1100 Architect combines an 1851 cottage with a modern research center on University of Pennsylvania’s campus
In 1865, “hat and cap merchant” Robert D. Work purchased a Gothic Revival cottage at 3803 Locust Walk in West Philadelphia, riding the wave of the migration to the suburbs. This cottage, designed by prolific architect and author Samuel Sloan, was built in 1851. It now forms part of the Perry World House—a new destination on the University of Pennsylvania’s campus courtesy of New York studio 1100 Architect.
Work’s cottage 165 years ago featured fake limestone—stucco scored to look like a French stone chateau in suburban Philadelphia. Today, the new structure, which officially opened September 20, employs a closed facade featuring real limestone blocks hanging from a steel, barn-like perimeter cage.
“The project presented the challenge of putting history adjacent to modernity in the most blunt and direct way,” said cofounder of 1100 Architect David Piscuskas. Though limestone carries connotations of weight, the facade respectfully resists falling flush to the cottage’s shingles, following this sight-line down the rest of the front elevation.
In addition, a cage structure facilitates a more or less column-free interior. This provided freedom when mapping out areas of circulation and spaces for interactivity. (The building has a capacity of 554.)
“Any structural columns that are there are hidden very well,” said Piscuskas, the soon-to-be AIA president of the New York chapter. Despite the closed facade, the building maintains a sense of transparency from both outside and within. “The way that you move through this building is celebrated and is on view at all times,” Piscuskas added. From the outside, wide, metal-framed oriel windows facing the street allow passerby to see inside: Bridges, staircases, and open social spaces are all on display.
Elements of the original structure can be found inside, too. An original wall from the cottage is near the foyer. On the second floor, a meeting room translates the language of the facade as an extrusion through the space. A pitched ceiling creates a sense of verticality resulting from combining the cottage’s original second floor and attic and restructuring the roof.
On South 38th Street, the Wharton School’s imposing building once jarred with the quaint stylings of this 19th-century cottage six lanes of traffic away. Now, its impact is less severe, thanks to the new massing that still manages to mirror and echo the former suburban vernacular. Made up almost entirely of glass fenestration, the double-height venue gets a generous dose of daylight, making it an attractive place to meet. The roof comprises a series of pitches, all varying in height, which creates a contemporary expression of the original gables.
Form was also guided by inconveniences, such as a manhole encroaching on the building’s footprint. “We saw this as an opportunity to have more fun,” said Piscuskas, who described how a chunk carved from a corner was a workaround that aligned with the rest of the building’s similar geometry. The site’s topography, too, falls in line with the angular aesthetic as open space in the rear slopes down to the street.
Multiple layers of glass combine with corrugated metal panels to balance visibility and privacy in the University of Pennsylvania's new research center.As an experiment in interdisciplinary research, the Krishna P. Singh Center for Nanotechnology at the University of Pennsylvania is not a typical science center. It follows, then, that the university would not want a typical laboratory building, with a central corridor and minimal public space. Instead, the University of Pennsylvania asked Weiss/Manfredi to design the Singh Center around two principles. First, the building should create a new campus green for the school of engineering and applied sciences, in keeping with both the university’s and the city’s tradition of building around open quads. Second, the building should maximize natural light and visibility without compromising the integrity of the research itself. The most outstanding feature of Weiss/Manfredi’s design is the multi-layered glass curtain wall on the Walnut Street side of the building, which was designed with facade consultant Heintges and installed by National Glass & Metal Company. The outermost layer of glass, Guardian SunGuard AG 50 low-E on UltraWhite, which separates the building’s public spaces from the courtyard, achieves transparency while minimizing solar heat gain (the building is on track to achieve LEED Gold certification). It comprises an exterior etched panel by Walker Glass Co. wedded to a reflective panel with interior frit by JE Berkowitz. The etching and frit pattern varies from one part of the building to the next, for a total of five glass pattern modules. “The idea with that pattern was that where views out are most important, it’s most transparent,” said Weiss/Manfredi senior project architect Mike Harshman. “Where it’s more an issue of daylight, it’s more opaque.” The second layer of glass divides the Singh Center’s public spaces from its laboratory spaces. There, Weiss/Manfredi installed a laminated assembly with two layers of translucent frit. Again, the architects aimed for balance, this time between privacy and views out. Interior solar shades allow occupants to shut out daylight—or the eyes of passersby—when needed. On the first floor, an amber glass interlayer demarcates the research center’s 10,000-square-foot Bay/Chase Cleanroom. The color protects the interior of the cleanroom from ultraviolet rays and specific light wavelengths in the visible spectrum without walling it off completely. “Cleanrooms are typically a closed thing, but you can walk in and see everything going on in [there],” said Harshman. Glazed in interior fritted glass, write-up offices front the laboratories themselves, allowing light to enter the general labs. “We really saw the sections—the exterior glass, interior, and glass on [the] labs—as one assembly,” explained Harshman. The design allows daylight to penetrate deep into the building, while the combination of patterned glass and solar shades protects both the researchers and their experiments. The Singh Center facade is not all glass, however. Far from it. “From some views it looks like it’s very glassy, but the glass only represents one-third [of the building envelope],” said Harshman. “The rest is opaque and very insulated. The question became how to clad that surface.” Weiss/Manfredi explored a number of materials, including champagne-colored metal to echo the surrounding brick buildings. Ultimately the University of Pennsylvania chose silver anodized aluminum plate panels, explained Harshman, “because for them the context was technology.” The corrugated panels, which were fabricated and installed by Wyatt Incorporated with a custom finish by Spectrum Metal Finishing, were hung as a rain screen system over a prefabricated highly insulated exterior backup wall. “[There was] a great interest on Penn’s part that the project would have an aspect about scale and light. They liked the idea of the corrugated panels catching light at different times of the day,” said Harshman. The logic of the Singh Center facade culminates in the Forum, the multipurpose conference space that cantilevers over the courtyard. Its back and sides wrapped in protective metal, the Forum’s front wall is fritted glass overlooking the main campus. As a result, the place where researchers present their work is also the most connected to the university and the community around it. In the Singh Center, the University of Pennsylvania did not have to choose between openness and an effective research environment. They achieved both, with a building that turns traditional laboratory design on its head.
