Ribbons of laser-cut metal lamellas envelop a glass curtain wall.J. MAYER H. Architects designed the sculptural anodized aluminum facade of JOH3, a Berlin apartment building located near both the Friedrichstrasße and Museum Island, as a contemporary echo of its historic neighbors. “The project is located in an old part of Berlin, where there are lots of facades with stucco detail,” said project architect Hans Schneider. “We tried to do something as rich with a new design, something like Jugendstil [the German Art Deco movement] but in a modern translation.” The architects settled on floor-to-ceiling glass wrapped in undulating ribbons of laser-cut aluminum lamellas. They explored the general shape using a physical model, but completed the bulk of the design work in Rhino. Early on, said Schneider, the aluminum tubes that give the envelope its texture “were a bit thicker, a different shape,” but had to be adjusted to trim down the cost of materials. From these basic components, J. MAYER H. Architects made strategic subtractions to deliver a three-dimensional effect. “In the beginning there are tubes, and then we cut out the shapes of the lamellas always different,” explained Schneider. “There are nice interferences when you cut it.” In addition to providing aesthetic interest, said Schneider, “these lamellas protect the interior from the outside without really closing it up.” From straight on, the facade is transparent. From other angles, the overlapping aluminum blades produce varying degrees of opacity. Thus the apartment’s occupants benefit from daylighting without sacrificing privacy. “It’s still quite light, that was the idea,” said Schneider, “to have a really light building in the city but still have [protection].” As well as responding to the stucco detail on the older buildings nearby, JOH3’s organic facade, which was manufactured by Rupert App GmbH+Co. (app) and WICONA and installed by app, draws on the idea of incorporating landscape into the city. This theme amplified in the building’s interior courtyard, where the metal ribbons move in and out of plane to accommodate balconies overlooking a grassy circle. It is also present in the interior. “The floor plans don’t have these rectangular rooms, it’s all more organic,” said Schneider. The balconies and folding windows by Saint-Gobain Glass providing seamless transitions from inside to outside, while each apartment’s lounge is below grade, “so you have different levels, types [of spaces] to make it more like landscape.” The dropped floor from the apartment above is visible in the ceiling below. “That’s also very interesting,” said Schneider, “because you can feel how the different stories merge together.” JOH3’s facade initially drew skepticism from some Berliners, who pressed for a more traditional stucco design. “We had to discuss [it] several times with the city, of course, and especially with the preservation people. There were quite a lot of discussions about color, shape, and material,” said Schneider. But the lamellas, which enact historic and natural references in modern materials, eventually won over the naysayers. “They liked the design totally in the end.”

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. 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.”
An abstracted version of a street tree, a canopy of tessellated irregular polygons balances atop slim steel posts.When Public: Architecture + Communication visited the site of the transit shelters the University of British Columbia had asked them to design, they found that something was missing. The main point of entry to the campus, University Boulevard is lined with trees—except where the bus shelters would go. “There was this language of gaps that we noticed,” said Public’s Christopher Sklar. The shelters themselves, they decided, should fill in the tree line. The designers were left with a question, articulated by Sklar: “How does it be a quiet piece but also something interesting and unusual that relates to its surroundings?” Beginning with the image of a tree’s branch structure, Public placed a wood canopy defined by a repeating pattern atop slim steel posts. As for the pattern itself, the designers considered a range of options, from Moorish patterns to simple geometric shapes. The trouble with a geometric pattern, said Sklar, is that it is “often a static thing. We looked at triangles; they’re just triangles. Add a side, it’s just a square.” But if you add one more side, you have a pentagon. And that is where things get interesting. The tessellation of irregular pentagons is surprisingly complicated, on both a mathematical and an aesthetic level. “The thing that we liked about the repeating pentagon is that it creates something that is repetitive, but it’s also something that’s fluid and dynamic,” said Sklar. “It doesn’t feel like it’s repeating when you’re actually in it. It’s kind of a flowing structure above you.” Public alternated between Rhino and Grasshopper, finding that it was easier to perfect a line drawing and plug it into Grasshopper than to allow Grasshopper to generate the tessellation. “I think it’s one of these things where it’s a new technology, people want to see what it can