Watch Studio Gang’s “Hive” installation rise at the National Building Museum

Hive, an exhibition by Studio Gang, will be this year's Summer Block Party installation at the National Building Museum. While it opens July 4, you can watch its progress from the comfort of home, courtesy a work zone cam on the Museum's website. Built entirely of more than 2,700 wound paper tubes, the installation features three interconnected, domed chambers that reach 60 feet in height and mimic insect hives. Its tallest dome features an oculus over ten feet in diameter; it will filter in light to create light and shadow patterns. The tubes, which are made out of sustainable material, have a reflective silver exterior and a magenta interior that contrasts sharply with the Museum’s historic 19th-century architecture and Corinthian columns. Hive's form is inspired by other iconic built structures, including Eero Saarinen’s Gateway Arch and Brunelleschi’s Dome at the Florence Cathedral in Italy, as well as natural forms like a spider web. The smaller chambers also feature tubular instruments ranging from simple drum-like tubes to chimes. The installation creates pockets of spaces within the vast Great Hall, allowing different programs to occur within each area. Its modification of sound, light, and scale aims to challenge the way humans interact with spaces and installation sculptures. Hive will go on display from July 4, 2017, to September 4, 2017.

Studio Gang will design enormous, acoustically-attuned domes for the National Building Museum

Studio Gang will install a human hive in the halls of the National Building Museum this summer. The Chicago- and New York–based studio will erect thousands of wound paper tubes to create three domed rooms, the tallest of which will stretch 60 feet into the air. The tubes, a sustainable building material, range in height from a few inches to ten feet. The installation, aptly named Hive, will anchor the D.C. museum's Summer Block Party, a series of temporary commissions inside its Great Hall. Previous participants include James Corner Field Operations (2016), Snarkitecture (2015), and BIG (2014). “When you enter the Great Hall you almost feel like you’re in an outside space because of the distance sound travels before it is reflected back and made audible,” said Studio Gang founding principal Jeanne Gang, in a prepared statement. “We’ve designed a series of chambers shaped by sound that are ideally suited for intimate conversations and gatherings as well as performances and acoustic experimentation. Using wound paper tubes, a common building material with unique sonic properties, and interlocking them to form a catenary dome, we create a hive for these activities, bringing people together to explore and engage the senses.” The firm's installation will compress the capacious Great Hall, with its imposing Corinthian columns, into intimate spaces for conversation, playing musical instruments, or cooperative building activities for children (and adults so inclined). The tubes also feature reflective silver exteriors and vivid magenta interiors, creating a spectacular visual contrast with the Museum’s historic nineteenth-century interior. Hive will be on view from July 4–September 4, 2017. Check nbm.org for more information about the exhibition and related programming.

Jeanne Gang is designing her first project in Canada, a mixed-use tower in Toronto’s Yonge + St. Clair

Chicago architect Jeanne Gang has been hired to design her first project in Canada, a residential tower in Toronto’s Yonge + St. Clair neighborhood, with retail space at street level.
The client is Slate Asset Management, which owns ten properties in the neighborhood and is working to rejuvenate it with public art, vibrant streetscapes, and first-rate design. Slate and Gang’s office, Studio Gang, announced this month that the residential tower will be at the southwest corner of Yonge Street and Delisle Avenue. The project is the latest in a series of high-profile commissions by Slate, including an eight-story mural by international street artist Phlegm. The tower will be Studio Gang’s first building in Canada, and it’s part an effort by Slate to reimagine Yonge + St. Clair. Known for her Aqua Tower in Chicago, one of the world’s tallest buildings by a woman-led design team, Gang received a MacArthur Foundation “genius” award in 2011. She has been named to receive an honorary fellowship from the Royal Architectural Institute of Canada in May. The ceremony will be part of the Institute’s Festival of Architecture in Ottawa from May 24 to 27, and Gang will give the festival’s keynote address. “Yonge + St. Clair is on its way back. Having occasion to bring Studio Gang’s first project in Toronto to the neighborhood signals to the rest of the city that we would like to create something special here,” said Brandon Donnelly, Vice President of Development at Slate Asset Management, in a statement.
“As our practice’s relationship with Canada grows, we’re excited to explore Toronto and to understand the unique DNA of the Yonge + St. Clair neighborhood,” said Gang. “We hope to design a building that will strengthen relationships within the neighborhood and the city.”According to the development team’s announcement, Studio Gang will work with Slate to organize a “public consultation” this spring to gather community input before making a design submission to the city. According to the developers, the final building will be primarily rental, with retail space at grade, in keeping with Slate’s long-term vision for the area. While the design for the building has not been finalized, Donnelly said, a couple of decisions have already been made.“It’s not going to be a typical all-glass tower,” he said, citing a need to introduce material variety into Toronto’s skyline. “We want to push boundaries in terms of sustainability and building efficiency, which means we are thinking carefully about the building envelope and its materials.” The Studio Gang commission will be the first ground-up tower in the area by Slate, which controls all four corners of the intersection of Yonge and St. Clair.The decision to commission Studio Gang was made after a selection process that emphasized design methodology, site context, and Slate’s aspirations for world-class architecture and a fresh vision.
Yonge + St. Clair is a transit-rich area with a subway and dedicated streetcar tracks, but it is also a short walk from some of the city’s most admired neighborhoods and a ravine system that offers direct access to quiet green space. The juxtaposition of natural and built environments is expected to serve as inspiration for the project. “There is a hill that crests at Yonge + St. Clair, which means the... site acts as both a pedestal and a view terminus from way uptown,” said Donnelly “The challenge will be to develop a building worthy of being showcased, but we feel confident that we have the right team in place to do just that.”

