Superstructure progress continues at 215 Chrystie, with concrete reaching the sixth floor slab. The 28-story tower from developers Ian Schrager and the Witkoff Group will include 370 hotel rooms under the PUBLIC brand at the lower levels and 11 condos on the upper floors. Pritzker Prize winning architects Herzog & de Meuron have designed the tower as a rectangular extrusion with a setback volume for the upper condo floors. Sloping floor-to-ceiling glass panels are set in between angular, exposed concrete columns. Interiors on the luxury condos will be designed by John Pawson, with both half floor and full floor units. The top of the tower will be capped with a three story mechanical penthouse. Completion is slated for the fourth quarter of next year.
