Architect: DDG Location: New York, NY
Acting as design architect, developer, and general contractor, DDG developed a custom, cast-aluminum screen using 3-D modeling software and state-of-the-art hardware. A burlap texture was hand-applied to the set of 12 repeating components before the sand-cast molds were made and the finished components cast. The resulting sinewy surface creates dialogue with the cast iron historic buildings of the area.

The brother and sister architectural duo aiming to create the ultimate customizable, eco-friendly home
With a new project in the woods 30 miles outside of Helsinki, California and Finland–based brother and sister duo Ateljé Sotamaa is drawing on the longstanding tradition of shaping space outside the home through the home itself. The Atelier Houses are a planned community of 40 dwellings, but they are a far cry from beige clapboard subdivisions. Through digital fabrication and construction technology that leaves a light footprint on the land, the structures are infinitely customizable. Ateljé Sotamaa intends to create a new social space that is communal and ecological without sacrificing the comfort and conveniences of urban life.
The concept updates New Urbanism—a decades-old town plan based on walkable, green cities—with 21st-century technological optimism and individualistic zeal. Kivi Sotamaa, who cofounded the studio with his sister Tuuli, explained that the basic unit of an Atelier House is a single plank of wood. From there, clients can design almost infinitely customizable homes that draw on both the traditional Finnish fishing village and the camping lean-to, two typologies that embrace nature as a prerequisite of their functions.
“The house is radically open to the world around it,” Kivi said. “That’s a quality that comes with the design. Beyond that, each individual and each site is different, which will actually result in a community that’s quite nuanced and varied.” The Atelier Houses are single-family dwellings and two-story row houses that must have a large exposure to visually dispel the idea of home-as-fortress. Materials include local timber for visual unity and ecological soundness, as well as for an homage to the vernacular. The studio designed both the built-ins and the furniture, which residents have the option to customize.
Kivi worked with architect Greg Lynn, a professor and pioneer of mass customization, at the University of California, Los Angeles, but he takes Lynn’s ideas further. “I’m interested in whether you could use digital design and manufacturing tools that would come at the same price as a prefab house but with a strong architectural idea,” Sotamaa said. He would like to see the digital meld with the architectural more seamlessly; the houses are designed to facilitate this transition and anticipate future synergies. The assembly process is structured so that little machinery is needed on-site for construction and assembly, which cuts costs and reduces damage to the surrounding landscape. The community will be networked via fiber-optic cables to enhance connectivity to neighboring dwellings and the world outside.
The prototype home was completed in 2015, while construction on the first of the Atelier Houses is expected to begin this fall. Ateljé Sotamaa anticipates that developments in digital design and manufacturing will parallel hypercustomization trends in the music industry. “Technology will allow architects to offer bespoke solutions much more easily. More people will be able to participate in the design in a meaningful way.”
Complementing the transit nature of the tunnel environment, the façade design generates a sense of visual movement and energy for vehicular traffic and passers-by.RPS Group has designed a facade cladding system to Brisbane Australia’s Legacy Way project – a $1.5 billion tunneling project that included the urban and architectural landscape design as well as tunnel portals, ventilation facilities, noise barriers, and roadside landscapes. The project was recently named Australia’s top project at the 2015 National Infrastructure Awards. One key aspect of the design is a facade cladding system developed in collaboration with UAP Factory. The metal bar assembly attaches to the concrete walls and an open facade of the ventilation facility to provide a patterned effect for high-speed vehicular traffic. The digitally sourced pattern is fabricated by twisting steel bars arrayed perpendicular to the viewer. They are selectively twisted to produce momentary thin nodes. These nodes, spread throughout the field of the system, produce a pattern legible at a large scale to high-speed traffic. The assembly is noteworthy for its ability to produce image-like effects with factory-controlled fabrication techniques and conventional installation details. Prefabrication of the panels further added to the economy of the system. “Our aim was to balance Legacy Way’s design and infrastructure components to create an attractive, safe and seamless connection that integrates with local communities,” RPS Landscape Architecture Principal Philip Kleinschmidt explained in a press release. The design team tracked their movements around Australia for one year via GPS, and translated the resulting patterns into a layered graphic patterning system. A base layer of flatbars on edge is fixed back to the building on two horizontal rails. A secondary layer was established by mechanically twisting the flatbar ninety degrees to create undulating fields of solid and void. A tertiary system introduces a ridge detail via triangular fins to create depth change across the facade. These visual effects were then tested through an iterative digital modeling phase. “3d visualization and modeling was used to test pattern applications and understand the overall aesthetic once the system was rolled out en masse,” Amanda Harris, UAP’s Senior Associate and Design Manager, told AN. Harris said that this was a project concerning material properties: “The major constraint was ensuring efficiency of material, investigating and proving up the density (and therefore overall linear meterage) of material required to create the desired visual impact.” Digital models, scale physical models, and eventually larger mockups were produced to allow physical testing of the assembly and to confirm its desired visual effects. Harris said the mockups provided an essential feedback loop: “The twisting process itself was limited by the material, and it was important to understand and avoid twisting radiuses becoming too tight, to avoid causing stress and tearing of the aluminum.”
