Tried to make this thing using only materials available at the start of the game: wood, stone, dirt, sand, iron and gel. Its got a full crafting setup, space for a hellivator and storage room. It also deliberately doesn't count as housing so NPCs won't barge in but I can still set my spawn.
Damn! Looks super nice. You’ve got a great eye! Really digging the well-style hellivator, very creative
