What if we could “breed” buildings to be more efficient? That’s the provocation by artist, designer, and programmer Joel Simon, who was inspired by the potentials of 3D printing and other emergent digital manufacturing technologies, as well as his background in computer science and biology, to test a system of automated planning. With a series of algorithms of two types—“graph-contraction and ant-colony pathing”—Simon is able to “evolve” optimized floor plans based off different constraints, using a genetic method derived from existing neural network techniques. The results are, according to a white paper he put out, “biological in appearance, intriguing in character, and wildly irrational in practice.” The example he gives is based off an elementary school in Maine. Most schools are long corridors with classrooms coming off the sides, a highly linear design. By attempting to set different parameters, like minimizing traffic flow and material usage, or making the building easier to exit in the event of an emergency, the algorithms output different floor plans, developed on a genetic logic. But this optimization is done “without regard for convention [or] constructability,” and adding other characteristics, like maximizing windows for classrooms, led to complicated designs with numerous interior courtyards. For projects like schools, he suggests, class schedules and school layouts could be evolved side-by-side, creating a building optimized around traffic flow. While perhaps currently impractical (there’s no getting rid of architects—or rectangles— yet!), Simon hopes that the project will push people to think about how building with emergent technologies—like on-site 3D printing, CNC, self-assembling structures, and robotic construction—can be integrated within the design process. These technologies have promises for new forms that are hard to design for, he believes, and potentials that can’t be realized through existing design methods. As he told Dezeen: "Most current tools and thinking are stuck in a very two-dimensional world…[but,] designing arbitrary 3D forms optimized for multiple objectives—material usage, energy efficiency, acoustics—is simply past human cognitive ability."

After four years, NASA’s 3D-Printed Habitat Challenge culminated at Caterpillar's Edwards Demonstration & Learning Center in Peoria County, Illinois, on May 4, with the New York–based AI SpaceFactory taking home the $500,000 first place prize. The competition’s three phases to develop and refine habitats that could be printed from scavenged soil and form a future Martian outpost were subdivided into smaller progressive challenges. The structures would have to be airtight and printed autonomously via drones or another self-deploying mechanism. New York’s SEarch+ and Apis Cor won first place in the complete virtual construction challenge on March 27, where teams were asked to create full-scale digital renderings of their prospective habitats. AI SpaceFactory’s hive-like MARSHA habitat took home the top prize at the next challenge—the company 3D printed a one-third scale model of its prototypical dwelling. Over the course of 30 hours, the 15-foot-tall MARSHA was printed from a plant-based biopolymer mixed with basalt strands, a substrate similar to what would be found on Mars. All three of the windows and the ceiling cap were placed via a robotic arm without human interference. The structure also survived NASA’s crush, impact, and smoke tests better than its competitors. The smoke test is an especially important measure of the habitat’s airtightness, as the fine microparticulate in the Martian environment could damage sensitive equipment and would be difficult to get rid of. The team from Pennsylvania State University took second place and was awarded $200,000. While it may be a while before a MARSHA habitat is erected on another planet, AI SpaceFactory wants to translate the use of structures printed from sustainable biomaterials to the Earthbound construction industry. Enter TERA, an adapted version of MARSHA built using recycled materials from the original structure, that AI SpaceFactory wants to build in Upstate New York. "We developed these technologies for Space, but they have the potential to transform the way we build on Earth,” said David Malott, CEO and founder of AI SpaceFactory, in a press release. “By using natural, biodegradable materials grown from crops, we could eliminate the building industry’s massive waste of unrecyclable concrete and restore our planet.” The company will launch an Indiegogo campaign to realize TERA later this month, and backers will get an opportunity to stay overnight in the research-structure-slash-sustainable-retreat.
