Mitigating the impact of lithium-ion batteries in the energy transition

Spotted: Lithium-ion batteries (LIBs) look set to play a crucial role in the future of energy as the world transitions away from fossil fuels. Found in everything from electric vehicles to smartphones and computers, these batteries have several downsides when it comes to environmental impact. Lithium mining is an extremely water-intensive process that involves the use of toxic chemicals. In fact, producing each tonne of lithium requires 500,000 gallons of water. And exacerbating this problem is the fact that several of the leading lithium-producing regions, such as the Atacama Desert in Chile, are among the world’s driest. 

Innovators are rising to the challenge in several ways. Some are exploring alternative ways of extracting lithium, while others are developing batteries that avoid using lithium (and other minerals with a high environmental impact) altogether. But given the current prevalence of LIBs, and the early stage of alternative technologies, one of the biggest things we can do to mitigate their impact is to invest in effective recycling technologies. 

Canadian company Li-Cycle has developed a two-step recycling process that enables the recovery of critical materials, including lithium, cobalt, and nickel. 

The first step of the process involves breaking down the end-of-life batteries into their component parts. The second step consists of refining the materials into different product streams which can then be used for new batteries.

Unlike other battery recycling processes, which require high temperatures, Li-Cycle’s patented approach relies on chemistry, using unique ‘hydrometallurgical’ technology that is more environmentally friendly. Moreover, traditional approaches to battery recycling typically result in the loss of up to half of the useful recycled material in comparison to Li-Cycle’s 95 per cent recovery rate. The Li-Cycle system can handle batteries of various sizes used for different applications.

The company has recently announced that it plans to expand its operations into Europe. The company will open spoke facilities in Norway and Germany in the first half of 2023, with an aim to recycle 65,000 tonnes of batteries annually by the end of that year. This expansion will help Li-Cycle to meet the growing demand for its services as the world moves toward a more sustainable future.

Other innovations spotted by Sporingwise that re-use end-of-life batteries include e-rickshaws that give a second life to electric vehicle batteries, a startup re-purposing used electric vehicle batteries into home energy storage systems, and technology that yields pure graphite from used lithium-ion batteries.

Want to Stay Relevant in Architecture? Become an Adaptive Reuse or Renovation Expert

Few architectural design processes begin with a blank slate. Rarely is a plot of land as flat and featureless as the sheets of paper used to plan it. This is especially the case in our post-industrial cities, where something likely already exists on that plot. Perhaps a Victorian redbrick or a shingled house that has seen better days? These buildings generally have a host of structural problems that can cause headaches for architects and engineers. And the easiest solution always seems to be to tear it all down and start anew.

But demolishing and starting from scratch is also a lost opportunity to rehabilitate the history and character of a place. By destroying the ‘outdated’ buildings that seem to cause us so many headaches, we are erasing the cultural heritage of our neighborhoods. While preservation projects can be prescriptive, adaptive reuse invites architects the flex their creative muscles by finding a way to express the evolution of a building and neighborhood. Almost paradoxically, renovation projects rely on innovative thought and cutting-edge technologies. Meanwhile, to paraphrase form AIA President Carl Elefante, “the greenest building is one already built”. Retrofitting existing structures is a conscionable alternative to the carbon-intensive nature of new construction.

The Westmount Building, by Dubbeldam Architecture + Design, took home the Popular Choice prize in the 10th Annual A+Awards. The firm transformed a century-old, three-storey brick building — a patchwork of decades-old neglect with mismatched bricks and randomly positioned windows — into a vibrant, urban-oriented community hub.

More and more, adaptive reuse projects are being undertaken by a diverse range of firms — often, these projects are topping awards lists that were once reserved for ground-up constructions. For all of these reasons and more, we are highlighting architecture firms on this week’s job’s board who are willing to give old buildings a second chance. Whether with refurbishing projects or meticulous renovations, these firms are proving that the old can be a fertile source for reinvention. Not all ‘new’ buildings need to be completely new. Sometimes incorporating or preserving elements of old buildings serves as a gift both to the past and to the present.

Tyler Engle Architects — who are currently hiring a Project Architect for their Seattle studio — are no strangers to providing old buildings with a new lease of life.

