The 'Doomsday shelter' being built below Kansas prairie where millionaires will be able to sit out the Apocalypse in style

* Four buyers have already invested in condos below the ground
* Fears range from pandemics, terrorism and solar flares
* Indoor farm to provide fish and veg for 70 people for as long as necessary

When you buy a house, you end up feeling like you will be paying it off until the world ends.
Well, how about one of these luxurious condos, which come with all the mod-cons, as well as a pool, a movie theater and a library - oh, and a guarantee that it will survive Doomsday if and when that fateful day comes.

For these luxury flats, deep below the Kansas prairie in the shaft of an abandoned missile silo, are meant to withstand everything from economic collapse and solar flares to terrorist attacks and pandemics.

Naturally, there will be no one around to phone if the guarantee fails - but at that point, the insurance will probably be the least of your worries.

So far, four buyers have thrown down a total of about $7million (£4.4m) for havens to flee to when disaster happens or the end is nigh. And developer Larry Hall has options to retro-fit three more Cold War-era silos when this one fills up.

Hall said: 'They worry about events ranging from solar flares, to economic collapse, to pandemics to terrorism to food shortages.'

These 'doomsday preppers', as they are called, want a safe place and he will be there with them because Hall, 55, bought one of the condos for himself. He says his fear is that sun flares could wipe out the power grid and cause chaos.

He and his wife and son live in Denver and will use their condo mostly as a vacation home, he says, but if the grid goes, they will be ready.

Hall isn't the first person to buy an abandoned nuclear missile silo and transform at least part of it into a shelter.

Built to withstand an atomic blast, even the most paranoid can find comfort inside concrete walls that are nine feet thick and stretch 174 feet (53 meters) underground.
