The entrance to the condo has two doors that are 16,000 pounds each.
Here's a floor plan. The condo goes 174 feet underground.
And this is what a unit looks like. Full- and half-floor units are available. Full-floor units have 1,820 square feet of space and a maximum occupancy of 10 people. Half-floor units are 900 square feet and have a maximum occupants of 5 people. All of the fully furnished units have a full kitchen with stainless steel appliances and Kohler fixtures, a washer and dryer, a 50-inch television, and a five-year food reserve per person.
Of course, there is 24-hour surveillance.
Part of the reason why the condos are so pricey are the amenities. If you're going to be stuck 174 feet underground when the apocalypse comes, you're going to want something to do. There's a community pool with an outdoor scene painted on the walls.
