I try to find a good mix, but I'm definitely more for efficiency. It's hard to not just make a box with everything nice and close by.

My most recent base is a bit prettier to look at. I've got a main hall with long tables overflowing with food and drink, hearths lighting the center, banners along the ceiling, walls lined with armor stands and monster trophies (but it's all secretly for that fat comfort levels). Then I've got several smaller structures for a smithy (smelter/kiln/forge), another as a general work area (workbench stuff), and another structure for my kitchen.

It all looks pretty good, but also... they're a bunch of boxes.
