Ephemeral Field House by design/buildLAB

Virginia Tech students demonstrate a light touch with glass and steel pavilion.

The undergraduate architecture students enrolled in Virginia Tech's design/buildLAB begin each academic year with an ambitious goal: to bring a community service project from concept through completion by the end of the spring semester. In addition to the usual budget and time constraints, the 15 students taking part in the course during the 2013-2014 school year faced an additional challenge. Their project, a public pavilion for Clifton Forge Little League in the tiny hamlet of Sharon, Virginia, was entirely lacking in contextual cues. "It was interesting because our previous design-build projects have been downtown, with lots of context," said Keith Zawistowski, who co-founded and co-directs design/buildLAB with his wife, Marie. "Instead, we had a pristine, grassy field with a view of the mountains. We joke that this is our first group of minimalists." The students' understated solution—three geometric volumes unified by the consistent use of a vertical sunscreen—turns the focus back to the pavilion's surroundings with a restrained material palette of concrete, glass, and steel. Design/buildLAB assigned a separate structure to each element of the Sharon Fieldhouse program, nestling the open-air public pavilion between glass boxes containing the restrooms and concessions kitchen. Different roof heights distinguish the spaces, yet a common material vocabulary and their arrangement along a single horizontal axis allows them to be read as a single object. "The students describe the field house as a linear incision through the site," said Zawistowski. "Basically it's just light cut through the green landscape." Because Sharon Fieldhouse is intended for seasonal use, the students focused on maximizing environmental performance for the warmer months of the year. "Everything's about cooling and ventilation," said Zawistowski. A no-energy ceiling fan cools the kitchen, and tempered laminated white glass helps cut solar gain inside the enclosed areas. "The glass has a translucent quality, so that the spaces are bathed in even light, eliminating the need for electrical lights during the day," explained Zawistowski.

  • System laminated glass wind screens with custom-built steel sunshade
  • Products BMG Metals structural steel, white laminated glass from AGC Glass
The external sunshade, comprising vertical steel plate elements painted white, serves both conceptual and practical ends. "The shade screen is about intimacy and privacy—not just under the open-air pavilion but in the enclosed spaces," said Zawistowski. "The elements vary in density. They're tighter together toward the more private parts of the building." At the same time, larger gaps between the screen's members on the east side of the pavilion welcome in the morning sun, while to the west the steel bars draw together to provide afternoon shade. The screen simultaneously functions as skin and structure. "In most cases, the sunshade is tacked on. In this case it's part and parcel of the architecture," observed Zawistowski. Wider steel bars take the weight of the building's roof, and help conceal downspouts. "Everything is hidden there in the screen," said Zawistowski. "We brought a new group of students to the field house and asked them if they could figure out how rainwater could get off the roof. They didn't know." The students prefabricated portions of the pavilion at Virginia Tech's Blacksburg campus, panelizing the screen members and roofing. "One thing that bothers us in design-build education is that multiple generations tend to work on one project," said Zawistowski. "It's important for us that the same group sees the implications of what they design, so we rely really heavily on prefabrication." On campus, he added, students are able to take full advantage of the university's resources. Once on site in Sharon, the students completed assembly in just a couple of weeks. Given the fact that his students conceived of, fundraised for, programmed, planned, designed, and built Sharon Fieldhouse in less than ten months, it's no surprise that Zawistowski refers to the supernatural when he talks about the project. But when he brings up hocus-pocus, it is as much about the pavilion's aesthetic impression as it is about the speed with which it was brought into being. "We say that it's put together with magic," he mused. "All the connections are hidden—everything's just light and shadow."

