At 950,000 square feet, 343 Madison offers 40 premier workplace floors ranging from 27,500 square feet in the podium to 22,000 square feet in the high-rise, all with direct access to Grand Central’s Madison Concourse between 44th and 45th Streets.

Designed by Kohn Pedersen Fox, the 46-story tower will offer a hospitality-forward amenity program. A double-height lounge and conference space on the 45th and 46th floors will include spaces to dine, connect, and collaborate both indoors and out, with biophilic terraces overlooking Midtown Manhattan. A robust food and beverage program, lobby café and bicycle storage with cabanas and showers round out the amenity offering.

Sustainability is a key pillar of the property, with a fully electric building design, zero on-site combustion, and a high-efficiency direct outside air system. Climate resiliency, decarbonization, and health and wellness are at the core of the building design.
