Custom 700 Wide Dual Wing Expandable House: Dimensions, Layout, and Customization Guide

A custom 700 wide dual wing expandable house is a factory-made modular building that uses a central container-style section with two fold-out side wings. In most project discussions, “700 wide” refers to a nominal width designation, but the exact unfolded and folded dimensions must be confirmed in the technical drawing because specifications can vary by model. At Hongshun Guangju, we help B2B buyers evaluate the available footprint, internal layout, materials, utilities, and delivery requirements before production.

This guide explains how the 700 wide dual wing expandable house works, which dimensions matter, how to choose a suitable layout, and what information to prepare for a quotation. It is intended for contractors, distributors, developers, site operators, and project owners who need a transportable building with a larger usable area than a standard container unit. Because local building codes, wind loads, insulation requirements, and transport restrictions differ, final specifications should always be confirmed for the intended destination.

Who This Guide Is For

This guide is useful for buyers comparing expandable houses for worker accommodation, temporary offices, site facilities, classrooms, clinics, guard stations, and small commercial spaces. It is also relevant to importers and construction companies that need a repeatable product platform with project-specific modifications. I recommend using the guide before requesting a formal quotation, especially when the project involves multiple units or overseas shipment.

How the 700 Wide Dual Wing Expandable House Works

The house is normally shipped in a compact folded condition and opened at the installation site. Its central structure provides the main structural and service zone, while the two side wings extend outward to create additional floor area. This configuration can offer a more efficient site footprint than using several independent container units, although the actual usable area depends on the selected dimensions, wall thickness, furniture arrangement, and circulation space.

The dual-wing design is especially useful when the buyer wants separate functional zones within one connected building. For example, one wing can be used as a bedroom or office and the other as a kitchen, washroom, storage area, or meeting room. The center section can then serve as a living area, entrance zone, corridor, or shared workspace.

Dimensions Buyers Should Confirm

Folded Transport Dimensions

Folded dimensions determine whether the unit can be loaded, transported, lifted, and positioned efficiently. Buyers should request the exact folded length, width, height, gross weight, lifting points, and packing method rather than relying only on the product name. A difference of even a few centimeters can affect container loading, road transport, crane selection, and site access.

The “700 wide” designation should therefore be treated as a product reference, not as a substitute for a confirmed drawing. At Hongshun Guangju, we can review the destination port, delivery route, unloading method, and installation conditions so that the proposed model matches the logistics plan. The buyer should also check whether local transport rules limit the load height or width.

Expanded Dimensions and Usable Area

Expanded dimensions define the final building footprint and the amount of usable interior space. The key measurements include the overall external length and width, internal clear height, wall thickness, door and window positions, and the opening radius required by the wings. The final layout should reserve sufficient clearance for furniture, plumbing access, electrical equipment, and safe movement between rooms.

When comparing quotations, I suggest separating three measurements: external footprint, internal usable area, and service area occupied by cabinets or equipment. These figures may not be identical, and comparing only the external size can lead to an inaccurate assessment of value. The manufacturer should provide a dimensioned floor plan and, where necessary, an elevation or 3D layout for review before production.

Layout Options for Different Applications

Accommodation and Dormitory Layout

For accommodation, the layout should prioritize sleeping capacity, ventilation, privacy, and bathroom access. A common planning approach is to place beds and storage against the side walls while keeping the center passage clear. Buyers should decide whether the unit requires a private bathroom, a shared washroom arrangement, a kitchenette, or a separate utility room.

For a worker accommodation project, I recommend confirming the intended number of occupants before selecting furniture. A layout designed for short-term sleeping may not provide adequate storage or common space for longer stays. The final design should also consider emergency access, local occupancy rules, and the location of fire safety equipment where applicable.

Office, Classroom, and Site Facility Layout

Office and classroom applications require different circulation patterns from residential use. The two wings can be arranged as work zones, meeting rooms, storage spaces, or teaching areas, while the center provides reception or shared circulation. Window placement, data cable routes, power outlets, and lighting positions should be planned together rather than added after the layout is approved.

For a site office, buyers may prefer a simple open layout with a compact pantry and washroom. For a classroom or training room, daylight, desk spacing, air movement, and accessible entry are more important. I recommend providing the planned furniture arrangement to the supplier because it can reveal conflicts between doors, cabinets, windows, and fold-out components.

