153,000 S.F. Build-to-Suit Corporate Headquarters

Warrenville, IL
Exelon Nuclear

The 153,000 square foot Cornerstone II facility located at Cantera in Warrenville, Illinois was constructed as a build-to-suit corporate headquarters for Exelon Nuclear.

McShane Construction completed this five-story facility that included an adjacent structured parking garage featuring Warrenville’s first heliport.

McShane also completed an enclosed pedestrian walkway connecting the Exelon building to Cornerstone I, an adjacent multi-tenant office facility to maximize the accessibility and availability of the development’s common tenant amenities.
