Setbacks as Courtyards: How Civil Architecture Reimagines the Gulf House in Bahrain

For centuries, domestic architecture throughout the Gulf has been organized around the courtyard. Houses presented thick exterior walls and limited openings to the street, turning inward toward a shaded garden that structured everyday life. This spatial arrangement responded to both climate and culture. The courtyard brought daylight into deep plans, enabled cross-ventilation, and provided a protected outdoor environment within dense urban fabrics. In the House with Seven Gardens, in Diyar Al Muharraq, Bahrain, the Bahrain-based practice Civil Architecture, one of the winners of the ArchDaily 2025 Next Practices Awards, revisits this spatial tradition through the conditions of contemporary suburban housing. Rather than reproducing the courtyard house as a historical model, the project reinterprets its environmental logic within the regulatory frameworks and spatial conditions that shape much of today's urban development in the Gulf.

Hariri Pontarini Architects and Snøhetta to Design New Ontario Science Centre in Toronto

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.

Drawn by Hand: Géométral's Site-Specific Architecture

Founded in 2022 by Clément Masurier and based in Paris, France, Géométral is an architectural practice defined by design strategies that are linked to the landscape, which it treats as a primary determinant of form. The studio, one of the winners of the ArchDaily 2025 Next Practices Awards, approaches each project as a small universe that combines program, atmosphere, and spatial narratives. Rather than a single signature style, they focus on crafting moods and situations tailored to each context and user.

In its early stages, the studio lacked a built portfolio and responded by developing "fictional architectures" situated on real topographies. This exercise was not merely an aesthetic pursuit but a methodological anchor, as it allowed the firm to establish a rigorous process of site analysis and typological testing before receiving physical commissions. By treating imaginary projects with the same technical scrutiny as real ones, the studio developed a library of formal responses to environmental constraints that now dictate their built work.

Intestines of a Building: Aziza Chaouni on Architecture’s Systems and Resources

In an age so obsessed with skincare and appearances, few architects are truly interested in the intestines of our buildings. With a practice rooted in contextual awareness and technical pragmatism, sensitive to the needs of the people it serves and to resource limitations, Moroccan architect Aziza Chaouni focuses on the hidden systems that allow architecture to be. Over the past two decades, she has been working on projects across different geographies, particularly in the Saharan region, actively engaging with its communities and heritage.

Currently leading the South–North (SoNo) Lab for Sustainable Construction and Conservation at EPFL in Lausanne, Switzerland, Chaouni brings to the academic realm her architectural expertise in operating under pressing constraints, advocating for reciprocal collaboration between the Global South and the Global North. ArchDaily had the opportunity to speak with Aziza about her experience in Africa and how it can foster more sustainable ways of designing buildings for the future of our cities.

How to Design with the Rain: Architectural Strategies for Rainwater Collection across Climates

Subscriber Access | 

As climate variability intensifies, extreme storms are becoming more frequent in some regions while water scarcity deepens in others. Architects are increasingly pressed to reconsider how buildings engage with rainfall as an environmental force and a design resource. How can architecture move beyond shedding the excess water to actively collect, store, and reuse it? What would it mean to treat rainwater as a material that shapes resilient and meaningful spaces?

Tropical Hotels in Costa Rica: Six Projects to Explore Climate-Sensitive Architecture in Central America

Subscriber Access | 

In the coastal and jungle regions of Costa Rica, high humidity and intense solar radiation dictate an architectural strategy centered on permeability rather than enclosure. Unlike the airtight envelopes required in cold climates to retain heat, Costa Rican architecture uses the building envelope as a climatic filter to maximize air exchange. The primary mechanism for managing these thermal gradients seems to be the oversized roof overhang. By extending the roof plane significantly beyond the floor plate, architects create a permanent buffer of deep shade that reduces solar gain and lowers the ambient temperature before air enters the structure. This strategy, combined with permeable or non-existent walls, allows for constant airflow. This is a critical technical requirement for humidity control and the prevention of material degradation through mold and rot.

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.

How Cities Design Public Life in the Shade

Cities are warming at roughly twice the global rate, a trend accelerated by rapid urbanization. While rising temperatures are reshaping daily life worldwide, some towns and neighborhoods, often the most vulnerable and least resourced, are warming more than others. The reason comes down to the urban environment. Built infrastructure, such as roads, buildings, sidewalks, and public spaces, determines how heat moves through a city, where it accumulates, and how long it remains trapped. No matter the climate zone or geographical location, shade remains the most effective and immediate way to cool pedestrians and relieve the built environment.

Designing With Living Systems: Discover the Works of Yong Ju Lee Architecture

What does it mean to practice ecological responsibility beyond performance metrics or carbon calculations? How can fabrication become a design method rather than a final outcome? Founded in Seoul, Yong Ju Lee Architecture is a practice led by architect and researcher Yong Ju Lee. Across installations, research-driven proposals, and cultural projects, the studio positions architecture as an experimental discipline rooted in making: a process in which design emerges from material behavior, prototyping, and fabrication logic as much as from drawing or representation. Bridging professional practice and academia, his work consistently expands the architectural toolkit through computational design, experimental material research, and an evolving commitment to ecology as a responsibility and a design driver. In 2025, the studio was selected as a winner of the ArchDaily Next Practices Awards.

What Informality and Incrementality Reveal About Sustainable Urbanism in India

Subscriber Access | 

The magic of Indian architecture lies in an invisible order amidst visceral chaos. When an uncertain future knocks on the doors of local practitioners, one might begin to look within the four walls they occupy to discover an opportunity for reinterpretation.

Mumbai, Delhi, Bengaluru, and other major metropolises are described as needing massive housing solutions for millions. The instinctive answer is predictable — masterplans, dense towers, and standardized units smeared over haphazard developments. The lexicon misses a deeper truth about how the people already live, work, and build in India. The shorthand used in policy and planning — slum, informal settlement, unauthorized colony — implies a temporary state to be corrected. A designer's eye views these places as layered urban histories, formed through necessity.

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.

Wohnpark Alterlaa: Vienna’s Monumental Vision for Everyday Life

Subscriber Access | 

On the southern edge of Vienna, a cluster of monumental terraces rises above the cityscape, their stepped balconies cascading with greenery and their rooftops crowned with swimming pools. This is the Wohnpark Alterlaa, one of the most ambitious social housing projects in postwar Europe. Designed by Austrian architect Harry Glück and built between 1973 and 1985, the complex was founded on a provocative principle: municipal housing should not only provide affordable shelter but also offer the pleasures and amenities usually reserved for the wealthy.

With more than 3,000 apartments housing nearly 9,000 residents, Alterlaa was conceived as a city within the city. Alongside its residential towers, it incorporates shops, schools, medical services, and cultural facilities, ensuring that daily life can unfold entirely within its boundaries. The project reflects a moment of optimism in Vienna's urban policy, when housing was understood as infrastructure for collective well-being rather than as a commodity.
