A
rare Upper East Side co-op penthouse, nestled near the Metropolitan Museum of Art, is on the market for $10 million after more than six decades in the same family's hands. The 21st-floor unit at 1050 Fifth Ave., completed in 1959, boasts stunning views of Central Park, the Met, and the Manhattan skyline from its three private terraces.

    The property measures around 3,000 square feet, with an additional 311 square feet of outdoor space. It features three to five bedrooms, depending on the buyer's preference, and 3.5 bathrooms. The expansive corner living room offers a floor-to-ceiling window with western and southern skyline views, as well as access to one of the terraces.

    The home has undergone various transformations over the years, reflecting its multi-generational history. One room has been used as a maid's room, nanny's room, playroom, and artist studio, among other purposes. A hidden hall closet serves as a secret passageway to one of the bedrooms, adding an extra layer of character.

    The current owners, who purchased the unit directly from developer Bernard Spitzer, have raised their children in the home but now find it unnecessary due to their family's changing needs. Tate Kelly and Josue Gonzalez of Coldwell Banker Warburg hold the listing for this unique property.
