Clad in 40cm wide aluminum panels, the building is shaped as an elongated rectangular block that is twisted at its center. These are skilfully arranged like a stack of books, in a fanned composition that generates an illusory twisting effect—as if the structure is rolling over itself. The resulting fluid construction has a distinctive sculptural aesthetic, while seamlessly reconciling the different heights of the river banks. Its particular spatial configuration creates three interconnected exhibition rooms. Two spaces—a narrow, windowless, vertical gallery on the south side and a panoramic, horizontal gallery with floor-to-ceiling glass windows on the north—are connected by a folding shell-like gateway, where floors and walls lined in white wood lamellas merge together with kinetic effect. Both sides of the building serve as main entrances allowing for an uninterrupted, immersive journey. A hidden basement, made of concrete and glass, completes the structure, forming a visual continuation of the river outside.
