McShane Construction completed Cornerstone I at Cantera on a design/build basis in Warrenville, Illinois.
The five-story, 157,500 square foot multi-tenant office facility is situated on a 16-acre site with frontage on I-88 and Winfield and Ferry Roads, offering outstanding tollway visibility and corporate identity.
The attractively-designed articulated precast and reflective glass construction offers a high caliber corporate appearance to complement its access to Cantera’s array of outstanding amenities. Underground executive parking, a delicatessen and a fitness center are featured on the lower level. McShane also completed the adjacent Cornerstone II at Cantera as the corporate headquarters of Exelon Nuclear.
