New York / Weiss/Manfredi

Diana Center

Sometimes, architectural complexity comes in a simple form, even a box. The Diana Center, designed by New York–based Weiss/Manfredi for Barnard College, looks simple: a five-story glass prism served straight-up. Its terra-cotta color matches the largely brick Barnard and Columbia University campuses, which face each other across Broadway.

A closer reading, however, reveals a narrative of complexity. The façade is paneled in glass, but not in a display of transparency for transparency’s sake: Some panels have a graduated frit; others are shadow boxes, with space between a translucent glass outer layer and a second opaque inner layer. The functions inside the building establish whether the panels will be opaque, transparent, or something in between. A swath of transparent glass rises diagonally up the Broadway façade, revealing a stepped, four-story atrium full of activity.

In 2003, the architects won an invited competition to design the building as a student center, with classrooms and studios devoted to art, art history, architecture, and theater. The college wanted a mixed-use building whose circulation and adjacencies would help catalyze interaction between students, faculty, and the various disciplines.

Toolbox

The highly varied curtain wall of the Diana Center illustrates one tenet of chaos theory: Simple systems can breed complexity. There are only three types of modular glass panels in the building’s curtain wall, even though the complexity of the patterns defies easy recognition.

One type is the shadow box, which is composed of two layers: a color-integral glass panel in front and a metal pan set 4 inches behind. The glass panel, provided by Goldray Industries, is acid-etched on its exterior surface to give a matte texture, and fritted with a terra-cotta color on the interior surface. The metal pan is painted bright red, with a coating from Linetec. The refraction of light through the glass and reflection off the metal pan produces a hazy, softly luminous effect that changes with the angle of the sun, and the colors inventively relate to the surrounding brick façades.

The second panel type is double-glazed and acid-etched in vertical striations graded from opaque to transparent. The fritting—designed to maximize daylighting—occurs on the facing interior surfaces of each glass pane in the double-glazed unit, so a small gap separates the lines. Hoppers are used with these panels to allow natural airflow into the building.

The third panel type is a clear, double-glazed unit, which is used primarily in public spaces, such as the fire stairs and atria.

The three panel types come in four sizes, which are combined to result in uniform 5-foot curtain-wall modules (2-foot panels pair with 3-foot panels, and 3-foot-9-inch panels pair with 1-foot-3-inch panels). The building’s 1,154 panels create shifting, but related, patterns determined by the functions of the spaces inside.

“The colors change depending how the light and its angle play with the etching,” says Weiss/Manfredi design partner Marion Weiss, “shifting from dull copper brown to copper red. The colors enter into a conversation with the traditional buildings. The idea is a building that changes over the course of a day.”

The architects—the firm’s full name is Weiss/Manfredi Architecture/Landscape/Urbanism—acted as their own consultants, applying their several disciplines simultaneously. They developed the site, landscape, and plans together as an integrated and complex whole.

The former building on the site, the McIntosh Center, was built in 1969, when institutions that were then allergic to the city walled themselves off self-protectively. The fortresslike building even divided the campus, with a front plaza and a daunting flight of stairs higher than Milbank Hall—the oldest structure on campus—next door.

Weiss/Manfredi’s design was urbanistically corrective. The glass façade, which meets the street, invites the urban gaze into the building. A front door along Broadway serves a café, as well as a black-box theater and an elegant, wood-paneled event oval, both on basement levels.

On the campus side of the building, the architects struck a sight line from the entrance of Milbank Hall across Lehman Lawn to the campus’ famous wrought-iron gate, resulting in a wedge-shaped plaza that sliced the seven-story prism into a wedge. The architects landscaped the plaza into grassed terraces stepping down gently from the lawn to the Milbank courtyard. They also invited the landscape up into the building: A terrace adjoining the lawn leads into the café, and then up the open tiers to the second-floor dining room, third-floor reading room, and fourth-floor gallery. The terraced spaces are all transparent to each other, and to views from the lawn. The building remains public all the way to the grassed roof (the architects are targeting LEED Silver certification).

The landscape and building are both sectional ladders of student life. The façades are always occupied. “The students own the building,” design partner Marion Weiss says.

The building that shifts vertically in section also shifts horizontally: Nowhere is the plan simply extruded. A wandering, glass-enclosed fire stair steps up the west façade, meandering in and out of the building’s floor plate, and the rooms expand and contract throughout the building according to programmatic necessity.

The architects have created a gesammtkunstwerk, a design addressing urbanism, architecture, landscape, and social life. And that design addresses both the big picture and the small: The hazy quality of the shadow box façade panels is echoed in translucent resin tabletops.

The building’s character is both urban and urbane. The scale is generous, and the sequence of spaces both civilized in its processional quality, and experiential in the way it unfolds. Above all, the building that replaced McIntosh Center did not do so by reiterating what design partner Michael A. Manfredi calls “the clichés of historicism—cornice lines, brick, trim.” The architects looked forward rather than back, and so set the best possible example for students exploring their own creativity.
