Pascal Grasso: light and geometry enhance the Centre d'Études Picasso

In the heart of the Hôtel de Rohan in Paris, architect Pascal Grasso reinterprets the Cubist heritage in the design of the new research centre, combining history and modernity through meticulous work on light.

The architect of temporal dialogue

Crossing the threshold of the Centre d’Études Picasso, housed in the former stables of the Hôtel de Rohan, visitors enter a carefully orchestrated interplay of past and present. Pascal Grasso once again demonstrates his ability to transform historic spaces into contemporary venues without compromising their essence. This skill, honed through his work on the Giacometti Institute in 2018, finds expression here in a project where geometry becomes a universal language.

The diamond motif, inspired by the macles adorning the building’s ironwork, serves as both the visual signature of the space and the unifying thread of the design. This shape, which echoes both aristocratic heraldry and the Harlequin costumes painted by Picasso, embodies the meeting point between history and modern art. The architect’s approach follows a tradition of sensitive heritage interpretation: rather than opposing old and new, he creates a dialogue between them through a minimalist reinterpretation of historical forms. His design for the centre’s 720 m² space reflects a holistic vision, with furniture, lighting, and finishes all forming part of the same architectural whole. The slender proportions of the mahogany tables in the reading room echo those of the building itself, creating a fluid transition between eras.

Light as narrative: creating a contemplative atmosphere

Kollectors

In Pascal Grasso’s hands, light becomes an architectural material in its own right. Drawing inspiration from Diego Giacometti’s work for the Picasso Museum, the architect designed custom light fixtures whose geometry evokes Cubist compositions. In the reading room, a choreography of diamond-shaped pendant lights casts overhead illumination, lending the research space an almost museum-like quality. This lighting scheme is complemented by a more intimate approach in the library areas, where linear fixtures integrated into the shelving cast light along the book spines, creating an enveloping atmosphere.

This careful interplay of light reveals the architect’s intent to create ideal conditions for study and reflection. The conference room features an imposing brass light fixture whose sculptural form transforms a functional meeting space into a sensory experience. This approach reflects the influence of minimalist artists on Grasso’s work—for him, light doesn’t simply illuminate the space but reveals its essence. The thoughtful acoustic treatment, featuring a recycled Petac® ceiling, completes this quiet environment that fosters concentration among researchers.

Materiality as vessels of memory

Kollectors

The materials selected by Pascal Grasso situate the Centre d’Études Picasso within a historical continuum while affirming its contemporary character. The solid oak end-grain parquet flooring, whose pattern echoes the exterior paving of the courtyard, establishes a visual link to the building’s history while evoking Cubist fragmentation. The monumental mahogany tables, with their deep reddish tones, bring warmth that contrasts with the austere black finish of the bookcases. This interplay between noble materials and more restrained surfaces reflects the duality between tradition and modernity that defines the entire project.

In the conference room, the brass trim on the monumental table resonates with the historic gilding of the Hôtel de Rohan, creating a material conversation across centuries. This sensitivity to textures and finishes reveals an approach in which architecture becomes as much a tactile experience as a visual one. To realize his vision for the bespoke lighting fixtures—the centerpieces of the project—Pascal Grasso collaborated with the designer and manufacturer Kollectors. Their expertise enabled the development of a design and production process aligned with his architectural intent. This fully custom approach made it possible to refine the design and optimize solutions to achieve both magnificent fixtures and exceptional lighting quality, while enhancing the space and accentuating its modular relief elements.

Through this collaboration and his choice of materials, Pascal Grasso has transformed a research facility into an immersive setting for Picasso’s 200,000-piece archive, where each architectural element serves to honor the artistic heritage while creating an environment conducive to its study.
