700 Wide Double Wing Expandable House Manufacturer: A Buyer’s Guide to Specifications, Customization, and Procurement

A 700 Wide Double Wing Expandable House is a transportable building whose side sections open out from a central structure to create a larger usable interior. The label “700 Wide” is not enough to establish the unit’s actual dimensions or capacity: buyers should confirm what the figure means and obtain a dimensioned drawing from the manufacturer. I recommend assessing the complete package—not only the folded and expanded size, but also materials, utilities, transport requirements, installation scope, and local compliance. This guide explains how to define your specification, compare suppliers, and request a quotation that can be evaluated against your project needs.

Key Takeaways

• Confirm exactly what “700 Wide” refers to; do not treat the product name as a complete dimensional specification.
• Request folded and expanded dimensions, layout drawings, material details, and a clear scope of supply before comparing prices.
• Provide site, transport, utility, and intended-use requirements so suppliers can assess whether their configuration is suitable.
• Compare quotations on equivalent specifications, including customization, packaging, delivery, and installation responsibilities.

Who This Guide Is For

This guide is intended for contractors, project owners, distributors, procurement teams, and other B2B buyers sourcing expandable accommodation or workspace. It is useful whether you are evaluating one unit for a site office or planning a larger project with repeated units. The product name alone does not indicate whether a particular configuration will meet your structural, operational, or regulatory requirements. I recommend treating the information below as a purchasing framework and confirming project-specific details with the manufacturer and relevant local professionals.

Understanding the Product and Its Specifications

How a double-wing expandable house works

A double-wing expandable house typically has a central section and two side sections that unfold to form additional enclosed floor area. The arrangement can be used for temporary or relocatable spaces such as accommodation, site offices, staff facilities, or project support areas. Actual layouts, opening mechanisms, and included equipment vary by supplier and model. Ask for drawings that show the unit in both its transport configuration and its fully expanded configuration.

Clarify the “700 Wide” designation

Do not assume that “700 Wide” means a specific overall width, module size, or transport dimension. Ask the supplier to define the term in writing and show the relevant measurement on a dimensioned drawing. Request dimensions in millimeters for the folded unit, expanded unit, internal clearances, doors, and any access routes that matter to your site. If your project uses a different measurement system, agree on one unit of measure across drawings, quotations, and purchase documents.

Review materials and included components

Confirm the specification of the structural frame, floor, wall and roof panels, windows, doors, seals, and connection hardware. Ask which elements are standard and which are optional, because product descriptions may not include every item needed for your intended use. For interior fit-out, specify requirements such as partitions, sanitary facilities, lighting, ventilation, or furniture rather than assuming they are included. Where a material or performance characteristic is important, request the supplier’s supporting documentation and confirm its applicability to the offered model.

Match the Configuration to the Application

Begin with how the space will be occupied and operated. A site office may need a different layout and utility package from staff accommodation, a temporary reception area, or a project welfare facility. Consider the number of users, privacy needs, storage, movement between rooms, and the expected duration of use. Also establish whether the unit will be moved after installation or remain in one location.

Site conditions can affect the choice as much as the floor plan. Check access for delivery vehicles, unloading equipment, ground preparation, drainage, and clearance for unfolding the side sections. Confirm what foundations or supports are required and who is responsible for preparing them. If the site has specific weather, insulation, fire-safety, accessibility, or building-code requirements, provide those requirements to the supplier early; suitability should be confirmed rather than presumed.

A Practical Selection Framework

1. Define the project brief

Prepare a written brief with the intended use, occupancy, destination country, site conditions, target delivery date, and expected operating period. List the functions the building must support, such as sleeping, working, washing, or storage. Separate essential requirements from preferred options so suppliers can identify feasible configurations and alternatives. This brief becomes the common basis for quotations and technical review.

2. Request comparable technical information

Ask each manufacturer for a dimensioned layout, a written specification, and an itemized scope of supply. The drawing should identify folded and expanded dimensions, room arrangement, openings, and utility connection points where applicable. Request details on installation steps, required equipment, and any work that must be completed by the buyer. If the information is incomplete, record the gap instead of assuming that two similarly named models are equivalent.

3. Confirm utilities and performance needs

State the required electrical supply, water and wastewater arrangements, heating or cooling expectations, and ventilation needs. As a practical example, list electrical loads in kilowatts (kW) and identify the supply voltage and frequency required at the destination. Ask the supplier to distinguish factory-installed equipment from equipment supplied separately or connected on site. Have qualified local professionals review utility and safety requirements where required.

4. Check transport and installation responsibilities

Request the packed or transport configuration, gross weight, lifting points, packaging method, and any handling instructions available for the offered model. Confirm the delivery location and clarify whether the quotation covers export packing, inland transport, ocean freight, customs-related services, unloading, or installation. These items can materially change the landed project cost. The buyer and supplier should document who is responsible for each stage before an order is placed.

Customization, Pricing, MOQ, and Lead Time

Customization may cover the internal layout, doors and windows, finishes, insulation options, electrical fit-out, sanitary equipment, and branding. Availability depends on the manufacturer’s design and production capability, so request a written confirmation for every non-standard feature. Ask whether a requested change affects dimensions, packing, weight, price, or delivery schedule. For project-critical changes, obtain approval drawings before production.

There is no reliable universal price, minimum order quantity (MOQ), or lead time for every 700 Wide Double Wing Expandable House. These depend on the selected configuration, order quantity, customization, destination, production schedule, and shipping arrangements. Ask suppliers to quote the same specification and identify the validity period, payment terms, production milestones, and estimated shipping basis. For planning, request a lead-time estimate in calendar days and ask which events start and stop that estimate.

Supplier Evaluation Checklist

Assess documentation and communication

Evaluate whether the supplier can explain the product dimensions, configuration, included items, and limitations clearly. Check that the company’s quotation, drawings, and specification refer to the same model and revision. Ask who will handle technical questions, order updates, packing information, and after-sales requests. Clear answers and consistent documents make it easier to manage procurement risk, although they do not replace independent verification where needed.

Compare quotations on an equal basis

Use a line-by-line comparison rather than selecting solely by the headline price. Compare the frame and panel specifications, layout, optional equipment, packing, delivery scope, installation support, warranty terms, and exclusions. Ask the supplier to identify any assumptions that could affect the final cost. If an offer is substantially different from another, first check whether the scope or specification is also different.

Common Procurement Mistakes to Avoid

• Relying on the product name: confirm every critical dimension and configuration on a drawing.
• Comparing incomplete quotations: align specifications, included equipment, delivery scope, and exclusions first.
• Leaving site requirements until late: share access, ground, utility, and local compliance needs before finalizing the order.
• Assuming custom features are standard: list every requested option and obtain written acceptance.
• Ignoring installation responsibilities: agree on unloading, unfolding, connections, and site preparation before shipment.
