A Custom 700 Expandable Container House is a transportable building whose usable space increases when its side wings are opened at the destination. The term “700” may refer to a model name or size category, so buyers should not assume it guarantees a particular floor area or set of dimensions. Before requesting a quote, confirm the unit’s packed and deployed measurements, proposed layout, site requirements, and included equipment in a supplier drawing. This guide explains how to compare sizes, plan layouts, specify custom options, and prepare a useful inquiry for Hongshun Guangju.

This guide is intended for developers, contractors, project buyers, distributors, and organizations sourcing expandable accommodation or site facilities. It is particularly useful when a standard unit does not match the planned use, site footprint, or interior arrangement. Buyers at the concept stage can use it to organize requirements before requesting technical proposals. Buyers comparing quotations can use the selection framework to identify differences that are easy to miss.
An expandable container house is transported in a more compact configuration and opened at the installation site to create additional interior space. Depending on the design, expansion may involve folding side sections, structural connections, and finishing details that must be set up according to the supplier’s instructions. The “700” designation alone does not establish the unit’s deployed footprint, room count, or included systems. Ask the manufacturer to identify the exact model and show its dimensions in both transport and use configurations.
Configurations can differ in structural framing, wall and roof panels, floor construction, doors, windows, and interior finish. Buyers may also be able to specify partitions, lighting, electrical provisions, plumbing, air conditioning preparation, or sanitary facilities, subject to the model and project requirements. These features should be treated as quotation items rather than assumed inclusions. Request a written specification that separates standard supply from optional or project-specific work.
For an initial comparison, ask each supplier to state the same core measurements: packed length, packed width, packed height, deployed length, deployed width, and usable floor area. Also confirm the number and position of doors and windows, the clear height, and any transport or installation constraints. A dimensioned drawing is more useful than a product name or a single headline measurement. If the proposed design changes, request a revised drawing before approving production.
For accommodation, start with the number of occupants and the activities the unit must support, such as sleeping, cooking, washing, or shared dining. Decide whether the project needs separate sleeping rooms, a combined living area, or dedicated sanitary space. A layout that fits the requested room count on paper may still be unsuitable if door swings, furniture, or circulation routes are overlooked. Ask for furniture positions and clear passage areas to be shown on the floor plan.
For an office or project facility, prioritize workstations, meeting space, storage, and the location of power and data provisions. For a site cabin, consider access routes, the expected frequency of relocation, and how the unit will connect to site services. Retail, reception, or visitor-facing uses may require different window placement, finishes, and entry arrangements. Share the intended use with the supplier so the proposed layout reflects actual operations rather than a generic room plan.
Record the available site footprint, access route, ground conditions, local weather considerations, and any applicable building or safety requirements. Clarify whether the building will be used seasonally, for a defined project period, or as a longer-term facility. Identify who is responsible for foundations, lifting, installation, utility connections, and local approvals. These responsibilities can affect both the design and the total delivered project scope.

Use deployed dimensions to check whether the open unit fits the site, and packed dimensions to assess transport and access. As a purely illustrative calculation—not a specification for a 700 model—a deployed footprint of 7.0 m by 6.0 m would equal 42 m² before accounting for wall thickness or unusable areas. Ask the supplier to state the actual usable floor area and explain how it is calculated. Confirm that the open configuration leaves sufficient clearance around the structure for access and operation.
Mark the intended location of partitions, doors, windows, furniture, lighting, and electrical outlets on a plan. List plumbing fixtures and connection points if the project requires water or drainage, and specify any equipment that affects power demand. Give suppliers the same scope so their quotations can be compared fairly. If you are still deciding between layouts, request alternatives with clearly identified differences rather than combining assumptions from separate proposals.
Request a clear response for each requested modification: available, unavailable, or subject to technical review. Confirm whether changes affect the structure, transport configuration, installation sequence, or maintenance requirements. Ask which items are included in the quoted supply and which must be sourced or installed locally. Written confirmation helps prevent misunderstandings between the concept drawing, quotation, and final production documents.
The price of a custom unit depends on the confirmed dimensions, layout, materials, equipment, finish level, and delivery scope. Freight, unloading, installation, utility work, taxes, and local compliance costs may be quoted separately, so compare the complete project scope rather than only the unit price. Minimum order quantities and production lead times are supplier- and configuration-dependent. Request current terms for your exact model, order quantity, destination, and required delivery window instead of relying on general estimates.
To help a supplier prepare a relevant quotation, include the intended application, target quantity, destination country or port, preferred layout, required options, and expected schedule. Attach site dimensions or a preliminary drawing if available. Identify which requirements are mandatory and which can be adjusted to meet budget or transport constraints. A complete inquiry makes it easier to identify technical questions early.
Evaluate responses for clarity and consistency as well as price. A detailed proposal should make it possible to see what is included, what remains undecided, and what the buyer must arrange locally. Ask for revisions when drawings and quotation descriptions do not match. Do not treat a feature as confirmed until it appears in the agreed specification.
Hongshun Guangju supplies customizable expandable container house solutions for B2B projects and can discuss configuration requirements with buyers. The suitability of a specific layout or option depends on the requested model and project details, so buyers should provide their use case, dimensions, and required features for review. Our team can use that information to clarify available configurations and prepare a scope for quotation. Confirm all technical details, commercial terms, and delivery responsibilities in the written proposal before placing an order.
A Custom 700 Expandable Container House should be selected by verified dimensions and project fit, not by the model name alone. First define the site, occupancy, layout, and service needs; then compare deployed and packed measurements, inclusions, customization limits, and supplier responsibilities. The illustrative 7.0 m by 6.0 m example in this guide is only a planning calculation and should not be treated as a standard 700 specification. Send Hongshun Guangju your intended application, target quantity, destination, layout priorities, and schedule to begin a project-specific discussion and quotation.
