A useful prefab container house proposal begins with a clear request for quotation (RFQ). A product name and quantity are rarely enough. The intended use, destination, layout, local conditions, utilities, finishes and delivery responsibilities can all change the recommended configuration.
Providing this information at the beginning helps the supplier understand the project, identify questions early and prepare a proposal that is easier to compare. The following checklist explains what international buyers should include when requesting a quotation for a modular building project.
1. Explain how the building will be used
Start with the application rather than the product model. A unit intended for a temporary site office will have different requirements from worker accommodation, a classroom, a clinic support room, a retail space or a long-term residential project.
Useful information includes:
- The primary use of the building
- The expected number of occupants
- Whether the project is temporary, relocatable or intended for longer-term use
- The required rooms and shared facilities
- Expected daily operating conditions
This context helps determine whether a folding container house, expandable house, flat pack system or another modular configuration is appropriate.
2. Provide the project location and climate conditions
The destination affects material selection, thermal performance, corrosion protection, transport planning and the documents required for local review. State the destination country, region and, when available, the project city or site.
Buyers should also describe relevant environmental conditions, such as:
- Hot, cold, humid, coastal or high-rainfall conditions
- Expected temperature range
- Strong wind, snow or other site-specific loads that require professional review
- Exposure to salt air, dust or industrial environments
- Local energy-efficiency expectations
Local planning, structural, fire, electrical and plumbing requirements must be confirmed with qualified professionals in the destination market. Sharing available requirements early allows the manufacturer to identify which technical information can be supplied for that review.
3. Confirm quantity and project phasing
Specify the estimated number of units and whether delivery is expected in one shipment or several phases. For accommodation and camp projects, it is more helpful to provide the required capacity and functions than only a total unit count.
For example, a project may include sleeping rooms, offices, dining areas, sanitary modules, storage spaces and circulation zones. A phased schedule can also affect production planning, packaging, shipping and on-site installation support.
4. Share a preliminary layout
A hand sketch, marked-up floor plan or simple room schedule can prevent major misunderstandings. The first drawing does not need to be a finished architectural document, but it should show the intended arrangement.
Include the following where possible:
- Required room sizes and approximate overall dimensions
- Positions of doors, windows and internal partitions
- Bathroom, kitchen or utility areas
- Single-storey or multi-storey arrangement
- Corridors, stairs, terraces, canopies or connecting structures
- Accessibility requirements
The final layout should be reviewed together with structural requirements, transport limits and local regulations.
5. Define the expected supply scope
“Complete house” can mean different things to different buyers. A clear RFQ should distinguish between the factory supply and work that will be completed locally.
Clarify whether the requested scope includes:
- Internal wall, ceiling and floor finishes
- Electrical wiring, lighting and distribution components
- Plumbing lines and sanitary fixtures
- Kitchen cabinets or built-in furniture
- Air-conditioning provisions or equipment
- External stairs, walkways, railings or roof structures
- Installation guidance, supervision or local installation work
Also identify exclusions such as foundations, utility connections, lifting equipment, permits and local civil works. A written responsibility matrix is especially useful for larger projects.
6. State material and finish preferences
If the project has specific expectations for wall panels, insulation, doors, windows, flooring, interior finishes or exterior colours, list them in the RFQ. Reference images can help communicate the desired appearance, but technical requirements should still be written clearly.
When a specific brand or standard is requested, explain whether it is mandatory or whether an equivalent product may be proposed. This gives the supplier a clear basis for material selection without assuming requirements that have not been confirmed.
7. Include logistics and site-access information
The delivery plan should be considered before the configuration is finalised. Provide the preferred destination port or delivery city and describe any known transport restrictions.
Important questions include:
- Can standard shipping containers reach the destination?
- Are there road-width, height, weight or turning restrictions near the site?
- Will a crane, forklift or other lifting equipment be available?
- Is there enough space for unloading, assembly and temporary storage?
- Does the site require special packaging or component labelling?
These details help align the building system, packing method and installation sequence with actual site conditions.
8. Request clearly defined proposal documents
A professional proposal should make it easy to see what is included, what still needs confirmation and which assumptions were used. Depending on the project stage, buyers may request:
- Product configuration and preliminary dimensions
- Layout drawings or a room schedule
- Material and finish descriptions
- Included and excluded items
- Estimated production and packing information
- Delivery terms and quotation validity
- A list of technical points requiring further confirmation
For regulated projects, the quotation should not be treated as a substitute for local engineering approval. Final drawings and specifications should be reviewed by the appropriate professionals and authorities before construction or installation.
A practical RFQ summary
Before sending your inquiry, check that it contains these essentials:
- Application and occupancy
- Destination and climate
- Quantity and delivery phases
- Preliminary layout
- Required supply scope
- Materials and finishes
- Destination port and site access
- Target schedule
- Required proposal documents
Start with the project requirements
A clear RFQ does more than speed up quotation work. It creates a shared reference for product selection, technical discussion, pricing, documentation and delivery planning. Even when some information is still preliminary, identifying the open questions makes the next conversation more productive.
To discuss a prefab container house or modular building requirement, send Glorich House your intended application, estimated quantity, destination and preliminary layout through the website inquiry form. Our team can then review the available information and confirm the next details required for proposal preparation.
