Redditor VaultoftheSix did something truly incredible for his combination 30th birthday and Halloween party - he and his friends turned his garage into a full-blown Fallout-style Vault: Vault 30.
This house was built during the Cold War. The half of it is built under the ground to protect its owners during the nuclear apocalypse. The house has an undeground lawn with a BBQ grill, pool, etc.
