For Sale: Super-Fortified And Booby-Trapped Estate
The safest house in America might be a sprawling 36,000-square-foot compound outside Atlanta. And it’s a bargain at $14.7 million.
Built to last 1,000 years and to withstand every type of attack, the eight-bedroom, 15-bathroom house cost $30 million to construct and was reduced from its original list price of $17.5 million.
The walls, built to withstand machine gunfire, are made of wood-frame construction reinforced with rebar and concrete with a strength of 5,000 pounds per square inch. Typical home construction uses concrete between 3,000 and 4,000 pounds per square inch.
Braided copper wires wrap around the wood framing to make the building safe from lightning strikes.
Maryland-based security expert Al Corbi, who has designed classified facilities for the U.S. government, came up with the safety design for the property. It includes a 15,000-square-foot, concrete-fortified bunker deep within the main building with multiple concealed entrances.
Interior and exterior doors throughout the house have three layers of Kevlar so they can withstand ballistic attacks, and a system of chromalloy pins that extend from the door’s edge in to the frame provide more than one locking mechanism for each entryway.
Should intruders make their way to the inner chambers of the house, they would still be vulnerable to a defense system called Man Traps. These discreetly placed nozzles can release stored gases that could incapacitate the person (if the homeowner has obtained noxious enough materials) or at least use harmless gases to obscure the visibility in the room so someone can’t escape.
An observation tower with remote window control oversees the property. It comes with a glass floor and secret spiral staircase entry so residents can see enemies coming and make a quick getaway.
The home has all the requirements for living off the grid – including water, electricity, heating, and a pantry big enough to hold a three-year supply of food.
Three artesian wells at a depth of more than 1,000 feet – at least one of which is connected to an aquifer – provide access to fresh water, Wegener said. A 17,000-gallon storage tank acts as a place to store water for long term.
If the main electric grid fails, power can come from solar panels or two underground whole-house generators. The generators are stored in Kevlar-fortified bunkers. To accommodate the smoke that would rise from the generators, decorative shafts were built above ground near the outdoor fireplace to direct the smoke away from the house.
Geothermal heating provides climate control via 27 heat pumps throughout the property.
A few of the features that aren’t fully finished include space for a 750-square-foot home theater, a wine cellar, two elevator shafts and a bridge onto the driveway that can pop spikes out to prevent vehicles from entering or exiting the property.
The 30-car garage, referred to as the Bat Cave, is nearly complete. The only piece of the design that still needs to be added is the waterfall that conceals the entrance.
The home also caters to luxury living with a front entrance modeled after Venice’s Rialto Bridge, three kitchens, a fireplace in the master bedroom, staff quarters, vaulted ceilings and enough entertaining space to host a 600-person event.
“The mandate from the owner was the best of the best and nothing short of it. “So if you build something you do it right or you do not do it. Period.”
