Offices – 400

400, also designed by Gensler, is a 115,140 square-foot office building which in many ways mirrors 200. 400 has been sited to maximize river and Park views, with north and west exposures opening to striking landscaped plazas.



Two-sided lobby finished in White Oak Truewood Panels, light gray back-painted glass, basaltina stone flooring and artwork, including a fish created by Ed Larson and a bench by Terry Dwan. There are pieces by the same artists in Building 200.

The 400 Café includes a deli, salad bar, grab-and-go, and various seating configurations, and is available for River’s Edge tenants, residents and visitors. (Temporarily closed.)  A fully outfitted fitness center — with lockers, showers and a multi-purpose room for exercising and meetings — is available for the exclusive use of 400 tenants.

Floor Plans & Test Fits

The 32,000 RSF floors include just 4 interior columns, have 9-foot finished ceilings and 7 feet of glass, providing tenants with great natural light, views, and exceptional efficiency in both perimeter office and open layouts. These test fits are for presentation purposes. The actual layouts differ.