Flood-Proof and Floating: Architects unveil open-source plans for a prefab “Floating House”

In an effort to reduce the cost of housing even further, this prefabricated home proposal ditches the cost of a traditional lot entirely. The houseby UK-based Carl Turner Architects doesn't need one—it floats. Essentially a rubber-coated timber box nestled on a 65-foot-by-22-foot flood-proofing concrete tray, the home is outfitted with amenities for total self-sustenance just like a houseboat on open waters. Affixed to the interior is a pair of semi-translucent solar panels measuring 904 square feet, while a rooftop rainwater-harvesting tank—next to the crow’s nest on the rooftop balcony-cum-garden, of course—satisfies all non-drinkable water needs. Inside, meanwhile, the timber walls are bolstered with thick rubber insulation, while the triple-glazed windows keep inhabitants toasty. Space-wise, there is nothing makeshift about this home. The living quarters, contained within a 45-foot-by-16-foot cross-laminated timber frame, consist of two bedrooms, a study, a bathroom, living room, and kitchen. While the tray beneath the house is buoyant (though non-movable), the house is designed to be amphibian: when constructed on land, the base disappears; when assembled on a floodplain, it can be buttressed by stilts or a non-floating, flood-resistant thick concrete base. Like the prefab, the component parts of Floating House can be conveyed to the site by lorry or barge and simply lifted into position. Designed to confront a recent uptick in flood incidents in London, Carl Turner Architects debuted Floating House via the open-source architecture project, PaperHouse. The firm has promised to upload the blueprints to the site, enabling anyone to download them and build their own buoyant home.

Could New York learn from these temporary affordable prefab homes in the Netherlands?

Affordable housing has been a critical part of New York City Mayor Bill de Blasio’s agenda since taking office, promising to create or preserve 200,000 affordable units over the next decade. At a press conference last week, the mayor announced that his administration has made headway toward achieving this ambitious goal, financing over 17,300 affordable homes in the last year (whether his predecessor, Mayor Michael Bloomberg, should have received some credit for this accomplishment has spurred debate). But even with this good news, the demand for affordable housing continues to grow. To help fix this shortage, the administration might want to take a cue from Dutch developer, Heijmans ONE, which has come up with its own win-win idea for alleviating the housing crunch in the Netherlands: putting vacant land to good use with temporary, portable housing. Heijmans ONE designed a one-bedroom prefab house that can be easily assembled in just one day. The house, which rents for  700 euros or $900, kills two birds with one stone: provides an affordable dwelling and activates empty land while construction is stalled on a project. These sleek, pentagonal-shaped homes are designed to have a small carbon footprint, using sustainable wood and solar panels. Once constructed, the house can be connected to the city’s water and sewage, but also designed to operate off the grid. New York City, with its paucity of affordable housing and glut of vacant land, could benefit from this model. Mayor de Blasio and the Department of Housing Preservation & Development have already started rolling out a plan to develop over a 1,000 city-owned properties. In the meantime, why not bring some temporary, affordable housing to sites waiting for long-term development?

Merge Rides the Waves in Bangalore

Modular self-shading system delivers budget-friendly environmental performance.

