Facebook boss Mark Zuckerberg is reportedly building a $100 million complex in Hawaii that houses an underground "apocalypse" bunker and has its own food and energy sources.
The project is completely secretive, which some argue the social media mogul is trying to cover up his doomsday preparations.
The Facebook founder's compound, called Koolau Ranch, is already partially built and is becoming one of the most expensive personal construction projects in modern history, Wired's investigation of property records and interviews with contractors reveals.
The complex on the island of Kauai will consist of more than a dozen buildings with two central villas connected by a tunnel leading to a 5,000-square-foot underground shelter with an escape hatch accessible by stairs, Wired reported citing construction plans. . The property will contain at least 30 bedrooms and 30 bathrooms, and will also include a series of guesthouses and a group of 11 disc-shaped treehouses connected by rope bridges.
The underground bunker will have living space, a generator room, as well as a visible “explosion-proof” concrete and steel door, Wired reports.

Other exits and entrances to the complex's buildings will have doors that unlock codes, everything is soundproof, and the library will have a secret or "blind" door, according to construction documents. Cameras are already "everywhere," according to one employee, and plans show a small building being "watched" by more than 20 cameras.
Koolau Ranch has another feature that indicates that Meta's CEO may know about some kind of apocalypse. According to Wired's sources, the developers hope that the complex will be completely self-sufficient. The water tank – about 17 meters in diameter and 5.5 meters high – along with a pump system will be located on the property, where existing livestock and agriculture on 1,400 hectares already provide food sources.
Zuckerberg has built a two-meter wall around the compound and forced all workers, regardless of position, to sign an agreement not to reveal any details about work on the property.
The billionaire spent $170 million to buy land to build this farm, which he, his wife and children consider their family home, Zuckerberg's spokesperson told Wired.
