For our first office building project, we structured our reflective process around three key pillars, designed to create a cohesive whole suited to the changing world of work and city life. To start, we thought in terms of a renewed form of dialogue between the building and the city around it: transparency would create porousness between its interior and exterior at street level, in order to reflect the new hybridization of working times and uses. Pulling the thread of this approach, we also designed and created a wide variety of working spaces for occupants, ensuring they would be able to use these areas as needed and thereby optimising their workplace quality of life. Finally, we were also able to reduce the project’s carbon footprint to its lowest possible level: the absence of air conditioning led us to go back to the drawing board in terms of the energy performance level of the building’s shell, and the various materials used.
