Wonder Tree: A Vertical Ecosystem Where Architecture and Nature Converge

Chongqing, China | XISUI Design

In the vast commercial atrium of THE RING · GARDEN CITY in Chongqing, XISUI Design has created Wonder Tree, a monumental installation that challenges the conventional boundaries between architecture, landscape, technology, and environmental education. Rising 20 metres through four levels of retail space and occupying more than 4,000 square metres, the project transforms an interior commercial environment into an immersive, vertical ecosystem.

Part architectural installation, part ecological laboratory, and part fantastical landscape, Wonder Tree imagines a future in which technological innovation is placed in service of ecological restoration. Its language draws from the machinery and optimism of the Industrial Revolution, combining exposed mechanical structures, metallic components, and intricate pipelines with dense vegetation and organic forms.

The result is a contemporary interpretation of the Steampunk aesthetic, but beneath its theatrical appearance lies a more serious proposition: can technology become an instrument for restoring the natural systems that human development has disrupted?

A Fictional Machine for Ecological Restoration

The conceptual narrative imagines the Wonder Tree as a living organism capable of travelling across the planet, purifying damaged environments and restoring ecological balance. Its mechanical components represent humanity’s technological capabilities, while its vegetation and biological systems symbolize the resilience and regenerative capacity of nature.

This narrative unfolds vertically through a sequence of interconnected environments. At ground level, visitors enter through a monumental tree hollow, where metallic machinery merges with roots and branches. The “Seed Museum” functions as the symbolic energy core of the installation, presenting biodiversity as a resource that must be protected and preserved.

Developed in collaboration with Chongqing Natural History Museum, the project incorporates hundreds of rare seeds collected from ecologically diverse regions of China, including Heilongjiang, Ningxia, the Greater Khingan Range, and Xishuangbanna. Interactive displays allow visitors to investigate individual species, transforming the preservation of biodiversity into an accessible public experience.

Above, the “Gene Cabin” represents a controlled scientific environment where seeds are cultivated under protected conditions. The installation’s “World Eye” creates a visual connection between the interior of the tree and the surrounding atrium, reinforcing the project’s emphasis on interaction between people, technology, and living systems.

At the upper level, the “Eden of Lives” represents the transition from controlled cultivation to open growth. Germinated plants emerge into a more natural environment, illustrating the potential of science and technology to support ecological recovery and species diversity.

Making Environmental Systems Visible

One of the project’s most compelling qualities is its attempt to make normally hidden environmental processes visible. Its water purification system, represented through a network of mechanical roots, describes a closed-loop process in which contaminated water is filtered, biologically treated, aerated, sterilized, and ultimately returned to the ecosystem.

Visitors can activate elements of the system through interactive interfaces, observing simulated mechanical filtration, biological purification, and disinfection processes. The result is an unusual fusion of environmental education and entertainment, allowing visitors to engage with the principles of water treatment rather than simply observing them.

The same philosophy informs the air purification strategy. Fans, ventilation systems, plant grow lights, and mechanical pipelines are integrated into the architecture, supporting air circulation and creating suitable conditions for indoor vegetation. Rather than concealing these technical systems, the design incorporates them into the visual language of the Wonder Tree, turning infrastructure into part of the architectural narrative.

A Mechanical Menagerie

The installation’s mechanical creatures further blur the boundary between technology and biology. A five-metre-tall mechanical snail, inspired by industrial turbines and tracked machinery, incorporates a children’s play structure with a spiral staircase, periscope, and slide.

A mechanical dragonfly, conceived as a maintenance technician, introduces a lighter, more delicate counterpart to the installation’s heavy industrial vocabulary. The Great Loong Guardian coils around the tree, simultaneously functioning as a mythical creature and a protective guardrail for the elevated walkways.

A six-metre-tall Divine Bird, inspired by the Qingluan of Eastern mythology, acts as a fictional scout responsible for environmental reconnaissance and information gathering. Together, these creatures create an imagined ecosystem in which mechanical beings and living organisms operate in symbiosis.

