Terraria Compact Housing - Right to left, the slope will. Houses in terraria require complete walls and a ceiling. They need at least 1 solid block (not platform blocks) to stand on. The block cannot be next to the wall. It's a really simple and easy design to build. Apparently they don't count as obstructing npc housing space while torches still do. For those of you who are like me and are obsessed with efficiency, here are the most efficient crafting. It's quite simple, it has to have a minimum total area within your house of 30 blocks and a maximum of 600 (verified on pc version as of 1. 2. 4). Meaning the smallest suitable npc.
