A little pre-hardmode modern base, i want some opinions, maybe what to add here when i will be in hardmode? *P.S ( other npc have their own homes=) ).

A bigger crafting room on each side of the npc houses, and if you need more npcs, dig down, and then at the bottom, once you have every npc, you dig a hellevator at the bottom

5 wide platforms to get up and down, thank me later
