Compare 20ft and 40ft expandable homes by floor area, room planning, transport, unloading, site clearance and total project scope.
Compare project outcome, not only length
A 20ft model may suit compact one- or two-bedroom uses, while a 40ft model can separate more rooms and services. The correct choice depends on occupancy, site area, budget and transport route.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.
Use approved external and internal dimensions
The 20ft page uses an approximately 37 m² planning reference. The Huisheng T40-05 drawing shows one 40ft three-bedroom, two-bathroom arrangement at 11800 × 6140 mm; confirm current drawings before quotation.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.
Account for unloading and opening clearance
Larger units change truck access, crane capacity, turning space, support positions and the clear area required to unfold both wings.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.
Compare cost per usable function
Normalize bedrooms, bathrooms, kitchen, insulation, glazing, furniture, packing, freight, foundations, installation and local work instead of comparing shell prices.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.
Define the business case before choosing a model
Record whether the project is for residential sale, rental income, hospitality, workforce accommodation, commercial operation, emergency use or an internal facility. Add expected occupancy, operating period, unit quantity, target opening date and return-on-investment priorities.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.
Start with the site and destination constraints
Document the exact site, destination port, climate, wind and snow exposure, corrosion risk, access width, turning space, crane position, foundation conditions, utilities and local approval route. These factors can change the recommended product, structure and delivered cost.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.
Compare an equivalent technical specification
Ask suppliers to identify structural system, steel specification, wall and roof build-up, insulation, floor, doors, windows, electrical standard, plumbing, bathroom, kitchen, furniture, exterior package and installed equipment. A product name alone is not a comparable specification.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.
Compare floor plans and operational usability
Check external and internal dimensions, usable area, room count, circulation, furniture clearance, bathroom access, kitchen ventilation, storage, maintenance access and utility points. Approve a dimensioned drawing rather than relying on a staged rendering.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.
Build a complete landed and installed cost
Separate factory supply, optional fit-out, packaging, inland transport, export handling, ocean freight, destination charges, customs, inland delivery, unloading, crane, foundations, assembly, utility connections, permits, inspections and contingency.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.
Evaluate packing, transport and site installation
Confirm folded or packed dimensions, unit weight, container quantity, accessory packing, lifting points, assembly sequence, crew requirements, tools, weather protection, temporary supports and installation responsibilities.
- Record assumptions and exclusions.
- Ask for model-specific drawings or schedules.
- Confirm destination-side costs and responsibilities.

Frequently asked questions
Can I use an online price or loading number as a final budget?
Use it only as an initial reference. Final values require a current model, scope, quantity, packing plan, route and destination quote.
What should I send a supplier first?
Send country, port, site, use, quantity, preferred product or layout, climate and target schedule.
Who confirms local compliance?
The buyer should coordinate with qualified local professionals and authorities. The manufacturer can provide relevant product information and current documents for review.