Architecture as an Ecological Narrative

The fantasy of Wonder Tree is supported by sophisticated engineering. Its structural system combines a central support column, mechanical roots, aerial roots, and suspended branches connected to the existing building structure. The branching network was algorithmically generated to echo natural growth patterns while satisfying structural loads, spatial requirements, and safety considerations.

The three-dimensional planting system required close collaboration between architects, structural engineers, horticultural specialists, and landscape consultants. Plant species, irrigation, drainage, ventilation, and supplemental lighting were coordinated to create viable growing conditions within the complex interior environment.

Ultimately, Wonder Tree is less a conventional landscape installation than an architectural narrative about ecological responsibility. By placing biodiversity, environmental systems, and technological innovation at the centre of a highly public commercial space, XISUI Design turns sustainability into an experience.

Its greatest achievement may be its ability to make ecological processes tangible. Seeds, water, air, plants, machinery, and people become interconnected components of one continuous system. In this imagined future, technology does not compete with nature; instead, it becomes a means of protecting, regenerating, and learning from it.

Hidden Spa – Water Hope: Regenerating Landscape Through Sustainable Design

Cam Ranh, Vietnam
IDEE Architects

Nestled within the coastal sand dunes of Bãi Dài in Cam Ranh, Vietnam, Hidden Spa – Water Hope, designed by IDEE Architects, demonstrates how architecture can restore and enhance fragile ecosystems rather than simply occupy them. Winner of the Architizer A+Awards 2026 Jury Award in the Spa & Wellness category, the project exemplifies a regenerative approach to sustainable design, where environmental stewardship, climate responsiveness, and human well-being are inseparably connected.

Rather than imposing a building on the landscape, the architects allowed the architecture to emerge naturally from the existing terrain. The spa is carefully embedded beneath the coastal dunes, minimizing its visual impact while preserving the site’s unique topography. By working with the natural contours instead of leveling them, the project significantly reduced excavation,

Material selection further strengthens the project’s sustainability credentials. Locally sourced stone, timber, and bamboo minimize transportation-related emissions while supporting regional craftsmanship and reducing the building’s embodied carbon. These durable natural materials weather gracefully in the coastal environment and establish a timeless architectural language rooted in place.

A vegetated roof serves multiple environmental functions. Beyond allowing the building to blend seamlessly into the surrounding dunes, the planted roof provides additional thermal insulation, reduces heat absorption, supports local biodiversity, and helps manage stormwater runoff. Rainwater collected from the sloping roof is reused to irrigate the extensive landscape, reducing potable water consumption and creating a more resilient water management system.

Perhaps the project’s most meaningful sustainable gesture was preserving a mature tree that stood alone on the site before construction. Rather than removing this natural landmark, the architects organized the entire composition around it, allowing the tree to become the symbolic and ecological center of the project. Its preservation reflects a design philosophy that values existing natural assets as essential components of the architectural experience.

Hidden Spa – Water Hope illustrates that sustainability extends far beyond energy efficiency or technological innovation. Its success lies in its holistic integration of architecture, climate, landscape, and ecology. Every design decision—from preserving the site’s natural contours and existing vegetation to employing passive cooling, renewable natural materials, and water-sensitive landscaping—contributes to a building that works in harmony with its environment.

The project represents a compelling model for tropical architecture in the twenty-first century. It demonstrates that thoughtful, climate-responsive design can deliver exceptional environmental performance while creating restorative spaces that foster health, wellness, and a deeper connection with nature. Hidden Spa – Water Hope stands as an inspiring example of how architecture can heal both people and place, proving that the most sustainable buildings are often those that quietly become part of the landscape they inhabit.

tono Named Best Sustainability Firm at the 2026 Architizer A+ Awards

Recognition highlights a regenerative design approach that integrates biodiversity, fungal networks and traditional Japanese building methods into contemporary architecture.

