Im actually going the other way. I did a giant castle and got bored trying to find things to do in it to make it cooler. After a treasure room, trophy room, crafting rooms, kitchen, bedroom, portal room, storage room, farm, bathroom, hot tub/sauna, and still having about half of it left to fill I realized it was really just too big for me.

My new character is going very small. I have a 2 room, 5x4 big floor tiles home and am trying stuff everything into it. Exceptions are the obvious outdoor kiln/forges/farm/windmill type stuff and my fire pit is actually one floor tile outside the home to give it that side-mounted chimney look and design. I think the hot tub is going to give me troubles... everything else, I think will be ok
