The Radian is a 500-bed residential and retail center at the edge of University of Pennsylvania’s rapidly expanding campus. The project was developed by a private developer in collaboration with the University which owns the land. The design integrates ground level retail, residential services, and open space into a hybrid building that not only serves its residents and the entire University population, but the broader West Philadelphia community as well.
Ground level retail pushes back from the street opening a public space for informal gathering. The residential entrance exists along this axis and public activity extends up and under the residential tower via a grand stair. This open court aligns with an adjacent quad on the south side of Walnut Street connecting to Locust Walk. Outdoor dining options are provided at the upper terrace level and allow for glimpses onto the street.
The ground floor lobby extends from the entry court through to Walnut Street with the resident mail room and study lounge located on Sansom Street to draw the residents through the building. The residents utilize the lobby as a thruway to help energize a long suffering street presence along Sansom Street.
The lobby geometries reflect the geometrical shift between the ground floor and residential tower above. The ceiling negotiates the complex structural shift and conceals the building systems that penetrate down through the lobby to the below grade utilities.
The building skin is a sustainable pre-fabricated rain screen wall panel system. The pre-fabrication allows for a tighter tolerance and higher construction and quality. Being manufactured off-site brings an economy to the project which could not be met with typical construction processes. The facade patterning responds to the varied size of the dwelling units and thus helps reduce the massing of the 14-story tower.
Functioning as a critical element to the success of the Walnut Street elevation is the inclusion of an elevated terrace supporting over 12,000 sf of green roof. The green roofs were located adjacent to the elevated terrace to maximize visibility of the system for the residents and visitors to the terrace restaurant, further elevating awareness of roof greening as a strategy to lessen the impact of the buildings on the environment.
The Radian neither belongs to the assortment of retail spaces of West Philadelphia nor to the flat academic buildings that are signature of University City. It gracefully blurs the line between these two opposing landscapes, while upgrading the atmosphere of both.
