The Stacks at 3 Crossings

The Stacks at 3 Crossings, the adaptive reuse of an industrial warehouse into a mixed-use development, demonstrates the practicality and sustainability of repurposing rather than
demolishing buildings in rapidly changing urban areas.

The project’s main inspiration was the neighborhood—Pittsburgh’s Strip District—and its history as an industrial nexus. Originally slated for demolition, a three-bay warehouse on the site provided an ideal opportunity for reuse. The structure’s simplicity is celebrated by keeping the foundation and outer bays intact and preserving the eight-foot-tall steel roof trusses, resulting in a nearly 40% reduction in embodied carbon. The outer bays are transformed into two buildings designed for mixed-use. The deleted middle bay is re-imagined as an outdoor courtyard that serves the buildings’ occupants and the larger community. This process of creative reimagining and rigorous recycling maintains the authenticity of place while creating higher overall value than new construction affords.
