Celebrity designer Nate Berkus really likes Greenwich Village. And three-bedroom duplex apartments with private outdoor space. Just two weeks ago, Berkus sold his West 9th Street pad for $4.95 million, and now the Observer reports that he closed on a new apartment just a couple blocks away. Berkus paid $5 million ($400K less than the asking price) for the penthouse unit of 39 Fifth Avenue, a 15-story co-op building between 10th and 11th Streets. The new unit is very similar to his last place, but it’s on a much higher floor, and it has a wraparound rooftop terrace. The huge kitchen has a “custom-fabricated greenhouse,” there’s a French limestone foyer, and both the living room and dining room have wood-burning fireplaces.
