Full-floor presence within the newly constructed glass-box addition delivers thirteen thousand eighty-eight square feet with floor-to-ceiling glass wrapping the entire perimeter and two private terraces facing north and south, establishing a true indoor–outdoor office environment that defines how the space operates. Entry off the elevator bank opens into a defined reception and circulation spine that separates client-facing areas from the core workspace, allowing for controlled visitor flow while maintaining privacy across the floor.

At the center of the layout sits an open work area built for fifty-four workstations, with the ability to densify to approximately eighty positions if required. This core is arranged in efficient benching rows that support team-based seating, strong departmental organization, and uninterrupted sightlines across the entire floorplate. The scale of this central workspace allows for immediate occupancy while also accommodating future growth without reconfiguration.

Encircling this core is a fully built suite of enclosed rooms that includes one boardroom, one conference room, two lounge-style meeting rooms, and five additional meeting rooms that can flex between breakout rooms, team rooms, or private offices depending on operational needs. A dedicated wellness room is also integrated into the layout, providing a private, purpose-built space for employee use.

Support and amenity infrastructure is substantial and evenly distributed, anchored by two fully built pantries positioned at opposite ends of the floor to support both daily operations and larger internal gatherings. An internal event space is incorporated into the plan, allowing for town halls, presentations, and social functions without disrupting the primary workstation environment. Ten phone booths are strategically placed throughout the floor, providing immediate access to acoustic privacy for calls and focused work.

Circulation is clean and intuitive, with clear pathways connecting all program elements while maintaining separation between public-facing and internal functions. The defining feature remains the two private terraces, oriented north and south, which extend directly off the interior and function as true outdoor workspaces for meetings, collaboration, and employee downtime. Delivered fully furnished with a brand-new, high-end installation, the sixth floor operates as a turnkey headquarters environment that combines fifty-four workstations, nine total meeting rooms, one wellness room, ten phone booths, two pantries, and dual terraces within a cohesive full-floor layout.

Notes: Entire 6th Floor – Existing installation features open area for 54 workstations (with room to densify to 80), 1 boardroom, 1 conference room, 2 lounges/meeting rooms, 5 meeting rooms, 1 wellness room, 10 phone booths, event space, 2 pantries, and two private terraces.

About the Building

520 West 20th Street sits directly along the High Line and captures the essence of Chelsea by combining preserved industrial architecture with a distinctly modern addition. The original warehouse structure remains largely intact, with its brick façade left untouched, allowing the building to retain the raw, authentic character that defines the neighborhood. Inside, that same approach continues, where exposed concrete, aged brick, and timber elements reinforce a sense of history while creating a warm, textured office environment.

Rather than separating old from new, the design weaves them together. The materials used in the original structure carry through into the updated portions of the building, creating a consistent visual language across both the historic base and the contemporary expansion above. Rising from the existing structure, two vertical cores anchor the building’s transformation. These cores contain circulation and mechanical systems, while also serving as the structural backbone for the steel-and-glass addition that extends over the original roofline.

The warehouse itself, which had previously been used as a parking facility, was intentionally left in its found condition. Weathered brick, discoloration, and remnants of old signage were preserved, reinforcing the authenticity of the structure rather than erasing it. Inside, the original ceiling heights remain generous, enhancing the sense of volume and allowing the historic materials to define the space.

At the ground level, the lobby introduces a more refined but still contextual design. Board-formed concrete surfaces, a custom reception installation, and a feature wall constructed from reclaimed railroad ties—referencing the nearby High Line—create a space that feels both industrial and curated. The inclusion of gallery space further aligns the building with Chelsea’s art-driven identity.

Structurally, the new addition is supported by the two vertical cores, which rise through the building and extend above the original roof. These elements, inspired by the building’s former elevator shafts, now function as the framework that carries the modern glass volume. The result is a composition where a contemporary structure appears to hover above a preserved industrial base.

Overall, the building does not attempt to overshadow its surroundings. Instead, it embraces Chelsea’s transformation by maintaining a clear connection to its past while introducing a modern architectural layer. The preserved warehouse grounds the property in the neighborhood’s industrial history, while the elevated glass addition reflects the forward-looking character of the area today.
