A "floating" sanctuary circles a new way of living on Istanbul's Black Sea coast

Snøhetta has designed a residential district and an iconic circular building that spans a river gorge in what will become a completely new neighbourhood with nearly 1,000 homes, 100,000 m² of biodiverse green space, a new school, and a wide range of facilities in Turkey's Beykoz district.

On behalf of the developer Ion, and together with internationally renowned architects MVRDV and Bjarke Ingels Group, Snøhetta has formed a design collective where each practice has been responsible for a portion of the site as well as an iconic building with a social program that will serve as a cornerstone within its respective district.

Snøhetta’s area, Greenhouse, includesThe Ring and approximately 400 residences, along with selected retail spaces and offices.

Parts of the project are already underway, with residents due to move into first completed homes in June 2027.

The Ring is conceived as a built “fight of imagination” - a first act of looking and seeing ourselves in the site, from which to eventually climb into, walk, touch, and simply pass time with nature

A sanctuary for experiencing nature

The Ring takes its name from its dramatic circular form, which is almost floating across the river, providing a sanctuary for experiencing nature. Spanning the valley in a perfect circle, The Ring delivers a model of sustainable living, from the wellness practices of its Longevity Center to its light-touch architecture. Stables and allotments sit beside the river, supporting ecological learning and local food systems.

"The Ring is conceived as a built “fight of imagination” - a first act of looking and seeing ourselves in the site, from which to eventually climb into, walk, touch, and simply pass time with nature," says Tae-Young Yoon, Senior Architect and Project Leader.

The related residences include a range of living sizes and typologies, all emphasizing layered relationships with nature and community. These are separated into five smaller communities of 50 – 80 residences whose identities are formed by their unique landscape qualities and program mix. However, all the residences reflect the region's architectural heritage. All the smaller communities host shared amenities, such as recreation facilities, open to all residents and visitors. Digital systems are integrated across the neighbourhood to support comfort, efficiency, and long-term sustainability.

Landscape as the first architect

The Ion Riva masterplan is shaped by the site's natural ecology, where forest, river and sea meet. Homes and public spaces follow the contours of the land, maximising views to the coastline and valley while keeping intervention to a minimum. The material palette prioritises locally sourced stone and timber, with modular construction enabling efficient delivery and lower embodied carbon across the homes.

Kjetil Thorsen, Founding Partner, Snøhetta, said: “At Ion Riva, we have worked with the landscape as the first architect. The meeting of forest, river and sea creates a natural framework, and our task has been to strengthen those conditions rather than overwrite them. The Ring grows out of this context. It is a place for learning, cultivation, and everyday encounters, shaped by the rhythms of the river valley and the community who will use it. Architecture here is not an object, but a set of relationships between people and nature, evolving over time.”

Nature and resource efficiency

The low-impact approach is continued using on-site renewable energy, including solar panels with grid integration, and green infrastructure that regulates microclimates and improves air quality. Rainwater harvesting and greywater recycling systems are designed to cut potable water demand by 50% and are integrated into low-irrigation landscaping.

Walkability underpins the layout of the neighbourhood, with homes and everyday amenities connected by short routes that follow the landscape. Shaded paths and biodiverse green corridors link the site, creating a continuous experience of movement, nature and community. Recreation, play and wellbeing are supported through a network of parks, green spaces, trails and sports facilities integrated across the masterplan.

Four character-shaping buildings

The Ring will be accompanied by three other, striking houses that together will shape the character of Ion Riva.

Along the coastline, Bjarke Ingels Group has designed the Drop, a timber building in a distinctive teardrop shape that hosts a café, restaurant, wellness spaces and public art. At the heart of the neighbourhood, the Light House provides spaces for culture, learning and recreation, including an exhibition space, library, studios, co‑working areas and sports facilities. The Lantern, designed by MVRDV, anchors the cultural programme with a performing arts centre, cinema rooms, community spaces, an art gallery and a bookshop.

About Snøhetta

For almost 40 years, Snøhetta has designed some of the world’s most notable public and cultural projects. Snøhetta kick-started its career in 1989 with the competition-winning entry for the new library of Alexandria, Egypt. This was later followed by the commission for the Norwegian National Opera and Ballet in Oslo, and the National September 11 Memorial Museum Pavilion at the World Trade Center in New York City, among many others. 

Since its inception, the practice has maintained its original transdisciplinary approach, and often integrates a combination of architecture, landscape architecture, interior architecture, product design and art across its projects. The collaborative nature between Snøhetta's different disciplines is an essential driving force of the practice.

Today, Snøhetta has a global presence, with studios in seven locations spanning from Oslo to Paris, Innsbruck, New York, Hong Kong, Shenzhen, and Melbourne.

Snøhetta is currently working on a wide range of international projects, including the Shanghai Grand Opera House, the Theodore Roosevelt Presidential Library in Dakota, Harbourside redevelopment in Sydney and La Croisette in Cannes, to name a few. 

Recently completed works include Vertikal Nydalen in Oslo, Beijing City Library, the renovation of Musée national de la Marine in Paris, Orionis - the planetarium and observatory of Douai, Airside in Hong Kong, Esbjerg Maritime Center in Denmark, 550 Madison Garden and Revitalization in New York, as well as Volum lamps for Lodes.

Some of Snøhetta's previous projects include Ordrupgaard Art Museum expansion in Denmark, the Cornell University Executive Education Center and Hotel in New York City, Le Monde Group Headquarters in Paris, including the wayfinding and signage, Europe’s first underwater restaurant, Under, the redesign of the public space in Times Square, the expansion to the San Francisco Museum of Modern Art, Lascaux IV: The International Centre for Cave Art, Powerhouse Brattørkaia and design for Norway’s new banknotes.

Snøhetta’s working method simultaneously explores traditional handicraft and cutting-edge digital technology. At the heart of all Snøhetta’s work lies a commitment to social and environmental sustainability, shaping the built environment and design in the service of humanism. Every project is designed with strong, meaningful concepts in mind – concepts that can translate the ethos of its users and their context.

Among many recognitions, Snøhetta has been awarded the European Union Prize for Contemporary Architecture – Mies van der Rohe Award for the Norwegian National Opera and Ballet, and the Aga Kahn Prize for Architecture for the Bibliotheca Alexandrina. In 2016, Snøhetta was named Wall Street Journal Magazine's Architecture Innovator of the Year, and the practice has been named one of the world’s most innovative companies by Fast Company two years in a row. In 2020, Snøhetta was awarded the National Design Award for Architecture, bestowed by Cooper Hewitt, Smithsonian Design Museum. In 2021 and 2022, Snøhetta’s Forite tiles won the Sustainable Design of the Year by Dezeen and Best Domestic Design by Wallpaper* in 2022, and the wayfinding system for Le Monde Group Headquarters was acknowledged with Monocle Design Awards. In 2023, Snøhetta won a number of awards for the Esbjerg Maritime Center and was named Architects of the Year at the Monocle Design Awards, in 2024 included a number of awards to Beijing Library and the BIA 2024 Award to Snøhetta and in 2025, Snøhetta was recognized with the OPAL Special Award for Sustainability, among others.
