700 Wide Expandable Site Office Buying Guide: Dimensions, Setup, and Specifications

A 700 Wide Expandable Site Office is a transportable workspace designed to open out at the destination, creating more working area than its closed transport configuration. The term “700 wide” may refer to a nominal dimension, but buyers should confirm whether the figure means 700 cm, 7.0 m, or another model designation before planning transport or installation. The right purchase depends on verified closed and expanded dimensions, site access, foundation conditions, utilities, and the specification of the actual unit.

You can find more information on our web, so please take a look.

This guide explains how to check those details, compare configurations, and prepare a supplier enquiry. At Hongshun Guangju, we recommend reviewing a dimensioned drawing and a written specification before confirming an order, because product names alone do not define the final layout or site requirements.

Key Takeaways

• Confirm what “700 wide” means and request both closed and expanded dimensions in a consistent unit.
• Plan transport and installation around the unit’s packed footprint, lifting points, access route, and required working space.
• Specify the intended use, occupancy, climate, utilities, finishes, and local compliance requirements before comparing quotations.
• Ask for a project-specific drawing, scope of supply, lead-time estimate, and clear allocation of site-preparation responsibilities.

Who This Guide Is For

This guide is intended for contractors, construction-site managers, project procurement teams, developers, and distributors evaluating an expandable office for a temporary or relocatable project. It is also useful for buyers who need a site office that can be transported in a compact form and opened into a larger workspace. Requirements differ between a single project office, a multi-person administration room, and a unit used for meetings or staff facilities.

Before requesting a quotation, identify who will use the office and what activities will take place inside. A workspace for desks and document storage may need a different layout, lighting plan, and number of electrical outlets from a meeting room or site reception area. Defining the use early helps suppliers recommend relevant options rather than quote an unsuitable standard arrangement.

Understanding the Dimensions and Configuration

Clarify the “700 Wide” designation

Do not treat “700 wide” as a complete dimensional specification. If the designation is intended to mean 700 cm, the conversion is 7.0 m, but that interpretation must be confirmed with the supplier for the exact model. Ask whether the stated width describes the opened unit, the closed transport module, or a product-series name.

Request a drawing that labels external and internal dimensions in millimetres or metres. The document should show the unit in both transport and deployed configurations, including the direction in which each wing opens. Also confirm whether dimensions include steps, roof projections, canopies, or other optional parts.

Check usable space, not only the outside footprint

External dimensions help determine site fit, while internal dimensions indicate how the room can be furnished. Ask for the clear floor area after accounting for wall thickness, partitions, door swings, and built-in items. If the office will hold desks, allow the supplier or your project team to mark furniture positions on the proposed layout before production.

Transport dimensions matter just as much as expanded dimensions. Confirm the closed width, height, and length, as well as the loaded transport configuration and any packaging that affects the overall envelope. Your logistics provider should use those values to check vehicle suitability, route restrictions, site access, and unloading arrangements.

Types, Materials, and Specification Options

Expandable site offices can differ in frame construction, wall and roof assemblies, flooring, glazing, doors, and interior fit-out. The appropriate combination depends on climate, expected use, transport frequency, and project duration. Because material names do not establish performance on their own, request descriptions of the proposed layers, thicknesses, finishes, and maintenance requirements.

Structure and envelope

Ask what the main frame is made from and how the walls, roof, and floor are assembled. For projects exposed to heat, cold, rain, or wind, request the relevant design information and clarify which performance values are available for the offered configuration. Do not assume that a standard unit has a particular insulation level, weather rating, or structural rating unless it is stated in the quotation or technical documents.

Interior, doors, windows, and services

Review the planned number and position of doors and windows, along with flooring, ceiling, interior lining, and any partitions. Confirm whether lighting, air conditioning, sockets, wiring, furniture, and plumbing are included or supplied separately. Electrical requirements vary by destination, so provide the project’s required supply voltage and plug or connection standard rather than relying on a generic product description.

Match the Office to the Application

For a construction administration office, prioritize a practical desk layout, document storage, lighting, ventilation, and secure access. For a meeting space, check the usable seating area and the position of doors and windows so that circulation remains clear. If the unit will serve as a reception point or a combined office and welfare area, discuss partitions and service requirements before finalizing the layout.

