In the past few years, we have covered plenty of cool shipping container houses here. The South Beach Reflection Mobile House is also worth a look. It is a shipping container house measuring 40ft long. It has a reflective body, so it will turn heads.
These houses have a solid steel frame with insulation. They are solar powered and fully electric. These tiny comes come with a built-in HVAC system to keep you comfortable. You can even fit a fireplace inside.