Studio Gang completes a second public boathouse along the Chicago River

As the first snow of the season fell, a large crowd gathered along a quiet bend in the South Branch of the Chicago River. Jovial groups of teens, community members, and public officials were all there for the opening of the Eleanor Boathouse at Park 571 in the South Side neighborhood of Bridgeport. The boathouse is the second designed by Studio Gang Architects and the final of four boathouses planned for the Chicago River.

The boathouses are part of a much larger movement within the city to connect the public with the underutilized river. Though the river is still heavily polluted—two half-sunken boats can be seen up river from the Eleanor Boathouse—the city is quickly improving its resources along the shore. The boathouses specifically provide space for rowing teams to train, kayaks to be rented, and people to directly access the water.

“The Eleanor Boathouse supports the larger movement of ecological and recreational revival of the Chicago River,” Chicago Mayor Rahm Emanuel said at the opening. “For too long, Chicago residents were cut off from an asset in our own backyard. So today, we are transforming our rivers from relics of our industrial past to anchors for our neighborhoods’ futures.”

Like Studio Gang’s earlier iteration, the Eleanor Boathouse takes its form from the rhythmic movements of rowers. Divided into two structures, undulating rooflines allow for clerestories, which bring soft light into the project. The lofty interior of the 13,171-square-foot boat storage structure can hold up to 75 boats for use by several rowing teams, clubs, and organizations. The other structure is a 5,832-square-foot field house that contains a multipurpose community room, main office, open seating area, restrooms, and showers, and can accommodate 57 “erg” machines, which simulate rowing movements for training purposes. A dark zinc facade wraps most of the project, while one face of the boat storage building is a custom green gradient window screen.

While Chicago’s winters can be brutal, the boathouse is already under heavy use. Rowing teams train in the river nearly year-round and there is also classroom and activity space for after-school and community programs. “This connects us to the origins of the city. The river is the first reason that the native peoples and eventually Fort Dearborn were settled here,” said Studio Gang’s Managing Principal Mark Schendel at the opening. “And it is that potential to come back to that amazing resource and put citizens back on the water. It is the type of project, as architects, we love to do.”

