The building has large windows which look out over green terraces dotted with trees and shrubs and includes meeting rooms, an atrium, a 300-seat auditorium, a company restaurant with panoramic views and a crèche. The natural light and materials, such as wood and stone, are present throughout. In addition to offices, the building houses a two-storey atrium, a rooftop restaurant area, an auditorium, meeting spaces and an underground car park.
