A $63-million effort has revitalized the 48-story, 1.2-million-sq-ft 101 California tower, which was built in 1982, with a reenvisioned outdoor plaza, lobbies and new tenant amenities. Other additions included security upgrades, stainless steel cladding and improved lighting. A tenant-only space allows for casual work, small team meetings or festive gatherings while offering views from a cantilevered skybox projecting into the seven-story main lobby atrium.

The project, completed under budget and ahead of schedule in June 2023, spanned 12 zones—five for the exterior plaza and seven for the interior lobbies—over 22 months. All work was completed while more than 70% of the building remained occupied, which required careful planning and coordination to minimize disruptions.
