container House may be a practical option when a project needs a transportable structure that opens into a larger usable space, but suitability cannot be established from the model name alone. Confirm the folded and expanded dimensions, construction and service specifications, application requirements, site conditions, and complete commercial scope. Then compare suppliers using the same written specification and delivery assumptions. To move forward, prepare your project brief and request dimensioned drawings and a detailed quotation from Hongshun Guangju for review.
