The Making of: 55 Hudson Yards The Lobby

Hudson Yards has transformed what was previously a vast, desolate railyard on Manhattan’s far west side into a dynamic neighborhood characterized by modernity, sustainability, art, and culture.

Located on the northernmost edge of the site, 55 Hudson Yards presents an understated massing and expressive façade, synthesizing Manhattan’s sleek, contemporary architecture with the industrial roots of the neighboring West Chelsea and Meatpacking District. Unlike many new office towers clad in glass, 55 Hudson Yards comes to life through its modulated scale, crafted façade, and natural materials that speak to its formerly industrial context and the spirit of fabrication.

A logical progression of scale – from tower to podium to street level – leads tenants into the lobby of 55 Hudson Yards, where the building’s tactile materials – stone, wood, and glass – maintain a simple palette of greys and blacks highlighted by wood tones and moments of color.

The lobby walls are clad in Jet Mist® granite with a split face finish. Depending on the technique used to quarry stone, the slabs separate at a weak seam, revealing a rough, typically undesirable appearance. Usually, this surface is cut away and discarded in favor of a fresh clean cut.

In this case, however, the design team favored the split face for its natural range in texture, veining, and coloration and selected it for 55 Hudson Yards.

Four visits to the quarry in Virginia were required to select the appropriate Jet Mist® slabs which were then cleaned with a power wash, milled, and polished. Several dry lays were taken from 2016 to 2018 to approve sections of the stone wall slabs. These inspections were crucial to ensuring that the color, texture, and veining fell within an acceptable tolerance.

Once the panels were inspected for uniformity, each selected panel was cut to the appropriate size: approximately 7’ wide and 4’ tall. The split face stone was then measured to ensure that the variations on the front face of the panel were within 4” – 6.5” from the leveled back face of the panel to maintain a reasonable thickness and a slightly varied, yet consistent, visible texture. After fabrication, the panels were transported to the project site for installation.

Through a series of mock ups, the design team studied the geometry of the walls, the potential and the limitations of the stone, and construction and finishing methods. This process informed design decisions and ultimately allowed the natural stone to drive the final lobby design. Jet Mist® granite’s versatility is exhibited throughout the lobby: the walls of the East Lobby, East Anteroom, and the West Lobby are dominated by split face granite panels, all soffits and thresholds of the large entrances are polished to a highly reflective dark finish, and the elevator lobby is polished with a smooth thermal finish.

In all, 1,160 Jet Mist® granite panels, each weighing approximately 1,600 pounds, were lifted into place mechanically, using a hand-operated pulley system, and mounted on steel brackets that are bolted to vertical beams. The resulting wall panels are impressive in scale and texture, yet simple in composition.

The floor pavers were chosen specifically for their silver coloration, which contrasts the darker matte walls. Approximately 500 Silvercloud granite panels continue the modulation of the walls, as the framing joints run through the entirety of the lobby. The pavers were cut, fabricated, and given a honed finish in Quebec, Canada.

Backlit onyx feature walls bring in rich color and light variation, complementing the darker greyscale lobby floor and walls. The relatively rare blue onyx, sourced from overseas, is typically pastel, but when illuminated with 6300K light, the stone reveals vivid shades of blue, purple, and yellow. The onyx panels are framed to align with the Jet Mist® panels, maintaining structural order but offering visual variation.

The cast glass similarly creates an illuminated guiding pathway through the lobby. After experimenting with different glass and lighting conditions, the team chose sawtooth glass for its slight texture variations. Exploring the scale and material limitations of the glass resulted in a 2” wide sawtooth, vertically striated over panels which measure approximately 5’ – 0” x 5’ – 0”. The cast glass is backlit with a series of linear lights and a lightbox, creating a glowing effect.

This approach to materiality is institutionalized at KPF. Each project, from large office towers to low-scale residential buildings, incorporates a level of craft and detail driven to elevate the tenant experience. Always keeping a project’s big ideas in mind – in the case of 55 Hudson Yards, scale and expression – the design team leverages these material decisions to convey its essence in every level of design.
