“We’re excited to welcome these new tenants to One Madison Avenue which is Midtown South’s most exciting new office development,” said Steven Durels, Executive Vice President, Director of Leasing and Real Property at SL Green. “Additionally, Le Jardin sur Madison and La Tête d’Or by Daniel are extraordinary additions to what will be an unparalleled combination of building amenities.”


SL Green also unveiled new renderings and details of the building’s featured spaces:


Le Jardin sur Madison, located on the building’s 28th floor, is a one-of-a-kind 6,200-square-foot event space designed by renowned architect David Rockwell together with a lushly landscaped 5,000-square-foot rooftop garden designed by SMI Landscape Architecture. The design was inspired by the green oasis and vibrant urban hub that is Madison Square Park. Accessible by day to One Madison tenants for meetings, coffee, and a serene place to work or recharge, the exclusive rooftop will be available in the evening for private parties and a variety of events. Catering and food and beverage offerings will be provided by famed chef, Daniel Boulud.


“With Le Jardin sur Madison, we are excited to provide One Madison tenants with an indoor-outdoor oasis for dining, working, events, and conversation,” said David Rockwell, Founder and President, Rockwell Group. “Rockwell Group’s design concept celebrates structure, truth to materials and natural light to create an inviting space that emphasizes spectacular views of the city and Madison Square Park. A peaked roof offers a cathedral-like experience, with a subtly curved wood ceiling that culminates in a 17’ skylight and mimics the sky-bound trees of the park through warm woods, reflective metals, and muscular trusses.”

La Tête d’Or by Daniel will be the renowned chef’s latest culinary offering, adding a first to his extensive portfolio – a steakhouse. The elegant and spacious dining room is designed by Rockwell Group and is influenced by the comfort of the American steakhouse blended with the classic Parisian dining scene. La Tête d’Or by Daniel will feature a 150-person main dining area, a cocktail bar in a dramatic lounge, private dining room, and an exclusive private omakase steak and seafood table to enjoy a unique dining experience. The new restaurant is expected to open to the public in November 2024.

“I am a French chef with a big American heart and I have loved steakhouses since my early days in this country. When I travel across the States I often make it a point to visit a steakhouse. I always enjoy this quintessential and glorious emblem of the American dining scene, excelling in their use of prime ingredients with soulful simplicity and proud service,” said Chef Daniel Boulud. “La Tête d’Or will be a true American steakhouse with a French ‘triple s’ branding: soul, seasoning and sauces! I look forward to welcoming guests into this new Madison Square Park neighborhood destination where they will experience our creative approach to traditional flavors.”