"Every time we build or renovate a building, we make a public act." - DaeWha KangBy combining contemporary material processes with organic principles, DaeWha Kang Design has transformed a 1980’s-era office building into a new dynamic headquarters for Communique, a public relations firm in Seoul Korea. With a very limited budget, the project team focused on four key points throughout the design process: the production of a human-oriented design, an environmentally responsive facade, a collaborative working environment, and evaluation of design through simulation and measurement. The renovation scope includes retrofitting a ground level parking area into an indoor/outdoor café, re-programming of the office area to maximize daylight for employee desk locations, and a rooftop terrace inspired by traditional Korean hoerang, or circumambulatory walkways. One of the most eyecatching elements of the project is an existing column, on the ground level, clad with a tessellation of silver leaves. The mirror finish stainless steel panels reflect the activity of the street while also visually doubling the height of a relatively low existing space (less than 9 feet). A curved surface between the column and the soffit is realized with singly folded diamond shaped panels, producing a triangulated effect. The pattern expands beyond the intensity of the column, into larger flat shaped panels. This geometry wraps up the facade, producing a primary grid which further warps in response to sightlines of the building from the surrounding urban context. The architects incorporated new high-performance double-glazed units and provided insulation at the exterior walls to combat significant thermal and condensation issues in the existing building. MaCheon grey granite panels regionally sourced provide a strong gray coloration to the facade. DaeWha Kang, Principal of DaeWha Kang Design, says the panels are attached to the facade with a simple bracket and pin anchoring detail allowing for future removal for maintenance if necessary: “That means that even if the building facade needs to be maintained in thirty or forty years time, it will be possible to remove each of the panels from the brackets without damaging them.” Digital analysis tools were employed during the design process to correct existing glare and daylighting issues in the existing space. Solar radiation analysis helped to determine the optimum quantity and location of windows in the office floors, while various window opening directions were tested in a fluid dynamics simulation. The team ended up with a series of casement windows that produce gill-like openings in the building envelope. These openings are paired with louvered blinds on the interior for further glare reduction without blocking air circulation. One of the significant findings from the analysis was that the lower floors required larger openings than the upper floors. Establishing an optimum window opening size allowed the panelization of the facade to geometrically integrate with the openings, creating what Kang calls “a completely organic integration of aesthetics and building performance.” The patterning of the facade was further influenced by standard block lengths from the quarry where the stone was sourced, constructability factors such as the maximum weight for a one-person installation, and the reduction in quantity of more costly curved panel geometry. These constraints produced secondary panelization geometry. A hierarchy between the two grids was visually reinforced by a chamfered corner cut all at primary grid lines, producing a shadow gap along the panel edge. Kang says this architectural process has produced a project that “has content and character, not just branding and image,” and is aligned with broader community ideals: “Projects like this are crucial in Seoul. We must move beyond the city as an accumulation of isolated buildings that do nothing for their surrounding neighborhood, and instead support clients who have a vision to do something more with their ambitions.”
