Last month, Philadelphia YIMBY shared renderings of Broad and Lombard, a 553-foot-tall, 43-story development proposed at 500 South Broad Street (alternately 500-10 South Broad Street in Center City. Designed by SITIO Architecture + Urbanism and developed by Broad Lombard Associates LP, the project will consist of three buildings, with the new tower spanning 517,907 square feet and featuring 468 residential units, the renovated three-story Health Center Building with 80,440 square feet of commercial space and underground parking for 30 vehicles, and a renovated historic townhouse. Today YIMBY shares an extensive collection of new renderings for the project.
A project description provided with the Civic Design Review submission states the following:
Broad & Lombard is a Proposed Multi-Use Residential Tower Addition located at the southwest corner of Broad and Lombard Streets, along the Avenue of the Arts. The project site consists of 72,607 s.f. unity of use consolidation of 10 lots that encompasses the
Existing Health Center Building (Historic), the Existing Building (WCCS), and the Existing Townhouse (Historic). The site is zoned CMX4, Community Commercial Mixed-Use, the building is designed within the zoning requirements. The proposed Multi-Use Residential Tower Addition consists of an addition to the Existing Health Center Building totaling 517,907 g.s.f. The 43-story tower will house 468 apartments along with its support and amenity spaces, fronting Broad Street. The existing Health Center Building (historic) consists of 80,440 g.s.f. and consists of 3-story commercial/retail with 19,875 s.f underground parking for 30 vehicles and underground parking for 30 vehicles and 208 bicycles on site. An addition 20 parking spaces will be provided within 500 feet of the front entrance
The Proposed Multi-Use Residential Tower Addition provides entrances off Broad Street and Lombard Street. Both are connected to a
civic plaza that links both streets at the pedestrian level through the permeable lobby. The plaza area activates the urban corridor and
ties the streetscape to commercial space within the Existing Health Center fronting Broad Street. The transparent glassy base of the
Residential Tower Addition includes a social lobby space that is highlighted by a double-height feature stair connecting to amenities
on the second floor. This podium places focus on the urban corridor while providing breathing space for the historic Health Center to
the South. The mixed-use high-rise addition is designed to take cues from the Existing Health Center, and the north façade carries the
brick massing of the historic townhouses into the base of the building, reinterpreting the texture along the street and lobby. Sited on
a block rich in history, the building enhances its context, blending tenant amenities with commercial and public open space through
a series of finely-scaled terraces, decks, and plazas.
The cladding on the base’s two volumes contrast and complement each other, the west facing volume in masonry, the east volume
is clad in a glass curtainwall. The material palette is in-keeping with the quality of the materials found in the adjacent institutional
and residential buildings. Above the base the materials transition to an equally contrasting and complementary palette of metal and
glass. The glass consists of two types: the glass at the north side of the building is a clear to blue glass with a hint of reflectivity, the glass at the south end is a darker slightly grey glass which adds depth and weight to the contrasting volume.
The redevelopment of the site will result in the incorporation of several sustainable elements that will greatly enhance the quality and beauty of the surrounding environment. The impervious asphalt paving that now covers most of the site will be eliminated and
replaced with a combination of in ground landscaping and pervious paving, to manage stormwater and dramatically reduce the heat
island effect of current site conditions. The building will be developed to achive LEED 4.0 Gold certification. The project will provide
hundreds of residences in direct proximity to public transit while also providing car share, electric vehicles and bicycle parking on
site. This project’s unique location within the City’s major cultural corridor will continue to support and foster sustainable and healthy
lifestyles and urban vibrancy.
Although Philadelphia is teeming with new construction, new high-rise proposals are regrettably rare. As such, Broad and Lombard’s significant height and residential unit count, combined with a sleek design, central location, and adaptive reuse of historic structures, makes it arguably the most exciting new proposal in the city this year to date. We look forward to further development of the proposal and will share additional publications with further imagery and diagrams in the coming weeks.
