The 12 Container House is a 4000 square foot home built in 2003 from 12 recycled shipping containers. It has a T-shaped design with two stories, floor to ceiling windows, and radiant floor heating. On the ground floor, the containers form the side walls and are open to reveal the kitchen and living area. Two steel staircases in the containers lead to the bedrooms on the second level. It is considered one of the premiere examples of shipping container architecture.
