A new hotel designed by Skidmore Owings & Merrill landed at the beginning of 2021 on West 33rd Street in Manhattan’s still-rising Hudson Yards neighborhood. Pendry Manhattan West tops out at 21 stories and is part of a 5-building master plan that will bring new hospitality and mixed-use buildings to Tenth Avenue, adjacent to Hudson Yards. Wedged between One and Five Manhattan West, the hotel yields 164 guest rooms. The curved glass facade is a deep blue tone with black stone ribbons reminiscent of a dark, starless night or deep ocean trench.

The curtain wall is comprised of alternating curved and flat glass panels, designed to set the building apart from its flatly glazed neighbors. From the outside, the panels exhibit a dark, reflective tint that provides privacy for the guests while also maintaining visual consistency as the interior program shifts. On the other side, the geometry of the panels provides wider views of the west side of Manhattan. SOM worked closely with the facade consultant, Front Inc., as early as the bid process in order to deliver this exquisite design intent. With specific challenges arising from the convex and concave floor plans, SOM’s engineering and design team collaborated closely with both the fabrication team at Fabbrica and the construction manager. Fabbrica was able to manufacture panels that registered as consistent in color, despite the changing opacities from floor to floor. Due to the technical fabrication limitations of high-performance surface coating, the team worked together to arrive at the deep shade of blue-black for the substrate glass as a solution.

Each curved insulated panel varies in overall dimension, but have only three different bending radii. The tight enclosure radii span approximately five feet each (see the diagram below) and required particular attention to detail when fabricated. “We solved this with enhanced QA/QC [quality assurance] measures and by selecting the best fabrication methodology and suppliers,” says Ingrid Pu, Technical Design Associate at SOM.

The granite stone was quarried by A. Lacroix Granit and framed into each curtain wall unit right in Fabbrica’s shop. All of the curved glazing on the tower was structurally siliconed to a unitized aluminum glass assembly hung off the building’s wavy concrete slab.
