Recently I have been attempting a few room redesigns on Happy Home Designer where I make a complete house for the villager with all the living necessities (bedroom, kitchen, bathroom) in just a one room layout. I was watching some episodes of Tiny House Nation on Netflix in the background while working on my New Leaf town, which is what gave me the idea.
Henry's original request was a "contemplative train trip" so I decided to keep his house long like a train car (along with the handle grips) which I thought was fitting because a lot of actual tiny houses are mobile homes or fit into old buses and trains.
