The project is a 90,000 SF corporate headquarters for Serta International Mattress Company located on a 20 acre Illinois prairie site. The program weaves together a 65,000 SF office wing and a 25,000 high bay R&D facility. The building (700' long x 67' wide) has been designed to facilitate equal access to natural light, ventilation, and views of the wetlands for all employees. To accomplish this, the floor plan has been layered from a glass edged public circulation path on the east, defined by a translucent core zone, to an open office area on the west toward the wetlands. All private offices and conference rooms are clear or translucent glass to preserve the views, with a second level glass pavilion lunchroom and outdoor wood deck terrace. The exterior envelope and interior elements have been designed to echo the prairie lines, and to operate as an extension of the landscape.
