A Glass Penthouse Above West Chelsea

The sixth and seventh floors are the building’s top two floors and occupy its contemporary glass addition. Windows extending from floor to ceiling wrap all four sides, bringing natural light into the offices and giving the space an open, penthouse feel.

For businesses searching for brand new construction office space or a glass and steel penthouse, this offering deserves a closer look. The building’s addition is complete, and the available offices feature a luxury installation delivered fully furnished.

Two private terraces on each floor extend the workplace outdoors. They provide space to take a break, have an informal conversation or step outside between meetings. Direct access to the shared roof deck adds another outdoor amenity.

Brand New, Fully Furnished Office Space

An attractive office still needs to work well throughout the day. Both floors combine open workstation areas with conference rooms, phone booths, lounges and private meeting spaces.

For financial firms, that mix provides room for investment teams, confidential calls, investor meetings and collaboration. The furniture is included, giving an incoming tenant a practical starting point for its relocation.

Entire Seventh Floor: 13,088 RSF

The seventh-floor features 54 workstations, an extensive mix of meeting rooms and an executive office or lounge with a private restroom and shower.

• Two meeting rooms
• One executive office or lounge with a private restroom and shower

A company leasing both floors would have 134 existing workstations, plus the conference facilities, lounges and support areas across the two levels. Each floor is also available separately.

Private Terraces and Roof Deck Access

Outdoor space is one of the strongest reasons to see this luxury office sublease in person.

A tenant leasing both floors would have four private terraces, in addition to direct access to the shared roof deck. That creates several places for employees to spend time outside and gives the office another dimension when hosting clients or colleagues.

For companies comparing trophy office space in Manhattan, the combination of private outdoor areas, extensive glass and a newly furnished interior makes this offering worth exploring.

The Warehouse at 520 West 20th Street

The Warehouse combines the character of an industrial Chelsea building with a modern office addition. Its redevelopment introduced an updated lobby, elevators, windows and mechanical systems while preserving the property’s architectural identity.

The original warehouse and the glass addition give the building two distinct personalities. The available top floors offer the contemporary side of that experience, with expansive windows and private terraces above the surrounding streets.

A lobby attended around the clock supports access throughout the week. For tenants searching specifically for extra high ceilings, ceiling heights within the available premises should be confirmed during a tour.

A Chelsea Gallery District Address

520 West 20th Street sits in the heart of the Chelsea Gallery District, near Chelsea Piers, the High Line and the Hudson River waterfront.

The neighborhood gives the office a setting surrounded by galleries, restaurants and outdoor destinations. It’s an appealing option for firms that want a distinctive Manhattan address and a workplace employees will enjoy using.

This furnished office space is perfect for a hedge fund, private equity firm, VC fund, trading operation or any other high end user seeking a polished West Chelsea office. The private terraces and glass surroundings make an impression, while the existing layout provides the meeting rooms and work areas needed for daily business.
