A reasoned architecture

The Iléo building places the foundations of a sustainable architecture at the service of mankind and the planet. Its highly
technical façade allows the building’s energy losses to be controlled while simultaneously redefining its image in
the city through an emphatic aesthetic that extends right through to its interior design. The latter places emphasis on the
building’s in-situ concrete structure by creating a naval-like atmosphere linking it to the River Seine, inviting visitors to
embark on a journey through a decor placing emphasis on refined aesthetics and considerable comfort.