Site conditions can change the specification. A remote project may need a different utility plan from a site with established power and water connections, while a frequently relocated unit places greater emphasis on transport and repeated deployment arrangements. Share the intended project duration, expected relocation frequency, climate, and available site services with the supplier.

Selection Framework: From Site Review to Order

1. Define the use. Record the intended occupants, activities, furniture, and any separate rooms required.
2. Verify dimensions. Obtain closed and expanded drawings, internal clear dimensions, door positions, and opening direction.
3. Check the site. Confirm access for delivery and lifting, ground conditions, drainage, working space, and utility connection points with the project team.
4. Set the specification. List required materials, finishes, insulation or climate-control needs, electrical provisions, and optional equipment.
5. Compare complete quotations. Check what is included, what is excluded, packaging, delivery terms, installation responsibilities, and the stated production schedule.

Use one set of project requirements when requesting offers from multiple suppliers. This makes it easier to compare like-for-like proposals and identify where a lower price reflects a different fit-out, material, or delivery scope. Request any assumptions in writing, especially those concerning foundations, unloading, assembly, and connections to site utilities.

Setup Requirements and Common Buying Mistakes

Before delivery, coordinate the prepared location with the supplier’s installation guidance and your site team. The ground should be suitable for the unit’s support arrangement, and the opening area should be free of obstructions. Confirm how the unit is lifted, what equipment is required, and who is responsible for placing, opening, leveling, and connecting it.

A common mistake is planning only for the deployed footprint and overlooking the delivery route or closed transport size. Another is assuming that “expandable” means all setup work, utilities, and commissioning are included in the purchase. Buyers should also avoid treating a catalogue image as a binding layout; request a drawing that reflects the exact doors, windows, partitions, and options being ordered.

Do not overlook local requirements. Permits, temporary-structure rules, electrical connections, fire-safety provisions, and accessibility obligations vary by project and location. Ask the relevant local professionals or authorities to confirm applicable requirements, and provide those requirements to the supplier before production where they affect the design.

Pricing, MOQ, and Lead Time

The price of a 700 Wide Expandable Site Office depends on the confirmed dimensions, structure, interior specification, options, order quantity, packaging, and delivery destination. A quotation should separate the unit price from transport, installation, and other project-specific costs where applicable. Do not compare headline prices without checking whether the same scope and configuration are being offered.

Minimum order quantity and production lead time are supplier- and project-dependent. Ask whether the quoted schedule begins after drawing approval, deposit, or completion of another order requirement, and confirm how customization may affect timing. For international orders, also clarify packaging, shipping terms, export documentation, and who arranges unloading at the destination.

Supplier Evaluation Checklist

A reliable buying process depends on clear technical communication as well as product selection. Before placing an order, check that the supplier can provide a project-specific drawing, a written bill of specification, and a defined list of inclusions and exclusions. Confirm how design changes are reviewed and approved so that the production configuration matches the agreed documents.

• Are closed, expanded, and internal dimensions clearly identified?
• Does the drawing show opening direction, doors, windows, and optional partitions?
• Are materials, finishes, electrical provisions, and optional equipment specified?
• Are delivery, lifting, installation, and utility responsibilities clearly assigned?
• Are price, MOQ, payment terms, and estimated lead time stated for the requested configuration?

Hongshun Guangju can discuss the intended application and help buyers organize the information needed for a suitable expandable site-office quotation. Share the destination, desired layout, confirmed interpretation of “700 wide,” quantity, and delivery expectations when making an enquiry. This gives the supplier a clearer basis for preparing a drawing and scope for review.

Conclusion: What to Confirm Before Buying

A 700 Wide Expandable Site Office can be a practical option when a project needs a transportable workspace that opens into a larger configuration, but the model name alone is not enough to plan a purchase. Confirm the meaning of the width designation, review the closed and expanded dimensions, and match the interior and services to the intended use. Then check site access, ground preparation, setup responsibilities, delivery scope, and local requirements.

Your next step is to prepare a brief covering application, layout, site conditions, utilities, quantity, and destination, then request a dimensioned drawing and itemized quotation. Review those documents with your project, logistics, and compliance teams before approving production. For a project-specific discussion, contact Hongshun Guangju with your requirements and ask for the proposed configuration and supply scope in writing.
