Phone cases have largely settled into two camps: the ones that protect your phone without anyone noticing they exist, and the ones that make a statement with printed graphics, colors, or textures. Neither approach has found a way to make the back of a phone genuinely interesting rather than just decorated. Designer Daniel Idle found a third option that neither camp seems to have considered.
The Terrarium Phone Case is a clear resin case for the iPhone 16 Pro Max with an actual planted environment sealed inside the back cavity. Moss, small-leafed plants, and a stabilized soil substrate are embedded within the transparent shell, creating a thin cross-section of living terrain that you carry around with you wherever the phone goes. It’s a working phone case, a functional terrarium, and an oddly calming thing to have in your pocket all at once.
The construction involved 3D modeling and fabrication in clear resin, producing a case with enough depth in the back wall to house soil, roots, and plant matter. The plants are packed using a stabilized substrate that keeps the arrangement intact when the phone is picked up, rotated, tilted, or slipped into a bag. The camera cutout is fully preserved; the charging port at the bottom remains accessible; the phone continues to work exactly as it always did.
What keeps everything alive inside the sealed cavity is a closed-loop moisture system. The plants and soil generate humidity, which evaporates toward the inner surface of the resin, condenses back into droplets, and cycles down again. Light passing through the clear shell feeds the plants from outside, while the substrate provides gradual nutrient release. The whole thing is, in a fairly literal sense, a miniature ecosystem that sustains itself without any intervention from the person carrying it.
The condensation that forms on the inside of the shell during high-humidity moments is part of the visual appeal rather than a flaw to be engineered away. Seeing that vapor cycle through the case is a reminder that something in there is alive, actively breathing and responding to its environment, in the same pocket or bag as a device specifically engineered to minimize all biological interference.
There’s a running thread through design culture about bringing nature back into objects and spaces that have drifted too far from it. Biophilic design has become a recognizable term for everything from moss walls in offices to plant-filled shelving in apartments. Most of those applications treat plants as decoration layered on top of an existing design. Idle’s approach is different because the plant system isn’t decoration; it’s structural, sealed directly into the object’s body as a core component rather than an afterthought.
Of course, there will be some reservations about putting moisture and soil so close to your phone, which might be resistant to water and dust, but only from brief encounters. Good thing, then, that it’s still a concept project right now. But as a thought experiment about what a phone case could reasonably contain, it lands somewhere between genuinely novel and gently absurd, which is probably the most honest place for a good idea to start.
What if the door you walk through every day was grown from fungi? Danish mycelium company Rebound and architecture studio Det Levende Hus have partnered to create what they claim is the world’s first mass-produced interior door with a core cultivated from fungal mycelium. Currently in the prototype phase, the door is part of a broader collection of bio-based interior and sliding doors designed for modern living spaces, and it may quietly redefine what architectural materials can be.
The concept is straightforward but radical. Rebound cultivates the fast-growing root structure of fungi inside a mould, producing a rigid, lightweight panel with natural sound-absorbing qualities. That mycelium core is then enclosed within a timber frame built from reclaimed and surplus wood, including offcuts sourced from Danish flooring manufacturer Dinesen, meaning the door carries minimal material waste from start to finish.
Rebound co-founder Jon Strunge sees this as a direct challenge to the construction industry’s dependence on slow-growing hardwoods. “We wanted to demonstrate how regenerative, high-performance mycelium-based materials open opportunities for new, innovative, and scalable building components,” he said. The growing process takes roughly two weeks and is designed to scale industrially, making these doors a production-ready proposition rather than a one-off experiment.
What makes the design particularly noteworthy is its adaptability. Colour and surface texture can be altered during the growing process itself, removing the need for post-production finishing. The current prototype presents a smooth, silky surface, but the material can shift in tone and can also be finished with a layer of clay for a warmer, earthier aesthetic.
Structural performance was equally prioritised. A bio-based layer incorporated during the growing process stiffens the door and improves fire resistance, a bio-welding method that adds reinforcement without glue or additional manufacturing stages. The door was also designed to comply with current building standards for private homes, particularly around fire and moisture resistance, making it a credible candidate for real construction.
