Landscape, interior and infrastructure in one appointment.
OSAN / Overview
Landscape, interior and infrastructure in one appointment.
At 270 Park Avenue, OSAN’s 2020–2025 work encompassed the complete landscaping, interior decoration and infrastructure scopes. The OSAN budget associated with those packages is USD 395 million.
Three scales define the work: the external setting, the interior environment and the infrastructure serving the development. The appointment is presented through those packages within the wider headquarters project.
Budget refers to the work attributed to OSAN and is separate from the overall project investment.
Scope & responsibility
Our scope
ENGINEERING IN FOCUS
Landscape as a system.
Levels and thresholds
External space is shaped by levels, routes and transitions. Arrival, circulation and the relationship with entrances establish the landscape’s spatial order. A precise threshold connects the building’s internal environment with the city outside.

Surface and substructure
Paving and planted areas form part of a layered external assembly. The visible surface is related to the supporting construction and the management of water. Their interfaces influence the continuity between hard landscape, soft landscape and building edges.
A complete setting
Landscape is experienced through movement, shade, material and planting together. Paths, seating and planted boundaries create relationships rather than isolated objects. The external setting gives the building a broader spatial presence.
The project in context
At a glance
The new JPMorganChase global headquarters, designed by Foster + Partners, opened in October 2025. Its 60-storey tower rises approximately 423 metres. The development sits above active Grand Central rail infrastructure, a major condition shaping the wider structural design.
