This exceptional location in the heart of Grand Paris stands out for the very nature of its mixed development concept. It is spread harmoniously across three focal points: music and live performance, contemporary arts and the cybercircus and the cinema. The cultural dynamic and international reach of the project will attract creative businesses to this unique setting. 


The Ile Seguin project is part of a sustainable development initiative. Its ambitious goals will enable it to accommodate all uses of the city (work, leisure, relaxation, shops, services, transport, etc.) and thus attract all types of public (families, students, young working people, OAPs, etc.). The diverse uses of Ile Seguin will allow everyone to enjoy their stay there. Boulonnais will therefore co-habit in harmony with tourists, visitors, employees, artists, etc …

Ile Seguin plans to set an example regarding resource management. Its buildings, some of which will be positive energy, will comply with stringent environmental constraints governing energy, water, acoustics and sunshine hours. Special attention will be paid to wastewater treatment: retention ensured by green roofs, natural infiltration and reuse of rainwater that partly finds its way into the Seine, with controlled quality and flow rate. Jean Nouvel, an internationally-renowned architect, has devised a sustainable urban project that will lend Ile Seguin its full appeal.

Prior to the commencement of works, discussions were held at the end of 2012 on the Ile Seguin urban architectural project. Residents of Boulogne-Billancourt were given the chance to choose from among three projects devised by Jean Nouvel. Project no.2 (255,000 m²) was the one ultimately selected.


Since 2011, a number of major public partners and prestigious private companies have committed to the project’s achievement. The Conseil Général des Hauts-de-Seine voted in favour of the launch of a Public Private Partnership (PPP) for the creation of a music hub at the downstream end of Ile Seguin. This programme will help to set up a musical ensemble of international repute that will form the focus of Culture Valley.

Natural Le Coultre, a major player in fine art logistics and exhibitions, has now signed a contractual undertaking for the creation of R4, and is to launch the contemporary art hub programmed for the upstream end of Ile Seguin. The hub will help to inject new dynamism into contemporary design and the art market in France, while facilitating access for all audiences.
