445 Bush Street

A pre-fire Telephone Company building by A.A. Cantin, who would later  collaborate with Miller and Pflueger on the famous New Montgomery Street Telephone Building in 1925 [140 New Montgomery]. This building was relatively unharmed by the earthquake and fire of 1906 due to extensive fireproofing including a concrete clad steel skeleton and rolling steel shutters over wire glass in metal frames. The handsome brick and terra cotta design on the front fa├žade is in a three part composition with Renaissance ornamentation.

Original, renovated elevator cabs take Tenants to full floor, creative, spaces complete with exposed concrete floors, high ceilings, and operable windows. The building is fully secured with keycard access and a lobby guard on-site during normal business hours. Fiber connectivity and dedicated lower level storage available to all Tenants. Bike friendly.