New housing is coming to Times Square, at least temporarily. The Virginia Tech team of students and faculty behind the FutureHAUS, which won the Solar Decathlon Middle East 2018, a competition supported by the Dubai Electricity and Water Authority and U.S. Department of Energy, will bring a new iteration of its solar-powered home to New York for New York Design Week in collaboration with New York City–based architects DXA Studio. The first Dubai iteration was a 900-square-foot prefab home, that, in addition to being entirely solar powered, featured 67 “futuristic devices,” centered around a few core areas including, according to the team’s website: “entertainment, energy management, aging-in-place, and accessibility.” This included everything from gait recognition for unique user identities and taps that put out precise amounts of water given by voice control to tables with integrated displays and AV-outfitted adjustable rooms. One of the home’s biggest innovations, however, is its cartridge system, developed over the past 20 years by Virginia Tech professor Joe Wheeler. The home comprises a number of prefabricated blocks or "cartridges"—a series of program cartridges includes the kitchen and the living room, and a series of service cartridges contained wet mechanical space and a solar power system. The spine cartridge integrates all these various parts and provides the “central nervous system” to the high-tech house. These all form walls or central mechanical elements that then serve as the central structure the home is built around, sort of like high-tech LEGO blocks. The inspiration behind the cartridges came from the high-efficiency industrial manufacturing and assembly line techniques of the automotive and aerospace industries and leveraged the latest in digital fabrication, CNC routing, robotics, and 3D printing all managed and operated through BIM software. Once the cartridges have been fabricated, assembly is fast. In New York it will take just three days to be packed, shipped, and constructed, “a testament to how successful this system of fabrication and construction is,” said Jordan Rogove, a partner DXA Studio, who is helping realize the New York version of the home. The FutureHAUS team claims that this fast construction leads to a higher-quality final product and ends up reducing cost overall. The cartridge system also came in handy when building in New York with its notoriously complicated permitting process and limited space. “In Dubai an eight-ton crane was used to assemble the cartridges,” explained Rogove. “But to use a crane in Times Square requires a lengthy permit process and approval from the MTA directly below. Thankfully the cartridge system is so versatile that the team has devised a way to assemble without the crane and production it would've entailed.” There have obviously been some alterations to the FutureHAUS in New York. For example, while in Dubai there were screen walls and a courtyard with olive trees and yucca, the Times Square house will be totally open and easy to see, decorated with plants native to the area. The FutureHAUS will be up in Times Square for a week and a half during New York’s design week, May 10 through May 22.
Brought to you with support fromWASP, a 3D printing studio based out of Italy, recently produced a full-scale residential prototype out of soil, rice products, and hydraulic lime. Measuring approximately 320-square-feet in plan, the project was completed in 10 days and was built in the town of Massa Lombarda in the region of Emilia-Romagna. The project, named Gaia House, aims to establish a template for mass-produced biodegradable and structurally efficient structures. The building rises from a circular concrete foundation, relying on a team-developed computational design to reduce the total quantity of materials while imprinting geometric variation across the facade.
Less than 10 percent of the billions of tons of plastic ever produced has been recycled, with much of it winding up in the Earth's oceans where the plastic disrupts ecosystems and releases toxic chemicals. In response, researchers led by Neri Oxman of MIT’s Mediated Matter Group, which focuses on “nature-inspired design and design-inspired nature,” have devised a new materials that they say, in somewhat biblical terms, go “from water to water.” The substances include a structure made of biocomposite skins derived from cellulose, chitosan, and pectin, some of the most abundant biopolymers on earth, in everything from tree branches to insect exoskeletons to common fruits to human bones. The researchers have put these new composites to the test in a 16-foot-tall pavilion named Aguahoja I (literally, water-sheet in Spanish), the culmination of six years of intense research into material science and robotic fabrication. Panels, comprising a top layer of chitosan and cellulose with a bottom layer of apple pectin and chitosan, were 3D-printed in various compositions to affect their rigidity and strength, color and color-changing abilities, transparency, and responses to heat and humidity, as well as their load-bearing abilities. This means, according to the lab, that the materials are functionally "programmable." Because of this variability, a variety of facade or load-bearing structural components can be generated from the same process, and the size is limited only by that of the printer. This “water-based digital fabrication” is intended to create a situation in which form, function, and fabrication are more closely linked, working in a way that mimics how the natural world designs itself; the result is “a continuous construction modeled after human skin—with regions that serve as structure, window, and environmental filter,” said the lab. In a display at the MIT Media Lab, the pavilion was shown along with a library of materials with various colors, shades, and structural properties, and an array of custom hardware, software, and wetware. The pavilion has been acquired by SFMOMA for its permanent collection, and a second version, Aguahoja II, will appear in the Cooper Hewitt’s design triennial, themed “Nature,” which opens next month. When structures made of these materials have run their course, the materials can be dissolved in water, returning natural materials to the environment with relatively little harm or disruption, much like any organic object in a naturally occurring ecosystem that decays and returns to be reused by the life that relies on it.

