The European Commission launched Horizon Europe in 2021 as its most ambitious research and innovation program to date, committing over 95 billion euros to accelerate scientific discovery and address the defining challenges in European cities. Among the initiatives that Horizon Europe funds is ReGreeneration, a transnational consortium uniting nine cities, their governing bodies, leading research institutions, and technology partners in the region.

In highly-curated environments such as Disneyland Paris, architecture operates under a different set of expectations. Buildings are not only required to perform, they must also communicate, often instantly. Within this context, the facade becomes a visual marker that can serve as a threshold, mediating light, air, and perception. One strategy that has gained traction in this setting is the use of semi-opaque envelope systems. Neither fully transparent nor entirely enclosed, these facade systems introduce depth and variability.
Paris's 19th arrondissement Parc de la Villette is undergoing a major transformation, combining a newly opened urban farm with restored biodiversity as part of a strategy to adapt the 55.5-hectare park to climate change. Masterplanned by Bernard Tschumi in 1982 and opened to the public in 1987, the park stands as a landmark of European modernism in public space design, breaking from the traditional concept of the metropolitan park. With a 15,000-square-meter extension, this major green lung in northeast Paris is reimagining its lawns as a living laboratory for environmental education, where animals, plants, and humans coexist. The extensive renovation follows the addition of Tschumi's HyperTent in 2022, a hyperbolic paraboloid structure functioning as a new ticket booth on the podium of Folie L4, and marks the park's most significant transformation since its inauguration.
Art Paris will return to the Grand Palais from 9-12 April 2026, marking the 28th edition of the fair at the recently renovated landmark. Reopened following its most extensive restoration in over a century, the 77,000-square-meter building, transformed under the direction of Chatillon Architectes, now accommodates large-scale cultural events across its nave and balcony spaces. Bringing together approximately 165 galleries from around twenty countries, the fair is structured around two curatorial themes, language and reparation, presented within an updated spatial framework defined by improved circulation and expanded exhibition areas.
Today's housing crisis is a global phenomenon that can be broadly divided into two major problems: a shortage of residential buildings and barriers to accessing those that already exist. The deficit is real and concrete when it comes to what the UN calls "adequate housing for all." According to UN-Habitat, an estimated 96,000 new housing units would need to be built per day to meet population needs by 2030. Climate change and forced migration are broadening the gap. But 2.8 billion people worldwide, representing nearly 40% of the global population, lack access to stable shelter, secure land, and basic sanitation services not only because of underproduction, but also due to an economic barrier: an affordability crisis. As demand grows and prices rise, housing, now increasingly functioning as a form of social security, becomes a target for rental income and real estate speculation. As adequate housing is a human right, pressure on governments and private entities is increasing worldwide to limit speculation and ensure fair access to existing dwellings. Below, we present four examples of initiatives in Spain, Australia, France, and the United States that aim to urgently expand housing access while limiting speculation.
RSHP has won a competition to redevelop the Rives-Défense site in La Défense, the business district of Paris. Announced during MIPIM, the project envisions the transformation of an 8-hectare site at the western edge of the district into a low-carbonmixed-use neighborhood. Commissioned by Paris La Défense, the proposal is developed by a multidisciplinary team led by RSHP and including Atelier SOIL as co-architect and urban planner, Altitude 35 as landscape architect, Arcadis as engineering consultant, as well as Atelier Franck Boutté, Urban Eco, and Mobius.
The public observation deck at the top of the Tour Montparnasse, long considered one of the most debated additions to the Parisian skyline, is set to close on March 31, 2026, ahead of a major redevelopment of the tower and its surrounding complex. Completed in 1973, the 210-meter structure has remained the only skyscraper within central Paris for decades, frequently criticized for its scale and contrast with the historic cityscape. The closure of the Paris Montparnasse Observatory marks the beginning of a multi-year transformation aimed at modernizing the tower while rethinking its relationship with the surrounding Montparnasse district.

On February 20, Renzo Piano Building Workshop announced that the building permit for the Hôpital Universitaire Saint-Ouen Grand Paris Nord (HUSOGPN) has been officially granted. The project is a state initiative responding to rapid population growth, increasing demand for care, and evolving technical standards with a "next-generation" hospital in Saint-Ouen-sur-Seine, a commune in the northern suburbs of the French capital. The hospital will be located on the site of the former PSA factory, once an industrial engine of the region and now large and well-connected enough to host a program of rare scale: 986 beds and 288 day places, a workforce of over 5,500 professionals, and facilities equipped with contemporary technology for areas such as surgery and maternity. Envisioned as a "hospital-landscape," the building designed by RPBW in association with Brunet Saunier & Associés stands out for featuring a 1.3-hectare roof garden and an urban forest with over 1,000 trees.
On January 30, an exhibition entitled "Concours Beaubourg 1971: Une mutation de l'architecture" opened in Paris, showcasing archival material from the competition that resulted in the selection of the current Centre Pompidou, designed by Renzo Piano and Richard Rogers between 1969 and 1974. In view of the building's recent closure for renovation, approximately 100 archival documents, including some never before exhibited from the Centre Pompidou's collections (plans, drawings, photographs, models, etc.), are on display at the Académie d'Architecture at Place des Vosges until February 22, 2026. Co-produced by the Académie d'Architecture and the Centre Pompidou, with support from the École nationale supérieure d'architecture de Saint-Étienne, the exhibition presents alternative, imaginative, and sometimes unbuildable proposals for the building. It offers a review of a fertile period in architectural history, highlighting the lasting effects of the "Beaubourg competition" on the discipline and profession.

