Transformation of the Saint-Vincent-de-Paul Hospital in Paris into housing

By Lacaton & Vassal

French architects Anne Lacaton and Jean-Philippe Vassal have won the most important awards in the sector – the Pritzker and the Mies van der Rohe – with a philosophy based on a rigorous economy of means and the power of renovations. In this case, they transform a 1950s hospital into 134 homes, 66 of which are for sale, 33 for social rent, and 35 for rent. To make this possible, they add up to four floors to the existing building. The project, which includes the collaboration of their protégé Gaëtan Redelsperger, includes 2,600 m2 of commercial space, out of a total of 12,490 m2.

The Blue Ocean Dome.

Blue Ocean Dome

By Shigeru Ban

A new demonstration of the talent of the Japanese Shigeru Ban in innovation with materials and the desire to reduce their environmental impact. This work, built for the Osaka Universal Exposition of 2025, consists of a complex of three domes built with paper tubes, laminated bamboo, and, for the first time in a large structure, carbon fiber reinforced plastic (CFRP). "CFRP has been used in aircraft and automobile bodies, but not yet as a main structure in architecture. Since the structure weighs less than the earth that would need to be excavated for the foundations, we managed to eliminate the need for piles," explains Shigeru Ban. This made it possible to install the building on a site with low resistance and made it easier to relocate the building. Shigeru Ban, who won the Pritzker Prize in 2014, is also known for emergency buildings in natural disaster contexts with these same materials.

D'Amateur Architecture Studio

Amateur Architecture Studio is formed by architect Wang Shu, the only Chinese Pritzker winner, and his wife and partner, Lu Wenyu. They are known for how, instead of being carried away by the wave of China's modernization based on the destruction of historical fabrics, they create contemporary, and at the same time, timeless and rooted architecture. One of the most extreme cases of their vision is the Ningbo History Museum, built with the remains of the buildings that were there. They have maintained the same idea in one of their most recent works, the Lin'an History Museum, where they integrated pieces of the cultivated land of the village where it stands and fragmented the building into different volumes so that it would resemble the houses of a village and not "a large container".

The Limbo Museum, in Accra (Ghana), is driven by the Limbo Accra studio, founded by Dominique Petit-Frère and Emil Grip. They are focused on "unlocking the potential of unfinished buildings in West Africa and beyond," experimenting with the repair and transformation of abandoned buildings. The Limbo Museum is located within the skeleton of a brutalist building and has been operating since October 31, 2025, as a creative laboratory for architects, artists, and designers. "We adopt an intuitive and future-ready approach to experience, material, and space," explain Dominique Petit-Frère and Emil Grip.

London Sky Bubble

By Smiljan Radic

The Chilean Smiljan Radic has won the Pritzker Prize 2026 for works that are "at the crossroads of uncertainty, material experimentation and cultural memory", as the jury said. "His buildings seem temporary, unstable or deliberately unfinished, almost about to disappear, and yet they offer a structured, optimistic and discreetly cheerful refuge that welcomes vulnerability as an intrinsic condition of lived experience", the jury added. Among his most recent works is the London Sky Bubble, in Tobacco Dock, which in 2022 was the setting for the first fashion show of the Alexander McQueen brand after the covid pandemic: it is an inflatable cloud that recalls utopian architectures of the 60s and 70s. The generator that kept it running was powered by hydrotreated vegetable oil, a renewable alternative to diesel made from fats, food waste and agricultural residues.

Zaishui Art Museum.

Zaishui Art Museum

By Junya Ishigami

In one of his most well-known statements, the Japanese architect Junya Ishigami points out that he wants to create architecture that is like "a new nature". Ishigami is known for his bold vision: "The architecture we have is mainly based on history and knowledge of the past, even if we use the latest technologies. We must always rethink the meaning of architecture in our current time and its purpose. Anything can become architecture. That's why we have to rethink what architecture is today and temporarily forget the past to recreate new fundamental bases suitable for the present." In the case of the Zaishui Art Museum, in Rizhao (China), it is a kilometer-long walkway that crosses an artificial lake, with the aim of integrating the building into the landscape. In fact, water enters the building. In addition to exhibition halls, the space includes an information center and commercial areas and functions as the iconic entrance to a new district of the city.

Khudi Bari Modular Structures

By Marina Tabassum 

Khudi Bari, "small house" in Bengali, is a modular solution to provide dignified housing for people who are in a situation of forced displacement, and it has been replicated in different places in Bangladesh as self-built housing. The Khudi Bari is a structure made of bamboo and steel connectors. It is lightweight and, at the same time, resistant. It is designed so that three people can assemble it in just three days with simple tools and dismantle it in a few hours. The foundations do not need to be deep. The housing is divided into two levels: a ground floor for social and private spaces, and an upper floor that serves as a bedroom and shelter in case of floods. The roofs are made of corrugated sheet metal, which facilitates transport and maintenance, and the facades can be built with local materials, which reinforces the link with the environment. For this work, the Bangladeshi Marina Tabassum won the Aga Khan Award for Architecture in 2025.

