Three Pathways to Your Custom Workspace
For organizations seeking a truly dedicated presence in Armonk, we offer three distinct pathways to a custom workspace—one that can be tailored and re-tailored endlessly as your organization evolves.
- 3rd Floor Addition at 355 Main
A new floor built above the existing 355 Main building, offering premium elevation and views with direct access to shared amenities.
- 357 Main Street
The neighboring building offers a dedicated address with private entrance, while maintaining proximity to the 355 Main campus and amenities.
- New Lease on Turnover
As existing tenants transition, prime suites within 355 Main become available for full customization to your brand and workflow.
