Quick Answer
A double-wing expandable container house is commonly understood as a factory-built unit with a central transport section and two side sections that open at the destination. The term is also used alongside dual-wing, bi-fold, butterfly and expandable house. These names do not create a universal specification. Before comparing prices, buyers should verify the exact model, expanded and folded dimensions, room plan, net and packed weights, operating details, utility scope, loose parts and destination responsibilities.
Current search results show strong use of double-wing terminology around 20ft and 40ft products, family layouts, dealer supply and fast-deployment housing. The useful search answer is therefore not a generic claim that every unit doubles in size. It is a checklist that helps the buyer connect the commercial label to a dimensioned Xutuo model and an order-specific evidence pack.
What Xutuo House Publishes — and What Still Needs Confirmation
Xutuo House lists expandable houses as a main product category and publishes 10ft, 15ft, 20ft, 30ft and 40ft expanded-size references on its XT-EH007 customization page. Its product directory identifies 20ft XT-EH003, 30ft XT-EH002 and 40ft XT-EH001 models. Xutuo does not publish a single universal double-wing specification, so this article uses the market term for search relevance while directing every technical claim to the selected model and approved documents.
| Evidence rule: manufacturer-published information is attributed to Xutuo House. Order-specific dimensions, materials, performance, certificates, loading, timing and commercial terms must be confirmed in current approved documents before publication or purchase. |
Why This Topic Matters in Current Search
This topic was selected after reviewing current Google result patterns and Xutuo’s present product fit. Search-result language is used only to identify buyer intent. Competitor dimensions, prices, ratings, certifications and cases are not reused as Xutuo facts.
Key Buyer Takeaways
The reliable decision path is consistent across product and application searches: identify the exact Xutuo model or custom request, provide the destination and intended use, approve a dimensioned layout, separate standard and optional scope, request final package and site-interface data, and define the evidence and inspection records needed before production. Website descriptions help form the inquiry, while the signed quotation, approved drawings, schedules and project-specific reviews control the order. Any missing value should remain marked for confirmation rather than being estimated from a competitor page or an unrelated model.
1. Translate the Product Name into Measurable Data
Ask the supplier to identify the model code and issue dimensioned folded and expanded drawings. Confirm external dimensions, finished internal dimensions, wall build-ups, clear ceiling height, door and window openings, floor transitions and every part that moves or connects during deployment. A nominal 20ft or 40ft label is not a substitute for millimetre dimensions.
Separate net product weight from package gross weight and lifting weight. Freight planning needs package count, dimensions, gross weights and loading arrangement; crane planning needs the approved lifted condition, lifting points and rigging inputs. Do not transfer a loading quantity from another supplier or configuration.
- Model and drawing revision
- Expanded and folded dimensions
- Finished room dimensions
- Net versus packed data
- Deployment and lifting information
2. Approve the Layout and Expansion Interfaces
Place real beds, cabinets, kitchen equipment, bathroom fixtures and circulation on the plan. Check door swings and the relationship between the central section and both wings. Identify any floor, wall or roof joints that require site connection, finishing, sealing or inspection after opening.
The room count should follow usable dimensions and intended occupancy rather than a marketing image. One-bedroom, two-bedroom and multi-bedroom plans can place different demands on ventilation, electrical loads, hot water, drainage, storage and privacy. Freeze the plan before the related services are released for production.
- Furniture and circulation plan
- Wing and centre-zone interfaces
- Kitchen and bathroom positions
- Service routes and connection points
- Site finishing and sealing scope
3. Compare the Complete Delivery Chain
Request a scope matrix showing factory-installed work, loose shipped parts, locally supplied items and exclusions. Confirm the foundation or support interface, crane and access, installer responsibilities, utility connection, testing, local review and handover. The fastest factory assembly claim does not define the full site programme.
For repeat or dealer orders, approve a reference configuration and control later batches by model code and revision. Record substitutions, inspection results, package identities and installation feedback. Repeatability matters more than a long list of unstructured options.
- Inclusion and exclusion matrix
- Foundation and access plan
- Factory and site inspection points
- Batch traceability
- Handover and change records
RFQ and Evidence Pack
For a comparable quotation, issue the same project brief to every supplier. State the intended country and site, use, quantity, selected model or required space, layout, options, destination design inputs, requested evidence, trade term and delivery point. Ask the supplier to list assumptions and exclusions instead of filling missing information silently. A quote should identify its validity date and the revision of every attached drawing or schedule.
Keep commercial and technical acceptance connected. The lowest price may represent a different wall, roof, finish, wet-area, electrical, furniture, packing or documentation scope. Normalize those differences before selection. If a required fact is unavailable, mark it as pending confirmation; do not replace it with a competitor value, an example from the client workbook or a generic industry number.
- Country, site and intended use
- Required size and room plan
- Model-specific expanded and folded drawings
- Net weight, package data and lifting inputs
- Kitchen, bathroom and electrical schedules
- Foundation, crane and installation responsibilities
- Inspection and document deliverables
- Quotation with assumptions and exclusions
Quotation Comparison and Revision Control
After selection, create a document register that identifies the current floor plan, elevations, sections, material and finish schedules, kitchen and bathroom scope, electrical and plumbing information, package data, installation instructions and evidence list. The buyer and supplier should use a written change process. Each change needs a description, reason, technical and commercial effect, affected units and approved revision.
Treat website text as the start of the inquiry, not the final contract. Product titles, images and general service statements can help buyers choose questions, but the signed quotation, approved drawings, schedules and agreed inspection records should control the order. This distinction is especially important when a model is customized or when destination professionals request additional information.
Recommended Buying and Acceptance Sequence
- Freeze the project brief, destination inputs, model and approval responsibilities.
- Approve the layout, inclusions, materials or systems relevant to the article topic.
- Agree inspection hold points, document deliverables and the change procedure.
- Reconcile the completed unit, loose items, package data and loading records before shipment.
- Inspect on arrival, complete site work and commission through responsible qualified parties before use.
Frequently Asked Questions
Is double-wing the same as expandable container house?
It is commonly used for a two-sided expandable product form, but terminology varies. Confirm the actual drawings and mechanism for the quoted model.
Does every double-wing house expand to twice its transport area?
Do not assume a fixed ratio. Use the selected model’s exact folded and expanded dimensions.
Which Xutuo sizes can be discussed?
Xutuo’s current customization page publishes expanded-size references for 10ft, 15ft, 20ft, 30ft and 40ft families. Availability and final configuration require quotation confirmation.
Can the house be repeatedly folded and moved?
Request the model-specific disconnection, inspection, folding, lifting, transport and recommissioning procedure before planning repeated relocation.
Request an Order-Specific Response from Xutuo House
Send Xutuo House the destination, intended use, quantity, target layout, required options, site constraints, delivery point and evidence list. Ask the sales and technical teams to reply against the same numbered RFQ items. This produces a more reliable answer than requesting only a catalogue price or relying on a product image.