Japanese architecture practice tono has been named Best in Sustainability Firm at the 2026 Architizer A+ Awards, recognizing its pioneering commitment to regenerative architecture and ecological restoration. Unlike awards that celebrate individual projects, this prestigious honor acknowledges the firm’s overall philosophy and long-term dedication to designing buildings that actively restore the natural environment.

For tono, architecture is not simply about constructing buildings but about strengthening the relationship between people, nature, and the land they inhabit. Every project is designed to enhance biodiversity, improve soil health, protect water systems, and support the complex networks of fungi and microorganisms that sustain healthy ecosystems.

This philosophy is reflected in the firm’s innovative design process. Instead of reshaping landscapes to accommodate buildings, tono works with existing ecological conditions whenever possible. Traditional Japanese construction methods—including stone foundations and charred timber piles—are used to minimize disturbance to the soil while extending the lifespan of the structures. Ecological considerations such as wildlife movement, underground fungal networks, water cycles, and native vegetation become integral components of the architectural design.

The firm’s award-winning residential project, Sumu Yakushima, exemplifies these principles. Carefully integrated into its forest setting, the project demonstrates how thoughtful architecture can preserve biodiversity while creating healthy, comfortable living environments. It has received numerous international honors for combining low-impact construction with long-term ecological restoration.

At the heart of tono’s philosophy is a concept the practice calls KINCHIKU, an architectural approach that recognizes fungi, microorganisms, and living ecological systems as active partners in the design process. This perspective represents a significant shift from conventional sustainable design, emphasizing that buildings should contribute positively to the ecosystems in which they exist.

The recognition from the Architizer A+ Awards reflects a broader evolution within the architectural profession. Increasingly, architects are asking not only how buildings can minimize environmental damage but also how they can regenerate landscapes, restore biodiversity, and improve ecological resilience

“Living in Yakushima completely changed my understanding of sustainability,” says founder Tsukasa Ono. “Rather than simply reducing harm, architecture can become an active participant in restoring living ecosystems. This award suggests that our profession is beginning to embrace that possibility.”

Since 2022, tono has earned more than 40 international design awards, but the Best in Sustainability Firm distinction marks an important milestone by recognizing the firm’s overall vision rather than a single project.

Today, tono works internationally on hospitality, residential, and resort developments, combining traditional Japanese craftsmanship with advanced environmental analysis and life-cycle assessment tools. Guided by the principles of simplicity, harmony, and ecological stewardship, the firm continues to demonstrate that architecture can become a powerful catalyst for environmental regeneration and a healthier future.

Pope Leo XIV presides over solemn mass commemorating hundredth anniversary of Antoni Gaudí’s death and blesses tower of Jesus Christ

This visit from the Pontiff shared with the world the values that inspire the Temple: faith, culture, spirituality and the pursuit of beauty.

The blessing of the tower of Jesus Christ was the central event of Gaudí Year and one of the most significant milestones in the Basilica’s recent history.

10 June 2026 was a historic day for the Basilica of the Sagrada Família, welcoming Pope Leo XIV as part of his Apostolic Journey to Spain and commemorating the hundredth anniversary of Antoni Gaudí’s death. This visit made Leo XIV the third Pontiff to visit the Sagrada Família, after John Paul II and Benedict XVI, who consecrated the Temple and granted it the status of a Minor Basilica in November 2010. Pope’s visit was highly symbolic, coinciding with the hundredth anniversary of the death of the architect who devoted the final years of his life to building the Expiatory Temple.

Solemn mass and blessing of the tower of Jesus Christ

Before the religious service, Pope Leo XIV visited several emblematic spaces at the Sagrada Família, including the Basilica crypt, where he prayed at Antoni Gaudí’s tomb.

