A flock of celebrated international architects are now dazzling the Manhattan skyline with their first-ever New York City residential projects. Japan’s Tadao Ando, whose honors include the prestigious Pritzker and Kyoto prizes, makes his Gotham debut with 152 Elizabeth St., which will soon launch sales. Half-floor apartments at this seven-unit condominium will start at $5.9 million, with full-floors starting at $15 million.
