A full-floor presence with windows wrapping three sides offers a rare chance for a tenant to occupy an expansive, highly partitioned office environment with extensive perimeter rooms and fully built departmental zones. Entry is received through a formal reception positioned in the center of the floorplate directly off the elevator lobby, which immediately orients visitors toward multiple circulation paths. Natural light flows in from every direction due to long rows of windowed offices surrounding the majority of the perimeter, while expansive open work areas anchor the interior core and provide room for large teams.

Stepping from reception toward the south and southeast perimeter, a long row of glass-fronted private offices provides dedicated work environments for senior staff, each proportioned to accommodate full desks, guest seating, and storage. Beyond these rooms lies a generously sized conference room positioned on the southern frontage, designed to host sizable meetings, formal presentations, or collaborative gatherings. Continuing along the south and west sides, more perimeter offices appear in a uniform sequence, each mirroring the style and scale of those opposite, creating consistent executive and managerial workspace opportunities.

Moving inward, the central portion of the floor is organized around multiple open office areas capable of supporting large workstation clusters. These zones are interspersed with a file room, a copy room, an electrical closet, and a LAN closet, all situated strategically for departmental efficiency. The pantry sits off the west interior corridor and includes full cabinetry, storage, and seating space for breaks and informal meetings. Adjacent restrooms for men and women, as well as storage rooms and a janitor’s closet, complete the service core.

Along the east and northeast perimeter, yet another block of offices forms a dedicated wing ideal for legal, consulting, medical administrative, or government-use tenants who require secure, enclosed rooms. Multiple open office sections fill the northeast corner, benefiting from continuous daylight along two exposures. The far west suite mirrors this arrangement with additional large offices and open team areas. With more than thirty perimeter offices, an oversized boardroom, numerous open office sections, and a fully supported infrastructure core, the floor provides an exceptionally flexible layout suited for organizations with significant headcount needs, confidential departmental divisions, or client-facing operational requirements.

Notes: Ideal for governments, medical, nonprofits, investors, or nearly every office use. • Delivered Vacant • Existing Furniture Available • Spectacular 360 Views with Full Height Windows on all Four Sides • Highly Efficient Floor Plan • Real Estate Tax Exemption for Qualified Users
