How Many Container Houses Fit in a 40HQ Container?

Last updated: July 2026

Quick Answer

The number of container houses that fit in a 40HQ shipping container depends on the house type, folding structure, packing method, and included accessories.

Under the standard export packing configuration used by Xinheng Integrated Housing Technology (Suzhou) Co., Ltd., one 40HQ container can typically carry:

A 20GP container can also carry approximately 8 standard detachable container houses.

In this article, “fit” refers to houses packed in their transport condition—not fully assembled buildings placed inside the shipping container.

Container House Loading Capacity Comparison

1. Standard Detachable Container House

The standard detachable container house has an assembled external size of:

3000 × 5950 × 2800 mm

Before transportation, the steel frame, wall panels, roof components, floor system, doors, windows, and accessories are disassembled and packed into compact bundles.

Typical loading capacity:

• 20GP: 8 sets
• 40HQ: 18 sets

This is the most freight-efficient option among the three main container house systems.

Because 18 complete house sets can be transported in one 40HQ, detachable container houses are particularly suitable for:

• Large construction camps
• Worker accommodation projects
• Temporary offices
• Mining camps
• Oil and gas projects
• Emergency accommodation
• Schools and medical facilities
• Large distributor orders

For projects requiring dozens or hundreds of rooms, the higher loading quantity can significantly reduce the average ocean freight cost per unit.

Why Can a 40HQ Carry 18 Detachable Houses?

A detachable container house is shipped in knocked-down form. Instead of transporting the complete three-dimensional building, the factory stacks the main structural components into compact packages.

This packaging method reduces unused space inside the shipping container and allows more building units to be shipped in one load.

The main advantage is clear:

More houses per shipping container means a lower average transportation cost per house.

However, detachable houses require more on-site assembly work than foldable or expandable models.

2. Foldable Container House

Foldable container houses are delivered with most structural components already connected. After unloading, the house can be unfolded and installed much faster than a fully detachable unit.

There are two common designs:

• X-type foldable container house
• Z-type foldable container house

X-Type Foldable Container House

The nominal folded size of an X-type unit is approximately:

5800 × 2500 × 340 mm

One 40HQ container can typically carry:

12 X-type foldable container houses

The X-type model offers a good balance between shipping efficiency and installation speed. Its folded height is only about 340 mm, allowing several units to be stacked for transportation.

It is suitable for:

• Temporary worker accommodation
• Construction site offices
• Disaster-relief housing
• Temporary classrooms
• Project camps
• Rapid-deployment buildings

Because product dimensions and export packaging methods may differ, the final packed width and loading arrangement should be confirmed before shipment.

Z-Type Foldable Container House

One 40HQ can typically carry:

10 Z-type foldable container houses

The Z-type model can only be transported using a 40HQ under the standard loading plan.

Compared with the X-type model, its loading quantity is slightly lower, but the Z-type structure is designed for fast installation and repeated use. It can be folded, transported, reopened, and relocated for multiple projects.

This makes it especially suitable for contractors and rental companies that regularly move temporary buildings between construction sites.

Common applications include:

• Reusable construction camps
• Mobile offices
• Temporary dormitories
• Equipment rooms
• Project management centers
• Rental housing fleets

3. Expandable Container House

Expandable container houses are available in several sizes:

• 10ft
• 20ft
• 30ft
• 40ft

Because expandable houses include more pre-installed interior components and a larger folded structure, they occupy more shipping space than detachable or foldable units.

They can only be transported in a 40HQ under the standard export plan.

Expandable House Loading Combinations

One 40HQ container can carry any of the following standard combinations:

• 4 × 10ft expandable houses
• 2 × 20ft expandable houses
• 1 × 10ft house plus 1 × 30ft house
• 1 × 40ft expandable house

Expandable container houses provide less loading quantity per shipping container, but they offer a higher level of factory completion.

Depending on the project specification, the factory can pre-install:

• Interior wall finishes
• Flooring
• Electrical wiring
• Lighting
• Plumbing
• Bathroom fixtures
• Kitchen cabinets
• Doors and windows
• Built-in furniture
• Air-conditioning preparation

After arrival, the building can normally be expanded and connected on site with much less construction work.

Expandable houses are commonly used for:

• Private residences
• Holiday homes
• High-end hotels
• Resorts
• Airbnb accommodation
• Garden houses
• Guest houses
• Showrooms
• Luxury campsite accommodation

Which Container House Has the Lowest Shipping Cost?

For large-volume projects, the standard detachable container house usually provides the lowest transportation cost per unit.

One 40HQ can carry 18 detachable units, compared with:

• 12 X-type foldable units
• 10 Z-type foldable units
• 4 units of 10ft expandable houses
• 2 units of 20ft expandable houses
• 1 unit of a 40ft expandable house

However, shipping capacity should not be the only consideration.

The best choice depends on the total project quantity, local labor cost, installation schedule, intended use, and required interior finish.

Example: Shipping 180 Construction-Site Houses

Suppose a contractor needs 180 standard accommodation units.

Using detachable container houses:

180 ÷ 18 = 10 × 40HQ containers

Using X-type foldable container houses:

180 ÷ 12 = 15 × 40HQ containers

Using Z-type foldable container houses:

180 ÷ 10 = 18 × 40HQ containers

In this example, choosing detachable container houses could reduce the number of shipping containers required, helping control ocean freight, port handling, customs clearance, and inland transportation costs.

The foldable models may still be preferable when faster installation or repeated relocation is more important than maximum loading quantity.

What Can Change the Actual Loading Quantity?

The figures in this guide are based on standard product specifications and standard export packaging. The final quantity may change depending on:

• Wall-panel thickness
• EPS, rock wool, PU or PIR insulation
• Door and window quantity
• Bathroom or kitchen configuration
• Electrical and plumbing packages
• Staircases and corridors
• Exterior cladding
• Furniture and sanitary equipment
• Additional roof systems
• Packaging requirements
• Destination-country regulations
• Shipping-line container specifications

For customized projects, the manufacturer should prepare a final loading plan before confirming the shipping quotation.

The loading plan should show:

1. Quantity of houses per container
2. Package dimensions
3. Package weight
4. Accessory arrangement
5. Container sequence
6. Unloading requirements
7. Crane or forklift requirements