At 8:00 pm, the Pope presided over the mass commemorating the hundredth anniversary of Gaudí’s death before thousands gathered inside and outside of the Basilica. The celebration highlighted the relevance of the Catalan architect’s message and his vision of a temple designed to proclaim the Gospel through beauty, light and nature. The day culminated with the blessing of the tower of Jesus Christ, the central event of Gaudí Year and one of the most significant milestones in the Basilica’s recent history. Standing at 172.5 metres, this tower is the highest point of the Basilica and makes the Sagrada Família the tallest church in the world. After the blessing, the Pontiff attended a finale full of light and colour, from the ground up to the first lighting of the cross, culminating with a drone-guided light show that formed the figure of Gaudí and the phrase “Primer l’amor, després la tècnica” (First love, then technique). To wrap up, the Pope unveiled a plaque commemorating his visit to the Basilica.

More than 8,500 people took part in the celebration in person, 4,500 indoors and 4,000 outdoors, while thousands more watched the event on large screens set up in several locations around the city of Barcelona and on the international broadcast.

The visit has once again made the Sagrada Família the centre of global attention and shared with the world the values that inspire the Temple: faith, culture, spirituality and the pursuit of beauty. A hundred years after the death of Antoni Gaudí, this visit from the Holy Father and the blessing of the tower of Jesus Christ were an exceptional tribute to the architect and his dream of building a temple conceived as a great stone Bible, where faith, art and architecture come together to convey the evangelical message.

A cross that reaches the sky above Barcelona

The tower of Jesus Christ is the central tower of the Sagrada Família tower grouping. It is surrounded by the four towers of the Evangelists (each connected to the central tower by a bridge) and the tower of the Virgin Mary (which connects to the tower of Jesus Christ from the inside). It has 12 faces and stands 172.5 metres tall, built with 12 levels of panels that started going in on 16 October 2018, from 85 metres off the ground.

It is topped with a three-dimensional four-armed cross, clad in glass and white enamelled ceramic tiles. The cross is 17 metres tall and 13.5 metres wide.

As noted in the Àlbums de Temple, Gaudí wanted the cross to shine both day and night. So, it features white enamelled ceramic and glass, two shiny materials that can also stand up to exposure to the elements. Plus, spotlights will be installed on the towers of the Evangelists and the towers of the Apostles to illuminate the pinnacle. Inside the cross, there is a sculpture of the Agnus Dei created by Italian artist Andrea Mastrovito following Gaudí’s original project.

After more than 140 years of construction, Barcelona’s iconic Sagrada Família is finally nearing completion. Designed by visionary architect Antoni Gaudí, the basilica has become one of the world’s most recognizable landmarks, attracting millions of visitors each year. The completion of its central towers marks a historic milestone, bringing Gaudí’s ambitious masterpiece closer to the vision he imagined in the late nineteenth century. Combining Gothic and Art Nouveau influences, the structure stands as a symbol of creativity, faith, and perseverance. Its completion not only transforms Barcelona’s skyline but also closes a remarkable chapter in architectural history.

Ferrari Launches Luce, Marking a New Chapter with Its First Fully Electric Car

Ferrari has officially entered the electric era with the unveiling of the Luce, the company’s first fully electric production vehicle, opening what the Italian automaker describes as a new chapter in its history. Designed to combine Ferrari’s long-standing heritage with advanced electric technology, the Luce represents one of the most significant product launches in the company’s modern era. Ferrari says the model has been created not simply as an electric vehicle, but as a Ferrari in every sense of the word.

The name Luce, which translates to “light” in Italian, was chosen to communicate several ideas central to the vehicle’s identity, including lightness, speed, innovation and a sense of the future. Ferrari said the project aims to preserve the emotional and sensory experience traditionally associated with the Prancing Horse while introducing an entirely new technological architecture.

Unlike expectations surrounding a traditional two-seat supercar, Ferrari has introduced the Luce as a four-door, five-seat grand touring vehicle. The company said the design approach was intended to create a versatile car that can combine everyday usability with Ferrari’s performance philosophy. The launch also signals Ferrari’s interest in broadening its audience while maintaining the exclusivity and character that define the brand.

