Shipping container homes are one of the most versatile and space-efficient housing options available today. Whether you’re building a compact weekend retreat or a multi-module residence, container homes offer a wide range of size and layout possibilities. But how big are they really?
In this blog, we break down the standard sizes of shipping container homes, popular layout options, and how Express Portables helps customers make the most of their space.

Beyond the Box: Custom Layout Possibilities
Container homes can be as small or large as your space and budget allow. Multiple containers can be joined side-by-side to create larger layouts.
Popular Configurations:
- Single 20ft or 40ft unit: Ideal for studios or guest accommodation
- Two 20ft units side-by-side: Creates a wider floor plan with kitchen/living area
- Two 40ft units with deck or breezeway: Great for family-sized layouts
Customisation is key. At Express Portables, you can choose from a variety of floor plans or request a layout tailored to your land and lifestyle.
Designing for Comfort in Compact Spaces
Maximising usability in a container home means smart design choices:
- Use sliding doors and windows to save space
- Install multi-purpose furniture like sofa beds and folding tables
- Incorporate built-in storage solutions under beds or stairs
- Consider open-plan layouts to make smaller interiors feel more spacious
These thoughtful design elements allow even the smallest container home to feel functional and inviting.
Expandable Container Homes: Transform Your Space On-Site
Expandable homes, like those offered by Express Portables, begin compact and expand on-site to increase liveable area without requiring transport of larger units.
Our Expander Homes can expand up to 6m wide when deployed, offering significantly more interior space than a fixed-size container—perfect for families or long-term use.
These hybrid designs offer the best of both worlds: easy transport and spacious interiors.
Is a Container Home the Right Size for You?
The answer comes down to your lifestyle and space requirements. Whether you’re after a minimalist one-person retreat or a spacious multi-container residence, there’s a container home size that can meet your needs.