The first real-world application will be at Kaerhytten, a low-impact housing project in Ramloese, Denmark, designed by architect Jens Martin Suzuki-Højrup, scheduled for completion in 2026. The prototype also features a door handle by architect Bjarne Hammer for Danish brand Randi, the Moom handle cast from recycled seashells, adding a tactile detail that mirrors the door’s material ethos. Looking ahead, Rebound and Det Levende Hus are expanding into mycelium-based acoustic wall panels and ceilings. As Suzuki-Højrup put it, “It’s about how natural materials can transform our experience of space, visually, acoustically, even emotionally.”
The architectural world is shifting toward materials that feel grounded, honest, and deeply connected to the earth. Instead of relying on high-energy industrial products, designers and homeowners are embracing approaches that honor the planet’s natural tectonics. In this movement toward true sustainability, rammed earth has re-emerged as a powerful, modern choice for those seeking beauty, integrity, and a low-carbon footprint.
Its tactile layers and sculptural warmth create spaces that feel rooted, calm, and inherently biophilic. Rammed earth offers durability, thermal comfort, and long-term value, transforming simple structures into timeless experiences and reflecting the five pillars driving its revival.
1. Low-Carbon Construction
Rammed earth stands out as a low-carbon building method because its main ingredient, subsoil, is often sourced directly from the construction site or nearby. This drastically cuts transportation emissions. Unlike concrete or brick, rammed earth requires no firing, kilns, or intensive chemical processes. Its formation relies on simple mechanical compaction and moisture, keeping the embodied energy among the lowest of any mainstream wall system.
This approach makes each project inherently more responsible and materially honest. By using local resources and eliminating energy-heavy manufacturing, rammed earth aligns with global decarbonization goals. It has become a preferred choice among forward-thinking firms committed to sustainable, large-scale performance.
Arquipélago Arquitetos’ Piracaia Eco-Village in rural São Paulo exemplifies sustainable home design, using rammed earth construction to create affordable, eco-friendly residences. Located in the village of Piracaia, the development currently includes three homes ranging from a 538-square-foot studio to a 1,245-square-foot two-bedroom unit. Each home features rammed-earth walls formed from local soil, providing structural strength and natural insulation. A modular design allows the system to be easily replicated or scaled, offering flexibility and efficiency.
Large clerestory windows bring in natural light while preserving privacy, and the aluminium roofs are designed to harvest rainwater for everyday use. Wood panels and steel tie rods ensure stability and structural integrity. Initiated by a resident who sought a deeper connection to nature and community, the project stands as a model for sustainable rural living—embracing local resources, traditional techniques, and modern architectural thinking to shape a more conscious way of life.
2. Honors Raw Materiality
Rammed earth’s signature beauty lies in its dramatic, layered texture, which is an architectural reflection of geological time. Each compacted lift reveals natural striations shaped by the soil’s mineral makeup, giving every wall a distinct, site-specific identity. This visual honesty creates an immediate sense of grounding, making the material feel ancient and deeply contemporary.
In double-height spaces, these walls do more than define boundaries as they hold light, absorb warmth, and shift subtly throughout the day. The result is an atmosphere that feels calm, elemental, and immersive. The wall becomes an artwork in itself, guiding the mood, rhythm, and spatial flow of the entire home.
Japanese architecture studio Lib Work has introduced the Lib Earth House Model B, a 1,076-square-foot home made primarily from 3D-printed soil. Located in Yamaga, Kumamoto Prefecture, and developed with Arup and WASP, this project represents a significant departure from traditional concrete construction. The single-story structure features gently curved walls and a ribbed exterior texture, showcasing the potential of combining ancient materials with advanced printing technology. Constructed from a mix of soil, sand, slaked lime, and natural fibres, the home cuts typical construction emissions by more than half while promoting durability and thermal performance.
Inside, the design balances minimalism and warmth, with natural light accentuating the earth walls’ varied textures. Embedded sensors monitor moisture and structural performance discreetly, improving long-term sustainability. The flat roof accommodates future solar or water systems, highlighting a practical integration of eco-friendly features.