At the center of the Luce is a newly developed electric platform built entirely in Maranello. The vehicle features four independent electric motors, one for each wheel, delivering a combined output of more than 1,000 horsepower. Ferrari says the architecture allows unprecedented precision in vehicle control, with the system independently managing power distribution and vehicle dynamics.

According to the company, the Luce accelerates from 0 to 100 kilometers per hour in approximately 2.5 seconds and reaches a top speed of more than 310 kilometers per hour. The electric grand tourer also offers a driving range exceeding 500 kilometers on a full charge. Ferrari said these figures demonstrate that electrification does not require sacrificing the performance standards associated with the brand.

The Luce also introduces a new design language for Ferrari. The company collaborated with creative collective LoveFrom, founded by Sir Jony Ive and Marc Newson, to develop the vehicle’s visual identity and user experience. Ferrari described the design philosophy as one built around clarity, simplicity and continuity between the exterior, interior and interface.

As Ferrari begins its electric journey, the Luce stands as more than simply the company’s first EV. It serves as a statement about how Ferrari sees the future — one where innovation, technology and performance evolve together while remaining rooted in the brand’s core values.

RND Construction – Cunningham Park Modern

Cunningham Park Modern is a refined reinvention of suburban living that demonstrates how contemporary design and sustainable performance can work in complete harmony. Conceived as a deeply personal response to the homeowners’ aspirations for beauty, comfort, and environmental responsibility, the project transforms a dated, compartmentalized house into a bright, architecturally expressive home tailored to modern family life.

From the outset, the design focused on creating a seamless relationship between interior and exterior spaces. Expansive glazing floods the home with natural light while visually connecting the warm, modern interior to the surrounding landscape. Clean architectural lines, vaulted ceilings, and carefully selected natural materials establish a calm sophistication throughout the residence. The result is a home that feels open and welcoming while maintaining a strong architectural identity.

Inside, the original fragmented layout was completely reimagined into a flowing open-concept plan that supports connection and everyday functionality. The kitchen and dining spaces serve as the social heart of the home, overlooking a backyard designed for year-round enjoyment, complete with a pool, hot tub, BBQ deck, and productive garden beds for vegetable cultivation. Every space was thoughtfully planned to support the owners’ lifestyle, balancing practicality with visual clarity and comfort.

A defining feature of the project is its commitment to high-performance sustainable construction. Certified Net Zero Ready, the home underwent a comprehensive building envelope renovation that included significantly increased insulation, enhanced air sealing, and the installation of high-performance triple-glazed low-E windows. These measures dramatically improved both energy efficiency and occupant comfort. Annual energy consumption was reduced from 139 to 71 GJ/year — a 65 percent reduction — while airtightness improved from 3.68 ACH to an exceptional 0.74 ACH @50Pa. As a result, the home performs 47 percent better than a comparable new home built to current Ontario Building Code standards, while greenhouse gas emissions dropped from 5.6 to 1.2 tonnes annually.

Heating and cooling are primarily provided through an efficient air-source heat pump system, further reinforcing the project’s low-carbon approach. Beyond performance metrics, the home delivers meaningful improvements in indoor comfort, air quality, and long-term operational resilience.

Innovation is also expressed architecturally through several custom features. The suspended living room loft, engineered with structural steel supports and a fully anchored safety net, creates a playful and multifunctional retreat for relaxation and entertainment. One of the project’s greatest technical challenges involved reorienting the original east-facing roof structure to face south in preparation for future solar panel installation. This complex intervention required precise coordination to preserve the home’s openness, airtightness, and thermal performance while achieving the desired solar orientation.

The lower level was equally transformed to support wellness and flexibility, incorporating a custom home gym and office space that respond to evolving patterns of living and working from home. Throughout the project, every intervention was guided by the principle that sustainability should enhance — not compromise — aesthetics, comfort, or functionality.