do, think it can help you generate forms,” said Sklar. “But it’s taking away the last thing we have left to us. We’re designers, we want to shape the thing.” The team built a full-scale model of two of the canopy’s cells to get a sense of their size, hoisting the cardboard shapes onto the ceiling pipes in their Vancouver studio. Structurlam fabricated the Glulam canopy on a Hundegger CNC machine. The steel supports were manually welded at Bosmon Steelworks. The shelter’s concrete benches were also fabricated by hand, at Szolyd. This was a surprise for Sklar, who had delivered a Rhino model of the bench design to the fabricators. But Szolyd said the design, which incorporates a series of fine edges as built-in skate-stops, would require as much work to prep the CNC machine as it would to build a mold manually—so they hired a carpenter to do just that. “Sometimes you do to all this work to make a digital model, and they’re like, ‘no, we’re just going to build it by hand,’” said Sklar. The shelters were assembled by Dan Georzen at Dancin Timber Works. Besides the wood canopy itself, the most dynamic component of the transit shelter is its surround, built of bronze-tinted glass from Columbia Glazing Systems. The tint serves three purposes. First, it cuts down on UV exposure. Second, it will give the canopy a warm cast even as the wood weathers. Finally, it creates a subtle reveal for passers-by. “When you’re approaching the shelter you see it in front of you, you can’t see through the bronze-tinted thing,” said Sklar. “Then when you get under it, it reveals itself to you. As you approach, it reflects its surroundings from all sides; then you get underneath and: ‘oh wow, look at that.’”
Smith|Allen's 3D-printed forest refuge is inspired by the site's patterning and historical cycle of deforestation and regeneration.When Brian Allen and Stephanie Smith first visited the sequoia forest in Gualala, California, they saw patterns everywhere. “We were really intrigued by patterning at many scales, from bark on the trees to light through the trees and also, at a micro scale, [the cells of] the sequioas,” said Allen. Two months later the pair was back, this time with 580 sculptural bricks forming the world’s first 3D-printed architectural installation. Translucent white and 10 by 10 by 8 feet in size, Echoviren resembles a cross between a teepee and a tree stump, a mass made light by the organic porosity of the bricks. Echoviren is intimately tied to its site on the grounds of Project 387, the residency in which Smith|Allen participated last fall. Besides the sequioas’ patterning, the designers drew inspiration from the primitiveness of their surroundings. “The overall form was driven by what is the most basic space we could make,” said Allen. “It turns [out to be] just a small oblong enclosure with an oculus, a small forest hermitage.” The oculus draws the eye up, to the natural roof formed by the sequioas’ branches. In addition, Smith|Allen address the history of the site as a place where regrowth followed the trauma of deforestation. Built of bio-plastic, Echoviren has an estimated lifespan of 30-50 years. “The 50 year decomposition is a beautiful echo of that cycle” of deforestation and resurgence, said Allen. Smith|Allen took a flexible approach to Echoviren’s design, alternating between analog and digital tools. They used tracing paper to extract patterns from photographs of sequoia cells, then trimmed and propagated the patterning by hand. “We initially tried to do it parametrically in Grasshopper, to replicate that cell structure as a generative tool, but we weren’t getting good results,” explained Allen. “For us, the parametric tools were more of a tool set than a generator.” Smith|Allen used KISSlicer to estimate the time required to print Echoviren, 10,800 hours in all. The designers ran seven consumer-grade Type A Machines Series 1 desktop 3D printers for two months straight. They used plant-based PLA bio-plastic, which in addition to being biodegradable, is also readily available. “We wanted to use something commercially available and easy to get our hands on,” said Allen. “The project was not about using inaccessible materials; accessibility gave us the tools to do this.” On-site assembly took four hours. Echoviren is a snap fit system, with dovetail joints in the XY and a pin and socket in the Z. Silicon adhesive secures each layer of bricks to the next. The bottom ring of bricks nestles within a hand-dug trench. Pyramidal in section, Echoviren is a compression structure. Its components vary in thickness from 6-8 inches at the bottom to less than an inch at the top. For Smith and Allen, the magic of Echoviren is twofold. First is the anticipation of the future, of the way the form will change as it decomposes. Just as important is how the installation came to be, how the technology of 3D printing enabled a firm of two to build Echoviren in less than a season. “As young designers, we struggle with getting our work out there and getting it built,” said Allen. “Using 3D printers, we’re able to really increase the amount of stuff we can do in a given time and transition it from a tool of prototyping and model building into real things.”
