The new $700 million expansion to Philadelphia’s Pennsylvania Convention Center brings the total size of the center to one million square feet. I was selected to photograph the new spaces for the two construction companies, the architect and the owner.

My photographs of the exterior are here.

The soaring atrium on Broad Street has a ceiling ten stories high.

During two days when the Center was unoccupied, I photographed the spacious interiors with three assistants and a client representative.
