Astellas Headquarters for the Americas

A LEED-NC Gold headquarters complex serves the recent merger of two Japanese pharmaceutical companies and the new company’s commitment to reduce its carbon footprint. The complex establishes a confident, forward-thinking image supporting the company’s vision for “changing tomorrow.”

Located outside Chicago at a prominent highway intersection, the two-building complex is designed as a dynamic, atypical suburban office that maximizes use of its tight, V-shaped site. Containing separate corporate functions joined by a shared entry pavilion, the six-story buildings lean toward each other and face the expressway.

The buildings are designed for efficiency and flexibility with strong asymmetrical forms, defined by sharply angled walls. Vertical fins on the long walls provide a continuous interplay of light and shadow while trapezoidal projections express the internal program, with conference rooms on every floor. Clad in a distinct, silver glass, the projections accommodate signage and reinforce the buildings’ asymmetry and angles.

Sustainable design features include a geothermal field, high-performance curtain wall system, water retention for site irrigation, and sustainable landscape. High-efficiency air filters, abundant daylight and landscaped views enhance employee comfort. On-site amenities include a cafeteria, fitness center, bike storage and changing room, covered parking, and outdoor terraces.
