Wide-open communal spaces and personal quiet zones coexist in a flexible workplace designed for a double-height, sunlit penthouse of a 1913 building near Manhattan’s Hudson Yards. Spatial juxtapositions and pathways encourage people to move throughout the day, generating happenstance meetings and the exchange of ideas. A new bridge connects the two sides of the historic mezzanine floor, facilitating encounters, while a wide stair becomes a place for gatherings. Rich, textured materials and a diverse mix of vintage and new furnishings bring a sense of human personality to the workspaces.
