The plans show that the two central mansions will be joined by a tunnel that branches off into a 5,000-square-foot underground shelter, featuring living space, a mechanical room, and an escape hatch that can be accessed via a ladder. "There's cameras everywhere," David says—and the documents back this up. More than 20 cameras are included on plans for one smaller ranch operations building alone. Many of the compound's doors are planned to be keypad-operated or soundproofed. Others, like those in the library, are described as "blind doors," made to imitate the design of the surrounding walls. The door in the underground shelter will be constructed out of metal and filled in with concrete—a style common in bunkers and bomb shelters.
According to sources and planning documents reviewed by WIRED, the compound will be self-sufficient, with its own water tank, 55 feet in diameter and 18 feet tall—along with a pump system. A variety of food
is already produced across its 1,400 acres through ranching and agriculture.