3. Natural Temperature Control
Rammed earth excels in passive design because of its dense, high–high-thermal-mass composition. These walls act as natural thermal batteries, absorbing heat throughout the day and releasing it slowly at night. This steady modulation of indoor temperatures reduces sharp fluctuations and minimizes dependence on mechanical heating or cooling systems. For homeowners and designers, this means long-term savings and an impressive ROI on energy infrastructure.
Beyond performance, the material elevates the visual and spatial experience. Its ability to regulate climate naturally eliminates the need for excessive mechanical fixtures, creating cleaner lines and a more intentional aesthetic. Rammed earth becomes both structure and climate strategy in one.
The Rammed Earth House in Slovenia reimagines the early 20th-century farmhouse by combining ancient building methods with modern solar technology. Designed by architects Merve Nur Başer, Aslı Erdem, and Fatma Zeyneb Önsiper, the tiny home uses rammed earth, a sustainable technique dating back thousands of years – along with a concrete foundation and timber framework. Inspired by Slovenian architect Oton Jugovec’s floating roof, the house also features an extended green roof to protect the structure from erosion caused by Dobrava’s varied climate of rain, snow, and humidity.
Oriented to optimise passive heating and cooling, the Rammed Earth House is carefully positioned to capture winter sunlight and block summer heat. Strategically placed windows enhance natural ventilation throughout the year, while the roof supports solar panels, a rainwater harvesting system, and an integrated septic tank. The interior layout further improves efficiency, with fewer windows on the north side to minimize heat loss and more on the west to capture warmth when needed.
4. Built for Centuries
Modern rammed earth, lightly stabilized with cement, delivers exceptional compressive strength and long-term durability. Its dense composition makes it naturally fire-resistant, pest-resistant, and remarkably stable across changing climates. History reinforces this reliability with rammed-earth structures around the world having survived for centuries, proving the material’s endurance far beyond typical contemporary systems.
For homeowners, this resilience translates directly into value. The walls demand minimal upkeep and offer a long structural lifespan, financially sound over decades. Their inherent thickness also enhances acoustic comfort, reducing noise transfer and improving the quality of everyday living within the home.
Casa Covida is a modern reinterpretation of ancient building methods that merges traditional materials like mud, clay, and straw with advanced 3D-printing technology. Developed by Emerging Objects, the project showcases how earth-based architecture, used by nearly 30% of the global population, can be revived for contemporary living. Built in Colorado’s San Luis Valley using a SCARA robotic printer, the structure is made from an adobe blend and features three interconnected zones: a central space with a hearth, a sleeping area furnished with reclaimed beetle kill pine, and a bathing zone with a river-stone-embedded tub. An inflatable cactus-inspired roof adds weather protection and visual intrigue.
Designed for two people, Casa Covida acts as a prototype to explore how ancient techniques can coexist with digital fabrication. The 3D-printed walls, custom earthen cookware, and natural insulation demonstrate how sustainability and innovation can shape the future of housing.
5. Celebrates Nature-Rooted Architecture
Rammed earth grounds a home not just physically but culturally, drawing directly from the soil that defines its region. By using material sourced from the site itself, the architecture gains a deep sense of place and authenticity. This alignment with biophilic design principles creates a natural, instinctive connection between occupant and landscape, allowing the structure to feel both contextual and emotionally reassuring.
The experience is more than visual as it is tactile and psychological. The walls embody local history, climate, and geology, offering a timeless identity that outlasts design trends. In this way, rammed earth supports well-being while honoring the land it stands on.
Contrary to the belief that sustainability requires sacrificing comfort, Ulaman Eco-Retreat Resort in Bali demonstrates that ecological responsibility can coexist with luxury. Designed by Inspiral Architects, this carbon-neutral resort is constructed primarily from bamboo and rammed earth, locally sourced materials that significantly reduce environmental impact.
