I have a few hundred hours in terraria, but I've never really cared how my bases looked... Until I started playing again a few weeks ago. My normal world has each NPCs in living wood styled rooms with a painting each, but that was more because I was tired of digging. I'll be making a permanent expert (or master) world and plan to make themed and nice rooms for each NPC since digging and materials won't be an issue. My initial thoughts are a legit wizard tower for the wizard, a doomsday bunker for arms dealer and demo, living wood grove with active waterfall for dryad, fishing hut with pier for angler (going to actually do angler quests for the first time too), workshop for tinkerer steampunker cyborg and mechanic, and a cage surrounded by lava just above the underworld with the bare minimum metal furniture for the guide