Freyer Collaborative, an architectural design firm in New York City, also has a diverse portfolio of renovations that stylishly incorporate pre-existing buildings into their high-end residential projects. They are currently looking to hire an Intern Architect.

MJA+A Architects are hiring for an architectural drafter for their offices in New York City. The firm focuses on renovations and restorations for commercial and residential projects both big and small.

Canada Innovation Facts

Global Innovation Index ranking: 16th

Climate targets: cut emissions by at least 40-45 per cent below 2005 levels by 2030, net zero by 2050

Sustainability issues

Oil sands extraction – The Alberta oil sands are the world’s third largest proven oil reserve, and Canada is the largest exporter of oil to the US. Oil sand extraction causes heavy metal pollution and emissions of nitrogen and sulphur oxides, and is a particularly energy and water intensive method of producing oil.

Road salt pollution Canada uses around 5 million tonnes of road salt each year to tackle the country’s treacherously icy driving conditions. This heavy-use of salt has a negative environmental impact, most obviously on vegetaion lining the sides of major roads, but also on aquatic life. 

Air pollution – As in many other countries, air pollution is one of the biggest environmental factors impacting human health in Canada. Poor air quality is linked to 15,300 premature deaths per year in the country, as well as environmental impacts including acid rain and reduced plant growth.

COMFORTABLE OFFICE CLOTHING MADE FROM USED FISHING NETS

One effect of the COVID-19 pandemic is that many of those working from home got used to spending the working day clothed in loungewear – or even pyjamas. Many of those returning to the office have found themselves thinking wistfully back to a time of wearing comfortable clothes. This is the thinking behind Lezé the Label, an entire brand created around loungewear that is comfortable enough to be worn at home and chic enough for the office or an outing. And the twist? The clothing is made using sustainable materials such as recycled fishing nets, sustainably sourced beech trees, and coffee waste. Read more.

Autonomous robots collect seafloor litter
CategoriesSustainable News

Autonomous robots collect seafloor litter

Spotted:  There is an estimated 75 to 119 million tonnes of plastic waste in our oceans today. And while most endeavours to tackle ocean waste have focused on addressing litter floating on the surface, the majority of it is found on the ocean floor.

The underwater environment poses a unique challenge. Traditional methods of cleaning up the ocean floor are both dangerous and expensive, involving human divers who are put at risk every time they descend into the depths. In response, researchers from the EU-funded SeaClear project are developing an AI-based solution for cleaning up the ocean floor without putting human life in danger.

The SeaClear system uses a combination of robotics and machine learning to efficiently locate and remove marine debris. A boat, a drone, two underwater robots, and a collection basket make up the system. The boat functions like a sort of mothership, acting as a communication hub and power source for the robots.

How does it work? The boat marks any large debris encountered on the ocean floor using a type of sonar called a multibeam echosounder. The drones also use sonar to identify large pockets of debris from the air. The underwater robots are then deployed to collect the debris and deposit it in the basket. The whole process is automated, making it much more efficient and effective than traditional methods of marine litter collection.

SeaClear project partner Subsea Tech in France developed the innovative system, which is now being tested in real-world conditions. This new solution has the potential to revolutionise the way we deal with ocean pollution and help to keep our seas clean for future generations.

Other innovations spotted by Springwise that clean up marine litter include okra used to clean up microplastics, a fleet of giant floating barriers tackling the Great Pacific Garbage Patch, and a beer company hosting a tournament to fish plastic out of the ocean.

9 Tutorials To Improve Your Section Renderings

9 Tutorials To Improve Your Section Renderings

The winners of Architizer’s 3rd Annual One Rendering Challenge have been revealed! Interested in next year’s program? Subscribe to our newsletter for updates.  

Sections are integral to understanding any architectural scheme. Whether 2D or 3D, they can give an insight into the varying heights within a model, site conditions, function, material use, light mapping and more. Students and professionals have been experimenting with a variety of styles and techniques to create conceptual and realistic sections to best showcase their proposals. Softwares like Illustrator and Photoshop have also made the task easier, especially when paired with 3D modeling applications and rendering assets.

People creating or inspecting design portfolios now expect drawings that are not only accurate but also have a strong visual appeal. Whether it is a blueprint effect, pop-art palette, x-ray layering or a watercolor effect, every technique contributes something different to the composition. Below is a list of videos that show some different types of sections and how to create them digitally.


