Standard Shipping Container Sizes

Most container homes are built from one of two standard shipping container types. These serve as the foundation for everything from single-module studios to multi-container builds.

1. 20ft Container

• External dimensions: ~6.06m (L) × 2.44m (W) × 2.59m (H)
• Internal floor space: approx. 14m²
• Best for: studios, offices, granny flats, or guest pods

A 20ft unit is a great starting point if you’re exploring minimalist living or need a compact secondary dwelling. See our tiny houses guide for more compact design inspiration.

2. 40ft Container

• External dimensions: ~12.19m (L) × 2.44m (W) × 2.59m (H)
• Internal floor space: approx. 28m²
• Best for: 1–2 bedroom layouts or combined kitchen/living areas

The 40ft option doubles your space and allows for a more traditional home feel while maintaining portability. Compare costs in our Tiny Home Cost Guide.

Popular Container Home Layouts

The beauty of container homes lies in their modular design — multiple units can be joined, stacked, or expanded to create a custom layout.

• Single 20ft or 40ft unit: Ideal for solo living, Airbnb stays, or holiday cabins
• Two 20ft units side-by-side: Creates extra width for open-plan kitchen and living zones
• Two 40ft units with a breezeway or deck: Offers up to 56m² of space with great airflow and natural light
• Stacked configurations: Add a second storey for bedrooms or office space

Many builders also offer hybrid or expandable container homes, which fold out on-site to increase the liveable area without needing multiple containers. Learn more about modular homes in Australia.

 

 

 

Designing for Comfort in Compact Spaces

Container homes prove that good design can make small spaces feel big. Here are some design strategies from Australian builders who specialise in compact living:

• Choose sliding doors and large windows to open up tight areas
• Use multi-purpose furniture like sofa beds and foldable tables
• Incorporate built-in storage under stairs, benches, or beds
• Opt for open-plan layouts to create flow and maximise light

Even with a modest footprint, these choices make container homes feel functional, modern, and surprisingly spacious.

 

 

Expandable & Modular Options

Expandable container homes are gaining popularity across Australia. These designs travel compact but fold out on-site, often expanding up to 6m wide.

• Easier transport and installation
• Larger living areas without extra modules
• Flexibility to add decks, awnings, or solar systems later

They’re ideal for families, remote sites, or anyone who wants portability without sacrificing comfort. If you’re curious, see our article on moving modular and container homes in Australia.
