Sony Entertainment

Headquarters New York, NY When Sony acquired the celebrated AT&T building in 1993, it commissioned Gwathmey Siegel Kaufman to transform the structure into the world headquarters of its music entertainment division and motion picture group. Certain modifications were inevitable: to begin with, the 1,000,000-square-foot, 35-story building, which had accommodated just 600 people when it was occupied by AT&T, would now have to house 1,600. Continue Back
Other changes were more unexpected. Gwathmey Siegel Kaufman redefined the Sony Atrium and Public Plaza as an accessible enclave of activity with a strong presence on Madison Avenue. Enclosing the soaring, 60-foot-high arcades flanking the north and south sides of the original building with aluminum-framed bay windows recast the previously open spaces as two entertainment retail stores. The special interior features of the retail spaces incorporate superscale images and exhibition, media, and display systems, as well as banners, flags, neon lights, and music.

The former annex building contains a series of new spaces, including a newsstand, commissary, ticket booth and the Sony Wonder Museum. Organized around theatrical motifs, the museum is an interactive, state-of-the-art attraction featuring electronic display signs and graphics meant to enhance visitors’ understanding of communication through technology.

In the ground-floor lobby, sheets of dramatic black glass have been inserted into arched recesses to offset the original granite walls and Lutyens-patterned inlaid marble floor. Black glass paired with anegre veneer recurs at significant points throughout the 35 floors. Color-coded elevator lobbies clearly express each Sony division—yet materials, colors and interior detailing provide a cohesive visual impression. The original perforated metal pan ceiling detail installed by Philip Johnson and the basic core organization were retained. What is new is a rigorous architectural approach to layering the space, both vertically and in plan, as well as in the custom-designed workstations and reception desks.

University of Cincinnati

Tangeman University Center Cincinnati, OH The Tangeman University Center is a key component of a major initiative to redevelop the University of Cincinnati’s campus core. As the centerpiece of the revitalized central campus, the rehabilitated student center manifests the University’s expressed commitment to design excellence as a means of enriching the educational experience, increasing enrollment, and improving overall competitiveness. Continue Back
The transformation and expansion of the center, a 1935 neo-Georgian campus landmark, significantly expands and updates the students’ facilities. The center now provides student lounges, a food court and dining area, a movie theater, an expanded campus bookstore, a multi-purpose great hall, meeting rooms, a game room, a café, a restaurant and the central campus kitchen. The renovation preserves several of the landmark’s historic elements including the façade facing the central commons, the original shed roof and its distinctive cupola. Its expansion was accomplished by wrapping the building in a circular form, which mediates disparate context and topography, and by replacing a previous addition with a new, more efficient structure. The primary organizing element is a new, three-story skylit atrium, a dramatic space where students can see and be seen. The center’s circulation core is an open stairway rising in the middle of the atrium, which was created by cutting through the building’s floors and stripping the central area to its structural elements. Glazing replaces much of the original gabled roof, flooding the atrium with natural light and exposing the original cupola above. The upper floor houses a conference center with flexible meeting spaces arranged around the new atrium. Beneath the new skylight at the quadrangle level of the atrium, an open lounge provides a place for informal meetings and performances. Additionally, this level offers computer stations where students can work in an informal social setting. On the Main Street level, a student dining lounge adjoining a food court features a two-story glazed wall overlooking the stadium. The dining facility surrounds a 200-seat theater, which occupies the bottom of the atrium with direct access off the new Main Street pedestrian promenade. The lower level of the student center houses a game room and provides access to the newly created Stadium Plaza. The new south wing houses the relocated campus bookstore, a restaurant, the central campus kitchen, and a new multi-purpose great hall accommodating up to 1,000 people for various events.

University of Washington

Henry Art Gallery Seattle, WA The contextual challenges posed by the renovation of and addition to the Henry Art Gallery not only afforded the opportunity to recast the 1926 Carl F. Gould building, a 10,000 square foot, two-story masonry structure, as the primary element of the west campus entry to the University of Washington, but in fact propelled the design and helped to define the program. Continue Back
Initially intended to be the north wing of a large, symmetrical arts complex that was never realized, the “old” Henry now contains the permanent collection galleries, Reed Study Center and curatorial offices. Gwathmey Siegel Kaufman’s three-story addition offsets the original structure with textured stainless steel, cast-in-place concrete and cast-stone. It houses flexible, top-lighted galleries, administrative offices and loading, storage and conservation spaces, as well as a new lobby, museum store and lecture theater.

But perhaps most important, the intervention visually separates the museum and addition from adjacent structures, affording a legitimate transition, a new sense of place, an expectant and enriched entry sequence and an integration of site, circulation and context.

