This
impressive, LEED-certified, fifty-six-story office tower is Philadelphia’s
newest and tallest. The Comcast Center’s stateliness and elegance are carried
through to OLIN’s plaza at its base. However, the plaza is more than merely a
suitable platform for the building—it is a vibrant, well-used, civic space,
wholly connected to the city. It serves as a new destination for residents and
workers, and as a principle entry to the regional rail lines, markets, and food
court located beneath the site. The plaza elements are conceived as a series of
vertical and horizontal layers. Along its most civic-facing edge, a sheared
aerial hedge defines the plaza and filters the noise and activity of bustling
John F. Kennedy Boulevard. On the plaza, a plinth supports a café servery
housed in a distinctive, illuminated glass box slipped beneath a sculptural
trellis of dichroic glass, steel, and vines. A dynamic fountain provides a
linear veil between the plinth and the main plaza. The plaza is paved in a
pattern of granite bands that reinforces the structural grid of the tower. To
connect the exterior to the interior both visually and physically, the paving
extends into the building’s winter garden.