Using Photoshop, the above video walks viewers through the different steps of converting a simple line drawing of a section into a rich visual that shows material, depth, light, green cover and more. In addition to the main drawing, there are several smaller steps that can not only apply to sections but can also help enrich other 2D drawings. The tutorial also takes care of less important details that might otherwise be overlooked such as staggering shadows on sloped surfaces and recesses.


The creator has explained how to take a perspective section from SketchUp into a vector drawing on Illustrator to create a minimal black and white render. This is especially helpful to understand how angled sections can be created for structures with irregular forms. Naudet starts with detailed instructions on how to cut a section in a 3D model and add a reference height for human figures as well as faces for shadows on transparent surfaces. The tutorial then moves to Illustrator where we learn how to layer the base image and the shadows and then add humans, manipulate the site and play with line weights.


Street sections are helpful when it comes to showing road widths, tree heights and compound boundaries. The video above shows how to simply and effectively render a cross-section of a road for larger architecture projects, public space designs or urban planning. It starts with a line drawing and builds on it with silhouettes and vector additions of cars and trees along with labels and dimensions.


This video combines the regular view and the hidden line mode and normal mode views in SketchUp to create a conceptual render in Photoshop. There are also tips on how to vary opacity to enhance depth and manipulate line weights, add subtle textures, and correctly use colored lines instead of black for drawings. The technique is an effective way of moving away from traditional sections to more stylistic drawings without compromising on details or accuracy.


More focused on the Photoshop rendering than the original SketchUp model, this lengthy video is a must watch for all looking to create detailed and dramatic section renders. It starts with the basics of masking, introducing textures in perspective and adding noise, before moving into light modifications, building contrast and artistic flourishes. The voiceover is also extremely helpful in understanding the importance of each step and how the different tools and commands work.


This two-part series shows how to build out a landscape section entirely on photoshop. The first video focuses on a basic 2D section with a water body, vegetation and human activity. This is a method that focuses less on accurate site contours and more on the visual impact of the site. However, it is easy to start with a contour diagram from an AutoCAD drawing or SketchUp model and then follow along with the steps as described in the video. The second video shows how to convert the previously created 2D section into a perspective view, again entirely on Photoshop.


There is something very charming about hand-rendered drawings and sketches. However, creating multiple drawings by hand is not only more time-consuming but also can leave less room for modifications. The tutorial above shows a simple way of converting a line drawing imported from any 3D modeling software into a section that appears to be rendered by hand. It uses a variety of brush settings such as size, opacity, spacing and jitter to create realistic shading. While the brushes linked in the description are not available anymore, it might be possible to find similar ones on other websites online.


Paired with a great music selection, this video uses an angled section plane in an axonometric SketchUp view to create a colorful section. The initial part of the video focuses on cleaning up the imported drawing, adding fill to the cut portions and tweaking certain line weights. It shows how adding blocks of color can help differentiate programs and also assist in labeling. The drawing is finished off with painted shadows, tree silhouettes and tags for functions.


A less traditional way of depicting a 3D section is by using a puzzle piece form to cut a section line as opposed to a standard section plane. The video shows how to cut a puzzle piece out of a 3D model in ArchiCAD and clean the model for rendering in Illustrator. The second half focuses on using transparency, adding dotted lines for better understanding, introducing color and more.

A new index shows the influence of climate change in real time

A new index shows the influence of climate change in real time

Spotted: While climate change is undoubtedly leading to more extreme weather events, it can be difficult to understand how climate change is impacting on local weather. After all, how are we to determine if an unseasonably warm day is due to global warming or is simply normal variation in temperature? Climate Central is attempting to answer this question with the Climate Shift Index (CSI), a free tool that reveals the level of influence of carbon emissions on daily high and low temperatures.

Climate Central, is a non-profit organisation and an independent group of scientists who research and report the facts about the changing climate and how it affects people’s lives. Climate Central uses science and big data to generate local information that makes climate change personal and helps show what can be done about it.

The CSI indicates how much more likely or frequent high temperatures and overnight lows have become in a given location. The index uses observation and model-based calculations, along with a clear and easy-to-follow colour-coded map covering the entire continental US, and a simple numeric scale. For example, a CSI level of 3 means the day’s temperatures were made at least three times more likely than they would have been without climate change.

