At first when I made my sketch of my tiny house, I made it a single story house with a living, kitchen, bedroom, and bathroom. I made the rooms really small but with enough room to still be able to live normally in. i made it just a regular rectangular houe. I had the living room connected with the kitchen for easy access.

After I revised my sketch, I took in to consideration to make the house two stories. In order to not take up space, I used a ladder instead of stairs to get to the second floor. i kept the living room and kitchen on the bottom floor and put the bedroom and bathroom on the top.
