If you drive by the house at 3970 Spencer Street in Las Vegas, you might not think there's anything remarkable about it. But it's what you don't see that matters. And it can be yours for a mere $18 million! See, underneath the one-acre lot is a 15,000 square foot underground bunker. From the real estate listing:
Las Vegas Underground House! Its not just a house, its an subterranean 15,000sqft concrete & steel rectangular shaped doomsday bunker. The 5000 sqft House is built Inside this huge bunker & is finished with pool,spa,waterfall,trees,guest house,BBQ,fountain & 500 linear feet of floor to ceiling illuminated murals of landscapes of wide open spaces simulating day,dusk,dawn & night modes. All Furnishings & 1 year of caretaker & upkeep are included
It's got everything except windows, but to make up for that, there are nature scenes painted on the walls and colored lighting you can adjust for daytime and nighttime moods. It was built in 1978, with the original decor that will take you back to the Cold War era, overlaid with Las Vegas kitsch (think neon, pink, and astroturf).
Whether being underground in this home will keep you safe in the apocalypse would depend on the situation, though -it does use public utilities. See a gallery of pictures of this underground fantasyland at Old House Dreams. And more pictures here. -via Nag on the Lake
