The Spanish Pavilion at the Expo Osaka 2025 is designed by the architecture and design practices Néstor Montenegro (EXTUDIO), Enorme Studio, and Smart and Green Design. This comes after being selected in the public competition organized by the Spanish Cultural Action (AC / E), the institution responsible for representing the country in Universal and International Expositions. Located in the northern section of the 65-hectare Pavilion World, within the thematic area of Connecting Lives, the pavilion highlights the key concepts of Oceand and Sun, Sustainability and Circularity, and Craftsmanship Knowledge. The exhibition will be open throughout the event, until October 13, 2025.
The concept of "sponge cities" has gained prominence since it was introduced by Chinese landscape architect Kongjian Yu, founder of Turenscape, and was officially adopted as a national policy in China in 2013 to combat urban flooding. This approach prioritizes nature-based infrastructure such as wetlands, rain gardens, and permeable pavements, creating landscapes with porous soil where native plants can thrive with minimal maintenance. When it rains, these systems absorb and slow down water flow, reducing flood risks. In contrast, traditional concrete- and pipe-based drainage solutions, though widely used, are costly, rigid, and require frequent maintenance, sometimes even making cities more vulnerable to flooding due to blockages and overflows.
Despite their whimsical appearance, treehouses offer a unique platform for structural innovations and design explorations. Traditional treehouses rely on the trunks of trees for structural support, but, in order to ease the load supported by the tree, contemporary projects often introduce additional systems, such as stilts to maintain the image while offering additional support. One of the key advantages of elevating them in this way is the reduced environmental footprint. Treehouses can be designed to leave the forest floor untouched, preserving small-scale ecosystems. By freeing up the ground below, they minimize disruptions to native flora and fauna, allowing nature to thrive undisturbed. Similarly, many architects use the local topography to create seamless connections, incorporating ramps, stairs, or bridges that integrate with the landscape. These solutions not only improve accessibility but also enhance the overall experience creating an architectural promenade that moves between the treehouse and its surroundings.
"This sensitivity to the environment is reflected not only in the structural design but also in the careful selection of materials. The use of natural materials like wood, also helps the structure blend with its environment. Some designers have gone further by employing alternative materials such as mirrored panels to reflect the surrounding forest and mask the treehouse's presence entirely, demonstrating that the choice of material can contribute to creating a project that feels like an extension of its setting rather than an imposition on it. This collection highlights notable examples from Sweden, Denmark, Indonesia, and France, showcasing their diverse approaches.
As part of our 2018 Venice Architecture Biennale coverage, we present the completed Argentinian Pavilion. Below, the curatorial team describes the exhibition in their own words.
Horizontal Vertigo, Argentinian Pavilion at the Venice Biennale 2018, delves into the notions of humanity and democratic spirit as proposed by Freespace, by establishing a cross-cutting dialog between geography, place, and architecture.
The exhibition, curated by the architects Javier Mendiondo, Pablo Anzilutti, Francisco Garrido and Federico Cairoli, is an invitation to rethink our territory as a collective construction and discover architecture in its capacity to convey unexpected generosity in every project.
Dande-lier – a pavilion designed for the Marina Bay waterfront promenade in Singapore uses PVC pipes and translucent umbrellas to form a reciprocal dome – reimagining everyday items as architectural components. The result is an ethereal shelter, referential of the commonly seen umbrella in Singapore and resembling a dandelion from afar. At night the project becomes a chandelier, lit up in an array of colors.
Quirky, innovative and visceral, Get High without Drugs was awarded first place in the fabrication category at this year’s International FAB FEST* in London.
Mollusk-like and mysterious from the outside, the form of the pavilion emerges from the combination of a zonohedron and a dome. Seventy-two hexagonal surfaces were formulated into fold-able nets that could then be digitally fabricated from flat-sheets and assembled into load-bearing modules. A puzzle-like routine drove the assembly of the modules into the pavilion’s dome-like form.
Are the concrete buildings we build actually a sign of architectural progress? Defunct housing projects abandoned shopping malls, and short-sighted urban projects are more often than not doomed to a lifetime of emptiness after they have served their purpose. Their concrete remains and transforms into a lingering reminder of what was once a symbol of modern ambition. Stadiums and their legacies, in particular, come under high scrutiny of how their giant structures get used after the games are over, with few Olympic stadiums making successful transitions into everyday life. With a new approach to sustainability, the Shell Mycelium pavilion is part of a manifesto towards a more critical take on building. Say the designers on their position: “We criticize these unconscious political choices, with living buildings, that arise from nature and return to nature, as though they never existed.”
The Shell Mycelium Pavillion is a collaboration between BEETLES 3.3 and Yassin Areddia Designs and offers an alternative to conscious design through temporary structures. Located at the MAP Project space at the Dutch Warehouse, the pavillion formed part of the Kochi Muziris Biennale 2016 Collateral in India.
Developed by researchers and students from the Faculty of Architecture at HKU and supported by Sino Group, the 'Ceramic Constellation Pavilion' is built on a wooden structure that supports a series of "walls" formed by about 2,000 clay bricks. Each of these individual components is unique and has been manufactured using robotic technology and 3D printing, allowing to generate different types of transparency and opacity in their different faces.
London’s first Antepavillion officially opened to the public last weekend, kicking off an annual series of experimental structures set to explore alternative ways of living in the city. Designed and built by emerging studio PUP Architects, the proposal beat out 128 other entries as the winner of a competition held by the Architecture Foundation. Calling for proposals that engaged with issues of sustainability and recycling, PUP's design, dubbed H-VAC is built using prefab elements made in-house by a team of volunteers. The pavilion's tongue-in-cheek appearance resembling an air duct is a playful subversion of planning legislation, exploiting loopholes for mechanical rooftop equipment to be built without planning permission.
A team of architects from Florence, Italy have won CAMBOO’s bamboo design competition showcasing the material for its strong and sustainable construction qualities. Held in Phnom Penh, Cambodia, the CAMBOO festival sought to find an innovative design for a landmark pavilion as a centerpiece during the event. Architects Roberto Bologna, Fernando Barth, Chiara Moretti and Denny Pagliai beat out 125 entries with their winning “Hyperbamboo” pavilion, which was chosen for its “intelligent and well thought out use of bamboo as a construction material.”
Set in a valley located 45 minutes west of Santiago de Chile, an elementary timber shed by Josep Ferrando and Diego Baloian seeks to unhinge the division between vertical and horizontal architectural elements. The scheme is the result of a private commission to build a wooden shed on a family-owned plot in the town of Curacaví, halfway between the Chilean capital and the coastal town of Valparaíso.
Drawing heavy inspiration from vernacular canopies which historically dotted the landscape of rural Chile, the scheme seeks to create a central family meeting point amongst a vast 2 hectare plot.
A vibrant pavilion has arrived to grace the boardwalks of California’s Santa Barbara waterfront. The pavilion entitled Runaway has been designed by SPORTS, an architecture and design collaboration of Greg Corso and Molly Hunker, recently selected as one of the Architectural League of New York’s emerging young practices for 2017. Blending a bright, colorful character with functional modernity, Runaway was installed on the Waterfront of Santa Barbara in March 2017, one of several locations the pavilion will travel to throughout the year.
