Initial sketches in notebooks and tracing paper, conceptual diagrams, perspectives, physical models, and massing studies capture the architectural imagination. But they represent only the beginning of the practice. The real challenge is translating ideas into buildable systems. Every wall, junction, and assembly must be resolved in detail, with systems working together in a way that allows the project to be built as intended. This is where most of the effort, complexity, and risk are concentrated, and where projects are ultimately resolved or begin to stumble.

It is in this context that the Design Development (DD) and Construction Documentation (CD) take place, when the project must address the full weight of coordination, components, performance, and constructability. While schematic design defines spatial and formal directions, DD and CD demand answers to a different set of questions: how do systems come together? How is performance maintained at transitions? Which products, tolerances, and sequences will allow the project to hold together as it moves from model to construction?

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.

The Pan-African Biennale (PAB) is a platform for discussion and exchange on architecture, bringing together, for the first time, all countries in the African continent. To highlight African contributions to the field, it seeks to shift the narrative from one of fragility to one of resilience by raising awareness of the continent's traditions, design, culture, and collective memory. The inaugural one-week event is scheduled to take place in Nairobi, Kenya, launching on September 7, 2026. As the first architecture biennale of its kind on the continent and a highly anticipated event, the opening week will feature exhibitions, installations, keynote dialogues, and public events across the city and other satellite locations. Curated by Somali-Italian architect Omar Degan, the biennale aims to shift architectural discourse by expanding contributions from studios representing all 54 African nations, exhibiting work rooted in local contexts, materials, and cultural narratives.

Collective housing is a hallmark of Europe. The 2nd edition of the award is looking for collective housing projects to highlight their social impact and the policy frameworks that support them. Submissions are free and open until 30 April.

Post-industrial modernity generated a wide range of collective housing models that left a lasting mark on European cities and architectural history: from the Hofs of Vienna and the Weissenhof Siedlung to Le Corbusier's Unité d'habitation and the works presented at Berlin's Interbau.

The excesses of the modern movement cast a long shadow over social housing – a stigma that post-modernity failed to dispel. Yet since the turn of the millennium, new forms of collective housing have re-emerged, reconnecting with welfare-state ideals amid pressures from urbanization, property market tensions and ecological urgency.
