The building meets the Boulevard Circulaire with a boutique and a V.I.P. entrance to the lobby above, accessed via a grand interior stair that ascends side-by-side with the exterior stair. The mezzanine accommodates an employee restaurant and a corporate cafeteria with views up and down the Boulevard. At the level of the dalle, the main lobby is augmented by a seventeen-meter-high winter garden, a skylighted oasis at the heart of La Défense in which visitors can meet next to an exotic vertical garden. A second restaurant one level above takes advantage of light and views of the winter garden. The building's thirty office floors offer 1,300 m2 of column-free space configured to maximize light and views. A rooftop clubhouse provides conference facilities including meeting rooms and an 80-seat dining room, all wrapped by an accessible roof garden that frames dramatic views over Paris.
Tour Carpe Diem significantly exceeds French Haute Qualité Environnementale regulations for environmentally responsible development and achieved LEED-CS Platinum certification; it is the first building in France to receive these dual certifications. The building relies on geothermal wells at its main energy source. Additional sustainable design strategies include solar water heating, a heat recovery system, high-performance lighting, controls for daylight dimming, and occupancy sensors.