After four years, three stages, and countless submissions, NASA’s 3D-Printed Habitat Challenge is winding to a close. The space agency’s competition to design a habitat that could be built on the Moon, Mars, or other planets made of local materials is reaching the final stage, and NASA has awarded $100,000 to be split among the three winners of the complete virtual construction stage. Eleven teams submitted proposals for the complete virtual construction stage, and on March 27, New York’s SEarch+ and Apis Cor took first place and received $33,954.11; the Rogers, Arkansas–based Team Zopherus took second and received $33,422.01; and New Haven, Connecticut’s Mars Incubator placed third and received $32,623.88. The complete virtual construction challenge asked teams to digitally realize their designs in the Martian environment using BIM, building off of an earlier stage in the competition that involved renderings. This time, competitors were judged on the habitat’s layout, programming, scalability, spatial efficiency, and constructability. Smaller 3D-printed models and videos were also produced. SEarch+ and Apis Cor proposed a series of tiered, rook-like towers printed from Martian regolith. The habitat’s hyperboloid shape, resembling a squeezed cylinder, arose naturally from the need to contain the building’s inward pressure; in a low-pressure environment, the greatest force exerted on a pressurized structure is a gas pushing outward (think of inflating a balloon). The habitat’s living areas and laboratories are connected but compartmentalized in case of an emergency thanks to a central service core. Each hexagonal window assembly was designed to be easily assembled in-situ and would contain redundant seals and pressure panes. Zopherus’s concept was simpler and lower to the ground, consisting of a series of latticed domes. The habitat(s) would be assembled by a lander, which would launch a series of autonomous robots to collect the raw materials. It would then mix the materials and print each hexagonal structure from the ground up, making “concrete” from Martian dirt, ice, and calcium oxide. The habitat and adjoining modules would be optimized to capture as much sunlight as possible, but would also include sliding panels to shield the windows for when the solar rays would be too intense. Mars Incubator chose to use a modular panel system for their proposal, utilizing regolith to create the panels’ plates. A central icosahedron would connect to several supplementary pods, and the entire structure would be elevated via a series of support struts, with the critical systems buried below. The primary living space would branch off and connect to a vestibule, multi-use space, and bio-generation pod where plants could be grown. The 3D-Printed Habitat Challenge is part of NASA’s Centennial Challenges program and is managed in part with Bradley University. The complete virtual construction stage was the fourth of five stages in the third phase, and the last leg of the competition will be held from May 1 through 4 at Bradley University in Peoria, Illinois, where teams will 3D print one-third scale versions of their habitats. The winners will split an $800,000 pot.
“What if you could download and print a house for half the cost?” reads the lede for the Vulcan II, a 3D printer with a name suited for sci-fi space exploration, on the website of Austin-based company ICON. Now the company has put this claim to the test, building what it says is the first permitted 3D-printed home in the United States, unveiled during SXSW. Using its original Vulcan gantry-style 3D printer, the firm collaborated with global housing nonprofit New Story to build a 650-square-foot home, which features separate bedroom, living, bathroom, and kitchen areas. The home, called the Chicon House, was printed in under 24 hours and while this test cost around $10,000, the firm estimates that future single-story homes, which could be as large as 2,000 square feet, could be printed for thousands less, around $4,000–$6,500. According to New Story CEO Brett Hagler, there is a pressing need to “challenge traditional [building] methods” to combat housing insecurity and homelessness. He adds that “linear methods will never reach the over-a-billion people who need safe homes.” ICON hopes to leverage the technology to help combat global housing crises all while being more environmentally friendly, resilient, and affordable. The printers use a proprietary “Lavacrete” concrete composite, which is made of materials that can be easily sourced locally and has a compressive strength of 6,000 pounds per square inch. The material is designed to withstand extreme weather conditions to minimize the impact of natural disasters, according to the firm. Wood, metal, and other materials can then be added on for windows, roofs, and the like. The printer relies on an “automated material delivery system” aptly called Magma, which blends the Lavacrete with other additives and water stored in built-in reservoirs. The Lavacrete’s composition is custom-tuned to the particular conditions of each location, accounting for temperature, humidity, altitude, and other climatic features. While 3D printing has been used in a number of architectural experiments over the past few years, it is primarily used as a prefabrication tool, with parts printed offsite to be assembled later. ICON argues that printing a whole home at once with a gantry printer is faster and more reliable. Printing the whole home reportedly provides a continuous thermal envelope, high thermal mass, and extremely little waste. The printers, which are transported in a custom trailer, are designed to work in areas where there is limited access to water, electricity, and the infrastructure necessary for traditional construction techniques—although, at least currently, it seems that some more standard construction is needed to finish off the 3D printed walls and turn them into a home. The Vulcan II is operated by a tablet, has remote monitoring technology, and built-in lighting for building overnight. A specialized software suite helps convert CAD drawings into printable forms. ICON has also begun licensing its tech to others. Austin-based developer Cielo Property Group plans to start production of affordable housing in Austin this year using the Vulcan II, The Wall Street Journal reported.
