The building features generous ceiling heights, expansive floor plates, and 2000-amp,3-phase power to support heavy electrical loads and specialized equipment. It is fully sprinklered and designed for operational efficiency, with multiple loading areas andconvenient access points. The site offers over 390 on-site parking spaces, ample truck circulation, and excess land that may support expansion or reconfiguration. Itscampus-style setting delivers scale, functionality, and flexibility for manufacturing, technology, distribution, or institutional users.