Jeanne Gang unveils new interiors for the American Museum of Natural History

This morning, architect Jeanne Gang of Chicago-based Studio Gang and exhibition designer Ralph Appelbaum unveiled their latest designs for the new Richard Gilder Center for Science, Education, and Innovation. Focusing on the museum's interior spaces, Gang and Appelbaum shared plans for the new Insectarium, Butterfly Vivarium, Invisible World's Immersive Theater, and newly revealed Collection Core. The 21,000-square-foot glass-walled Collection Core will form the heart of the center, housing 3.9 million specimens, or approximately 10 percent of the museum's specimen collection. It will feature observation areas so visitors can see scientists at work, storage spaces, rare collections, and other items previously not on view. "We started with what's already there," said Gang. "The Collection Core is located right there in the building, but no one can see it. By extending it and working with Ralph [Appelbaum] we could make it something people can experience and show more of the museum's content." In the Insectarium, the first museum gallery dedicated to insects in more than 50 years, and the new permanent Butterfly Vivarium, a combination of live species and interactive, high-tech exhibits will help educate the 5 million people who come through the museum each year. In addition to the new education facilities, which will include learning labs, classrooms, and age-specific zones, the 9.520-square-foot Invisible Worlds theater will recreate authentic science visualizations to illustrate organisms and processes that are too small, too fast, or too distant for humans to perceive in real life. Slated to open in 2020, the 235,000-square-foot center has generated a buzz with its organic, futuristic design, inspired by glaciers and canyons. To achieve this unusual design, Gang and her team created a model out of a block of ice. "It was a freezing winter and the software tool was too slow so we got this block of ice and poured hot water from a tea kettle into the block and that helped inspire the form," Gang said. "We've also been working with a lot of scientists and this became a way we could easily digitize and represent the design." Gang cites "flow" as a guiding principle for the overall renovation and addition. The Gilder Center will contribute to better wayfinding throughout the museum, which is notoriously difficult to navigate. Thirty new connections across the 10 existing buildings will enhance visitor experience and allow for the curators to offer better storytelling. "It's very much an "innie" building," Gang told AN. "It draws people into the exhibits, into the other buildings, and into the park itself." Additionally, the project is on track to receive LEED Gold with natural lighting and heat and water saving strategies. "The verticality of the space is the key sustainability feature because it's providing natural light deep into the museum and we can also use the verticality to create displacement ventilation so that the natural stack effect can occur," Gang said. Technology and flexibility were integral to the design with interactive media displays, micro cameras, and more. "Nothing here will be frozen in time," explained museum president Ellen V. Futter. "The design has the ability to constantly evolve in accordance with how we as people change the way we learn and encounter new information."

Studio Gang reveals images of new St. Louis tower

Chicago firm Studio Gang has released images of their new tower, "One Hundred" at 100 North Kingshighway Boulevard in St. Louis, Missouri. Backed by developer Mac Properties, the project is Jeanne Gang's first in the city and will look over Forest Park, rising above 350 feet. “In a climate with four distinct seasons, we wanted to make it possible for residents to enjoy the different views and natural changes in light over the course of the year,” said Gang, founding principal of Studio Gang in a press release. “By experimenting with the geometry of the facade and refining the apartment layouts, we were able to make every apartment into a corner unit perched above the park and city.” One Hundred's serrated and inwardly sloping facade (repeating every four floors) creates terracing, some of which will be shared among tenants. A green roof podium will be available on the sixth floor and further greenery will be used for the collecting and storing of rainwater. Meanwhile, other amenities include parking and an assortment of retail outlets at street level. “The Central West End is an extraordinary, architecturally rich neighborhood that has evolved over many decades,” said Eli Ungar, founder of Mac Properties. “In planning a development for this exceptional site, we selected Studio Gang for their commitment to thoughtful, sustainable development and to a design that both honors the history of a community and contributes to its continued evolution.” One Hundred is due to break ground next year, with completion pinned for 2019.

Studio Gang to design Arkansas Art Center expansion

The Arkansas Arts Center (AAC) has announced Chicago-based Studio Gang Architects as the design architect for its next building project. Studio Gang was selected from a field of five finalists that included Allied Works, Shigeru Ban, Thomas Phifer, and Snohetta. “Designing a re-envisioned Arkansas Arts Center is a truly exciting commission,” Studio Gang founder Jeanne Gang said in a press release. “Its extraordinary collection, historic MacArthur Park setting, and rich mix of programs present a unique opportunity to redefine how the arts can strengthen local communities and surrounding regions. We look forward to working closely with the AAC to discover how architecture can enhance the Center’s important civic and cultural mission by creating new connections between people and the arts in Little Rock and beyond.” More than just a renovation and expansion of the museum's current building, the project is expected to completely change the way the museum is used and interacts with the surrounding downtown. “This project is about more than just addressing the physical issues of the current building. It requires rethinking how the AAC fits into the downtown fabric,” said Todd Herman, executive director for the AAC. “How can we best serve the community, and how do the AAC and MacArthur Park connect to other social and cultural nodes in downtown Little Rock? We want to do more than build; we want to transform the cultural experience.” The AAC was founded in 1960 and has a permanent collection with a heavy emphasis on drawing, watercolors, and other works on paper. This includes works from Rembrandt, Picasso, and Degas. The museum also possesses the largest U.S. collection of drawings and watercolors of early 20th century French Neo-Impressionist painter Paul Signac. The next step in the $65-million project will be to select a local architect to collaborate on the project. According to the museum’s website, an RFQ will be issued this month for that position.