In counterpoint to the original Henry, the new main gallery constitutes a memorable form to be re-experienced from within. The addition also acts as a carving away of a solid, revealing fragments that interact with the original Henry to re-site it as the asymmetrical—though primary—object in a new contextual frame, unifying the multiple architectural and site issues at the end of Campus Parkway.

Finally, the intervention is an architectural collage that unifies disparate elements in both contrapuntal and asymmetrical variations. The variations reestablish the primary site axis to Suzzallo Library, reconcile the vertical transition from the street to the plaza level and integrate the original Henry facade both with the new sculpture court and gallery entry and with the campus entry. As fragments, the forms imply but do not directly reveal their spaces. Thus anticipation, sequential revelation and memory become as crucial to the experience as the physical manifestation of the complex.

“In addition to establishing a positive and cooperative working relationship, Charles Gwathmey and the design team brought extensive design talents to the table. Their solution to the complex problem handed to them was original and bold. The team took what most considered to be a liability, an existing pedestrian bridge in an unfortunate relationship with the museum, and turned it into the hinge point of the entire design.”

Richard Andrews, Director

“[The] inversion of the expected order—descending to the largest, brightest, and most dramatic volume in the building— is the most compelling aspect of the design. To find this generously daylit and high-ceilinged space in the deepest reaches of the project is a revelation. Gwathmey’s dictum that one should experience a museum as a sequence of varied spaces, a kind of unfolding and revealing of artworks with a continuous sense of surprise, has been executed brilliantly.”

Justin Henderson in “Museum Architecture”, 1998

Apartment 40/41

New York, NY The apartment, designed within a 5,000-square-foot penthouse duplex space on the 40th floor set back from Central Park West, affords unique panoramic views of the New York City skyline and beyond. Continue Back
The owner, with a family of 7, specified a dense program, providing us with an opportunity to investigate and reinvent unique design elements throughout the space. One of the primary design strategies is the relationship between the dining and library spaces around the double height living room, compositionally integrating the staircase, cantilevered piano off of the balcony, the art wall wine display, the glass and gunmetal wall and railings. In addition, the moving bookcase between the library and study, allows natural light to the powder room while providing desired privacy to the study. From the master steam shower one can see through the electromagnetic glass, across the apartment to Central Park.

The material palette establishes a consistency throughout, while maintaining the formal parti and compositionally rich sculptural intervention, simultaneously rendering the space as a serene, private oasis separate from, but visually engaged in the city.

Apartment 51/52 West

New York, NY The design of this 8400 square foot duplex apartment on the 51st and 52nd floor of the Bloomberg Building on the east side of Manhattan required major floor removal and curtain wall structural reinforcement to accomplish the spatial and programmatic requirements. Continue Back
The mandate was to accommodate a family with four children’s bedrooms and sitting room, two working offices, master bedroom suite, living/dining, gallery space, kitchen/breakfast space with connecting sitting room, with both a sense of privacy and loft-like volumetric expansiveness, while simultaneously allowing the installation of a major modern art collection.The goal, through both the material palette of white Venetian integral plaster, stainless steel, maple floor, and white lacquer cabinets and the sculptural spatial articulation would both engage and counterpoint the spectacular 360° panoramic views of the city and beyond with a sense of serenity within a unique oasis environment.

Arango Apartment

New York, NY The parti for this apartment was anchored by the opening of what became the dining/sitting space into a balcony overviewing the living room, six feet below. This transformation created a volumetrically complex, open public room where, previously, there had been a sequence of small-scale, cellular spaces. Continue Back
This public room, comprising entry gallery, dining/sitting, and living, is modulated by a new black slate stair, dark-gray lacquer cabinets, and a single round column. These elements, along with the art, all act as primary objects within the oak-paneled frame.

The perimeter wall, which reinforces perceptual unity throughout the apartment, is deeply recessed, with articulated oak columns integrating the black slate sills and the dropped heads with stepped capitals. The design reaffirms the possibility of a dialogue between abstraction and traditional architectural language.

Fifth Avenue Apartment

New York, NY With one window facing Fifth Avenue and the remainder of the space oriented north to buildings across the street, the apartment is divided into two defined zones, living and service, that are connected by a link that could not be enlarged. Continue Back
In addition to a living/dining space, eat in kitchen, master bedroom suite and a private guest room, the program stipulated separate studies for the writer couple, storage for an extensive book collection and exhibition space for an important African sculpture collection.The parti was similar to Whig Hall at Princeton in that the existing frame was modulated by the intervention of a complex new object that accommodates both studies as well as the master bathroom and dressing room, while articulating the dining, living, gallery and book storage spaces. The kitchen and guest bedroom occupy the service zone. The use of glass block, oak, cabinetwork, interior clerestory windows, and slidding mirror pocket-doors, reinforce the transformation of a horizontal, cellular interior into a complex, dual scaled pavilion that serves as a house, office and gallery.