A bespoke aluminum building skin transforms an abandoned war bunker into a high-performing boutique hotel.Restoration hotelier Unlisted Collection recently acquired a historically listed, vacant municipal building in London’s East End that served as a set favorite for film luminaries like David Lynch. The 1910 Edwardian fore building and its utilitarian 1937 addition had served as the town hall of Bethnal Green before World War II. In order to convert the complex into a boutique hotel, Unlisted hired London-based architecture practice Rare and tasked the firm with designing an addition to the existing buildings to add space for more guest rooms and amenities, while unifying the three disparate elements into a single entity. Rare directors and founders Nathalie Rozencwajg and Michel da Costa Gonçalves answered this last charge with an ornamental screen facade that visually ties together the historic and modern buildings while also improving user comfort and environmental performance. “The yellow brick facade of the 1937 building wasn’t finished due to the outbreak of the Second World War, when it was repurposed as a bunker,” Rozencwajg recently told AN. Since the building had suffered no major damage during the war, the designers had to move forward while abiding by the English heritage guidelines for preserving historical structures, including the decorative Eduardian facade along the street front. To expand square footage and enable the building’s function as a hotel, the team designed a fourth-level add-on for additional guest rooms. The addition is enclosed in a double-glazed curtain wall that is screened by a parametrically designed ornamental skin. Working in a custom-scripted plugin for Rhino, the team designed a pattern for the screen wall derived from an old ventilation grill that they found in the 1937 extension. In developing the pattern, the designers divided the project into three major zones. The uppermost level functions as a brise soleil with a tightly defined pattern that blocks most of the southern sunlight that impacts this part of the building. Toward the center, the pattern is varied, more open in some places and more closed in others to accommodate interior programming—guest rooms feature smaller apertures for greater privacy while the public spaces are clad in a more open screen. At the bottom level, apertures are kept small to provide privacy from street-level passersby. Approximately 980 feet of the building’s surface is wrapped in this screen, fabricated from laser-cut, 4-mm-thick aluminum sheets. Eight 7-by-4-foot panels in varying pattern densities are bolted into a frame that hangs from the curtain wall. At the roof level, the panels were designed to conceal the building’s elevator towers, plenum, and pitched roof profiles. Rozencwajg estimated that unique panel shapes make up 30 percent of the screen system. Each panel was numbered for efficient installation and bolts in each of the panels’ four corners prevent damage from wind and other environmental factors. The modularity of the panel system also provides for future design flexibility. “If you rearrange the space internally and want to reconfigure the facade, you can change out the panels for more or less opacity,” said Rozencwajg. The panels are finished with a metallic powdercoat that changes hue based on the sun’s angle. Since the historical listing prohibited the architects from altering the existing building—including the old sash windows—the new curtain wall had to improve overall building performance. The south elevation features double glazing to minimize heat gain and natural ventilation is enhanced with trickle vents and energy-efficient windows on the new level. The combined efforts resulted in a BREAM rating of Very Good.

Aerodynamics of transit inform the design for new public seating in busy pedestrian areas like train platforms.Landscape architect Thomas Balsley has been shaping public spaces in urban settings for more than 35 years, from the Bronx to Dallas to Portland. Even at large scales his work underscores attention to detail, all the way down to the furniture that adorns his sites. As a resident of New York since the 1970s, Balsley is all too aware of the way public benches and seating function in densely populated cities. For Transit Bench—fabricated by Landscape Forms custom project team at Studio 431—he designed a seating option for busy pedestrian areas, like train platforms and street-side parklets, where movement engulfs stationary seating. “I started thinking of the aerodynamic aspects of transit and airline design, where the skin of the plane is an important structural component,” Balsley told AN. “I had the idea that this folded piece of skin could be the structure.” The bench, which rests on two sled base legs, is one solid form, made from a single sheet of stainless steel with laser cut perforations that suggest motion. Based off his design for the Redline Bench (one of many products Balsley has designed for Landscape Forms), Transit Bench hones in on efficiency of form and material, something he hopes will become hallmarks of 21st century design. Wrestling to rectify an ongoing inconsistency in bench design—“Why isn’t the back as attractive as the front?” pondered Balsley—Transit Bench’s back extends 1/3 of the way down for a more balanced aesthetic. A skirt folds down to conceal the legs at the front of the bench. On the backless version of the design, the skirt wraps down over the backside as well. Rob Smalldon of Studio 431 took the Rhino design files supplied by Balsley and worked on them in SketchUp and SolidWorks. A sheet of stainless steel was laser cut in flat form, and sent to a press break to achieve its three defining bends. For simplicity and consistency, the same dye was used for all three bends. The legs are also made from one band of steel, as are the arms, which are bent to their preferred shape. “I believe some of the best designs are pretty simple,” said Smalldon, “but there’s usually twice as much effort to make it work.” The legs are bolted to the seat panel to avoid heat deformations and ensure safety and stability. “With the bolted connection, you see rounded bolt heads but no warpage,” explained Smalldon. “It looks and performs better.” In all, the bench is made from four pieces. Transit Bench was designed in New York and fabricated in Michigan. Balsley was pleased with the outcome. “If it was a fabricator I wasn’t familiar with, I would have been there. But Landscape Forms is a top shelf company,” he said. “Our other stainless pieces with them have been extraordinary.”
