I have a question! Why are the things half in half out in the structure?

Chloe Ward, it is because they won't allow me to adjust sizes in contests. So to make the room look the way I want from the inside, I have to have parts of some items stretch outside of the room. For instance, I wanted to use the wood pattern on the side of the chairs to create a pattern on the wall and the only way to create that was for most of the chair to be outside of the room.
