The three buildings that make up the Palatin complex complete the development of the western part of the Faubourg de l'Arche. With Palatin I, the architects have delivered a small-scale building, reminiscent in shape of other buildings in La Défense. The triangular plot requires a cantilever between the second and sixth floors. This solution, combined with the acute angle treatment, gives the building a Parisian look.

Geographically, the Palatin II and Palatin III buildings mark the completion of the northwestern part of the business district. Three times larger than Palatin I, the construction of these two buildings is based on the same principle. The architects used a honeycomb metal frame with column-free spans to allow for the passage of air conditioning ducts and provide a ceiling height of 2.85 m. The lobby is also designed with a series of inverted V-shaped beams, creating the illusion of a row of arches framing the entrance doors.

Founded in 1969 by Jean-Marie Charpentier, the Arte Charpentier agency has nearly 130 employees. Relatively low-key in the 1970s, it made a name for itself with the design of the Météor Saint-Lazare station in 2003.

In 1997, the agency began a series of collaborations with Robert Lewis Turner, known for his work with Skidmore, Owings and Merrill on the development of London's Canary Wharf. Turner, a specialist in office buildings whose concept is based primarily on flexibility, designs all his projects using metal frames. This has become an increasingly prominent feature in La Défense since the 1980s.
