Chelsea Office Penthouse With Roofdeck

  • 4,100 SQFT
  • $4,999,005

A rare penthouse office condominium in the heart of Chelsea delivers a full-floor workspace wrapped in oversized windows, exceptionally high ceilings, and a level of detail and finish that sets it apart from typical office product in the neighborhood. The space opens directly into an expansive loft environment where sunlight streams through a long stretch of western and southern windows, immediately establishing a bright and elevated atmosphere that is ideal for creative, tech, design, or boutique professional firms seeking a distinctive identity. The open area near the entry provides more than enough space for a large reception or client-greeting zone, with sightlines stretching uninterrupted across hardwood floors to the window walls beyond.

Toward the western perimeter, a gracious open workspace supports generous team seating and collaborative layouts, with enough width to accommodate a mixture of workstations, lounge groupings, or long production tables without sacrificing circulation. The windows along this edge frame views of Chelsea’s rooftops and water towers, creating an inspiring backdrop that enhances the feel of a true penthouse studio. To the north, an additional open area sits beneath a striking skylight that floods the space with natural illumination, making this zone ideal for teams that need bright conditions throughout the day or for firms that rely on natural light for creative work. This portion of the layout flows directly into a chef-grade kitchen with full-height cabinetry, commercial appliances, and ample counter space, making it well-suited for company gatherings, private events, or catered client meetings.

Along the eastern perimeter sits a large enclosed room that can serve as a private executive office, a dedicated conference room, or an internal meeting suite. Its placement away from the primary workspace offers quiet and privacy while still benefiting from full-height windows and built-in storage beneath the sills. A second perimeter room along the south side provides another enclosed office or meeting space, offering flexibility for leadership, confidential work, or breakout sessions. Both of these rooms sit adjacent to the main loft, adding structure to an otherwise open plan without diminishing the expansive feel.

The floor also includes internal spaces that transition naturally from the primary work areas. A sculptural wood-paneled volume positioned near the center houses additional storage and utility functions, allowing the open environment to remain clean and uncluttered. High-end lighting, exposed structural elements, and oversized spans between columns reinforce the authentic loft character that makes this penthouse compelling for a company seeking a standout headquarters floor.

One of the most unique features of the property is its private roof deck, accessed directly from within the suite. The outdoor area is fitted with dedicated seating zones, planting beds, and ample open space, offering a rare opportunity for outdoor meetings, staff gatherings, client entertainment, or quiet breaks in the middle of the workday. With panoramic views over Chelsea and the Flatiron District, the roof deck transforms the penthouse into a workplace with amenities more often found in boutique hospitality environments than in traditional office settings.

The combination of perimeter rooms, expansive open areas, exceptional light from three exposures, a high-end kitchen, and private roof access creates a unique opportunity for a business seeking an elevated and memorable office environment. The full-floor layout provides privacy, identity, and control, making it ideally suited for creative studios, boutique firms, and any company looking to make a lasting impression.
