40′ One Bedroom One Bathroom
Are you looking for a container home that ticks all the boxes of superior insulation, proper ventilation, premium finish and practical design and is ‘off-grid’ ready if you prefer?
Look no further than our Mark VI, beautifully designed with the cutting-edge VenSulation system that ensures a healthy and comfortable home, whilst eliminating condensation and mould.
The walls and ceiling are insulated with 70mm PUR panels (Premium) + 32mm PUR infills and the underfloor with optional Polyester. We only use thermally-broken double glazing with high end design finishes. The practical layout features a double bedroom, a full kitchen with breakfast bar, a spacious bathroom with laundry, a lounge area and a utility compartment for tools, hot water and ar-con systems.
Something Simple
What starts as a simple steel container can evolve into a meaningful, expansive home. By combining units, we create layered, light-filled spaces designed for genuine liveability.
Our four-container family residence in Victoria, built with our partners Sonic Steel, proves that “container homes” can be warm and intentional. Now, we’re bringing this approach to Western Australia with projects that prioritise performance, comfort, and longevity.
Ultimately, it’s not about the steel; it’s about improving how people live. Explore what happens when a container home becomes a Little Castle.
INSULATION
At Little Castles, we’ve set a new standard for shipping container insulation. Tackling the issues of thermal efficiency and condensation build-up head on, our priority is to address the challenges faced by many shipping container home enthusiasts.
Our comprehensive approach doesn’t just stop at insulating the metal walls, but also covers the underfloor insulation (which can contribute up to 20% thermal loss), as well as the highly efficient windows and doors, making your container home comfortable regardless of the season.
VENTILATION
Little Castle’s state-of-the-art ventilation systems are designed to keep your shipping container home fresh, comfortable and free from condensation and mould.
The integration of Heat Recovery Ventilation (HRV) into our designs sets us apart, ensuring that fresh, filtered air continuously circulates throughout your container home, providing a healthy living environment.
Along with an efficient HRV system, we also focus on the airtightness and air quality of your shipping container home by means of vent dampers and toilet’s odour extraction unit.
