700mm Expandable Container House: Dimensions, Layout, and Buying Guide

A 700mm expandable container house is a modular building described with a 700mm dimension, but that figure alone does not define the unit’s full size. Before comparing products, ask the supplier to confirm exactly what the 700mm refers to, such as a wing extension, a folded component, or another dimension. At Hongshun Guangju, we recommend evaluating the closed transport size, expanded footprint, internal usable area, layout, and site requirements together. This guide explains what to request and how to assess whether a double-wing expandable house suits your project.

Key Takeaways

• Confirm in writing what the stated 700mm measures; do not use it as a substitute for a complete product dimension sheet.
• Request both folded and expanded dimensions, plus an internal layout showing doors, windows, partitions, and service points.
• Check transport access, installation space, foundations, local requirements, and utility connections before ordering.
• Compare suppliers using the same configuration and a written scope of supply, not headline dimensions alone.

Who This Guide Is For

This guide is for contractors, distributors, developers, project buyers, and organizations considering expandable container buildings for temporary or longer-term use. It is especially useful when a specification mentions “700mm” but does not clearly explain how that measurement relates to the complete house. The goal is to help you prepare a clear inquiry and identify details that need confirmation before production, shipment, or site preparation.

Understanding the Dimensions

What Does “700mm” Mean?

The product name is not a complete technical specification. A 700mm figure could refer to an individual wing’s extension, a component dimension, or another product-specific measurement, so buyers should not assume which interpretation is correct. Ask the manufacturer to mark the 700mm dimension on a drawing and state whether it applies to one side, both sides, or a different part of the structure.

If a supplier confirms that each of two wings adds 700mm to the building width, the theoretical increase would be 1,400mm in total. That is a conditional calculation, not a verified dimension for every 700mm model. The actual expanded width may depend on the base structure, wall construction, connection details, and the supplier’s design. Use the approved product drawing—not the product name—to plan the site.

Request Both Folded and Expanded Measurements

A useful dimension schedule should show the folded length, width, and height, as well as the expanded external dimensions. It should also provide internal clear dimensions, because wall thickness and partitions affect usable floor area. Ask for the measurement units, dimension tolerances if available, and a drawing that identifies which measurements are external and which are internal.

For illustration only, a hypothetical expanded footprint of 6,000mm by 5,900mm would equal 35.4m² before accounting for internal wall thickness or unusable areas. This example is a calculation, not a Hongshun Guangju product specification. Request the footprint and net usable area for the exact configuration you intend to buy.

Layout and Configuration Options

A double-wing format can create additional floor area when the wings are opened, but the best layout depends on how the building will be used. A site office may prioritize a work area, storage, and a clear entrance route, while accommodation may require separate sleeping, living, and sanitary zones. A reception or sales space may need a more open arrangement and convenient visitor access.

Match Rooms to the Project

Prepare a simple room schedule before requesting a quotation. List each intended function, the number of occupants or users, required furniture, and any privacy or access needs. Then ask the supplier to show doors, windows, partitions, and equipment positions on the proposed floor plan.

Also confirm whether the quoted layout includes sanitary equipment, kitchen fixtures, lighting, electrical components, insulation, or interior finishes. These items can vary by order and destination, so a room shown on a drawing should not be assumed to include every fixture. A written inclusion list helps you compare proposals on an equivalent basis.

Materials and Key Specifications to Review

Expandable houses can differ in their structural framing, wall and roof panels, floor construction, openings, and finish options. Do not select a unit based on a material label alone: ask for the material description, thickness where relevant, finish, and intended application. The appropriate specification depends on climate, occupancy, transport conditions, expected use, and local building requirements.

For a procurement review, request a technical package covering the following information:

Hongshun Guangju contains other products and information you need, so please check it out.

• Folded and expanded dimensions, with a clearly identified 700mm measurement.
• Structural frame and panel descriptions, including available material or finish options.
• Floor plan, elevation drawings, door and window locations, and internal clear dimensions.
• Electrical, plumbing, insulation, and interior fit-out scope, where applicable.
• Product weight and packing details for transport planning.
• Foundation, leveling, connection, and installation guidance available for the selected model.

How to Select a Model for Your Application

1. Define the Site and Use

Start with the intended function, expected occupancy, length of use, climate exposure, and required utilities. Measure the installation area and check access for the delivery vehicle, unloading equipment, and any required assembly work. Confirm local rules with the relevant project professionals or authorities; requirements can vary by location and intended use.

2. Compare the Transport and Operating Footprints

The folded unit must be compatible with the selected shipping and delivery route, while the expanded building must fit the prepared site. Ask your freight provider to review the package dimensions and weight before finalizing logistics. Separately, confirm that the site provides enough space to open the wings and complete installation safely.

3. Review the Drawing and Scope

Check that the quotation, floor plan, and technical schedule describe the same configuration. Verify the orientation of the wings, entry points, window positions, partitions, and service connections. If any detail is missing or ambiguous, request a revised drawing before approving the order.

4. Compare Total Procurement Requirements

Compare the product price alongside packing, shipping, unloading, foundation preparation, installation, and any locally required work. Ask each supplier to state the minimum order quantity, production lead time, payment terms, packing method, and what could change the schedule. These details are project-specific, so obtain a written quotation rather than relying on general estimates.

Pricing, MOQ, and Lead Time

The final price can depend on dimensions, layout, materials, interior fit-out, quantity, packing, and destination. A custom electrical or sanitary package may be quoted differently from a basic shell, and logistics costs are influenced by route and shipment arrangements. For an accurate comparison, send suppliers the same project brief and request itemized inclusions and exclusions.

Minimum order quantity and production lead time should also be confirmed for the selected configuration. Ask when the lead-time period begins, what approvals or deposits are required, and how changes after drawing approval are handled. Avoid treating a general lead-time statement as a commitment unless the terms are documented in the quotation or order agreement.

Supplier Evaluation Checklist

A suitable supplier should be able to explain the product configuration and provide documentation that matches the proposed order. During evaluation, ask whether the supplier can clarify the 700mm dimension, prepare a project-specific layout, and state which components are included. You can also request packing details, installation guidance, and a clear process for handling specification questions.

At Hongshun Guangju, we support B2B buyers by discussing the intended application, reviewing dimension and layout requirements, and clarifying configuration details for quotation. Share your target footprint, site location, intended use, quantity, and required fit-out so we can assess the request against the available product options. Final specifications should be confirmed in the approved drawings and order documents.

Common Buying Mistakes to Avoid

• Assuming that “700mm” describes the total expanded width without a dimensioned drawing.
• Planning only around the expanded footprint and overlooking folded transport dimensions.
• Comparing quotations with different room layouts, materials, or included equipment.
• Leaving foundations, utility connections, local approvals, or unloading arrangements until after ordering.
• Relying on verbal descriptions when important specifications can be recorded in writing.

Conclusion: What to Do Before You Buy

A 700mm expandable container house may suit a project when its verified dimensions, layout, transport requirements, and scope match the intended use. The key first step is to establish exactly what the 700mm measurement refers to, then evaluate the complete folded and expanded dimensions using an approved drawing. Confirm the layout, materials, included fit-out, site preparation, logistics, MOQ, and lead time before committing.

To request a project-specific review from Hongshun Guangju, prepare your target footprint, site and delivery location, intended application, quantity, and preferred interior configuration. With those details, we can discuss suitable options and clarify the specifications that should be confirmed for your order.
