Dimensions of Assembly-Type Housing Containers

The dimensions of assembly-type housing containers vary widely, with common standard sizes primarily derived from international shipping container standards, while also including specialized specifications and custom sizes for residential, construction site, and other scenarios.

I. International Shipping Standard Sizes The standardized design of international shipping containers provides a foundational framework for assembly-type housing, with common specifications including:

• 20-foot Standard Container (20GP): External dimensions are 6.058m (length) × 2.438m (width) × 2.591m (height), with an internal usable space of approximately 5.898m × 2.352m × 2.393m and a volume of about 33 cubic meters. Such containers are often converted into single-container small residential units, with an indoor area of about 14 square meters and a typical layout of one bedroom, one living room, and one bathroom.
• 40-foot Standard Container (40GP): External dimensions are 12.192m × 2.438m × 2.591m, with an internal space of approximately 12.032m × 2.352m × 2.393m and a volume of about 67 cubic meters. When two containers are combined horizontally, the width can reach 4.876 meters, providing an indoor area of about 28 square meters that can be designed as a two-bedroom, one-living-room residence.
• 40-foot High Cube Container (40HC/HQ): External dimensions are 12.192m × 2.438m × 2.896m, with an increased internal height of 2.698 meters and a volume of about 76 cubic meters, suitable for scenarios requiring higher ceiling heights.

II. Common Specifications for Residential Scenarios To meet residential needs, assembly-type housing containers have evolved into various combination forms:

• Single-Container Residences: Based on the 20GP, these residences optimize internal layout for functional zoning, suitable for single individuals or small families.
• Multi-Container Combined Residences: By horizontally or vertically joining multiple containers, living space is expanded. For example, combining two 40GP containers can create a two-bedroom, one-living-room layout, while some custom projects even use three 40-foot containers to form a duplex structure measuring 11.8m × 6.75m × 2.8m, with a usable area of 80 square meters.
• Widened Custom Containers: To enhance living comfort, some containers can be widened to 2.8-3.2 meters, though compliance with oversized transportation regulations must be considered.

III. Common Sizes for Construction Sites and Temporary Uses Construction sites prioritize functionality and flexibility, with common specifications including:

• Standard Single Container: With a length of 6 meters, width of 3 meters, and height of 2.7-2.8 meters, it covers an area of about 18 square meters and is suitable for dormitories or temporary offices.
• Small Container Houses: Measuring 3m × 3m, they cover an area of about 9 square meters and are often used as guardhouses or tool warehouses.
• Large Container Houses: With a length of 7 meters and width of 3 meters, they can be extended by stacking on a second floor or adding corridors to meet office area needs.

IV. Other Custom Sizes For special needs, the market offers a variety of custom solutions:

• Foldable Container Houses: With a fixed length of 6000 millimeters and height of 2590 millimeters, the width can be adjusted as needed, facilitating transportation and storage.
• Non-Standard Sizes: According to project requirements, containers can be designed with lengths, widths, and heights that exceed conventional dimensions, though structural safety and transportation limitations must be comprehensively considered.