StructureCraft fabricates an orchid-shaped roof that supports vegetation and Living Building Challenge principles.After serving patrons at one of Vancouver’s oldest botanical gardens for nearly 100 years, the VanDusen Gardens Visitors Centre had fallen dangerously into disrepair. Perkins+Will Canada conceived of a new, orchid-shaped center that meets CaGBC’s LEED Platinum ratings, and is the country’s first structure to target the International Living Building Challenge with features like geothermal boreholes, a 75-square meter photovoltaic array, and a timber roof that supports vegetation. To help fabricate the wooden structure to Perkins + Will Canada’s vision, the team contracted StructureCraft, a Vancouver-based design-build studio specializing in timber craftsmanship and structural solutions. Initial designs for the 19,000-square-foot building were delivered to StructureCraft as Rhino files. The uniquely shaped rooftop, which mimics an outline of the indigenous British Columbia orchid, had to be economically fabricated in a way that took net carbon effects into account. Within Rhino plugins—mainly Grasshopper—and with the help of strucutral engineers Fast + Epp, the StructureCraft team sliced the shape of the building into 71 long, curved panels of repeatable geometries. “Each curve is unique, so there’s a different radii for each beam,” said Lucas Epp, a structural engineer who worked on the project. “We optimized the global geometry of the roof so the radii of all the beams were in our fabrication tolerances but still achieved the architect’s desired aesthetic.” Also within Rhino, the team integrated all of the building’s services into each of the panels. Since much of the piping and wiring for other trades like insulation, sprinklers, and electric utilize flexible formats and conduits, modularizing the panels significantly reduced site time from months, to weeks. And to protect the wooden structures, moisture barriers and closed-cell thermal insulation were applied throughout. The parametric model was then imported to Solids modeling software to develop a bespoke fastening system. StructureCraft used jig and table sawing methods to mill panels of Glulam, chosen for its flexibility and strength. Timber battens were affixed as cladding in sizes that were thin enough to naturally accommodate the curves of each panel. Solid timber support columns, carved on StructureCraft’s in-house lathe, taper at both ends to Perkins + Will Canada’s design specifications. Business development engineer Brian Woudstra, who worked on the project, attributed the accuracy of fabrication and the speed of installation to the expansive capabilities of parametric modeling. “We could model every joist, Glulam panel, and ceiling batten to help with conflict detection and feasibility,” he said. “We always prefabricate our projects in our shop, so it’s like a kit of assemblies that all clicks into place.”
