Citizens Bank Park was constructed just east of the site of Veterans Stadium on the north side of Pattison Avenue between 11th and Darien Streets in South Philadelphia and spans a 21-acre site. The ballpark structure is situated uniformly within the city street grid.

The structure of the ballpark is formed by multi-story buildings containing fan facilities, team offices and services that surround the grandstand bowl and face 11th Street on the west, Pattison Avenue on the south and Darien Street on the east. On the north, lower scaled buildings parallel Hartranft Street and create an open-air concourse. At the four corners of the site, landscaped entrance plazas open the park to the street. Each of these entrance plazas have a distinct character and focus, echoing the City of Philadelphia design plan with its four unique squares.

The ballpark's exterior design combines the essence of Philadelphia's rich tradition of sports architecture with an unmistakably modern 21st century style. As it faces the street, the ballpark is clad in brick and stone. Arcades on the south and west provide shadow and shelter. Parallel to home plate, third base and first base, glass enclosed 50-foot high lanterns glow at night. Approaching the corner plazas, the steel framed seating bowl and lanterns flank the primary entrances. The street-level entrances lead directly to the airy main concourse and an open view to the playing field.

With the Philadelphia city skyline as the backdrop, the new ballpark features "bowl-style" seating with the playing field scooped out 23 feet below street level. The seating bowl layout is inspired by the classic plans of the Baker Bowl, home of the Phillies until 1938 and Connie Mack Stadium (formerly Shibe Park), which housed the team until 1971 when they moved into Veterans Stadium. Like Connie Mack Stadium, the upper and lower decks do not correspond exactly in plan. The cantilevered steel structure of the park allows for more open seating areas.

The cross section of the ballpark is configured to place fans on top of the action. Less than one-third of the seats are in the upper deck. To allow for a view of the downtown skyline, the field is oriented with home plate to the south and the outfield to the north, 45 degrees counter-clockwise from Veterans Stadium's orientation.

The facility features numerous amenities including family entertainment areas, open concourse concessions, and accommodations to provide for comfortable accessibility for the handicapped.