Clinic, Retail, and Service Applications

A clinic may need a reception zone, consultation room, hand-washing facilities, storage, and controlled circulation. A small retail or service unit may need a sales counter, display walls, product storage, and a customer entrance with suitable visibility. These applications often require more detailed electrical, plumbing, ventilation, and finish specifications than a basic accommodation unit.

Not every project should use the same standard floor plan. If the unit will receive public visitors, the buyer should verify accessibility, local fire requirements, sanitary provisions, and any permit obligations before ordering. Hongshun Guangju can use the buyer’s room schedule and equipment list as the basis for a project-specific layout discussion.

Customization Options to Evaluate

Structure, Envelope, and Interior Materials

Customization can include the steel frame arrangement, roof and floor construction, wall panels, insulation type, internal partitions, doors, windows, flooring, ceiling finish, and exterior color. Material selection should be based on the climate, expected service period, transport conditions, cleaning needs, and budget. Buyers should request the construction description for each layer instead of evaluating a wall only by its surface appearance.

In hot or cold regions, insulation and ventilation deserve early attention because they influence comfort and operating costs. In wet or coastal environments, corrosion protection, roof drainage, sealing details, and maintenance access may become more important. These requirements should be written into the technical specification so that the quotation is clear and comparable.

Utilities and Equipment

Electrical customization may cover distribution boards, sockets, interior lighting, exterior lights, emergency lighting provisions, and equipment connection points. One practical data point to confirm is the planned electrical load in watts; for example, a buyer may specify a preliminary 3,000-watt load for a small office, but the final value must be calculated from the selected appliances and local electrical system. Plumbing layouts should identify water inlet, drainage outlet, water heater position, bathroom fixtures, and maintenance access.

Heating, ventilation, and air-conditioning provisions should also be discussed before fabrication. Window quantity and opening type can affect natural ventilation, while air-conditioning locations can affect wall reinforcement and cable routing. I recommend sending an equipment schedule with voltage, frequency, power, dimensions, and installation requirements to reduce later modifications.

Buyer Selection Framework

Step 1: Define the Project Use

Start by identifying the building function, number of users, expected occupancy duration, site climate, and required rooms. Then list the furniture and equipment that must fit inside the unit. This step prevents buyers from selecting a footprint first and discovering later that the intended layout cannot accommodate the actual operation.

Step 2: Confirm Site and Logistics Conditions

Measure the access road, gate width, ground condition, available installation area, crane or forklift access, and utility connection points. Also confirm whether the site requires foundations, leveling supports, drainage works, or anchoring. The expandable house may be faster to install than a conventional building, but site preparation is still necessary for safe and stable use.

Step 3: Compare Technical Quotations

Compare quotations using the same checklist: folded dimensions, expanded dimensions, materials, insulation, windows, doors, flooring, electrical system, plumbing, accessories, packing, and delivery scope. Ask whether the price includes internal finishes, sanitary fixtures, installation guidance, and spare parts. A low initial price may not represent a lower project cost if important items are excluded.

Step 4: Approve Drawings Before Production

Before manufacturing, approve the floor plan, elevations, color scheme, door and window schedule, utility layout, and packing arrangement. Check every room dimension against the furniture and equipment list. Any change made after production begins may affect cost, lead time, or structural coordination, so written confirmation is valuable for both buyer and supplier.

Pricing, MOQ, and Lead-Time Considerations

The final price depends on the selected size, material specification, interior finish, utility package, quantity, packaging, and delivery terms. A standard configuration is usually easier to quote than a highly customized unit, while repeated orders may support more consistent production planning. Buyers should ask for a line-item quotation that separates the house, optional equipment, packaging, shipping-related items, and installation support.

Minimum order quantity can vary according to the model and customization level. For a one-unit project, a buyer should confirm whether the supplier accepts a sample or trial order and whether special tooling or design charges apply. Lead time should be confirmed after the technical specification and drawings are approved, rather than estimated from the first inquiry alone.

Supplier Evaluation Checklist

• Can the supplier provide folded and expanded dimension drawings?
• Are the frame, wall, roof, floor, and insulation specifications clearly listed?
• Can the supplier customize room layouts, utilities, finishes, and branding?
• Are packing, lifting, installation guidance, and spare parts explained?
• Can the supplier review destination-country requirements without claiming approvals it has not verified?
• Is there a clear process for drawing approval, production updates, inspection, and shipment coordination?
