Schonefeldtners LP and funds managed by Goldman Sachs. According to Kelly Kennedy Mack, President of Corcoran Sunshine Marketing Group, exclusive sales and marketing firm for the development, 56 Leonard's initial offering received an overwhelming response. Since launching sales three weeks ago, the building has booked over $450 million in sales, and 50% of the residences have already been sold. "This iconic tower will be a sculpture in the Manhattan skyline. We are excited to be able to add this future landmark to the landscape of the city and create 145 unique residences in Tribeca," said Izak Senbahar, president of Alexico Group. The Building:World-renowned architectural firm Herzog & de Meuron, creator of such landmarks as Beijing's "Bird's Nest" stadium and London's Tate Modern museum, has reset standards for the American residential skyscraper at 56 Leonard. This vertical glass expression with its unique cantilevered apartments will immerse residents into the cityscape and will offer panoramic views of Manhattan as far as the Atlantic Ocean. The 60-story building, standing 830-feet high (253-meters) at Church Street and Leonard Street in Tribeca's Historic District, will have 145 residences, each with their own unique floor plan and private outdoor space. The total aggregate outdoor space being provided for all residences is 45,000-square feet (4,181-square meters.) From the dramatic lobby with 18-foot (5.9-meter) ceilings and custom-designed pieces by Herzog & de Meuron, residents board one of six elevators with bespoke interiors to reach their homes. In an unprecedented collaboration between artist and architect, the tower will be integrated at its base with a commissioned work by Turner Prize winner Anish Kapoor. The relationship between building and sculpture is so closely cultivated that they appear to form a single unified object, exemplifying true synergy between art and architecture. This sculpture by Kapoor will make a lasting contribution to New York's streetscape and will be his first permanent public work in New York. 56 Leonard will house a private amenity space custom designed by Herzog & de Meuron. The 17,000-square foot (1,580-square meters) space on the ninth and tenth floors, include a 75-foot (22.86-meter) infinity pool with landscaped outdoor sundeck and hot tub overlooking the Hudson River; fitness center with yoga studio, steam room and treatment room; library lounge; indoor/outdoor theater; private dining salon; and Tribeca Tot Room children's play area.