Tapped to design the facade for the HUB-1 office building at Karle Town Centre in Bangalore, India, New York–based Merge Studio faced a two-pronged challenge: crafting an efficient envelope that would beat the heat without breaking the developer's budget. Moreover, the architects (whose role later expanded to include landscape and public space design) aspired to lend the twelve-story tower, the first in the 3.6 million-square-foot SEZ development, an iconic appearance. "The idea was that we bring together the aesthetics of the facade and make it performative as well," explained Merge founder and advisor Varun Kohli. Despite financial constraints dictated by India's competitive development market, Merge delivered, designing a modular facade comprising metal and glass "waves" that cut solar gain while allowing light and air to penetrate the interior. Solar analysis helped dictate Merge's overall strategy for the building envelope. "In this climate, the maximum impact in terms of heat loads happens through direct radiation, as opposed to conductive heat transfers, which meant that the shading aspect was most important," said Kohli. To lower costs, the architects came up with the idea of a modular, self-shading system in which successive "waves," oriented vertically, shade adjacent glazing. They also streamlined construction through a combination of a minimal material palette and off-site prefabrication. Though Merge had to special-order 1.5-meter Alubond panels, "everything else was fairly simple," said Kohli. "We made sure that there's no glazing where the aluminum panels curve." Mumbai's SP Fab manufactured and installed the facade, splitting each "wave" into three prefabricated pieces that were then trucked to the site and hooked on.
  • Facade Manufacturer SP Fab
  • Architects Merge Studio
  • Facade Installer SP Fab
  • Facade Consultant Environmental Design Solutions (New Delhi, sustainability consultant)
  • Location Bangalore, India
  • Date of Completion 2015
  • System prefabricated modules comprising curved aluminum composite panels and high performance glazing
  • Products Alubond aluminum composite panels, St. Gobain India glazing
HUB-1's glazing was carefully plotted according to the solar studies, with windows decreasing in size on the tower's upper levels. The architects also reduced the window-to-wall ratio on the east- and west-facing sides of the building. They selected double-glazed windows with a low-e coating from St. Gobain India. "It's one of the few buildings using the most high performance glass available in the country," noted Kohli. "It was a careful selection of [performance] strategies." Ventilation is provided by operable vertical slot windows between the crest of each "wave" and the adjacent panel. "Studies showed that we would be able to grab more air through those because of turbulence as it moves around the surface," said Kohli. Some of Merge's initial hopes for improved environmental performance were quashed by the financial reality on the ground. "Obviously, we made a number of compromises along the way," said Kohli. "But I think we can still prove that we were able to save energy in the range of 15-16 percent due to the facade alone." The building as a whole, which will be complete this spring, is targeting LEED Gold certification. Kohli also noted the self-shading system's potential, given a different set of circumstances. "When we first started developing this, we had enough variables that we could really manipulate the facade in response to the environment; the curves could be larger or smaller, and other variables," said Kohli. "But given the fact that we're designing in a market that's very tough financially, we had to really dumb it down. There's quite a bit of [room to explore]."

Unveiled> Norman Foster & Fernando Romero team up to design Mexico City’s new $9.2 billion airport

A new international airport for Mexico City won't just fix the problems of its predecessor—which typically delays planes because the two runways were built too close together—it will be unique in its efficient expansive single enclosure, according to its architects, Foster + Partners and FR-EE. Foster and FR-EE were announced as the winners of a design competition last Tuesday, in which all the finalists had worked with local design talent. Mexico City-based FR-EE's founder Fernando Romero is married to Soumaya Slim, a daughter of Mexican tycoon Carlos Slim. The new airport, which aims to become the busiest in Latin America, has received a $9.17 billion pledge, partly in public land from President Enrique Peña Nieto. The government will finance its early construction, issuing bonds for later stages of development. Officials estimate Mexico will receive $19.6 billion in additional tourism revenue through 2040 as a result of the new airport. It will accommodate more than 100 million annual passengers. At more than 6 million square feet, the new airport will be one of the world's largest. It's also labeling itself the most sustainable. While still a complex committed to promoting air travel, a substantial contributor to global emissions of carbon dioxide, its layout is intended to be entirely walkable and won't need heating or air conditioning for most of the year. Foster + Partner's website said the project will be LEED Platinum:
The entire building is serviced from beneath, freeing the roof of ducts and pipes and revealing the environmental skin. This hardworking structure harnesses the power of the sun, collects rainwater, provides shading, directs daylight and enables views—all while achieving a high performance envelope that meets high thermal and acoustic standards.
Organized around a single massive enclosure, the airport weaves cavernous, naturally ventilated spaces around an organic "X" shape that appears in plan like a cross section of DNA. The lightweight, pre-fab structure will open its first three runways by 2020. Another three runways, set to open by 2050, will quadruple the airport's current capacity. Mexico City's current airport, Benito Juárez International, will eventually be closed and rehabbed into a commercial development and public park. The design competition that preceded this week's unveiling drew high-profile names, including Zaha Hadid, Richard Rogers, and Pascall+Watson. Mexican-American architect and partner at JAHN, Francisco Gonzalez-Pulido, also submitted a design to the competition, but was ultimately unsuccessful. He teamed up with local designers Francisco Lopez-Guerra of LOGUER and Alonso de Garay of ADG for the airport, whose form evokes both flight and traditional Mexican art. A pyramidal arrangement of structural white "umbrellas" transmit light while shielding occupants from the hot Mexican sun.

