355 Main St - 355 Main - The Destination Workplace Coworking | Armonk, NY 10504

Success is the space you work in. 355 main is designed for professionals who want more than four walls and a door. Here, you get a beautifully curated, move-in ready space in a boutique campus setting. It feels less like a traditional office, and more like a private club for getting your best work, relationships, and ideas off the ground. The original Armonk Professional Center, built in the 1960s, is a 2-story office building with a rich history. The recent addition to the lobby by famed Architect Vatche Simonian seamlessly merges old and new. The new two-story glass enclosure and stone-clad elevator tower contrast with and yet complement the structure's original brick facade. The elevator tower is clad with oversized stone panels that continue to the interior of the lobby and conceal the mechanical room doors, creating a monolithic anchor for the site.