“We don’t need walls anymore. We need living, breathing systems that provide so much more to the urban realm than keeping in conditioned air and keeping out noise and pollutants.” - Will Wright, AIA|LALos Angeles’ 2016 Facades+ Conference, presented by The Architect’s Newspaper, is the 18th event in an ongoing series of conferences and forums that have unfolded in cities across the nation, including New York City, Miami, San Francisco, Dallas, Houston, Seattle, D.C., and Chicago. Held at the L.A. Hotel Downtown, the conference incorporated architects, engineers, fabricators, and innovative material manufacturers into a multidisciplinary two-day event covering the state of building envelope design thinking today. The daylong symposium kicked off with spirited remarks by Will Wright, Director of Government & Public Affairs at AIA L.A., where he set forth a plea for stronger emphasis on localism and craftsmanship. Co-chaired by Kevin Kavanagh and Alex Korter of CO Architects, the event included AIA LA, four local architecture schools – UCLA, USC, Woodbury, and Cal Poly Pomona – and a robust collection of Los Angeles-based architecture firms. Four panel discussions throughout the day covered the influence of building envelopes on business, education, structural design, and data analysis. The conversations engaged audience participation through an interactive, web-based tool called Sli.do. In a morning panel discussion titled “Money Well Spent? An Owner’s Perspective on the Value of Facades,” moderator Kevin Kavanagh spoke with representatives from Kaiser Permanente, Kitchell, and The Ratkovich Company on finding the right balance between aesthetics, energy performance, fiscal responsibility, and efficient project scheduling. During breaks, conference attendees attended a “Methods+Materials” gallery that highlighted innovative building envelope materials such as electrochromic glass, metal mesh fabric with integrated media display, and ultra-compact surfacing products. The symposium was highlighted by keynote addresses from Enrique Norten and Eric Owen Moss. Norten’s opening keynote set forth an argument for a socially responsible architecture integrated into the city via infrastructural, landscape, and public space projects. He cited works of his firm, TEN Arquitectos, which incorporate topographical manipulations of the landscape to establish social spaces of public engagement. His work intentionally camouflages the building envelope into a contextual landscape—be it an adjacent park or cityscape—to dissolve the separation between public and private. Eric Owen Moss spoke in the afternoon, questioning at what point the conceptual content of a project becomes lost amidst constructional realities. Through recent work of his firm, Eric Owen Moss Architects, he focused on building envelope details that strayed from original design intent, transforming in concept and tectonics as engineers, fabricators, and contractors participated in the process. In a panel discussion titled “Bytes, Dollars, EUI: Data Streams and Envelopes,” Moderator William Menking, Founder and Editor-in-Chief of The Architect’s Newspaper, spoke with Atelier 10, Gehry Technologies, and CPG regarding tools and processes facilitating facade analysis and optimization. Sameer Kashyap (Gehry Technologies) shared perhaps the most bewildering stat of the day—that GT was able to script processes which allowed two people to produce over 1200 shop drawings per day for 33 weeks in the coordination of a highly complex facade system. Paul Zajfen of CO Architects rounded out the day with a presentation titled “Facades: A Manifestation of Client, Culture, Climate,” where he argued for contextually specific design producing a facade that “would not be possible at any other time—and in no other place.” The symposium was followed on day two with a series of “dialog” and “lab” workshops covering net-zero facade systems, digital fabrication processes, curtain wall design, and advanced facade analysis. A full roster of organizers and sponsors can be found on the conference website. The Los Angeles event was the first in 2016 of a seven-city lineup, and will be followed by a Facades+AM morning forum in Washington, D.C., on March 10th. The next two-day conference will take place in New York City April 21st and 22nd.