Prefabricated Glamping Tents by ArchiWorkshop

Dynamic steel and PVDF structures shelter campers in style.

In South Korea, glamping—or “glamorous camping”—is all the rage. The practice combines conventional camping’s affinity for the outdoors with hotel amenities, including comfortable bedding and fine food. Seoul firm ArchiWorkshop’s prefabricated, semi-permanent glamping structures are a design-minded twist on the traditional platform tent. “We [set out to] create a glamping [tent] that gives people a chance to experience nature very close, while also providing a uniquely designed architectural experience,” said partner Hee Jun Sim. “There are many glamping sites in Korea, but they’re actually not so high-end. We were able to bring up the level of glamping in Korea.” ArchiWorkshop designed two models of glamping tents. The Stacking Doughnut is, as the name suggests, circular, with a wedge-shaped deck between the bedroom and living room. “We put the donuts at different angles, stacked them . . . and simply connected the lines. This line became the structure,” explained Sim. “The basic idea was very simple, but in the end the shape was very dynamic.” The Modular Flow is a gently oscillating tube, its sleeping and lounging areas separated by an interior partition. The shape was created from a series of identical modules lined up back-to-front to produce the curve. Both models feature a white, double-layer PVDF membrane stretched over a stainless steel frame. The decks are built of wood, while the interior floors are carpeted in a cream-colored textile flooring product from Sweden.
  • Fabricator Dong-A System
  • Designers ArchiWorkshop
  • Location Danwol-myeon, Yangpyeong-gun, Gyeonggi-do, South Korea
  • Date of Completion 2013
  • Material PVDF, stainless steel, wood, textile flooring
  • Process hand drawing, modeling, AutoCAD, Rhino, 3ds Max, MPanel, laser cutting, welding, bolting
Sim and partner Su Jeong Park “used every possible tool” to design the glamping units. They started with hand sketches, then moved to physical models. “The model wasn’t so simple to make because it was a strong shape [without] straight or fixed walls,” said Sim. Once they had determined a rough form, they bounced among multiple computer programs—including AutoCAD, Rhino, and 3ds Max—to refine the design and create shop drawings. Sim and Park used MPanel to generate the membrane surface. Dong-A System prefabricated the glamping tents off site, laser cutting the components of the steel frame before welding them together. “Because every part of the shape is connected, it had to be super-precise, or the end form would [not be] straight,” said Sim. On site, the structures were simply bolted into place. ArchiWorkshop built eight glamping structures on spec on a site in South Korea. “We actually used the whole site as a test site, to show the world, ‘Hello, we are [here],’” said Sim. The architects are open to adapting the designs to suit different climates or cultures. “What we designed on the test site is very Asian or Korean, a poetic kind of shape, but I think different countries have different clients with different needs,” explained Sim. While Sim acknowledges that there are a number of luxury tents already on the market, he is not concerned. “We had a bit of a late start,” he said, “but we . . . have a different concept with a different kind of approach to the tent.” In the meantime, the challenge of designing outside the box has been its own reward. “We love designing buildings,” said Sim, “but this kind of different structural project is also very refreshing for architects.”

