The GSB Building is an iconic corporate destination. Companies headquartered here enjoy a highly-educated workforce and customer base thanks to an enviable location 10 minutes outside of Center City. Now, with Keystone at the helm, great will become awesome. Renovations to the GSB’s infrastructure are underway, as well as cosmetic upgrades including an expanded, modernized main lobby.
