One challenge of using two 40-foot-long containers and one 20-foot-long unit in the main house was the different heights of the two types of containers. Rather than keeping the floor-level the same, Robertson chose to lift the kitchen container up a few feet to match the ceiling height of the other two modules and add a step between the kitchen and dinning room. "Every home has its challenges," Robertson says. "It's always like solving a Rubik's Cube."  Photo 14 of 22 in The Shipping Muse