University of Oregon Students Propose Sustainable Wood Housing in Brooklyn

With their winning design for the Association of Collegiate Schools of Architecture’s "Timber in the City" competition, three students from the University of Oregon have imagined wood’s viable potential in prefabricated low-cost housing. Wood construction has been a popular topic at AN recently and the topic of our recent feature, Timber Towers. Benjamin Bye, Alex Kenton, and Jason Rood entered the design competition last year with the mission to create a community of affordable housing and wood technology manufacturing in Red Hook, Brooklyn. Awarded first place, Grow Your Own City proposes the use of CLT (cross-laminated timber) for construction of nearly 183,000 square feet of mid-rise housing, a bike share and repair shop, and a wood distribution, manufacturing, and development plant. The site itself was chosen as a residential and industrial area “in flux;” it is a waterfront neighborhood and competitors were required to balance these elements in a mutually beneficial way. Grow Your Own City designs a mixed-use community of wood production and housing construction, considering a variety of needs. Cost efficient and sustainable, the community is meant to manufacture its own wood, then use onsite development power and technology to build the final product: affordable modular housing units that can be prefabricated in the factory and fit together to form the mid-rise complex. A “supersize plywood” technology that can be prefinished before construction, cross-laminated timber is stronger than regular wood construction and possesses a low carbon footprint. When forested correctly, wood can be a very sustainable and environmentally friendly building material. Most units include windows on two sides and vary in size from a 325 square feet studio to a 990 square feet three bedroom apartment. Impressed with the students’ “mature sensitivity to zoning, politics, and concerns of gentrification” unique to this Red Hook site, the jury of architecture professors, green design architects, and a real estate venture praise the project for several specifics of design. A “green alley” allows for biking, timber education, and sustainable rainwater retention and reuse. And the CLT pods are attractive, livable, and realistic for a variety of occupants and their families. “Overall, the project is strong because it maps out the terrain of the site while remaining consistent to the larger neighborhood in terms of plan, context and materiality,” the jury commented in a statement.

Video> Richard Rogers Builds a Prefabricated Multi-Level House In 24 Hours

With modular homes on the rise, it seems to be time to bid farewell to long months and even years of construction and salute fast-paced, pre-fabricated systems arriving across the globe. At the Royal Academy in London as part of the Inside Out exhibition, Richard Rogers’ firm Rogers Stirk Harbour + Partners (RSHP) has introduced an innovative, environmentally efficient, three-and-a-half story home called the Homeshell. It is meant to inspire discussion about affordable mass housing. The flat-packed home on display contains individually installed windows and boasts a low environmental impact. Colorful facade materials enliven the closed timber frame system. Above: Construction crews raise the building from scratch to fill the courtyard in minutes, piece by piece. Constructed of Insulshell—a malleable, cost- and energy-efficient building system developed by Sheffield Insulated Group and Cox Bench—the Homeshell arrives as flat-pack panels on a single truck and takes a mere 24 hours to construct on site using tilt-up construction techniques. Within the structure, visitors can watch a time-lapse film of the  construction and learn how the building system fits together. The Homeshell is open to the public until September 8, and then the installation will be disassembled and recreated in Mitcham, where it will serve as the showhouse for the YMCA South West Y:Cube Housing project’s potential tenants, designed by RSHP. According to RSHP senior partner Ivan Harbour, the Homeshell “delivers generous space, exceptional insulation, daylight and acoustics. We believe it holds many answers for well-designed and sustainable urban living and could change the way we think about our housing into the future. Having it at the Royal Academy will provoke debate about how architectural innovation might help us meet the UK’s housing needs—for everyone.”

Garrison Architects to Build Modular Pod Hotel in Williamsburg

With one location in Midtown East and another in Murray Hill, Pod Hotel is planning to build a third outpost in Williamsburg, Brooklyn, Capital New York reported. The hip hotel chain has hired prominent prefab proponents Garrison Architects to design their newest location, which will be built using modular construction. According to Curbed, the proposed mixed-use development will be located on a 100,000 square foot site at the corner of Driggs Avenue and North 4th Street and include over 200 guest rooms, as well as retail, a restaurant and bar, roof garden, roof terrace bar and a series of courtyards. For a faster, greener, and cheaper construction process, Garrison Architects plans to piece together the 50-foot-tall hotel using pre-fabricated, 10-foot-by-30-foot components that contain two rooms and a corridor. If these pre-fab plans follow though, it would join two other recent Garrison projects, a disaster housing prototype on Cadman Plaza in Brooklyn and acclaimed lifeguard facilities out on Rockaway Beach in Queens.

