Architects making a New York debut this year include Tadao Ando, the Pritzker Prize-winning architect behind 152 Elizabeth Street, a boutique condominium developed by the New York firm Sumaida and Khurana. The building will incorporate Mr. Ando’s signature poured concrete, galvanized steel and voluminous glass, and house just seven two- to five-bedroom apartments with half-floor residences starting at $5.9 million and full-floor apartments beginning at $15 million.
