50 First Street, Mixed-use skyscraper complex in South of Market, US
50 First Street is a mixed-use skyscraper in San Francisco's South of Market neighborhood containing both office and residential space. The tower spans 53 floors with a distinctive tapering profile and external diagonal bracing visible along its facade.
The building began development under various ownership before Oceanwide Holdings acquired the project in 2016. Construction paused in 2020 during the pandemic, leaving the structure incomplete rather than finished.
The structure incorporates public spaces and modern architectural elements, contributing to San Francisco's evolving urban landscape and vertical development pattern.
The location near Salesforce Transit Center makes it easy to reach by public transportation. A large public plaza at ground level provides space to walk around and view the structure from different angles.
The development was planned to become San Francisco's second-tallest building before construction halted in 2020. Visitors today see an unfinished structure that stands as a reminder of abandoned architectural plans.