Unveiled> Philippe Starck and Riko Design Series of Pre-Fab Homes

[beforeafter]starck_prefab_03a starck_prefab_03b[/beforeafter]   World-renowned designer Philippe Starck has earned yet another feather for his cap in a recent collaboration with Riko, a European manufacturer of sustainable wooden buildings. Stemming from a drive to develop industrially manufactured homes that fulfill housing needs across the globe, the pair created P.A.T.H. (Prefabricated Accessible Technological Homes), a line of 34 turnkey homes merging timeless design, advanced technology, functionality, and sustainability. P.A.T.H. can be customized from layout and interior finishes to distinctive facades and roofing. [beforeafter]starck_prefab_02a starck_prefab_02b[/beforeafter]   Each P.A.T.H. model is characterized by Starck’s signature design, yet homeowners choose each aspect to create their unique spaces. The pre-fab homes provide a range of housing models that vary in size, number of rooms, levels and floor plans. A configurator allows homeowners to browse and select their preferred models. In the early planning stage, all details of the home are meticulously engineered and rendered. Then, bulky building elements such as walls and roof structures are prefabricated, filled with insulation and finished with closing panels in a strictly controlled fabrication facility. The prefabrication system shrinks the amount of time necessary for on-site assembly, which takes several weeks following the completion of the initial infrastructure and foundation. Two months are necessary for electrical and mechanical installations and to outfit the home with the selected finishes. Total time from start to finish is six months. The most sophisticated sustainable construction engineering has been utilized in developing P.A.T.H.  Only high-quality, environmentally friendly materials are used throughout the production and building process. Wood has been selected as the system’s main building material since it is natural and renewable, giving the homes zero-energy or even positive-energy potential.

Garrison Architects to Build Prefab Disaster Housing Prototype in Brooklyn

Brooklyn-based Garrison Architects, a firm well-known for its sustainable modular buildings, and American Manufactured Structures and Services, have collaborated on the design of a prefabricated disaster relief housing prototype, which will be displayed in Downtown Brooklyn this summer, as part of an effort to help rebuild post-Hurricane Sandy with a focus on sustainability. The three-story, three-unit modular test structure will be situated next to the Office of Emergency Management (OEM) on Cadman Plaza. The ground floor will be a handicap-accessible 480-square-foot one-bedroom unit, and the upper two floors will consist of two separate 822-square-foot three-bedroom apartments. The preassembled and pre-furnished units will be 12-feet wide by 40-feet long. Once shipped to the site, they simply need to be clipped together and connected to utilities. They also feature balconies that help lower solar-heat gain, provide larger windows, and supply more habitable space. Garrison Architects principal Jim Garrison told the New York Post that the units can stand alone but are also “designed to operate as a row house and be deployed on a city block.” The prefab structures will cost about $1.14 million paid for by the U.S. Army Corps of Engineers and will include gardens in back and parking in front. They can be assembled to form a secure perimeter around an urban street and can be outfitted with photovoltaics to generate their own electricity. Garrison said that the design, which complies with all city codes, would eventually be utilized for high-density, four-story urban housing. OEM and the Department of Design and Construction have been working since the “What If NYC” design competition in 2008 to create a prototype for disaster housing. When Sandy hit four years later, nothing was prepared. Now, after the establishment of more detailed requirements for local codes, the project is ready to go. Construction is expected to begin soon and test residents will move in for several months to offer feedback on how the units work so the design can be modified.
