Architectural Cases

An ambitious 84-hectare urban development, known as Ion Riva, is taking shape on Istanbul's northern Black Sea coast. This collaborative endeavor brings together global architectural powerhouses Snøhetta, Bjarke Ingels Group (BIG), and MVRDV, along with local design talents KEYM, DB Architects, Rasa, and Bilgin Architects, to craft a distinctive residential area. Currently under construction, the initial phase of this project aims to welcome approximately 3,000 residents, with the first residences anticipated to be ready by 2027.

Central to Ion Riva's identity are four distinct cultural structures that form the neighborhood's communal heart: Snøhetta's 'The Ring,' BIG's 'The Drop,' and MVRDV's 'The Lantern,' complemented by a central hub dedicated to arts, education, and leisure. These architectural focal points transcend mere residential offerings, firmly establishing culture, environmental harmony, and social interaction as the foundational pillars of this comprehensive master plan. Each cultural building is thoughtfully designed to enhance public life. Snøhetta's 'The Ring' is an elegant circular structure spanning a river, conceived as a dynamic space for learning, cultivation, and daily gatherings, deeply connected to the natural rhythms of the river valley. Simultaneously, BIG's 'The Drop' is a striking teardrop-shaped timber edifice on the Black Sea coastline, housing a cafe, restaurant, wellness facilities, and public art spaces, all strategically oriented to capture breathtaking coastal views. MVRDV contributes 'The Lantern,' a versatile cultural center featuring performing arts venues, cinema screens, an art gallery, a bookstore, and community areas, with a roof that ingeniously transforms into a public terrace offering panoramic vistas. A fourth cultural building will further enrich the community, providing studios, exhibition areas, co-working spaces, and sports facilities.

The underlying philosophy of the Ion Riva master plan is a deep respect for and integration with the existing natural environment, harmonizing forest, river, and sea along Istanbul's northern expanse. Residential units and public zones are meticulously laid out to conform to the landscape's topography, ensuring uninterrupted coastal views while minimizing environmental disruption. The initial stage of development encompasses 969 homes, organized into smaller residential enclaves, enveloped by 100,000 square meters of diverse green spaces, alongside a new educational institution and a diverse array of cultural, hospitality, and wellness amenities. Connectivity and well-being are paramount, with a comprehensive network of shaded pedestrian paths and verdant corridors linking homes to essential services. An integrated system of parks, nature trails, and athletic facilities is woven throughout the landscape, encouraging recreation and promoting a healthy lifestyle. The architectural style of the homes draws inspiration from local customs, with each villa featuring a private courtyard. Residents have the flexibility to customize these courtyards from 26 available configurations, while shared amenities within each cluster include communal spaces and swimming pools. The forthcoming arrival of the first residents in June 2027 signifies a pivotal moment, ushering in a novel approach to human-centric neighborhood development along the Istanbul coastline.

This innovative project champions sustainable building practices and advanced renewable energy systems. Structures are constructed using locally sourced stone and cross-laminated timber, with modular timber elements reducing embedded carbon and streamlining the construction process. The entire site incorporates renewable energy, including grid-connected solar panels, and employs rainwater harvesting and greywater recycling to reduce potable water consumption by approximately 50 percent. Furthermore, green infrastructure is thoughtfully integrated to regulate microclimates, enhance air quality, and support biodiversity. The neighborhood also features a sophisticated digital framework, including AI-powered controls, IoT systems, 5G connectivity, and EV charging stations, all designed to foster long-term sustainability and enhance daily convenience for its inhabitants. Ion Riva exemplifies a forward-thinking model for urban living, seamlessly blending advanced design with ecological responsibility and community focus.

In a groundbreaking endeavor, an interdisciplinary team has breathed new life into the centuries-old 'dikengyuan' underground dwellings on China's Loess Plateau. This innovative project not only reimagines traditional architecture for a changing climate but also strengthens community bonds, demonstrating a powerful fusion of heritage and modernity.

A Modern Revival of Henan's Subterranean Legacy

In the picturesque Zhangbian Township, nestled within the vast Loess Plateau of Henan Province, China, a visionary project spearheaded by a team from the University of Hong Kong has redefined the ancient practice of subterranean living. Professors John Lin, Olivier Ottevaere, and Lidia Ratoi, alongside a dedicated cohort of student volunteers and skilled local masons, embarked on a mission to modernize the 'dikengyuan' – traditional underground courtyard houses carved directly into the loess soil. This initiative, known as the 'Underground House of the Future,' seamlessly integrates traditional construction methods with cutting-edge technologies like large-scale 3D printing. The primary goal is to empower these unique architectural systems to withstand evolving climate patterns while simultaneously enriching the social fabric of rural communities. The project highlights the enduring relevance of underground homes, which, despite the rise of modern concrete structures, continue to offer stable indoor temperatures, effectively mitigating both summer heat and winter cold. Following the severe floods of 2021, which devastated many traditional underground dwellings, the focus shifted from mere preservation to adaptive innovation. A key figure in this transformation was Miss Zhu, the owner of the selected dwelling, who actively participates in documenting underground life through social media. Her collaboration with the design team led to the inspired decision to convert her private residence into a vibrant community gathering space. The central courtyard has been ingeniously redesigned as a stepped amphitheater, featuring terraced seating that doubles as pathways and guides rainwater into an advanced drainage system. This stepped surface was crafted using robotic 3D printing with earth-based materials, a technique collaboratively tested during construction workshops. Above the courtyard, a lightweight, translucent tensile canopy, conceived by Ottevaere, filters sunlight while preserving an open-air feel. An aperture in the canopy allows for a newly planted tree, honoring local feng shui traditions and restoring greenery lost to flooding. The surrounding rooms, reinforced with brick vaults by local artisans using traditional bamboo branch guides, now benefit from enhanced natural light and ventilation through new skylights and openings. This collaborative process not only infused new structural techniques but also created local employment, bolstering existing community skills.

This pioneering project serves as a compelling testament to how architectural heritage can be thoughtfully adapted to address contemporary challenges, fostering both environmental resilience and community cohesion. It reminds us that innovation is not always about discarding the old, but often about ingeniously weaving it with the new to create sustainable and vibrant futures. The transformation of a traditional home into a community hub offers a powerful model for rural development worldwide, emphasizing the importance of local wisdom, collaborative effort, and environmental consciousness in shaping our built environments.