To extend the project’s impact beyond the home itself, the marketing strategy emphasized education and community engagement. Through digital storytelling, targeted SEO campaigns, AI-driven analytics, video content, and neighbourhood outreach, the project promotes the tangible benefits of high-performance living, including health, comfort, and long-term savings. By positioning sustainability as both aspirational and attainable, Cunningham Park Modern reinforces a broader vision for the future of residential design in Canada.

Reign Architects – House Caroline

In Toronto’s east-end Leslieville neighborhood, a modest mid-19th-century Victorian house has been reimagined into a bright, spatially fluid family home. House Caroline balances heritage preservation with a confident contemporary intervention, where a new A-frame addition redefines the relationship between light, volume, and daily living.

Originally built circa 1850, the 2,200-square-foot structure suffered from the familiar constraints of its era—narrow proportions, compartmentalized rooms, and limited access to daylight. The renovation, completed in 2023, transforms these limitations into opportunities. At its core, the project is less about expansion alone and more about recalibration: of light, circulation, and connection to the outdoors.

The design was guided by two key ambitions: to create a home aligned with the rhythms of a growing family, and to preserve a mature maple tree anchoring the rear yard. This tree becomes both a literal and conceptual focal point, informing the orientation of new openings and the spatial hierarchy of the addition. The result is a house that looks outward.

Inside, precision millwork plays a central role in resolving the home’s narrow footprint. In the dining area, a custom banquette is seamlessly integrated into the existing bay window, softening the geometry while maximizing usable space. The intervention maintains a clear flow from entry to kitchen, reinforcing a sense of continuity across the ground floor.

At the heart of the home, the kitchen and living areas are unified through a continuous wall of oak cabinetry that merges storage, display, and seating. This hybrid element operates as both infrastructure and furniture—housing a media unit, concealing storage, and offering informal seating adjacent to a wood-burning fireplace. The effect is one of quiet efficiency, where utility and atmosphere are tightly interwoven.

Circulation is similarly refined. A compact double-winder staircase replaces a more conventional layout, freeing up valuable square footage and enabling a more generous distribution of program. This strategic move allows for moments of spatial generosity—most notably, a marble-topped kitchen island and improved functionality across all three levels.

Light becomes the project’s defining material. Working within a north-facing condition, the design captures sunlight from above and from the rear, drawing in southern and western exposures wherever possible. On the ground floor, full-height glazing dissolves the boundary between interior and garden, framing views of the maple tree while animating the living spaces with shifting daylight.

The vertical experience of the house is equally considered. An open stairwell leads upward toward a skylight embedded within the A-frame roof, creating a gradual transition from enclosure to openness. Exposed Douglas fir beams articulate the new structure, lending warmth and a tactile connection to the natural world. The interplay of timber, light, and volume culminates in a space that feels both expansive and intimate.

House Caroline is ultimately a study in balance—between old and new, constraint and openness, architecture and landscape. Through careful material selection, integrated design strategies, and a clear sensitivity to context, the project demonstrates how even the most compact urban homes can be transformed into environments of clarity, warmth, and enduring relevance.

San Francisco Firm Re-envisions a 1917 Cottage by Architect Elizabeth Austin

This project encompassed a remodel and a small addition to an existing two-story family home in San Francisco’s Cow Hollow neighborhood. Originally designed in 1917 by architect Elizabeth Austin – one of a small handful of American women architects working in the early 20th century – it was an honor to be tasked with protecting her vision, while ushering the residence into a new époque.

As a historically significant building, it is protected under a landmark preservation scheme that demanded special planning review. The team meticulously restored the facade (during the construction process, every piece of external ornament was removed, labelled, and reinstated) and conceived a series of thoughtful interventions and additions that would enrich the existing. Inside, the architects reimagined the layout to facilitate a more contemporary way of life for their clients.

As well as converting existing crawl space to habitable square footage and making additions at the first and second levels, they completely opened up the central part of the U-shaped plan and removed most of the second floor, creating a double-height dining space at the heart of the home.