Benjamin Strauss, Climate Central CEO and chief scientist points out that, “Climate change is invisible to most people, but it already affects our daily lives. When it’s too hot to safely work outside, play sports, or walk down a city street, the Climate Shift Index will reveal its fingerprint. When crops wilt, when tornadoes or fires erupt in unseasonal heat, the Climate Shift Index can put those events in context.”

Awareness of the impact of climate change is often seen as a first, and important, step to effecting change. This is why we are seeing a growing number of innovations aimed at measuring local effects of climate change, to help individuals and professionals better counter them. These range from data management platforms aimed at forestry professionals to a ‘heat map’ of climate injustice.

6 Rural Residences Composed of Clustered Volumes

Architects: Want to have your project featured? Showcase your work through Architizer and sign up for our inspirational newsletter. 

Whether on top of the mountain or deep into the woods, staying in close contact with nature can free your heart and mind from exhausting urban life. When designing with rich natural contexts, breaking the architectural volume down into smaller units is an unexpected approach that architects should consider. This strategy allows flexibility in organizing functional spaces, especially when the project needs to cope with the undulating landscape.

Explore with this collection of projects that are clustered in groups of small volumes across stunning landscapes. Instead of a huge, loud form, they communicate with their natural surroundings more harmonically.

Sail House by David Hertz Architects, Studio of Environmental Architecture, Grenadines, Saint Vincent and the Grenadines, 2020
Jury Winner, 2021 A+Awards, Private House (XL > 6,000 sq ft)

Located on one of the beautiful islands of the Grenadines, the Sail House consists of a series of residences overlooking the bay. Hiding in the jungle, there are a primary residence, a caretaker’s residence and several guesthouses, all scattered across the mountainous landscape.

Inspired by the local sailing culture, the roofs are formed by white membranes which are stretched into shapes by steel ‘masts.’ The tensile roofs provide enough shading to keep the residences from overheating. At the same time, the second layer of membranes allows heat to escape from the roof without exposing the interior to rainwater. Rainwater is collected by the roof system and channeled down to the basement through the structural masts. Utilizing the rich precipitation of the site, the sail house is self-sufficient in water.

Knot House by Atelier Chang Ltd, Geoje-si, South Korea, 2014
Jury Winner & Popular Choice, 2015 A+Awards, Hotels + Resorts

The Knot House comprises five sculptural volumes. Five volumes are modular yet closely connected, creating a continuous geometrical form that follows the geological profile. Each knot is a folding shape that provides a private ocean view. The houses are twisted 40 degrees toward the sea to create a triangular private zone by each knot. This twisting exaggerates the dynamicity in the overall form, making the building visible from far away. Among the five knots, the big knot houses a clubhouse and the owner’s residence, and four one-story knots host six guestrooms. Tilted walls and fragmented timber surfaces extend the formal dynamic to interior spaces.

jikka_exteriorjikka_interiorJIKKA by issei suma/SUMA, Shizuoka Prefecture, Japan, 2015

JIKKA is like a bunch of mushrooms growing in the woodland of Shizuoka. The house consists of five huts that together accommodate two ladies in their 60s. Each hut is tailored to fit its program, making them vary in dimensions. The dining/living room and the master bedroom each have a skylight on top, while the other three huts housing the guest room, guest bath and utility room have enclosed, pointed roofs. In contrast to the tall ceiling, the glazed openings are relatively low while meeting the ground. Such form-making strategies create a spacious yet cozy living space.

casa sardinera_farcasa sardinera_poolCasa Sardinera by Ramon Esteve Estudio, Xàbia, Spain, 2014

Casa Sardinera stands on the top of a rockery hill, enjoying an unblock view of the Mediterranean Sea. The building is east-west orientated which facilitates cross-ventilation in the summer and helps capture sunlight in the winter. Adjustable shutters provide shading and privacy for the entry-facing west façade. In contrast, the east façade is made transparent by floor-to-ceiling glazing, generously inviting the attractive landscape into the rooms. The overhangs become sheltered verandas that lead to the outdoor pool and panoramic view of the landscape. While the architectural volumes are rather blocky, white concrete and pale-color timber create a sense of lightness.

