400 Fifth Avenue

400 Fifth Avenue: icon of new architectural development in Manhattan

As Bizzi & Partners’ first project in the United States, 400 Fifth Avenue achieved a rare balance between architectural development and technical and investment expertise. The project testifies to the real estate firm’s executive capabilities and the essence of its international vision.

Project management and negotiation

The building’s development required a complicated series of approvals and negotiations. A renovation deal was struck with the owners of the former Tiffany & Co. Building across the site, and Bizzi & Partners had to obtain approval from the New York Department of City Planning and the Landmarks Preservation Commission. Once approval was granted, the real estate firm also managed to negotiate the inclusion of more than 100,000 square feet of additional air rights above the building, allowing 400 Fifth Avenue to rise 60 stories above ground. A noteworthy height for the neighborhood, as new construction in the surrounding area, is generally limited to a maximum height of 40 stories. As a result, 400 Fifth Avenue enjoys protected, exclusive, 360-degree views of the city.

Exterior appeal, interior comfort

Gwathmey Siegel’s design for the building received unanimous approval from the Department of City Planning and has set a new standard for architectural development in Midtown Manhattan. Located in a vantage position on the northwest corner of Fifth Avenue and West 36th Street, this striking 700-foot tower displays a contemporary glass-and-limestone façade and is topped by an illuminated stainless-steel crown which sets it apart from neighboring buildings. An icon of architectural development in New York, 400 Fifth Avenue represents the perfect blend of comfort and elegance. The development plan required the collaboration of a global real estate firm: Bizzi & Partners handled every level of workmanship with the utmost awareness.

Langham Place, Ai Fiori restaurant & luxury residences

A 214-room luxury hotel, Langham Place, occupies the building’s first 28 floors. The hotel features chef Michael White’s celebrated Ai Fiori restaurant, in addition to a bar/lounge and state-of-the-art spa and fitness center. Floors 30 to 60 count164 luxury residential condominiums ranging from one to three bedrooms, and 4 exclusive penthouses. Condominium owners may enter their residences via the hotel lobby or a private residential lobby and have direct, secure access to hotel amenities. They also enjoy exclusive access to a large residents’ lounge equipped with a catering kitchen and a private wrap-around terrace with an outdoor fireplace. All hotel services, including concierge and room service, are available to condominium owners.
