Set within the historic district of Diriyah, widely recognized as the birthplace of the first Saudi state, the Grand Mosque by X Architects forms part of the ongoing transformation of the area into a major cultural destination in Riyadh. Envisioned within the Diriyah Gate II development, the project is positioned at the intersection of heritage preservation and large-scale urban redevelopment, contributing to a broader master plan that includes museums, civic institutions, residential neighborhoods, and public spaces. Within this context, the mosque is conceived not only as a place of worship but also as an urban anchor embedded in the evolving fabric of the district.

More than three decades after previously hosting the event, Barcelona is set to welcome the UIA World Congress of Architects 2026 Barcelona (UIA2026BCN), bringing the global architectural community back to the city between 28 June and 2 July 2026. Organized under the theme "Becoming. Architectures for a Planet in Transition," the Congress is expected to gather approximately 10,000 participants from over 130 countries, including practitioners, researchers, and students. Rather than being confined to a single venue, the event will unfold across multiple locations along the Mediterranean seafront, among them the Three Chimneys complex, positioning the city itself as an active platform for exchange, discussion, and public programming.

As housing shortages and affordability challenges intensify across global cities, this week's architectural discourse centers on how design, policy, and adaptive strategies intersect to shape the future of urban living. Initiatives range from grassroots movements and legislative reforms aimed at expanding access to housing to innovative models that rethink ownership, development, and community engagement. At the same time, architects are reimagining existing structures and districts, transforming underused offices, historic landmarks, and unfinished buildings into mixed-use, culturally significant, or publicly accessible spaces. Across scales, these stories illustrate how architecture negotiates scarcity, value, and social priorities, demonstrating its capacity not only to produce new buildings but also to recalibrate urban environments in ways that balance heritage, sustainability, and human experience.

The southern ambulatory of the Colosseum in Rome has been restored through an intervention led by Stefano Boeri Interiors, a multidisciplinary studio founded by architects Stefano Boeri and Giorgio Donà, for the Parco Archeologico del Colosseo, focusing on the reconstruction of the crepidine and the repaving of missing sections to reinstate the monument's original ground levels and improve the legibility of its southern perimeter. The project builds on an archaeological investigation campaign that informed both the geometric definition of the intervention and its material articulation.

CRA–Carlo Ratti Associati has been selected to design the Buzzi Heritage cultural center in Casale Monferrato, Italy. The proposal introduces a 100-meter-long suspended truss that links two former educational buildings, consolidating archival, research, and cultural functions within a single structure. The project also marks the first real-world application of a patented structural system developed through research by Carlo Ratti Associati in partnership with Maestro Technologies. Positioned above a system of open spaces, the intervention reconfigures the site as a publicly accessible cultural complex while maintaining a clear distinction between built and landscaped areas.

Located within the Parque Tecnológico de Brasília, the World Trade Center Biotic is a mixed-use development designed by Brazilian studio Architects Office as part of the district's broader urban expansion. The project is part of the master plan developed in 2020 by Carlo Ratti Associati and is currently being developed. Conceived as a multi-program complex, the proposal brings together offices, residential units, a hotel, retail spaces, and shared facilities within a single urban framework. The project occupies a site of approximately 70,000 square meters and is planned to reach about 180,000 square meters of built area, with an estimated 150,000 square meters expected to be completed by 2030.

BT Tower, one of London's most recognizable postwar landmarks, is set to be converted into a hotel. London-based architecture practice Orms has been appointed to lead the redevelopment following the acquisition of the Grade II–listed tower by the American hospitality company MCR Hotels in early 2024. The project was initially expected to be led by Heatherwick Studio, though the practice is no longer involved; Orms will now advance the scheme and is expected to present its initial proposals during a first round of public consultations scheduled for May. Construction cannot begin until the decommissioning and removal of telecommunications equipment by BT Group, a process currently expected to conclude around 2030.

Located in Istanbul, Türkiye, an 84-hectare neighborhood is currently under development in the Riva area of Beykoz along the city's Black Sea coast. The master plan has been developed by an international design team including Snøhetta, Bjarke Ingels Group, and MVRDV, alongside local practices KEYM, DB Architects, Rasa, and Bilgin Architects. Known as Ion Riva, the project is conceived as a landscape-led residential community that integrates housing, cultural facilities, and public programs within an ecological framework shaped by the meeting of forest, river, and sea. The first phase of the development, which has received planning permission and is currently under construction, will deliver 969 homes designed for approximately 3,000 residents, with the first completed residences expected to be occupied in 2027.

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.

Architecture this week reflects the intersections of legacy, authorship, and social responsibility, as practices navigate questions of identity, recognition, and public engagement. Legal rulings, major competition shortlists, and large-scale urban proposals illustrate how architecture continues to operate across cultural, institutional, and environmental arenas. From sustainability-driven landmarks and transformative waterfront developments to iconic commercial towers, projects demonstrate approaches to ecological strategies and public programming. At the same time, global observances such as World Hearing Day highlight how spatial design shapes inclusion and accessibility, reminding the profession that the built environment can influence participation, learning, and well-being for diverse communities.

Hariri Pontarini Architects and Snøhetta have been selected to design the new Ontario Science Centre in Toronto. Announced in February 2026, the 400,000-square-foot facility will anchor the site's ongoing transformation through a 220,000-square-foot building defined by a series of scalloped, modular volumes. A central component of the proposal is the physical integration of the existing Pods and the historic Cinesphere via elevated connections and a continuous public promenade. Construction is expected to begin in Spring 2026, with completion anticipated in 2029 as part of a broader waterfront redevelopment strategy.
