This exceptionally designed mixed-use development will house an arts and culture center, hotel, cinema shopping and office space.

Ardian, one of the world’s leading private equity houses, acquired a 70% stake in the 53,000sqm Pointe Amont de l’Île Seguin project, located on the Seine in Boulogne-Billancourt, in close vicinity to Paris. This is one of Ardian’s largest property investments to date.
The project will be co-developed with Emerige, a developer committed to urban transformation, and AOG, a private investment company. The large-scale development will create a fully integrated, mixed-use environment in the heart of the Vallée de la Culture and the ZAC Ile Seguin Rives de Seine developed by SPI Val de Seine Aménagement – a tertiary, leisure, tourist and cultural zone, located close to the headquarters of major companies as well as to several public transports.
Work began in August 2022 and is expected to be completed by late 2025.

A mixed project designed as an ecosystem generating synergies with its environment
The project consists of 3 buildings:

  • A 22,000sqm mixed-use building with a cultural focus designed by Catalan firm RCR Arquitectes (Pritzker Prize 2017) and French agency CALQ Architecture. The building will house shops, a Pathé Cinéma Multiplex with innovative and state-of-the-art auditoriums, and a cultural center as well as offices, steps away from the Seine Musicale and the Albert Kahn Museum.
  • A 4-star hotel designed by the Austrian agency Baumschlager Eberle Architekten. The hotel will target 220 rooms, offering an exceptional setting for business guests and tourists. The space will include bars and restaurants with terraces, a business center, a swimming pool overlooking the Seine and balconies offering direct views over Paris and the Seine.
  • An office building also designed by RCR and CALQ offering 16,000sqm of prime office space. These different but connected and complementary buildings will offer a unique experience for businesses, residents and tourists.

A project fully integrated into its environment
This project was designed to fit seamlessly into Île Seguin’s growing redevelopment and on the Seine’s banks.
These new buildings were designed to complete the island’s cultural scene, such as La Seine Musicale, completed in 2017 and designed by Japanese architect Shigeru Ban (Pritzker Prize 2014) in collaboration with French architect Jean de Gastines.
The quality and service of the buildings will be market-leading with the highest sustainability standards, (HQE sustainable building V3 and BREEAM International New Construction V6).
This urban transformation project is perfectly aligned with Ardian’s strategy of providing sustainable finance to real estate. This is Ardian’s seventh real estate transaction in France since the launch of its first Real Estate fund in 2016.
Since 2010, Emerige and AOG have successfully developed several multi-use urban transformation projects. This includes “Beaupassage” in Paris’ 7th arrondissement, a new district and residential area dedicated to providing a quality lifestyle and good standards of wellbeing.

“With this project, we are signing what will be one of our finest achievements at Ardian Real Estate and one of our largest investments to date. Île Seguin is an exceptional site which is ripe for further redevelopment to the highest standards. This project will bring a new lease of life to the area while respecting its heritage and history. With our expert partners Emerige and AOG, we will make the Pointe Amont de l’Île an attractive mixed-use area that is respectful of the surrounding environment and provide a perfect setting for people who want to live, work and relax.”

“We are delighted that Ardian Real Estate is joining Emerige and our historical partner AOG in this exceptional project. For Emerige, this serves as proof of our ability to carry out complex, large-scale real estate operations. The project on the upstream end of the Ile Seguin is emblematic, whether for its remarkable architectural signature with the architects RCR and Baumschlager Eberle or for its ambitious and innovative mixed-use program with a contemporary art center, a Pathé multiplex, a lifestyle hotel, offices and shops. All of this in a green environment that will harmoniously fit in with the Île Seguin conversion project and its 1.5 hectare park.”

“We are delighted to have joined forces with Ardian Real Estate to develop the Pointe Amont de l’Île Seguin project alongside Emerige. This emblematic project, with a strong cultural orientation, which is designed in compliance with the highest environmental certification standards, is completely in line with our vision of sustainable real estate that echoes our own values as a long-term investor. The privileged partnership that has historically linked us to Emerige and that will link us to Ardian for this project, constitutes a high value-added collaboration.”
