At the end of each edition of the Architecture Biennale, far from the public eye, tons of exhibition materials are transported across Venice in handcarts and boats. Only a small portion of these materials is reused. The main obstacles are the limited storage space in Venice and the high logistical costs—recurring challenges for circular architecture. As a result, most of the waste ends up in landfills or nearby recycling centers. But this scenario is beginning to change. In response to growing environmental concerns, architects are developing strategies to make reuse more viable. These efforts go beyond architectural and construction decisions—they also involve logistics and international trade.
Søren Pihlmann is the curator of the Danish Pavilion at the 2025 Venice Architecture Biennale. The exhibition, commissioned by the Danish Architecture Center, is titled Build of Site, and focuses on exploring sustainable architectural practices through the lens of reuse and resourcefulness. Pihlmann's proposal transforms the existing Danish Pavilion, located within a historic building complex in the Biennale's Giardini, into an active exhibition space for material experimentation. The installation highlights techniques that incorporate recycled and bio-based elements. The Pavilion offers visitors the opportunity to observe ongoing experimental processes, witnessing how building resources are creatively reimagined for new uses. In this on-site interview, ArchDaily editors spoke with the curator about the ideas behind the project and the challenges its execution represents.
The 19th edition of the Venice Architecture Biennale officially opened to the public on May 10, becoming a significant international platform for exploring the current state of global architecture and sparking conversations about the challenges the discipline faces today—both shared and specific to each territory. This year’s theme, "Intelligens. Natural. Artificial. Collective," proposed by general curator and Italian architect Carlo Ratti, invites reflection on architecture’s interconnection with other fields—such as art, artificial intelligence, and technology—while also emphasizing the importance of territories, landscapes, and, above all, the people who collectively shape our built environment.
Qatar has announced that architect Lina Ghotmeh, founder and principal of the Paris-based studio Lina Ghotmeh — Architecture, has been selected to design its permanent national pavilion in the Giardini della Biennale, the historic venue of La Biennale di Venezia since 1895. The new building will be on a site adjacent to the Book Pavilion and commissioned by H.E. Sheikha Al Mayassa on behalf of the State of Qatar. With this addition, Qatar becomes one of only 31 countries with a permanent pavilion in the Giardini, joining a select group of nations with dedicated exhibition spaces. Only two new national pavilions have been inaugurated there in the past 50 years: Australia in 1988 and the Republic of Korea in 1996. Lina Ghotmeh's new Qatar Pavilion will serve as a lasting platform for showcasing the country's artistic and architectural contributions, with rotating exhibitions presented during each edition of the Biennale.
Built on a cluster of 118 small islands in the shallow Venetian Lagoon, the city of Venice, Italy, has captivated the imagination of architects and tourists alike. The area has been inhabited since ancient times, becoming a major financial and maritime power during the Middle Ages and Renaissance, as proven through the rich architecture that characterizes the city to this day. With influences from the Byzantine, Gothic, and Renaissance styles, the city represents a palimpsest of architectural narratives, overlapping and influencing each other. In recent years, Venice has become a major attraction for architects drawn to the La Biennale di Venezia, the most important Architectural Exhibition featuring national pavilions, exhibitions, and events to explore new concepts and architectural innovations.
Beyond the Biennale, Venice itself is an open-air museum for architecture lovers. While the city is best known for its historical buildings, Modernist and contemporary interventions add a new layer of interest, with many contemporary architects working with the historical fabric, like OMA's intervention and rehabilitation of Fondaco dei Tedeschi, or David Chipperfield's renovation of Procuratie Vecchie, one of the buildings that define Piazza San Marco. In addition to what the city has to offer, the site of the Venice Biennale is also marked by interventions by famous architects such as Carlo Scarpa, Sverre Fehn, and Alvar Aalto, made permanent due to their outstanding qualities.
The Unfolding Pavilion is a recurring exhibition and editorial project by Daniel Tudor Munteanu and Davide Tommaso Ferrando that aims to highlight previously inaccessible but architecturally significant spaces. Now in its fourth edition, the exhibition is dedicated to the Giardini della Biennale, the Venetian garden that became the main location for one of the most important architecture exhibitions worldwide, the Venice Biennale. Through a series of site-specific interventions and photographs by Laurian Ghinițoiu, the Unfolding Pavilion #OPENGIARDINI set out to explore the paradoxical state of this public space that is not publicly accessible.
Over the past couple of weeks, we have seen how countries have responded to “How will we live together” in 115 different ways. Some studied the environment and how to sustain it, while others explored how they can create a safe space for refugees and citizens to coexist. In this roundup, we are concluding the list of national pavilions displayed at the 17th International Architecture Exhibition – La Biennale di Venezia, and highlighting how they answered curator Hashim Sarkis' question.
"When we enter the restroom, we are never alone. Instead, we are entangled in a network of bodies, infrastructures, ecosystems, cultural norms, and regulations". Although restrooms are often overlooked facilities that cater to the needs of individuals, they are, however, spaces where gender, religion, race, hygiene, health, and the economy are defined and expressed. For the 17th International Architecture Exhibition at La Biennale di Venezia, Matilde Cassani, Ignacio G. Galán, Iván L. Munuera, and Joel Sanders designed two pavilions that exhibit how restrooms are political architectures, serving as battlegrounds for the world's disputes.
The Hungarian Pavilion at the 17th Venice Biennale explores the often challenging socialist architecture and looks at how this heritage could be reconsidered and given a new future. Titled Othernity – Reconditioning our Modern Heritage, the exhibition curated by Dániel Kovács presents twelve iconic modern buildings of Budapest and the visions of twelve architecture practices from Central and Eastern Europe for their reconditioning. The Hungarian Pavilion's project looks into how architecture can build on its past to foster resilience, sustainability and strong cultural identities.

The city of Venice has been caught in a tug of war between progress and traditionalism for many years, and particularly since the construction of a railroad viaduct in 1846 linked the island city to the Italian mainland for the first time in its history.[1] Over a century later, the Venetian government commissioned Louis Kahn to design a new Palazzo dei Congressi for the city; his proposal, while paying respect to the histories of both the Republic of Venice and a unified Italy, could not escape similar controversy.
