4x1 - Tiny House Nation

Sam and Ken just got married and are looking forward to building their first home together. They both want to be mindful of their footprint, and believe going tiny is the way of the future! They've asked John and Zack to come build them a home that's out of this world, but will their requests to shoot for the moon fall flat, or will John and Zack figure out a way to grab at the stars on this one-of-a-kind build?
