Construction continues on King Salman Park in Riyadh, a 16.9-square-kilometre public landscape taking shape on the grounds of the city's former airport. Led by Omrania as lead design consultant, in collaboration with Henning Larsen for master planning and urban design, the project reimagines the centrally located site as a large-scale green and cultural district. Conceived as a new civic core for the capital, the park combines ecological restoration, public programming, and mixed-use development. Initial phases are expected to open in late 2026, with substantial completion targeted for 2027, following a phased construction schedule currently underway.

Heritage sites constitute complex spatial archives in which architecture, history, and collective memory converge. They encompass a wide spectrum of contexts—from archaeological remains, ancient and historic townscapes, UNESCO-listed landscapes, to early modern civic structures and industrial infrastructures. Yet these environments confront challenges: climate change, urban transformation, disaster, shifting social needs, and the gradual erosion of material fabric. Revitalization and restoration projects respond to these conditions by positioning architectural and spatial practice as an active mediator between preservation and the contemporary topologies.

The third edition of the Diriyah Contemporary Art Biennale opened on January 30, 2026, and will remain on view through May 2, 2026, in Riyadh, Saudi Arabia. Organized by the Diriyah Biennale Foundation, the Biennale takes place at JAX District, a former industrial area in Diriyah near the UNESCO World Heritage Site of At-Turaif. Titled "في الحِلّ والترحال" / In Interludes and Transitions, the exhibition is led by Co-Artistic Directors Nora Razian and Sabih Ahmed, while Milan-based architect Sammy Zarka contributed as the Associate Architect and Exhibition Designer. The exhibition scenography is designed by Formafantasma, and the event brings together more than 65 artists from over 37 countries, including more than 25 newly commissioned works.

Once a Najdi settlement defined by mudbrick walls and courtyard houses, Riyadh has undergone one of the most radical urban transformations of the 20th and 21st centuries. The discovery of oil reserves, the consolidation of political power, and the rapid expansion of infrastructure reshaped the city from a regional capital into a sprawling metropolis almost within a single generation. As a result, Riyadh's urban fabric is marked by discontinuities, fragments of vernacular architecture coexist with mid-century institutional modernism, and a rapidly evolving contemporary skyline.

In a global landscape marked by accelerated change, 2025 emerged as a decisive year for architecture—not only because of the major events that animated the international circuit, but above all because of the voices that stood out within them. From the Venice Architecture Biennale to Expo Osaka, pavilions and installations from the Global South ceased to function as mere exhibition gestures and instead asserted themselves as territories of memory, resistance, and imagination, articulating narratives that expand the horizons of contemporary architectural debate.

OODA announces the House of Nassr, a new integrated sports complex designed for Al Nassr FC in Riyadh, Saudi Arabia. Planned as a comprehensive facility supporting both athletic performance and club operations, the project brings together a high-performance training centre, administrative and media spaces, athlete support facilities, and social areas, with a hotel scheduled for a second phase of development. The complex occupies an area of approximately 4,000 square meters. While the overall project remains ongoing, the first phase has been completed in 2025, marking OODA's first realized project in Saudi Arabia.

Noor Riyadh 2025 brought large-scale light installations to public sites across the Saudi Arabian capital, temporarily transforming transit hubs, historic districts, and significant landmarks into illuminated urban environments. From November 20 to December 6, 2025, Riyadh became a citywide gallery of light, motion, and shifting perception. The festival's fifth edition featured 60 artworks by 59 artists from 24 countries, including more than 35 new commissions, responding to the theme "In the Blink of an Eye." Through light as both medium and concept, the installations reinterpreted the capital's rapidly evolving architectural landscape and reflected how perception shifts in spaces shaped by heritage and ambitious urban development.

Infrastructure has long defined the backbone of cities by linking people, landscapes, and economies through systems that often go unnoticed until they fail. Today, as global challenges demand more adaptive and human-centered responses, architects are rethinking what infrastructure can be: not just a framework for movement and utility, but a catalyst for ecological restoration, cultural continuity, and civic imagination. The following unbuilt projects, submitted by the ArchDaily community, explore this expanded role of infrastructure, where airports, bridges, industrial parks, and pedestrian networks become architectural expressions of connection and care.