Being able to translate research finds into practical applications on a construction site is never a sure thing, but having a lab-to-studio pipeline definitely helps. For Jenny Sabin, that means a close integration between her lab at the Cornell College of Architecture, Art, and Planning (AAP), and her eponymous studio in Ithaca, New York. Sabin wears three hats: A teacher with a focus on emerging technologies at Cornell, principal investigator of Cornell’s Sabin Design Lab, and principal of Jenny Sabin Studio. The overlap between the lab and the studio means that Sabin has an incubator for fundamental research that can that can be refined and integrated into real-world projects. When AN last toured the Sabin Design Lab, researchers were hard at work using robot arms for novel 3D printing solutions and were looking at sunflowers for inspiration for designing the next generation of photovoltaics. The projects stemming from fundamental research have been realized in projects ranging from the ethereal canopy over MoMA PS1’s courtyard in 2017 to a refinement of the studio’s woven forms for a traveling Peroni pop-up. Rather than directly referencing nature in the biomimetic sense, Sabin’s projects instead draw inspiration from, and converge with, natural processes and forms. Here are a few examples of what Sabin, her team, and collaborators are working on. PolyBrick Brick and tile have been standardized construction materials for hundreds of years, but Sabin Design Lab’s PolyBrick pushes nonstandard ceramics into the future. The first iteration of PolyBrick imagined an interlocking, component-based “brick” that could twist, turn, and eliminate the need for mortar. PolyBrick 1.0 used additive 3D printing to create hollow, fired, and glazed ceramic blocks that could one day be low-cost brick alternatives that would enable the creation of complex forms. PolyBrick 2.0 took the concept even further by emulating human bone growth, creating porous, curvilinear components that Sabin and her team of researchers and students hope to scale up to wall and pavilion size. PolyBrick 3.0 is even more advanced. The 3D-printed blocks contain microscopic divots and are glazed with DNA hydrogel; the polymer coating can react to a variety of situations. Imagine a bioengineered facade glaze that can change color based on air pollution levels or temperature changes, or a component “stamped” with a unique DNA profile for easy supply chain tracking. Responsive textiles As Sabin notes, knitting is an ancient craft, but one that laid the foundation for the digital age; the punch cards used in early computers were originally designed for looms. As material requirements evolve, so too must the material itself, and Jenny Sabin Studio has been experimenting with lightweight, cellular structures woven into self-supporting forms. Sabin’s most famous such installations are gossamer canopies of digitally knit, tubular structures that absorb, store, and re-emit sunlight at night to illuminate repurposed spool chairs. MoMA PS1’s Lumen for YAP 2017, House of Peroni’s Luster, and the 2016 Beauty-Cooper Hewitt Design Triennial installation PolyThread have all pushed textile science forward. As opposed to rigidly defined stonework or stalwart glass, woven architecture takes on ambiguous forms. As GSAPP’s Christoph Kumpusch pointed out while in conversation with Sabin at the House of Peroni opening in NYC last October, these tensile canopies proudly display their boundary conditions instead of hiding them like more traditional forms. The dangling, sometimes-expanded, sometimes-flaccid fabric cones extrude from the cells of the woven canopy and naturally delineate the programming of the area below. These stalactites create the feeling of wandering through a natural formation and encourage a playful, tactile exploration of the space. Kirigami Origami and kirigami (a form of paper folding that requires cutting) are traditional practices that, like other techniques previously mentioned, have seen a modern resurgence in everything from solar sails to airbags. The Sabin Lab has taken an interest in kirigami, particularly its ability to expand two-dimensional representations into three-dimensional forms. The lab’s transdisciplinary research has blended material science, architecture, and electrical engineering to create rapidly deployable, responsive, and scalable architecture that can unpack at a moment’s notice. Two projects, ColorFolds and UniFolds, were made possible by funding from the National Science Foundation. ColorFolds was realized as a canopy of tessellated “blossoms,” each made from polycarbonate panels covered in dichroic film. The modules open or close in response to the density of the crowd below, creating a shimmering exploration of structural color—3M’s dichroic film