At a height of around 60 metres, the new headquarters of L'Oréal Germany forms the northern entrance to the city of Düsseldorf, visible from afar. The design was to embody the values of transparency, innovation and sustainability. The building reflects these values both internally and externally. The building name "Horizon" was derived from the overriding design principle of horizontal structuring.

Upon entering the DGNB Gold certified building, the visitor is greeted by a white-gold interior: The colour scheme provides an elegant but restrained setting for the complexity of the group with its 34 different brands across all floors. The communication zones of the office worlds from the 3rd to the 14th floor, on the other hand, were designed in different styles: Whether an area was designed in the Shabby Chic Look or in the Modern Style was decided by the employees on each floor.

In addition to the open-space areas with a total of 1,000 permanent workplaces, the new working worlds provide for an additional 890 flexible workplaces: These include a number of smaller think tanks, meeting rooms, phone booths and a silent room. This leaves it up to the employees themselves to decide whether they prefer to work sitting, standing or communicatively in a team, or whether they want to use one of the many opportunities for retreat to pursue a task undisturbed.
