After a few months of intense study, the concept has solidified as 'Co-existence' to interweave three elements: Beauty, Seoul, and Collaboration. Based on that, the office has been redesigned whilst enhancing L'Oreal's brand identity foremost, situated at the existing location, Asem Tower in Gangnam District, Seoul.

The hybrid working model was newly implemented which successfully addressed the issue of increasing employees, as well as accommodating the transition of working culture during the COVID era. The technology-focused workspace supported this and achieved the increased wellness area, ample storage for the cosmetics, and the showcase for the visitors.

The iconic design language to support the concept of 'Co-existence' shaped the interchange of Seoul city, one of the major features of a complex metropolitan. And the secondary language became the grid and blocks that were inspired by the window facade of modern skyscrapers. The route was visualised in the space, especially on the ceiling which creates an elaborate pattern, particularly in the Front of House area. That route-inspired ceiling has linked the heritage and culture, for instance, a geometric window pattern of the historic architecture, Han Ok on the L31 reception, and it was also conjoined with the translucent fabric material on the three floor's work cafe ceiling, inspired by the materiality of the traditional garment, Han Bok. The grid pattern is subtly applied mostly on the wall, by the pattern of acoustic panels or the tile arrangements in the cafe area.

On top of this, each floor's major colour represents L'Oreal's business units, the fundamental three sections in the cosmetic industry. The terracotta colour on L31, the reception floor, refers to the colour of Makeup inspired by the blushes and the lipsticks, while L32 and 33 follow the other colours, golden yellow for Fragrance, and aqua blue for Skincare.

Sustainability was prioritised for materials adhering to LEED standards. The reception terrazzo chip was made from the crushed cosmetic bottles collected from L'Oreal, featuring the company's social responsibility. Additionally, work cafes on each floor installed 'super-bins' to promote recycling and sustainable practices among employees.

The office space maintains a consistent design language throughout, with a ceiling band that extends continuously from the entrance. The floor carpet pattern reflects the ceiling design but incorporates an intricate pattern at each corner of the collaboration zones to distinguish them from the rows of workstations. Each department has its own dedicated wall and kiosk-style storage, which can be customised to showcase its products and brand, as L'Oreal encompasses multiple global brands. The uniformity of the design allows for open and adaptable spaces, with all departments positioned next to windows, and a significant amount of mobile furniture to encourage a dynamic work environment.