produces color by scattering and diffusing light through nanoscale structures rather than using pigments. Visitors below the ColorFolds installation were treated to chromatic, shifting displays of light as the flock-like piece rearranged itself. UniFolds reimagined the Unisphere in Queens’s Flushing Meadow Park as part of the Storefront for Art and Architecture show Souvenirs: New New York Icon, which asked architects and artists to produce objects inspired by New York City icons. The 140-foot-tall, 120-foot-diameter landmarked Unisphere was the centerpiece of the 1964 World’s Fair, and Sabin Design Lab’s UniFolds piece references the utopian aspirations of the sphere and domed architecture more broadly. By using holes, folds, and strategic cuts, Sabin Labs has envisioned a modular dome system that’s quick to unfold and can be replicated at any scale, which is part of the “Interact Locally, Fold Globally,” methodology used to guide both kirigami projects.
ETH Zürich’s high-tech showhome opened its doors this past week. The three-story DFAB HOUSE has been built on the NEST modular building platform, an Empa– and Eawag–led site of cutting-edge research and experimentation in architecture, engineering, and construction located in Dübendorf, Switzerland. The 2,150-square-foot house, a collaboration with university researchers and industry leaders, is designed to showcase robotics, 3-D printing, computational modeling, and other technologies and grapple with the interconnected issues of ecology, economy, and architecture. One of the central innovations is using robots that build onsite, rather than create prefabricated pieces in a factory. This In Situ Fabricator (IF) technology, an autonomous “context-aware mobile construction robot,” helps minimize waste and maximize safety during the construction process. To generate concrete geometries not permitted by conventional construction techniques, such as curvilinear shapes that minimize material use, researchers devised a Mesh Mould technology that was built with the aid of vision system–equipped robots. The robots fabricated a structure that acts as both formwork and structural support, a curved steel rebar mesh. The mesh is then filled with concrete, which it acts as a support to. In the DFAB HOUSE, the Mesh Mould is realized as a 39-foot wall, a main load-bearing component of the house, which is able to carry around 100 tons. Despite its complexity—it has 335 layers with over 20,000 welding points—the robot took just 125 hours to construct the mesh. https://youtu.be/ZeLEeY8yK2Y Cantilevered over the Mesh Mould is the so-called Smart Slab, a 3-D printed concrete formwork that supports the timber structure above. Many of the concrete forms in the home are built with what the researchers are calling Smart Dynamic Casting, an automated prefabrication technology. Robotic prefabrication is also used to make the Spatial Timber Assemblies that comprise the upper two levels of the home. The timber structure was devised as part of a collaboration between the university, Gramazio Kohler Research, and ERNE AG Holzbau, who used computational design to generate timber arrangements to fit into the larger structure. The timber assemblies also permit the creation of stiff structures that don’t require additional reinforcement. Applied onto the structure, the hyper-efficient facade is made of membranes of cables, translucent insulating Aerogel, and aluminum. In addition to all the new technology that went into building the DFAB HOUSE, it will also be a “smart home,” using what the researchers are calling the “digitalSTROM platform,” which includes “intelligent, multi-stage burglar protection, automated glare, and shading options, and the latest generation of networked, intelligent household appliances.” It also includes voice control for many of the home’s operations from turning on a kettle to operating blinds. Energy management is also a centerpiece of the home, with rooftop photovoltaic panels featuring a smart control system. Additionally, heat exchangers in the shower trays recover the warmth of shower water, and hot water from faucets is fed back into the boiler when it’s not in use. Not only does it conserve energy and water, it also prevents bacterial growth in the pipes. The radical use of technology in the DFAB HOUSE is also about optimization and efficiency: the home, with all its undulating formwork and translucent geometries, has been designed to demonstrate how new technology can develop and advance its own aesthetic language to make truly pleasing, compelling spaces. It will also be put to the test. Soon academic guests will be moving in and give life in the DFAB HOUSE a shot. For those who can’t make it to Switzerland, the project will also be presented during Swissnex in San Francisco.
