15. 170 Sq. Ft. Rustic Bike House

Sarah and Tabatha love their life on the farm and want to simplify even more by going tiny. They've asked John and Zack to come help build them a rustic tiny house that can withstand all the dirt and grit of the farm life and keep them warm in the harsh Wisconsin winters. The only challenge is, Zack will have to figure out all that and find a place for a few prized bikes as well.