Facade tuning with Studio Gang

facadeplus_logo1
Brought to you with support from
The Campus North Residential Commons at the University of Chicago offers a model of student housing that provides living arrangements for all undergraduate years, organized around large social spaces called “housing hubs.” The 400,000 square-foot commons project is positioned at the edge of campus and provides a new portal bridging the academic community with the surrounding neighborhood of Hyde Park. The project aligns with the university's ongoing 20-year plan to create more on-campus housing for undergraduate students and was awarded to Studio Gang and Mortenson Construction, who worked collaboratively as a design-build partnership, after an intensive four-stage competition process. The facade of the building is expressive of its internal programming, which features a range of residential units radiating outward from three-story, 100-person, central common spaces that aim to foster interactions and exchanges between undergraduate students of all ages. Younger students are positioned closest to the hub, while older students enjoy apartment-like amenities on the ends of the building. The stacking of these spaces produces a dynamic compositional grid that is picked up within precast panel cladding geometry through a series of angular and curvilinear spline profiles. Todd Zima, Design Principal at Studio Gang, said an in-slab hydronic radiant heating and cooling system was chosen early in the project to maximize user comfort: "Our distinct mission was enhancing and improving the community of the student body that was going to live in the building, therefore enhancing their academic success. Comfort was a huge element of that, which led to this radiant system." The system relied on an air tight construction assembly, which the team achieved through a continuous 3-inch thick spray foam moisture barrier cladding applied outboard of the structural slab.

Solution; Shuco UCC65 by Contractor Glazier Inc; Moisture Barrier: icynene md-c-200tm spray on insulation
The facade materiality grew out of an analysis of the University of Chicago's Neo-Gothic architectural context which incorporates thick limestone carved ornate facades. Precast concrete was chosen for its aesthetic qualities, and ability to be replicated through the use of molds. Over 1,000 precast panel shapes were installed on the facade, and were optimized for manufacturing to be highly repetitive. The architects say over 80% of the building features panel shapes that were replicated from the same formwork. The other 20% included unique shapes custom fit to unique conditions near ground level and around corners. Emily Licht, a Design Team Member at Studio Gang, led the facade development team. She developed a “facade tuning tool,” using Excel to evaluate complex formulas comparing the relationship of openings to room sizes. Beginning with a Passive House standard of 60-percent solid to 40-percent open, openings in the facade were adjusted to balance user comfort, light, and ventilation code requirements while managing solar gain based on orientation to ensure the radiant system would perform optimally. Licht said data, size, and exposure would go into the tool, and information about shading would come out: "The tool was very effective in showing how solar heat gain could be reacted to by the specifics of the facade." Zima described this optimization process as a "make or break" design problem where the failure of the performance of the facade would lead to a failure in the performance of the heating and cooling system. Natural ventilation was achieved through in-swinging windows to allow the full area of the opening to provide ventilation into the room. These operable windows are demarcated on the facade by a custom patterned metal panel which doubly functions as a solar shading device and guard for fall protection. The architects worked with an environmental engineer to calculate the different needs for each room and used custom patterning of the grills and frit glazing to diminish the solar heat gain. To integrate the use of these operable windows with a broader agenda of reducing energy reduction, the architects integrated hundreds of sensors at pre-planned points in coordination with a software and communications group on campus who are working to produce a visual interface that displays real-time data on energy usage. This system will provide instant feedback for students using the building to understand how their activities impact energy use. Weather monitoring systems on campus provide notifications to house leaders appropriate days for a natural ventilation mode, who then are able to make adjustments to the building's radiant heating and cooling system. An early facade panel mockup looked at coloration and finish of the precast material, while a full-scale mock-up looked at systems integrations with the building envelope. Licht said in addition to providing a look at the full facade system detailing, the mock-up allowed all of the trades to practice assembly of the building components: “It was an amazing experiment in everyone getting in on the process together and seeing how they would work during construction." The mockup compiled the most unique conditions of the project into one mashup of the building, involving a diagonal portion of the facade, a straight portion of the facade, a horizontal lintel, curtainwall, vented operable window, and more. Zima said the mockup was "intended to be a training device, but served all purposes of the project from client review to sub-contractor coordination for an 'assembly line' style design-build construction process." A circular groove located in the middle of a plaza created by the residential buildings received bench-sized sculptural pieces of concrete that originally acted as cradles for the shipment of precast units to the site. Zima refers to this as a nice "residue" of the construction activity. Zima concludes, "We're very proud that the facade—in many ways—tells the story of this project and what it is accomplishing.” He said this project represents the university's desire to change their relationship with the neighborhood, evolving from a cloistered typology that traditionally separated the “purity” of academics from the “grittiness” of the city. "What our project does most successfully is that it makes a main entry point a place to gather before passing through into a new version of the University of Chicago.”

