Herzog and de Meuron's newest addition to New York City will be an curvaceous 12-story condo building at 357 West Street on the corner of Leroy Street. The starchitect firm was confirmed for the project in March, and now New York YIMBY has the first renderings of the development. The building will hold 88 units, and the swooping facade appears to be made of concrete, which seems likely since Herzog and de Meuron's other New York projectsthe Jenga-like 56 Leonard and recently-revealed 215 Chrystie Streetalso feature concrete exteriors. Along West Street, the sidewalk will be widened and the ground floor will feature plantings, and a column of terraces runs up the building's eastern edge along Leroy Street. Ian Schrager is the developerhe's also working with the firm on 215 Chrystieand a tipster told YIMBY that the building should be complete in 2017.
