355 Main is not just an office; it is a high-performance instrument for modern business. Reimagined within the architectural shell of the Armonk Professional Center, this turnkey suite eliminates the friction of traditional leasing by delivering a "Day 1" solution that is fully furnished, powered, and thoughtfully zoned.

We moved beyond the static office layout to create a "Front-of-House / Back-of-House" ecosystem:

Front-of-House: A polished client-facing Café Zone featuring matte black finishes, white Caesarstone, and tech-integrated banquettes for coffee and connection.

Back-of-House: A discrete, fully equipped kitchen and high-utility Resource Room ensure that the "engine" of the office—meal prep, printing, and production—never interferes with the client experience.

Engineered for Human Performance: Every piece of furniture was selected with a specific "Why." The suite features the Vitra Tyde 2 sit-stand workstations and Soft Work sofa systems, paired with Mikado and Mynt chairs. These "active sitting" solutions allow for infinite micro-movements, keeping energy high and preventing static fatigue.

The "Dynamic Zone" Advantage: At the heart of the suite lies a flexible core that adapts to your workflow. Pre-set for agility, this zone pivots from intimate Stand-Ups and Focus Areas to a full Town Hall or Symposium in minutes. Whether you need a "War Room" for a project sprint or a private "Cockpit" for executive focus, 355 Main delivers the autonomy of a private headquarters with the energy of a club.
