ModBox Shipping Container Homes

The possibilities are endless for the configuration and design of your shipping container home: imagine them as life-size Lego blocks and you will start to see the vast possibilities. Easily add on to your container
home as your family grows. Single Family, multi-family, tiny homes, guest houses, cottages, or saunas.
When it comes to construction methods and building materials there are few alternatives that are as durable, portable and sustainable.

Modular construction isn’t a new idea, but often when people think modular they think temporary, and temporary often means junk. But with shipping containers, modular means flexibility without jeopardizing quality. Pre-manufactured modular construction is a more versatile and predictable way to build.