Es Pou_aerialEs Pou_exteriorEs Pou by marià castelló, architecture, Balearic Islands IB, Spain, 2021

The project is sited on a rural plot on the island of Formentera. Around the project are farmlands and a flourishing woodland in the west, protecting the house from the setting sun. All three volumes are oriented south-north to avoid overheating. From south to north, the first volume consists of a porch that protects against the burning summer sun. The volume in the middle houses the main living space and the third volume accommodates two bedrooms. The three volumes are similarly white triangular blocks but vary in width, roof plan, and façade openings. Textured with ceramic and wood, the interior has a cozy coolness. Timber breeze walls add textuality to the sleek surfaces while controlling the amount of light and heat that enters the rooms.

Comporta 10_aerialComporta 10_courtyardComporta 10_innerComporta 10 by Fragmentos, Grândola, Portugal, 2021

Comporta 10 is situated in a landscape that features sand dunes and diverse vegetation. The residence comprises a group of one-story white blocks and a courtyard on one corner of the site. The courtyard is loosely enclosed by a group of blocks yet still closely connected to the surrounding natural environment. Living areas and en-suite bedrooms are placed opposite each other and organized by a straight corridor. The kitchen, living room, and dining room enjoy the view of the carefully designed courtyard through large glazed sliding doors. Meanwhile, the bedrooms are rather enclosed that open only toward private verandas and the corridor.

Innovation and SDG 9: Industry, innovation, and infrastructure
CategoriesSustainable News

Innovation and SDG 9: Industry, innovation, and infrastructure

Infrastructure encompasses all the connections that hold the global economy together. Traditionally, these connections have come in the form of buildings, roads, and power supplies. But with the advent of the internet age, cables, wires, data centres, and satellites are increasingly integral to the economy’s nervous system. While many in the developed world take this infrastructure for granted, people in developing countries often lack both physical and digital connections.

Industry sits together with infrastructure as the bedrock of the economy. Today, 23 per cent of the world’s workforce is employed in industry according to the latest figures from the International Labour Organization. And industry has been key to the historic success of the developed world. Sustainable industrialisation is therefore an important priority for those in developing countries.

Global manufaturing took a hit as a result of the COVID-19 pandemic, and the subsequent recovery has been uneven, with less developed countries showing signs of stagnation. At the same time, as the climate crisis becomes ever more urgent, it is important that the economic benefits of industry and infrastructure do not come at an environmental cost that is too high for the world to bear.

Investment in innovation is essential for industrialisation to be sustainable and broad-based in the future – especially in areas of industry that are currently difficult to decarbonise.

Electrification 

Target 9.4 within SDG 9 calls for industrial processes and infrastructure to be upgraded or retrofitted for improved environmental sustainability. One of the challenges when it comes to de-carbonising industry is the need for extremely high temperatures for key processes. At present these temperatures can only be attained economically by burning fossil fuels. Electrification of industrial heating processes is an important goal – especially as most net-zero scenarios envisage electricity generation transitioning almost entirely to renewables. 

Finnish engineering company Colbrook has developed ‘Roto Dynamic Heater’ (RDH) technology that uses electricity generated from renewable sources to reach process temperatures of 1700 degrees Celsius – hot enough to replace fossil fuels in a number of processes previously considered unsuitable for electrification. Elsewhere, Saudi Arabian mining company Ma’aden is planning to replace fossil fuels with solar ‘greenhouses’ to generate the steam needed for aluminium production.

Hi-tech manufacturing

In addition to electrification, hi-tech innovations can also lead to improved efficiency and sustainability. Approximately 45 per cent of electricity generated on earth is consumed by industrial electric motors. Current designs are energy-intensive with metal-to-metal contact between rotating and stationary parts acting as a major source of inefficiency. Finnish startup SpinDrive combats this inefficiency with active magnetic bearings (AMB) technology that levitates the rotating parts of a motor using electromagnetic forces. 

Elsewhere, a new manufacturing process that combines elements of traditional casting with 3D printing produces complex metal parts that are lighter and up to 80 per cent cheaper than the current industry standard. Affordable, lighter components could lead to improved fuel efficiency in the automotive and aerospace sectors.

