(BBC) – Mark Zuckerberg is said to have started work on Koolau Ranch, his sprawling 1,400-acre compound on the Hawaiian island of Kauai, as far back as 2014.
It is set to include a shelter, complete with its own energy and food supplies, though the carpenters and electricians working on the site were banned from talking about it by non-disclosure agreements, according to a report by Wired magazine.
A six-foot wall blocked the project from view of a nearby road.
Asked last year if he was creating a doomsday bunker, the Facebook founder gave a flat “no”. The underground space spanning some 5,000 square feet is, he explained, “just like a little shelter, it’s like a basement”.
That hasn’t stopped the speculation – likewise about his decision to buy 11 properties in the Crescent Park neighbourhood of Palo Alto in California, apparently adding a 7,000 square feet underground space beneath.