A structural, textured metal system wins first place in a competition and the chance to develop a façade with Zahner.Reinforcing the idea that time fosters wisdom, Nicholas Bruscia and Christopher Romano’s third iteration of a structural architectural screen was awarded first place in Tex-Fab’s digital fabrication competition, SKIN. According to Tex-Fab’s co-director, Andrew Vrana, the team’s 3xLP project was selected for its innovative façade system, which uses parametric design and digital fabrication. The 3xLP designers’ exploration of the relationship between academia and manufacturing merged at the University at Buffalo’s (UB) Department of Architecture. Starting their collaborative research with a digital model, Bruscia and Romano solicited the help of local manufacturer Rigidized Metals, (RM), who helped realize the second stage of the project’s evolution with two thin gauge metals featuring proprietary patterns. “The project is important because we’ve partnered so closely with Rigidized Metals,” Roman told AN. “We’ve brought digital and computational expertise, and they’ve provided material knowledge for textured metal—it’s a reciprocal team.” Bruscia said the computational models were heavily informed by material parameters. Working with various patterns in RM’s product library, the team started to see various textures performing differently in structural applications, though the company’s metals are typically used in cladding or decorative applications. “Rigidized Metals’ patterns are stronger than flat metals,” Romano said. “That informed how we selected textures and which became a part of the computational conversation.” Drawn to the geometry of the embossed 4LB sheet, they found the low relief pattern to perform comparably to a deeply stamped-style, and that it complemented other chosen patterns nicely. Structural loading was tested in Karamba, an architect-friendly finite element method analysis plugin for Rhino that was developed recently in Austria. Designed primarily in Rhino 5 and Grasshopper, the team also wrote many of their own scripts. For the SKIN competition, the team adjusted porosity of the screen to increase transparency for façade applications. The screen’s pattern is articulated from all perspectives, creating a dynamic quality that is achieved by a slight twist through the entire structure. “The twist in the system is a result of us getting the geometry on the screen for the system to perform structurally, and to make it possible to fabricate,” Romano said. “Some geometric moves on the screen can be difficult to fabricate, so to remove those you get subtle twisting in the elevation.” At RM’s Buffalo facility, profiles of the system’s components were turret-punched on a CNC, and folded on a press break to achieve a diamond shape. A tabbing system was also milled so the shapes could be fastened with stainless bolts to form a seamless, continuous cell structure. As part of the SKIN competition, Bruscia and Romano will continue working with RM, as well as A. Zahner Company, to fabricate a façade system with a glazing component. The 3xLP team will exhibit their results at the Tex-Fab 5 event in Austin, Texas on February 19.
Francisco Saavedra fabricates a template to scale with large-format, Designjet printers from HP.Founded in 2002, Rojkind Arquitectos is leaving an imprint across its native Mexico through a combination of civic, retail, residential, and hospitality projects. Its innovative design and production methods have garnered international recognition, particularly for projects like Nestlé's Chocolate Museum is in Toluca and innovation lab in Querétaro, and Mexico City’s Tori Tori Japanese restaurant, but the firm also engages in smaller projects and creative diversions that explore new avenues of the design/build process. Casa del Arbol is one such example. Conceived as an add-on for a venerable client, the project is a tree house for the family’s three young daughters. “There was a bird’s nest in the garden when we visited the site,” said Gerardo Salinas, partner at Rojkind. “And a 2-meter space between two trees in the yard was an ideal location that wouldn’t damage the existing trees.” The tree house is composed of three main cocoons in concentric circles making up a clover shape that provides a private play space for each girl. Working in Rhino, the architects emulated the geometry of a bird’s nest by magnifying the twig components into larger branches of wood. At one point, Salinas said the team considered Corian for the entire structure, but wood was a better logistical choice as LED lighting, power, and data were integrated into the design. Final Rhino files were converted to AutoCAD and sent to a large-format HP Designjet T920 printer. Templates were printed on paper in a 1:1 ratio, and used to cut the forms out of MDF. These hard templates were then laid over wood planks to fabricate the final ribs. The architects chose the wood of the Salam tree because it is certified to originate from a regulated forest, an assurance that Salinas said is not easy to find in Mexico. The timber variety also weathers well against the elements and is sealed with wax for added durability. To install Casa del Arbol, Salinas forewent the predictable wood-and-nail method. Steel plates attach to the ribs with stainless steel screws to prevent rotting. This self-securing method also gives the structure an appearance of floating within the trees and reduces direct impact. For privacy and comfort, panels of treated fabric will be secured to the vertical ribs.
