Conceived as a walk-to-work boutique office building at the Northern edge, 667 Madison was built to meet a specific set of needs desired by family offices, alternative asset management businesses, and boutique office occupiers.
With ownership by Leonard Stern and son Edward, they pride themselves in operating New York City’s finest boutique office building, providing first-class service that is unmatched in the Manhattan marketplace.
Inspired by grand architectural elements in the Saint-Germain-des-Prés district of Paris, 667 Madison’s granite-clad exterior office building stands at 25 stories with 273,114 RSF.
Bespoke interiors have been curated to feature elements of a Manhattan residence rather than of standard office space. This vision has been realized through expansive floor-to-ceiling windows and spacious ceiling heights, as well as the use of materials such as sheetrock and finishes like automatic shades and others that are found in New York’s very best residential buildings.
667 Madison’s office interior finishes reflect ownership’s vision to offer its tenants a standard that is modern, yet timeless, and with the very best in quality that is available in the marketplace today. These standards include wide-planked wood floors, floor-to-ceiling glass office fronts, generous use of sheetrock, and related finishes that ensure office interiors are both highly functional, yet residential in the ambiance.
Bartholdi’s original maquette of Lady Liberty greets 667 Madison visitors upon arrival. Gilbert Stewart’s original portrait of George Washington—one of only two portraits the first President ever sat for—hangs behind the reception desk, staffed by the city’s best and most committed operations team.
“The west wall of our lobby was originally designed to display a fantastic piece of art. Yet I could never find the perfect piece, given the size and volume of the space and my commitment to do something really different.”
— Leonard Stern
Located on the northeast corner of 61st Street and Madison Avenue, 667 Madison sits at the intersection of two of the city’s most prominent neighborhoods and is one block from Central Park. The asset’s location is unique in that the area’s traffic and streetscape feel more like a residential neighborhood rather than a hectic commercial district. The city’s most important shops, restaurants, cultural experiences, and hotels are within walking distance.
667 Madison’s elevators, cooling tower, air handling systems, air purifying systems, and internal fiber network have all been recently upgraded, and ownership is committed to maintaining the building’s systems to the highest possible standard.
Private Elevator Service
Elevators have been pre-programmed to accommodate “express rides” from any floor directly to the lobby, and lobby attendants can arrange private car service to any floor in the building upon request.
