The project expanded Biology, Chemistry, and Drug Disposition laboratories for pharmaceutical research and corporate offices. The expansion was to the original U. S. headquarters facilities for Eisai Research Institute, designed by Ellenzweig (constructed in 1989); the Institute is the research component of Eisai Co., Ltd., a major Japanese pharmaceutical company. Ellenzweig provided master planning, programming, architectural design, laboratory planning and design, and construction administration services.
Located on a 23-acre site north of Boston, the research and office facilities link to the existing 1989 buildings with a series of interior and exterior connections that transform the research campus into one cohesive complex. A glass-enclosed connector joins the new building to existing labs, and a pedestrian bridge connects it to an administrative building. Interior spaces provides a highly open and visible environment to promote interaction among researchers; glass walls connecting labs to support areas allow views through the building from lab to lab and office to lab.
The facility is designed as a series of pavilions - one for each of the research disciplines, and one for administrative and public functions. Administrative spaces are connected to the research areas by an atrium that also serves as a public entrance and company gathering-place. Each research pavilion is linked to the next via sky-lit, interactive lounge areas.