Digitally-fabricated folded aluminum screen animates a utilitarian structure.In the Miami Design District, even the parking garages are works of art. The recently completed City View Garage is no exception, thanks in part to a folded aluminum facade designed by IwamotoScott. Part of a design team that included developers Dacra and LVMH/L Real Estate, architect of record TimHaahs Engineers & Architects, architects Leong Leong, and artist John Baldessari, IwamotoScott crafted a three-dimensional metal screen for the southeast corner of the garage. Digitally fabricated by Zahner, the skin's gradient apertures and color pattern transform a utilitarian structure into an animated advertisement for South Florida's hottest creative neighborhood. IwamotoScott submitted multiple concept designs to the developers. "We had three really different schemes—they ranged in their complexity," said founding partner Lisa Iwamoto. "The one they came back with was the most complex, the most articulated facade. We were really happy with the choice." The final design was influenced by a series of external constraints, beginning with the desire to conceal parked cars from view. "It's a Miami thing; they don't really want to see the cars in the garage," explained Iwamoto. She pointed to the car park at 1111 Lincoln Road, where architects Herzog and de Meuron solved the visibility problem by consolidating the parking spaces at the center of each floor, away from the periphery. "For us that wasn't possible," she said. "The cars come right up to the edge so we had to find other ways of screening them." Another factor was the location of the property line—a mere eight inches out from the floor plate. This left IwamotoScott with less than a foot for both the skin and its supporting structure. "The strategy was how to create some optical three dimensionality, a facade that wouldn't feel static, visually," said Iwamoto. "That was our starting point. Then it was a lot of tweaking and geometric studies for how we could achieve those effects and make it buildable." The metal panels' geometric folds contribute to the feeling of depth, and add the stiffness necessary to meet Miami's heavy wind load requirements. In addition, the folds create a moving display of light and color under the city's ever-shifting skies, observed founding partner Craig Scott. "The faceting of the facade was a double payoff." The aluminum screen comprises five panel types. All have the same border shape, but the dimensions of the apertures change from type to type. In early computer drawings, IwamotoScott modeled each panel type in a different color to keep track of the pattern. Over time, explained Iwamoto, "the colors became important to us, so that's how we rendered it." The client liked it, too, so the screen was ultimately painted in a custom spectrum reinforcing the aperture gradient. But while the facade is in reality a panel system, "we were interested in having it feel more like a mural than panels—almost like a piece of fabric draped over the garage," said Iwamoto. "For us it was important that the seams did not follow a more conventional pattern of vertical lines." The apertures are arranged in an offset grid, and the architects avoided a simple system of vertical supports. Instead, the skin hangs from a collection of staggered aluminum fins affixed to the garage's concrete slabs. Zahner fabricated the metal facade in their Kansas City factory. Because they were working on a design-assist basis, the architects were able to make multiple trips to the production facility. "It was cool, because they would make a panel, and we'd say, 'that's almost right'" before adjusting the angle of the fold by a fraction of a degree, said Iwamoto. "It's amazing how many ways there are to skin a cat." Happily for the architects, Zahner's in-house analysis resulted in a panel system remarkably close to what IwamotoScott had envisioned. "I'm delighted with how we ended up," said Iwamoto. "We did our due diligence [in terms of exploring alternative fabrication schemes], but it wound up that the best way to build it was the way we had conceived it." IwamotoScott also took control of an adjacent section of the garage envelope: an open entry stair, elevator bay, and multistory office block. "That was a bonus for us," said Iwamoto. "Rather than someone else designing it, it just made sense for us to do it—it was really part of our elevation." Because so much of the project budget went to the garage skin, the architects stuck with a basic storefront system. "We wanted to make something simple that still had a design character sympathetic to the garage facade." To create a similar sense of animation, they slightly cantilevered each floor and utilized glass panes of different widths and opacities. IwamotoScott completed work on the office tower through design development; TimHaahs took the reigns when it came to detailing and beyond. Part of why IwamotoScott was particularly eager to design the southeast corner of City View Garage was that it is the portion of the structure directly facing the heart of the Miami Design District. The developers' vision for the neighborhood is "such an ambitious plan overall," said Iwamoto. It is a vision that is rapidly coming to fruition, as she herself has witnessed first-hand. "From the time we started work on the project to when it wasn't even 100 percent complete, the area was transformed," she said. "That's really exciting."
