300 Lakeside
TMG acquired a full city block in Oakland featuring a 28-story office tower, a low-rise mixed-use building, and a 1,300-stall parking garage topped by a 2.3-acre rooftop garden.

TMG acquired a full City block in Oakland that includes the 28-story 300 Lakeside office tower, a low-rise mixed-use building originally constructed as a department store, and a 1,300-stall parking garage that is topped by a spectacular 2.3 acre rooftop garden, likely the first green roof built in North America.
With many of the tower tenant leases due to expire shortly after TMG’s acquisition, TMG pre-leased the entire 910,000 square foot tower to PG&E for a headquarters relocation from San Francisco- the single largest new office lease executed in the nation during 2020. TMG designed and constructed a comprehensive overhaul of the tower consisting of a voluntary seismic retrofit that included construction in spaces occupied by other tenants, upgrades of other key building systems, and tenant improvements on 21 stories of the tower spread out over 7 phases, each approximately 90,000 square feet. The entire project was fast tracked to meet PG&E’s occupancy targets. At it’s peak, construction involved three shifts working 24 hours a day. Despite COVID-induced supply chain disruptions, the design, permitting and phased construction of all building improvements were completed in just 28 months. TMG also performed a seismic retrofit of the garage as well as installation of car chargers, life safety and security enhancements.
The project financing structure included both a bridge loan and C-PACE bonds. At the time of bond issuance, it was the largest ever C-PACE financing backed by an office building. PG&E elected to acquire the property from TMG Partners and closed on the purchase in 2025.
