1. Base 30ft Expandable Container House Prices
| Product | Dimensions | Included Windows | EXW Price |
|---|---|---|---|
| 30ft Expandable Container House | 9000 × 6300 × 2480 mm | 8 | USD 7,670.00 |
| 30ft Single-Side Expandable Container House | 9000 × 6300 × 2480 mm | 4 | USD 7,094.29 |
Both prices refer to the basic white-frame configuration.
The frame colour can be customised, including for a single unit.
The standard 30ft expandable container house costs only USD 575.71 more than the single-side model.
Therefore, the single-side model should normally be selected because of site width or layout requirements, not simply to save money.
If the site can accommodate the standard model, the additional internal space usually provides better value.
How Large Is a 30ft Expandable Container House?
The standard model measures:
9000 × 6300 × 2480 mm
After expansion, it provides approximately:
56.7 square metres of floor area
This is usually enough for:
- Two bedrooms
- One bathroom
- A kitchen
- A living and dining area
A compact three-bedroom layout is possible, but the bedrooms and shared living area will be smaller.
20ft vs 30ft vs 40ft Expandable Container House
| Model | Expanded Floor Area | Base EXW Price | Price per m² |
|---|---|---|---|
| 20ft Expandable Container House | 37.17 m² | USD 5,348.57 | USD 143.89 |
| 30ft Expandable Container House | 56.70 m² | USD 7,670.00 | USD 135.27 |
| 40ft Expandable Container House | 74.34 m² | USD 9,794.29 | USD 131.75 |
Compared with a 20ft model, the 30ft house provides approximately 52.5% more floor area, while the base price is approximately 43.4% higher.
Its price per square metre is therefore lower than the 20ft model.
The 40ft model remains slightly more cost-efficient per square metre, but not every project needs 74 square metres.
The 30ft model makes sense when:
- A 20ft house is too small
- A 40ft house is larger than necessary
- The site cannot accommodate a 40ft model
- A practical two-bedroom layout is required
- The buyer does not want to pay for unused space
Is a 30ft Model Efficient for Shipping?
A standard 20ft expandable container house normally loads two units into one 40HQ container.
A 30ft model normally loads one unit.
A 40ft model also normally loads one unit.
This means the 30ft model is not the most efficient choice if maximum floor area per shipping container is the only priority.
Its value comes from matching the required building size more closely.
2. Interior Layout and Bathroom Prices
| Upgrade | Specification | Unit | EXW Price |
|---|---|---|---|
| Standard Internal Partition | Includes one partition door | Room | USD 232.14 |
| Integrated Decorative Partition | Double-sided carbon crystal panels and one door | Room | USD 380.71 |
| Standard Bathroom Package | Standard sanitary, water supply and drainage configuration | Set | USD 1,002.86 |
| Premium Bathroom Package | Frameless glass shower door and upgraded decorative wall finish | Set | USD 1,290.71 |
| L-Shaped Kitchen Cabinet | Layout can be customised | Set | USD 520.00 |
| Bamboo-Wood Fibre Ceiling | Ceiling upgrade for both expandable sides | Set | USD 399.29 |
The standard bathroom includes:
- One aluminium entrance door
- One aluminium sliding shower door
- One toilet
- One vanity and basin
- One handheld shower
- One floor drain
- Water supply and drainage pipes
- One marble shower base
The premium bathroom includes a custom frameless glass shower door and upgraded decorative wall finishing.
The price difference between the two bathroom packages is:
USD 287.85
The premium package primarily enhances the bathroom’s appearance and décor, and upgrades amenities such as the toilet, vanity, and showerhead.
How Many Partitions Does a 30ft House Need?
A typical two-bedroom layout may require two bedroom partitions plus the bathroom enclosure.
The exact number depends on the layout.
A standard partition is the lower-cost option.
An integrated decorative partition uses double-sided carbon crystal panels and requires less additional interior finishing after delivery.
3. Window Prices
A typical two-bedroom layout may require two bedroom partitions plus the bathroom enclosure.
The exact number depends on the layout.
A standard partition is the lower-cost option.
An integrated decorative partition uses double-sided carbon crystal panels and requires less additional interior finishing after delivery.
| Window Type | Size | Unit | EXW Price |
|---|---|---|---|
| Aluminium Window | 930 × 1130 mm | Piece | USD 52.00 |
| Thermal-Break Aluminium Window | 930 × 1130 mm | Piece | USD 89.14 |
| Aluminium Window for Integrated Wall Panel | 980 × 1130 mm | Piece | USD 61.29 |
| Thermal-Break Window for Integrated Wall Panel | 980 × 1130 mm | Piece | USD 102.14 |
The standard 30ft expandable container house already includes eight aluminium windows.
The single-side model includes four.
The prices in the table apply to additional windows or separately quoted window configurations.
For included windows that are changed to thermal-break aluminium, the final upgrade amount should be clearly listed in the quotation.
For long-term residential use, thermal-break aluminium windows are usually a valuable upgrade.
The sealing gasket should be EPDM rather than PVC. PVC gaskets are more likely to harden, shrink and lose elasticity over time.
4. Exterior and Structural Upgrade Prices
| Upgrade | Specification | EXW Price |
|---|---|---|
| Exterior Decorative Cladding | Metal decorative panels, including installation | USD 668.57 |
| Exterior Wall Panel Upgrade | 75 mm integrated wall panels | USD 566.43 |
| Expansion Assistance System | Four hydraulic rods and two manual gears | USD 204.29 |
| Sloped Terrace Roof | 6300 × 2000 mm | USD 538.57 |
| Raised Container Base | Raised structural base | USD 1,105.00 |
| Terrace | 6300 × 2000 mm with WPC decking | USD 910.00 |
| Full Additional Roof | EPS sandwich-panel roof | USD 1,021.43 |
Exterior metal decorative panels improve the appearance and add another protective layer outside the original wall panels.
The 75 mm integrated wall panel is a wall-system upgrade, not an additional decorative layer.
The expansion assistance system includes four hydraulic rods and two manual gears. It makes opening the house easier, but correct lifting and installation procedures are still required.
The raised base increases the height of the house above the ground. It does not replace a properly prepared foundation.
How Much Does a Roof and Terrace Cost?
A complete EPS roof and terrace system costs:
- Full additional EPS roof: USD 1,021.43
- Terrace with WPC decking: USD 910.00
Combined EXW price: USD 1,931.43
This is one of the most valuable upgrades for a 30ft expandable container house.
The additional roof provides:
- Better rain protection
- Lower long-term leakage risk
- Better thermal insulation
- Less rain noise
- Lower condensation risk
- Protection for the original folding roof
The terrace creates additional outdoor space.
The disadvantages are the extra cost, more installation work and reduced loading efficiency when several houses are shipped together.

Is a 30ft Expandable House Better Than a 20ft or 40ft Model?
Choose a 30ft model instead of a 20ft model when:
- Two proper bedrooms are required
- The 20ft living area is too small
- Better separation between rooms is needed
- A complete kitchen and bathroom are required
Choose a 40ft model instead when:
- Three bedrooms are required
- Two bathrooms are required
- A larger living room is important
- Maximum floor area per 40HQ is the priority
- The site has enough length
The 30ft model is not automatically the best compromise.
It is the correct option when approximately 56.7 square metres matches the actual project requirement.
