Former New York City Mayor Michael Bloomberg is another step closer to creating his Upper East Side megamansion. While his elegant, five-story limestone townhouse t is already one of the most luxurious homes in the city, Mr. Bloomberg been steadily buying up the units in the townhouse co-op next door for nearly thirty years, in the hopes of creating a mansion of mammoth proportions. His quest in buying up the buidling next door (to the right) dates back to 1989, beginning with the first floor. In 2000, he paid $1.2 million for the 2,000-square-foot second floor, and has picked up two more units in the past few years, bringing him to a grand total of four out of six apartments in the building, which gave him an estimated 12,500 square feet of space in his home—lots of room to run around. Now it looks like he’s even closer to recreating a home rather reminiscent of the Gilded Age behemoths that once lined Fifth Avenue’s streets–per public record, Mr. Bloomberg, through Lamony III LLC, has bought unit 3 from the townhouse next door from Charles and Susana Finkel, for the price of $14 million.