AN Exclusive: Studio Gang beats out Michael Maltzan and Allied Works to design unified California College of the Arts campus

Chicago-based Studio Gang Architects (SGA) has been selected to design an expansion of the California College of the Arts (CCA) campus in San Francisco, beating out Michael Maltzan Architects and Allied Works for the prestigious commission. Over the next five years, CCA will work with SGA to develop a design for a comprehensive expansion of the existing arts campus to provide educational facilities for the college’s 2,000 students, 600 faculty members, 250 staff members, and 34 academic programs in San Francisco’s Mission Bay neighborhood. The expansion, outlined in the school’s Framing the Future visioning plan developed by Gensler and MKThink in 2015, will aim to absorb the school’s Oakland satellite campus as well as create on-site housing opportunities for students on a site adjacent to the existing San Francisco campus. In a press release announcing SGA’s selection, CCA Board Chair C. Diane Christensen commended the firm’s long list of ground-breaking educational projects, saying, “The selection process was extremely thorough, involving intense review and significant input from many constituencies. Studio Gang’s visionary work, commitment to innovation and sustainability, and collaborative work style makes the firm an excellent fit for this project and for CCA. Jeanne Gang leads an extraordinary team that is very familiar with San Francisco and our still-emerging neighborhood at the intersection of the city’s innovation corridor, the new DoReMi arts district, and Mission Bay. We are thrilled with the prospect of working with Studio Gang and have high hopes that our new campus will help redefine 21st-century arts education.” Studio Gang CCA Unified Campus from Architect's Newspaper on Vimeo. In the same press release, Jeanne Gang, founding principal at SGA, focused on intrinsic potential for the project to yield innovative educational synergies, remarking, “We are excited to discover with CCA the possibilities that a unified campus in San Francisco presents for the future of art teaching, learning, and making,” adding, “The site has enormous potential to build an expanded, increasingly connected campus for CCA in a newly thriving design district. We are looking forward to a creative and engaged design process to help CCA continue to change the world through dynamic arts education.”

Studio Gang’s research-based approach to ecological design rethinks the shape of urban waterfronts

As Studio Gang gains respect as an office that builds formally and programmatically ambitious projects, one aspect in particular has helped the firm continue to be a major force: It is an office that does its homework. Every project that the studio does is accompanied by a body of research as well as collaborations with experts often outside of architecture. “As architects, we think of our role as being that of the translator,” explained Claire Cahan, design director at Studio Gang. “Early on in the project we bring in experts from interdisciplinary fields to discuss the past, present, and future conditions of a site. Our job is to ask questions and translate ideas between disciplines.” This becomes particularly visible in projects that involve water ecologies.

After a yearlong study in collaboration with the National Resources Defense Council (NRDC) and the Harvard Graduate School of Design (GSD), the studio released Reverse Effect (2011). The book explored urban and ecological implications of severing the link between the Chicago River and the Mississippi River, effectively reversing the flow of the Chicago River to its original direction (something that has actually happened three times). The book presented a new Chicago that embraced a reshaped river as part of its cultural and civic space.

