Trinity Parking Garage San Francisco

Trinity Parking Garage is an iconic architectural landmark in the heart of San Francisco's vibrant SoMa district. Designed by renowned architect James A. Stewart, it was completed in 1972 and quickly became a symbol of urban renewal and architectural innovation.

The garage's most striking feature is its unusual triangular shape, which earned it the affectionate nickname "the wedge." This shape was dictated by the site's narrow and irregularly shaped lot, bounded by 3rd Street, Howard Street, and Trinity Place.

Stewart's design ingeniously utilized the site's constraints to create a unique and functional structure. The wedge-shaped form allowed for a maximum number of parking stalls within the limited space, while also providing ample natural light and ventilation through its sloping roof and open corners.

The garage's exterior is characterized by its ribbed concrete panels, which give it a distinctive industrial aesthetic. These panels were precast and assembled on-site, a construction method that was innovative at the time and helped to reduce costs.

Inside, the garage's layout is characterized by its efficient use of space and its focus on natural light. The sloping roof allows for taller clearance on the upper levels, while the open corners provide cross-ventilation to minimize the accumulation of fumes.

Over the years, Trinity Parking Garage has undergone several renovations to maintain its functionality and aesthetic appeal. In 1994, the garage was designated a San Francisco Landmark, recognizing its architectural significance and its contribution to the city's urban fabric.

Today, Trinity Parking Garage continues to serve as a vibrant public space. It is a popular parking destination for tourists and locals alike, and its iconic form remains a distinctive feature of San Francisco's architectural landscape.