Transport infrastructure

Roads, railways, ports, and airports are crucial for both the movement of goods and ideas. But millions of people around the world live more than 2 kilometres from the nearest all-season road. Extending transport links in a sustainable way is therefore essential for economic development. German startup Ecopals has developed an asphalt additive made from non-recylable plastic. The enhanced asphalt improves road longevity and reduces the need for virgin materials and petroleum-based products such as bitumen. 

Clean, accessible public transport is particularly important in less developed countries where many do not have the means to own a private vehicle. In Kenya, the Nairobi Metropolitan Area Transport Authority has recently announced that its new Bus Rapid Transit network will be exclusively operated by green vehicles.

Communications and connectivity

In today’s world, internet connectivity is as important as more traditional forms of infrastructure. Yet, to this day, over a third of the world’s population has never been online. Innovators are working to bring connectivity to even the most remote regions. 

Satellite technology is coming on leaps and bounds with companies taking different approaches. Mangata is using a combination of ground-based hubs and high orbiting satellites to make the cloud accessible anywhere. Another company, Astranis,  is using small satellites placed in geosynchronous orbit to provide faster broadband speeds. The company’s satellites are much smaller than other geosynchronous satellites on the market and are consequently much cheaper and faster to manufacture. 

Even where the internet isn’t available at all, innovators are looking to provide connectivity. Bridgefy has developed technology that enables messaging and app access without data or Wi-Fi.

Re-purposing old infrastructure

As the world transitions to a new energy system, much of the infrastructure that powers today’s world will no longer be used. However, innovators are considering a number of ways in which existing fossil fuel infrastructure can be re-purposed to support a cleaner, more sustainable world in the future.

For example, the UK is exploring how coal mines could be used to provide geothermal energy. And sustainable aviation fuel has been successfully piped to New York’s LaGuardia airport using existing petroleum pipelines.

E-rickshaws provide a second life for used electric car batteries
CategoriesSustainable News

E-rickshaws provide a second life for used electric car batteries

Spotted: While electric vehicles certainly release far fewer tailpipe emissions than their internal combustion forebears, the lithium-ion batteries that power most of them face several sustainability issues. One of these is the fact that the average lithium-ion battery is sent to the recycler while still retaining around 70 per cent of its charging capacity. That may not be enough charging capacity for an electric vehicle (EV), but it is enough for other uses. A number of businesses are now popping up to provide a second life for these semi-used batteries. One of these is Nunam.

The non-profit startup based in Berlin and Bangalore is funded by the Audi Environmental Foundation and focuses on developing uses for second-life batteries. Its most recent project, in collaboration with AUDI AG and the Audi Environmental Foundation, is an e-rickshaw powered by used battery modules that spent their first life in an Audi e-tron. The e-rickshaws will be provided to women small business owners in India to use for transporting their goods.

While e-rickshaws are not new to the roads of India, most run on lead-acid batteries, which have a comparatively short service life and are often not disposed of properly – leading to additional pollution. On top of this, most e-rickshaw drivers charge up on the public grid, which gets a large amount of its power from coal. To get around this, Nunam has developed solar charging stations for the rickshaws. During the day, sunlight charges an e-tron battery, and in the evening, the power is passed on to the rickshaws, making local driving largely carbon-free.

Nunam cofounder Prodip Chatterjee describes e-rickshaws as having an ideal eco-efficiency. He explains that, “Car batteries are designed to last the life of the car. But even after their initial use in a vehicle, they still have a lot of their power. For vehicles with lower range and power requirements, as well as lower overall weight, they are extremely promising. In our second-life project, we reuse batteries from electric cars in electric vehicles; you might call it electric mobility ‘lite’.

Rickshaws are just the latest vehicle to join the EV revolution. Their small size makes them perfect for use as EV-powered delivery vehicles. But they are not alone. Springwise has also highlighted other EV delivery or micro-mobility vehicles, including solar-powered tuk-tuks, electric tuk-tuks for use in last-mile delivery, and an autonomous, electric grocery store on wheels.

From the Top: 7 Way Statement Ceilings Can Add an Architectural Punch

The A+Product Awards is open for entries, with a Late Entry Deadline of July 22nd. Get started on your submission today! 

