Fallout 4: Vault-Tec Workshop (2016)

Vault-Tec Workshop is the fifth add-on, and third workshop add-on for Fallout 4. It triggers automatically once level 20 is reached and the player character is outside the Institute. Build a brighter future underground with the all-new Vault-Tec Workshop. Create a massive Vault and attract new Dwellers using pre-war industrial kits complete with retro-nostalgic furniture, lighting, and art. And like every good Overseer, run Vault-Tec approved experiments on your Dwellers to learn what makes an ideal citizen. Vault-Tec has given you the tools, the rest is up to you!
