Designing with What Exists: Rieder’s HQ Expansion Turns Residual Materials into Facade Design

 | In Collaboration

What if industrial leftovers weren't waste, but the start of architectural design? At Rieder's headquarters in Maishofen, Austria, over 1,300 cubic meters of timber, 180 ceiling elements, and hundreds of upcycled glassfiber-reinforced concrete fragments come together in a building shaped as much by reuse as by planning. The new production hall, designed by Kessler² Architecture, treats material leftovers as a design resource. Developed as part of a long-term investment in sustainable manufacturing, the timber-concrete hybrid building introduces a facade technique that inverts conventional architectural workflows: instead of designing first and producing components afterward, the building envelope is generated from the material remnants already available on site establishing a new language for industrial architecture.

"Each Constraint Becomes More of an Opportunity": In Conversation With Holcim Award Winner THINK TANK architecture

The Zando Central Market redevelopment in Kinshasa, Democratic Republic of the Congo, designed by THINK TANK architecture, has been selected among the 20 winning projects of the 2025 Holcim Foundation Awards in the Middle East and Africa region. Originally designed for 3,500 traders and now accommodating more than 20,000 vendors, the market has long operated under conditions of severe overcrowding and infrastructural strain. The project stands out for its large-scale public ambition, its reliance on locally available materials and skills, and its capacity to accommodate both formal and informal economies within a rapidly transforming urban context.

UIA 2030 Award Announces Regional Finalists of Its Third Cycle Across Five Global Regions

The International Union of Architects (UIA), in partnership with UN-Habitat, has released the Stage 1 results of the third cycle of the UIA 2030 Award, identifying the projects selected as Regional Finalists. The shortlisted entries were drawn from submissions across the UIA's five global regions and will advance to the second stage of evaluation. Established in alignment with the UN 2030 Agenda for Sustainable Development, the award framework positions the built environment within broader discussions on sustainable urban development and global policy objectives.

Circular Composites: Designing for a Sustainable Future

 | In Collaboration

The pursuit of stronger, lighter, and more durable materials has guided architecture long before polymers or carbon fibers existed. One of the earliest large-scale examples of composite materials can be found in the Great Wall of China, where stone, clay bricks, and organic fibers such as reeds and willow branches were blended to create a resilient and lasting structure. These early techniques reveal a timeless intuition: distinct materials, when combined thoughtfully, produce properties unattainable by any single element. As the construction sector faces urgent ecological pressures, this intuition is being revisited through the lens of sustainability, with architects and engineers exploring bio-based, recycled, and hybrid composites designed not only for performance but also for circularity and environmental responsibility.

"Full of People and Alive Once Again": In Conversation With Holcim Award Grand Prize Winner RIWAQ – Centre for Architectural Conservation

Qalandiya: the Green Historic Maze, developed by RIWAQ – Centre for Architectural Conservation, has been awarded the Grand Prize at the Holcim Foundation Awards 2025, recognizing its sensitive and deeply contextual approach to heritage conservation in Palestine, selected among the 20 winners of this year's edition. Located in Qalandiya, north of Jerusalem, the project reactivates a historic village center long affected by political fragmentation, neglect, and spatial disconnection. Through an incremental rehabilitation strategy, the project restores deteriorated structures using traditional knowledge, local stone masonry, and native materials, transforming abandoned fabric into active public spaces while reinforcing environmental resilience through passive climate strategies and landscape-based infrastructure.

3XN’s Sydney Fish Market to Open as Blackwattle Bay’s First Completed Project

Set to open on January 19, 2026, the Sydney Fish Market marks the first completed project within the broader renewal of Blackwattle Bay on Sydney's inner harbour. Designed by 3XN in collaboration with BVN and Aspect Studios, and delivered by Multiplex, the purpose-built facility replaces the former market with a contemporary structure that combines an operating wholesale fish market with retail, dining, and publicly accessible waterfront spaces. Positioned approximately one mile southwest of Sydney's central business district, the project reframes one of the world's largest fish markets by volume as both working infrastructure and a civic destination.

"Learning in Contact With Nature": In Conversation With 2025 Holcim Award Winner Urko Sánchez Architects

Subscriber Access | 

The Waldorf School Nairobi, designed by Urko Sánchez Architects, has been selected among the 20 winning projects of the 2025 Holcim Foundation Awards, which recognize contributions to sustainable design and construction worldwide. Located within a forested site in Nairobi, the project was awarded in the Middle East and Africa region, acknowledging its sensitive response to site conditions, educational needs, and local culture. Developed in close dialogue with its surroundings and community, the school explores low-impact construction methods, the use of locally sourced materials, and participatory design processes.

New Life for Old Spaces: Buildner Announces Results of Its First Annual Re-Form Competition

 | Sponsored Content

Buildner has announced the results of its Re-Form: New Life for Old Spaces, an international ideas competition examining the adaptive reuse of small-scale existing buildings. The competition invited architects and designers to propose transformations of used, abandoned, or overlooked structures with an approximate footprint of 250 square meters, located anywhere in the world. With no fixed site or program, participants were encouraged to explore alternatives to demolition and new construction through reuse strategies grounded in contemporary social and environmental concerns.

As an open-format competition, Re-Form foregrounded sustainability, feasibility, and community impact over formal or typological constraints. Submissions ranged from precise urban insertions to more speculative rural interventions, reflecting a broad range of approaches to working with existing fabric. Many projects focused on how limited, often marginal spaces could be reactivated to support new forms of collective use while responding to material, climatic, and ecological conditions.
