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 with the award-winning architecture firm, Snøhetta, to deliver the new vision for the building which includes optimising and enhancing its commercial and retail uses and fostering the public spaces.

Snøhetta’s approach focuses on creating a working 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 nearly double in size and transform into a lush outdoor garden.