Situated in Kaba-Kaba village, the resort showcases the structural and aesthetic potential of sustainable materials. Rammed earth, used for the ground-level walls, offers a low-emission alternative to concrete, while the curvilinear bamboo roofing blends cultural authenticity with structural beauty. Powered by hydroelectric energy from a nearby river, the resort includes a cliffside yoga studio and a meandering pool designed to reflect natural surroundings.
Rammed earth’s resurgence is not a design fad but a meaningful answer to today’s calls for beauty, sustainability, and lasting value. By choosing this ancient yet future-ready material, homeowners invest in sustainable luxury that elevates both life and environment. Its layered, monolithic presence creates a sanctuary that endures quietly elegantly, deeply responsible, and profoundly connected to the earth it rises from.
Most garden structures ask one thing of you: sit still and enjoy the shade. A pergola is a pergola, a gazebo is a gazebo, and neither one particularly cares what the afternoon light is doing. Michael Jantzen’s Interactive Garden Pavilion operates on a different premise entirely, one where the occupant has as much say over the structure as the designer did.
Built from sustainably grown stained wood and painted a uniform forest green, the pavilion sits on an octagonal support frame fitted with 30 slatted hinged panels across its walls and roof. Each panel pivots independently, sliding and rotating along the frame before locking into position. Open them wide on a hot afternoon, and the interior breathes. Angle them down against the glare, and the space dims considerably.
That last point is where the design earns its name. Most adjustable outdoor structures offer a single variable, usually an awning or a retractable canopy, within an otherwise fixed form. Here, the entire skin of the building is the variable. The wall panels, roof panels, and ground-level platform extensions can all be repositioned, which means the pavilion can look substantially different from one afternoon to the next.
Pull the panels shut on three sides, and the structure becomes a genuinely private enclosure. Splay them open, and the interior connects fully to the garden around it. In one arrangement, it reads as a dense closed form. In another, the structure opens up entirely, and the slatted framework becomes almost sculptural against the lawn.
Inside, two benches with adjustable backrests run the length of the interior, facing each other. The seating is built into the frame, which keeps the floor plan clean and leaves room to recline fully. When the overhead panels are partially open, sunlight enters in sharp parallel bands that shift across the benches as the day moves, a quality that is either meditative or distracting depending on what you came in for.
The construction logic is also notably practical. The pavilion is a prefabricated modular system, so the components can be scaled before assembly or joined with additional units to form a larger cluster. No foundation is required in most configurations. Given its size and type, a building permit is unlikely to be needed in many jurisdictions, which removes one of the more tedious barriers between an interesting design and an actual garden.
Jantzen has spent decades proposing architecture that responds dynamically to its occupants, much of it remaining on paper. This pavilion is one of the cases where the idea got built, and the result holds up at close range. The slatted wood is honest about what it is, the green paint ties the structure to the garden without trying to disappear into it, and the hinge mechanism does exactly what it promises.
Most furniture sits in a room without saying much. It fills a corner, does its job, and disappears into the background. Nako Baev’s THE OBJECT 01 is not that kind of furniture. The Amsterdam-based designer set out to build a chair that carries the weight of a spatial statement, something that holds its ground without decoration or apology, and in that specific ambition, the object largely delivers.
THE OBJECT 01 is a 3D-printed lounge chair built from recycled PETG, a plastic more commonly found in water bottles than in furniture workshops. At 20kg, it is lighter than its blocky, slab-heavy proportions suggest, though not exactly something you would reposition on a whim. Its dimensions push it closer in scale to a small architectural fragment than to a typical chair, which is likely the whole point.
The construction follows a modular panel system, where each 3D-printed block fits into a sequence designed to cut material waste and keep the overall mass structurally lean. Finished in a cold grey Baev calls “Kyoto Fog,” the chair reads somewhere between concrete and matte stone. In a sparse studio or raw loft, it anchors the space with quiet authority. In a more conventional living room, it would likely dominate in ways not every household would welcome.
