Michael Dell, founder and CEO of Dell Technologies, has been revealed as the buyer of the record $100.5 million penthouse atop One57, as per a report by the Wall Street Journal. The sale, which rounds out to $9,200 SF, broke the record $88 million when first announced in May 2012 before closing in 2014. Leighton Candler represented Dell in the One57, which was developed by Extell Development, in the deal. Filings with the Department of Buildings show that Dell has trusted Miró Rivera Architects to oversee a renovation of the penthouse which spans 10,923 SF including the entire 89th and 90th floors. Dell, whose net worth is an estimated $23.3 billion, has his family's wealth managed via his family office/ private investment firm MSD Capital, which is based in New York where they are an active real estate investor making investments in Grand Central Terminal and 45 Park Place. Dell is also the owner of other luxury properties such as "Raptor Residence" in Hawaii and is under contract to pick up the penthouse at One Dalton in Boston which is soon to become New England's tallest building.