Barkow Leibinger designs a precast folded facade that puts a gentle spin on surrounding traditional architecture.On one of the last urban tracts of available land in Berlin, Germany, local architecture firm Barkow Leibinger recently completed an 18-story tower, Tour Total. Highly visible from a neighboring train station, and the first completed project in the site’s 40-acre master plan, the tower has a raster facade with precast concrete panels that were geometrically computed in Rhino to create twisting inflections, conveying a sense of movement around the building’s four sides. As a load-bearing facade, 40 percent of the surface is closed, and 60 percent is triple-glazed, with every other window operable. In addition to integrated energy management strategies—the first building tenant is French energy company Total—partner Frank Barkow said the firm’s extensive background in digital fabrication and research allowed the efficient development of the dynamic facade. Drawing from the surrounding, traditionally quadrilinear brick facades of the 1920s and 30s, the tower’s lines are imbued with an engrained depth that twists optically to read differently in direct sun or cloudy weather, without actually moving. The design team drew a series of T-shaped elements to create the exterior components, and K-modules for structural stability. “The folding K modules produce an in-and-out for continual diagonals that wrap around the corners,” Barkow told AN. Interior and exterior concrete components sandwich around glazing, windows, and insulation. To test the design, 3D models were fabricated on a CNC router. Many of the profiles in the facade assembly are repeated many times, though 160 are unique. Each cast could be used at least half a dozen times before another had to be fabricated. German fabricator Dressler milled plywood molds and white concrete was poured over an affixed release surface. Once solidified, each section was finished with an acid wash to expose the aggregate and transported to the building site. Steel pins, embedded within the structure’s poured concrete floors, connect the layers of the facade sandwich. Barkow and the concrete contractor had several discussions about eliminating an interior precast layer in combination with an Isokorb thermal break to mitigate expansion but, in the end, opted for the original design. “It’s the next technological step, for the facade to work like an exoskeleton, but we’re a few years away from that,” Barkow said. Despite budgetary and time restrictions, the LEED Gold-equivalent Tour Total was realized successfully, in part, through parametric design and advanced fabrication methods. “We’re taking advantage of northern Germany’s extremely proficient building culture and working with our fabricators here and in Switzerland as early as possible in the design process,” said Barkow. “There’s a lot of back and forth where we push them away from conservancy and they push us towards efficiency.”
A new exhibition helps a New York-based firm explore indoor and outdoor applications of a new building material.Cosentino is celebrating Architecture Month with Surface Innovation, a multi-media exhibition at the Center for Architecture in New York that presents innovative applications of its new Dekton material. A combination of raw, inorganic materials found in glass, porcelain, and natural quartz, the new indoor/outdoor surfacing material is made with particle sintering technology (PST) that recreates the natural process of stone formation. The company invited six local architecture firms to design unique projects featuring the material, including SOFTlab, a design/build firm known for its mix of research, craft, and technology in large-scale installations and building projects. For SOFTlab, working with a product that could be used for both interiors and exterior applications was an opportunity to reconcile the growing inverse relationship between the skin and volume of large buildings. “We came up with the idea of building something a little more dense than a single story or residentially scaled building, where Dekton may be used,” said Michael Svivos, founder and director of SOFTlab. “We went to a larger scale building, that blurs the inside and outside.” Starting with the idea of a vertical atrium, which often includes biophilic elements like water features and indoor gardens, the SOFTlab design team envisioned an ATRIUn, a uniquely shaped building feature that uses the durability of Dekton’s stone-like properties to bring the outdoors in. ATRIUn is sponge shaped, and breaches the structure’s exterior at various points. “It forms an interior plaza in a building, not as something that’s flat, but spans the height, width, and depth of the building,” Szivos said. The form was generated in Maya. After inserting the apertures along the quadrilinear volume, the physics simulation plug-in generated the smooth, sinuous surface across various levels. For its larger projects, Szivos says the firm typically solves engineering challenges with Arup through an advanced finite software analysis software program. Those optimized, large designs are then sent to Tietz-Baccon, their long-time local fabricator. However for smaller projects where SOFTlab fabricates its own models and project components, the physics tool provides a close approximation of Arup’s services. To generate a model of ATRIUn’s design for the exhibition, the designers translated the Maya drawing into Rhino with Grasshopper to feed to their in-house laser cutter. Since the design was modeled in paper, four sided shapes were fabricated. If the design was realized in Dekton, triangular shapes would be necessary to achieve the complex curvature of the ATRIUn skin. The set volume was 24 by 24 by 36 inches, scalable for a building between 10 and 12 stories. ATRIUn and Surface Innovation is on view at the Center for Architecture in New York through October 31.