3-D printing in architecture is growing—literally. Once limited to models and small pieces, the technology has recently been adapted to large-scale projects, like the world’s largest 3-D-printed concrete bridge in Shanghai, a stainless steel bridge in the Netherlands, and walls for U.S. military barracks. An Austin-based company has even begun selling plans for 3-D-printed houses, though thus far it seems like none have been built. However, as first reported in 2016, Branch Technology, is set to build what it claims is the “world’s first freeform 3-D-printed house.” The firm has already fabricated an array of projects with its giant 3-D printing armature: furniture, drone landing pads, an award-winning pavilion made in collaboration with SHoP architects for Design Miami in 2016, and what the company claims is the world's largest 3-D-printed structure. However, this would be the first building to be entirely made with the company's printing tech. The project got its start in 2016, when Branch Technology hosted its Freeform Home Design Challenge, inviting firms from around the world to propose a home to be made with its cellular fabrication technology. Out of the nearly 1,300 registrants, the winning entry, called Curve Appeal, came from WATG, and will be completed in partnership with various other firms and labs. The home, which has been designed with attention to the natural light available on the lot in Chattanooga, Tennessee, is intended to be net zero energy. It’s being built out of around 100 pieces of printed carbon-fiber-reinforced ABS thermoplastic, five-pound beams of which have been shown to bear as much as 3,600 pounds. Branch has been testing individual components and structural models, and creep testing the entire system to ensure that every part of the home comes together safely and securely. According to Branch’s David Goodloe, combining lightness with structural integrity defines the firm’s work, making its technology “fundamentally different” than other 3-D-printing construction companies. “Instead of asking 'How much can we 3-D print?'" Goodloe said, “we are asking ‘how little?’” Rather than trying to make components wholly of plastic or another printed material, Branch is leveraging freeform printing to produce what it refers to as a matrix, a lattice-like structure, that supports other materials. The printed form creates the structure to which materials like gypsum composite can be added to increase structural capacity, insulation, and energy efficiency. https://www.youtube.com/watch?v=pUIYAxh0k68 To build bigger, Branch has been scaling up. The company has recently doubled its capacity with four new printers, and is building a new factory to incorporate its advances in automation and speed. The goal, as with many firms and labs experimenting with 3-D printing in architecture and construction, is to bring greater customization to construction. Branch is aiming to complete its home later this year.
Brought to you with support fromIn 2015, the Norwegian Trekking Association announced a decision to construct two warming huts along the mountains that ring the town of Hammerfest to encourage hiking for both residents and tourists. The project brief called for a straightforward structure with a working wood-burning stove, an excellent view of the surrounding landscape, and suitability for the mountainous terrain. Norwegian-based practice SPINN Arkitekter and Britain’s Format Engineers answered this call with a cross-laminated timber shell with exterior Kebony panels.
Rhino Kangaroo and Grasshopper files, the team was able to craft a series of visual models for the project and a series of components that could be easily transported across the mountainous terrain for erection. "Snow simulations were performed to ensure that the entrance will remain snow-free as intended," said the design team. "Structural forces between the panels were determined to specify the correct type of screws and fasteners for the construction. Additionally, 3-D printing was used extensively to test out how the construction would fit together, and to test cladding options for the exterior." The rock-like cabins effectively consist of three layers: a 3-inch-thick CLT shell, a 1/8-inch-thick membrane, and a Kebony skin with a thickness measuring just under 1 inch. A system of frames and blocks are located between the exterior cladding and the CLT core. Two sets of 3.5-inch-thick screws are found on each tile edge, connecting to adjacent tiles and the overall structure. An initial prototype of the $100,000 cabin was constructed in a controlled warehouse environment to allow for the uninterrupted testing of component assembly. Over the course of four workdays, two groups of volunteers assembled the cabin's shell and cut the cladding panels. Following construction, the cabin was split in two and transported via flatbed truck to the site and craned into position for final assembly. Construction of the second cabin is currently in the works.One of the initial challenges of the project was to design a form that both blended in with the rugged setting and endure the harsh mountainous weather conditions. The first step in addressing these conditions called for the 3-D mapping of the two sites with a drone and photogrammetry software. With this territorial information plugged into