This week's news landscape brought together diverse approaches to built and cultural heritage, ranging from the design of a Museum of Jesus' Baptism at a UNESCO World Heritage Site in Jordan to major transformations of modern industrial sites and the development of major cultural districts. The World Monuments Fund's support for 21 locally led heritage projects foregrounds conservation strategies that reinforce the role of architecture in safeguarding both material and intangible heritage. Across this week's highlighted projects, adaptive reuse, landscape integration, and the reconfiguration of civic space emerge as recurrent strategies for extending the life and relevance of existing built environments. The projects also reflect broader contemporary concerns, including material research in timber construction, zero-waste urban installations, large-scale residential efficiency, and infrastructure upgrades linked to global events like the Olympic Games. Framing these developments within a wider territorial perspective, discussions on relocating capital cities worldwide offer an example of how geopolitical discourses continue to shape architecture, revealing the evolving relationship between the built environment and structures of power over time.
The recently inaugurated exhibition matière en résonance ("resonant matter") brings together a wide range of models and a curated selection of photographs to present sauerbruch hutton's ongoing exploration of timber. The exhibition starts from the premise that while the age of concrete defined the twentieth century, the early twenty-first century has seen a worldwide resurgence of timber, a much older building material. Timber is presented as offering "a different version of modernity" and as the subject of renewed interest that reawakens long-standing collective imaginaries. Over more than two decades, the Berlin-based architecture practice has explored the possibilities of timber construction, from façade elements to load-bearing structures and modular systems. The exhibition reflects the results of this sustained investigation, reinforcing both technical innovation and the embodied qualities of timber across a diverse range of European contexts. The exhibition will be on view from 3 to 28 February 2026 at the Galerie d'Architecture de Paris.

During a presentation to the press held at Paris City Hall on January 7, 2026, architect and Pritzker Prize laureate Renzo Piano released the first images of the transformation of Montparnasse's emblematic shopping center and CIT Tower into a pedestrian-focused district in Paris, France. The project, commissioned to Renzo Piano Building Workshop (RPBW) in 2022 by the co-owners of the commercial complex, proposes both a visual and functional transformation of the 1970s low-rise retail development into a more traversable space characterized by transparency and openness. The design was developed in parallel with the redevelopment of the Montparnasse Tower, led by Nouvelle AOM, to reshape the broader tertiary complex into a contemporary Parisian block oriented toward public life, environmental performance, and everyday use. The project reopens the site to the city, reconnecting streets and restoring continuity between Montparnasse and its surrounding neighborhoods through new public spaces.
From building codes to mobility restrictions and new diplomatic roles within city governments, climate policy is increasingly being shaped at the local level through a widening range of legislative and institutional tools. Cities as varied as Sydney, Boston, New York, Paris, Miami, and dozens across Latin America are adopting targeted strategies that reflect their distinct environmental pressures and governance structures. These initiatives range from all-electric and net-zero construction requirements, to traffic-control measures designed to curb the social costs of private vehicle use, to emerging forms of urban diplomacy that coordinate responses to rising temperatures and biodiversity loss. Together, these approaches illustrate how territorial management is evolving in response to the accelerating climate crisis, and how local governments are experimenting with regulation and collaboration to confront challenges that are at once global and deeply place-specific.
The opening of the new Fondation Cartier pour l'Art Contemporain in Paris last October sparked renewed questions around the role, form, and future of museums. As cultural institutions continue to proliferate worldwide in this digital era, the museum itself appears increasingly in need of redefinition. Rather than offering a single model or solution, Architecture for Culture: Rethinking Museums, written by architectural historian and curator Béatrice Grenier, argues for a more contextual and plural understanding of what a museum can be: an institution shaped by its environment, its public, and the specific cultural questions it seeks to address.
ArchDaily had the opportunity to discuss these ideas with the author against the backdrop of the Fondation Cartier's newly inaugurated home on Rue de Rivoli. Housed within a restored Haussmannian building that once accommodated the Grands Magasins du Louvre, the space has been radically reimagined by Jean Nouvel as a dynamic, transformable architecture.
