From the mother-of-pearl shower with aromatic steam to the vaulted mahogany master closet, this dark and luxurious lair is stocked from stem to stern with custom perks that go way beyond the $7.9 million loft’s private key-locked elevator and smart home system. Located in a classic pre-war Soho loft building at 459 West Broadway, the 3,150-square-foot space is even outfitted with a secret home gym hidden behind a moving bookcase.

Leonard Stern, billionaire businessman and real estate developer and namesake of NYU’s Stern School of Business, has sold his “ultimate Soho penthouse” for $14,650,000 according to city records released today. In April 2014, a year after Stern originally listed the apartment, New York Magazine released a video tour of the 4,315-square-foot, four-bedroom duplex, revealing everything from a zen solarium to a restaurant-caliber kitchen.

Stern bought the penthouse of 459 West Broadway in 2010 for $14,250,000, but the small profit likely won’t affect him too much since his net worth is estimated at $3.8 billion.
