The Catastrophe-Resistant Individual Bunker is a re-creation of the very first player home I ever built for myself in Fallout 3, and it's what I've been using ever since. It's pretty modest in terms of size and complexity, but it packs all the quality-of-life features I want for my playthroughs.
The entrance is disguised as a manhole cover, located at the Red Rocket gas station in Springvale. The key can be found on a corpse lying in a puddle just outside the entrance to Vault 101.