What makes THE OBJECT 01 genuinely worth attention is how honestly it exposes its own making. The layer-by-layer texture from the printing process is not hidden or smoothed away; it stays visible across the surface, turning the manufacturing method into part of the visual language. That kind of material honesty is far more common in ceramics or cast concrete than in plastic furniture, and it gives the piece a tactile quality that polished renders simply do not convey.
Baev describes the design as sitting between furniture and sculpture, drawing on minimalist brutalism and a quieter Japanese restraint in equal measure. The emotional reference points are more unusual: the designer cites the atmosphere of Silent Hill and Half-Life, those game environments built from silence and abandoned space, as part of what shaped the object’s mood.
The workflow involved AI assistance across early form studies, structural testing, and design refinement, reducing development time considerably. That footnote is becoming standard across the industry, and it doesn’t add or subtract much here. This process might even become the key to sustainable furniture design, as it can help optimize 3D printing, increase efficiency, and reduce waste in the long run.
Most of us have a box. Or a bag, or a corner of the closet where clothes go to wait for a fate we haven’t quite settled on yet. Not trash, not donation, just quietly pushed aside. The jeans that stopped fitting but once made you feel unstoppable. The sweater that pilled after three washes but somehow survived four more years. Parting with clothes is harder than it sounds, and the fashion industry has largely treated that emotional gap as a non-problem.
ByBye, a concept designed by Gyeong Wook Kim, Sooa Kim, Gayeon Kim, and Mingyeong Shin, disagrees with that approach in the most literal way possible. It’s a countertop-sized machine that takes your worn and discarded garments and transforms them, through a process of grinding, compression, and heat, into flower pots. Real, usable, actually beautiful flower pots.
Designers: Gyeong Wook Kim, Sooa Kim, Gayeon Kim, Mingyeong Shin
I want to sit with that idea for a second, because it’s a genuinely clever reframe of the problem. The designers describe ByBye not as a disposal system but as a “system of reform.” That language matters. When we throw clothes away, the garments disappear. When we donate, we hand off the moral weight to someone else. But ByBye asks you to stay present for the transformation and gives you something physical to show for it.
The mechanics are straightforward but impressively considered. You feed garments into the top opening, which uses a sliding rail mechanism to regulate input and automatically closes once the designated weight is reached. Inside, a shredder breaks the fabric down into fine particles. Those particles are then fed into a flower pot mold, compressed by a pressing plate, and hardened through high-temperature treatment. The finished pots rise up from the molding mechanism. The whole process takes about ten minutes per piece, and a companion app tracks fabric weight, the number of pots produced, and total production time.
What comes out of the machine is genuinely surprising. The pots carry a terrazzo-like texture from the mixed fibers, soft and speckled in muted blues, pinks, and greens depending on the fabric input. They look like something you’d find at a design fair, not something born from a pile of worn-out t-shirts. That aesthetic outcome feels important to the whole concept. If the result were dull or utilitarian, the emotional payoff wouldn’t land. Instead, you end up with an object that holds some trace of the original garment, and then holds a plant on top of that.
The project raises questions I keep turning over. Can the machine handle all fabric types, including synthetic blends that behave very differently under heat and compression? What’s the upper limit on pot durability when working with processed textiles? These feel like the natural next steps for a concept this promising, and I genuinely hope the team is pushing toward them.
What ByBye gets absolutely right is the emotional architecture of the experience. The name alone, a gentle play on “bye bye” and “by” as in made by, signals that this isn’t designed to make you feel guilty about your wardrobe. The copy throughout the project, “Hello? Nice to Wear You,” “Let Your Clothes Begin Again,” reads more like an invitation than an environmental lecture. That tone is rare in sustainable design, which has a tendency to lead with shame rather than possibility.
The designers put it plainly in their project statement: “Not a system of disposal, but a system of reform where clothing is seen again, and made anew.” That’s a design philosophy worth paying attention to. Fashion produces staggering amounts of textile waste every year, and while no home appliance is going to fix that alone, concepts like ByBye shift the conversation in a useful direction. They make the ending feel less like a loss and more like a beginning. Parting with clothes is still going to feel like something. But now it might feel like planting something too.