“We’re interested in the intersection between built and natural environments,” said Cahan about the office’s broader vision and approach. “While building projects typically have distinct property lines and boundaries, natural systems often intersect with property lines in a fluid way. Through research, which includes conversation, mapping, and analysis, we seek to understand the natural, cultural, economic conditions far beyond a property line.”

A similar study, in collaboration with Milwaukee-based Applied Ecological Services and Edgewater Resources, looked at the 1,000-acre Milwaukee harbor. The Edge Effect master plan set out to establish a framework and logic for Milwaukee’s waterfront development. The master plan envisions relocating the current active inner harbor to a new outer harbor, while bringing the city to the water’s edge. The process would include softening the coastline to achieve a more complete and sustainable ecosystem by learning from stable natural coastlines and reefs. This concept is already being deployed in the Studio Gang–designed improvements to Chicago’s Northerly Island, which has a similar geographic situation.

Studio Gang fuses storage and display in their design for a traveling photography exhibition

Studio Gang Architects, working with art advocate Project&, have produced a traveling photography exhibition that highlights the stories and photographs of 24 American workers. Studio Gang produced 18 modular display cases which double as the show’s shipping containers. The show, entitled Working in America, features the work of Pulitzer-Prize winning photographer Lynsey Addario. The opening of the show corresponds with the anniversary of Studs Terkel’s 1974 book Working, which explored similar themes. The show consists of stories and images from across the country. Studio Gang’s design features seven-foot-tall display cases that can be locked together in sets of three. These cases were developed for ease of transportation and the ability to show in difficult situations. This was important as the show will be traveling through the United States on display at public libraries. Exhibiting in libraries presents a special challenge, in that work can be displayed on the walls. “I envisioned self-crating steamer trunks that held an entire world inside, and when opened, revealed the large-scale photographs and the working lives of Americans, putting their voices and narratives at the center,” explained Jane M. Saks, the show's curator. “The team from Studio Gang not only turned that vision into a reality, but they designed the displays so that they lock together and literally hold each other up. The design is elegant and almost poetic in the way it speaks to our interdependence as workers and human beings, and the strength of all of us when we join together.” The cases are built of Baltic Birch plywood and vegetable-tanned leather for the handles. “We wanted to give visual space and dignity to each of the individuals represented in the photographs,” said Jeanne Gang. Studio Gang’s experience with exhibition design includes shows for the Art Institute of Chicago, Art Basel Miami, and the Chicago Architecture Biennial. Working in America is currently on display at Chicago’s Harold Washington Library Center, and will run through the end of January.

Studio Gang and OMA among architects competing to redesign Tour Montparnasse in Paris

A list of seven firms (three French and four international) have been selected by the Ensemble Immobilier Tour Maine-Montparnasse (EITMM) as part of the second round of a competition to redesign the much-maligned Montparnasse Tower in Paris. Built in 1973, the 690-foot (59 story) high-rise has been the regular subject of scorn from Parisians and architects alike. Now Dutch studio OMA; British practice, PLP; French architect Dominique Perrault, and Chicago firm Studio Gang among others are in the running to take on the tower's redesign. Known as the Tour Montparnasse, the building changed city planning policy after its completion 33 years ago. Buildings in the French capital were banned from rising above seven stories two years after it was constructed, a policy that has allowed the skyscraper to remain as Paris's tallest building. The full list of firms vying to re-imagine the tower can be found below: The list of seven came from a list of more than 700 firms that entered the first phase of EITMM's competition. In a press release, one stakeholder said the seven agencies were selected for their "reliability, expertise, audacity and their understanding of the challenges we face." Now the competition has briefed the chosen seven with submitting a proposal that will supply a "powerful, innovative, dynamic and ambitious new identity to the famous Parisian landmark, whilst integrating the challenges of usage, comfort and energy performance to the highest levels." These proposals are due in March 2017. The competition's third stage will see this list whittled down to two finalists from which a winner will be announced in July next year. The project is due to cost $326 million with one-third of this being privately financed by Tour Montparnasse's co-owners. Construction is set to start in 2019, being completed by 2023. Jean-Louis Missika, deputy to the Mayor of Paris, in charge of urban planning, architecture and economic development for the Greater Paris project, said: "We are delighted with this varied and audacious selection of architects which promises a great diversity of ideas, approaches, and innovations for the transformation of the Montparnasse Tower, the initial stage in the renovation of the whole area."