From Cooking Sections

Cooking Sections is a London-based studio formed by Spaniard Daniel Fernández Pascual and Israeli Alon Schwabe. They come from the world of architecture, but their distinctive feature is a multidisciplinary environmental research often focused on food. These investigations allow them to reveal "industrialization and extraction practices that are transforming the planet". Their work takes various forms, such as the installation they presented at the Botín Centre in Santander last autumn, The Lost Waves. The disappearance of the Mundaka wave was the starting point for reflecting on the devastation in the marine environment. "There are many, many waves threatened with extinction, due to the construction of new ports, the dredging of new channels, and new forms of fishing that increasingly alter the seabed. It is about becoming aware that the surface and the seabed are connected. And that steps must be taken to protect the waves," they warn.

From a Certain Study

The Barcelona-based studio Cierto Estudio, founded by Marta Benedicto, Ivet Gasol, Carlota de Gispert, Anna Llonch, Lucia Millet, and Clara Vidal, is known for some emblematic works in Barcelona in recent years, such as the green axis of Consell de Cent street, and especially for its work in the field of housing, where a housing block at Illa Glòries stands out. The UIA has recognized it with the first UIA Young Architects award for its contribution to contemporary architectural practice. For the jury, Cierto Estudio embodies "a model of shared authorship that reinforces its commitment to inclusive processes and to a practice founded on common values." "The studio stands out for its commitment to architecture as a tool to improve the living conditions of the majority, with special attention to housing. In both public and private commissions, their work reflects a coherent design approach that seeks to improve living conditions while maintaining a careful balance between architectural quality and broader social impact," says the jury. Among those awarded by the UIA this year is the Fetdeterra studio.

Project by Andrés Jaque's Shift Landmark competition.

Andrés Jaque / Office for Political Innovation

The Madrid-born architect Andrés Jaque, founder of the Office for Political Innovation and dean of Columbia's architecture school, is one of the five finalists for the Shift Landmark competition, an urban laboratory for innovation and climate adaptation to be built in Rotterdam's new Waterkant district. It is a complex of up to 30,000 m² that will include an immersive experience of 10,000 m², a hotel, a conference center, and gastronomic spaces. The project starts in Rotterdam because 55% of the Dutch territory is vulnerable to floods and a large part of the city is below sea level, which is why it is considered a global symbol of resilience. Jaque's project is titled Planetary landmark for the climate age" (Planetary monument of the climate age), and is conceived as "an operational section of the planet of transformation", where there would be immersive experiences capable of activating "new social behaviors".

The UIA congress, from June 28 to July 2, will include over 100 sessions, a large 4,000 m² central exhibition, and more than 70 tours of Barcelona and its surroundings, connecting the content with the territory and opening exceptional spaces for the occasion. The main venues will be the Barcelona International Convention Centre (CCIB), the Disseny Hub Barcelona, and the Tres Xemeneies complex in Sant Adrià de Besòs, while the Sagrada Família will host the Gold Medal award ceremony and the UIA triennial prizes.At the presentation of the program, held at the COAC headquarters, the mayor of Barcelona, Jaume Collboni, emphasized that World Capital of Architecture 2026 “reconnects architecture with citizens,” and that the Congress “will once again place Barcelona at the center of international debate.”The Minister of Territory, Housing, and Ecological Transition, Sílvia Paneque, championed the role of architecture in building a society “fairer, more sustainable, more human,” thirty years after the first UIA congress in Barcelona. She defined architecture as “an act of transformation” that also shapes the framework for policy action, and summarized the major challenges to be debated: architecture designed for humans and for ecological systems and biodiversity; building without destroying, prioritizing reuse and rehabilitation; linking transformations to the roots and identity of the territory; understanding public space as a humanist right; and analyzing the impact of permanent change – especially digitalization and artificial intelligence – on the urban fabric. Paneque also insisted on the “biographical interconnection” between the city and the people who inhabit it, concluding that “modernity and urbanity are the most human possibilities for coexistence in freedom for human beings.”On the other hand, the Vice-President of the International Union of Architects and of the Congress, Teresa Táboas, remarked that the congress “is open not only to architects, but to everyone,” because the transitions affecting the planet “do not respect the boundaries of any discipline.” She described the congress as a “polyphony of perspectives, geographies, disciplines” seeking a common melody and defended the “miracle” of UIA congresses, capable of making architecture “stop talking to itself and become listening, a meeting, to create a symphony.” For Táboas, “the world is in transition; this is the only certainty,” and what is done with this transition – how it is thought, built, and inhabited – will also depend on what emerges from this congress in Barcelona in the summer of 2026.
