An iconic building in the heart of Midtown Manhattan

Built in 1984 as AT&T’s global headquarters by the architect Philip Johnson, and subsequently known as The Sony Building following their ownership, 550 Madison is a 37-storey, 850,000 sqft mixed-use tower in a prime Manhattan location.

Chelsfield is working alongside RXR with the award-winning architecture firm, Snøhetta, to deliver the new vision for the building, owned by The Olayan Group, including optimising and enhancing its commercial and retail uses and fostering the public spaces.

Snøhetta’s approach focuses on creating an environment best suited to the needs of today’s commercial and retail tenants.

The expansive column free office floorplates will be enhanced as a result of significant infrastructure upgrades offering tenants the opportunity to create dramatic spaces that are open and flexible.

The existing sky lobby will become the heart of the tower offering high-quality tenant amenities.

The adjacent public realm will increase in size by almost 50% and transform into a lush outdoor garden.