One thing that ties together the Sistine Chapel, The Peacock Room and The Romanian Athenaeum is their majestic ceilings. These buildings are proof that these surfaces can serve a purpose beyond just holding light fixtures. However, excessive embellishments and traditional techniques can look out of place in contemporary homes or restaurants. Below are just a few modern alternatives that ensure that the ceiling takes center stage.

Bella Italia Weine by Ippolito Fleitz Group – Identity Architects, Stuttgart, Germany

Gallery walls are a common occurrence in the Pinterest home décor search results. Another trend is creating a composition of mirrors featuring different design styles to create interest and play with the dimensions of the space. One interpretation of this trend is to adapt it to the horizontal plane or the celling of a room.

This approach is showcased in the Bella Italia Weine in Stuttgart. 90 different mirrors obtained from several rummage sales are mounted on the ceiling, ranging from large rectangular framed ones to decorative handheld mirrors. One of them even features hanging crystal lights to replicate a chandelier. They create broken reflections of the activity below and also imitate the comfort and intimacy offered by the home-style cuisine served here.

ARKHE Beauty Salon by Moriyuki Ochiai Architects, Chiba, Japan

While a sculpture can enhance the look of any space, turning an entire element of architecture into a sculpture can leave a significantly stronger impact. Using different materials, textures and forms in ceilings can create a captivating effect, reflect light in new ways and also help give dimension to an otherwise plain space. In ARKHE Beauty Salon, the firm uses strips of recycled aluminum curled and twisted over and over again on the entire surface to create almost a fluid composition. The firm wanted to replicate the movement of water and the lightness of the hair. The reflection of light on the metal’s surface also mimics the visual of light falling on the surface of the ocean.

Zafar Dental Office by ReNa Design, Tehran, Iran | Images by Reza Najafian

Zafar Dental Office is a great example of how even subtle introductions in a space can make a big difference. Here, they have used small cutouts in the ceiling to hold lights, much like simple cuts in a sheet of paper. These cuts have both sharp profiles as well as sinuous curves. The form is then continued n shelves and seating throughout the space to unify the design. This proves that even small changes in lighting design and geometry can create interest in spaces where it is difficult to add color or protrusions either due to the nature of the function or lack of height.

Over View by FreelandBuck, Pittsburgh, Pennsylvania

Art has been shown to be a successful way of decorating ceilings throughout history. It compels people to stop and look up, changing the way they use and perceive space. Taking this one step further, using optical illusions on the horizontal pain can not only trick people into believing there is a 3D form instead of a plane but also create movement. This helps create the perception of greater floor height as well.  Over View, an installation composed of printed textile pieces, transforms the lobby of the Carnegie Library into a Renaissance-era spectacle. When seen from the center of the room, it appears to have depth and go higher. When seen from other angles, it looks as if it is protruding toward the floor.

Tsujita by SWeet Co, LTD, Los Angeles, California

Being able to look at clouds when dining can make for a thoroughly enjoyable experience. But outdoor dining can also be challenging when grappling with uncertain weather. Interior decorators have often tried to bring the outdoors in by painting murals on walls and ceilings or bringing in greenery. This technique can be altered to better fit fine dining establishments by using a more abstract version of natural elements to add more whimsy. In Tsujita, 25,000 wooden sticks of different lengths are used to create the imagery of clouds. This image changes when seen from different angles due to the space between the sticks.

Vaults and domes have been significant structural elements in religious and cultural buildings throughout history. Now, we can see modern versions in interiors that are purely aesthetic. It can be done by padding beams to create vaulted tops or using wooden panels to add curves to flat surfaces. Another way to add dimension is by using hexagonal and pentagonal forms to create geometric domes as in :PM. The panels also diffuse the color-changing lights placed in this arrangement. This technique combines the charm of conventional domes with the grandeur of chandeliers.

Banq by Office dA, Boston, Massachusetts

There has been an emergence of designs that allows floors, walls and ceilings to blend into one another. Pirogovka Appartment does so by allowing paint from the walls to crawl up the ceiling and floor and a bakery in Oporto continues vertical panels from the wall as swooping curves on the ceiling. Banq in Boston uses wooden slats to create a contouring canopy that continues upwards from the columns. This system also serves an additional function of concealing the old mechanical and structural systems from the previous design. The design also features a wine storage area in the center that becomes a part of this system.
