Zeitz MOCAA | Iwan BaanSince the 1920s, Cape Towns iconic grain silo has served as a functional industrial landmark, storing and grading corn across South Africa. After its decommissioning in the 1990s, the Victoria & Alfred Waterfront sought to repurpose the structure. At the same time, the Zeitz Foundation needed a permanent home for its collection of contemporary African art. These objectives converged in a visionary project to transform the silo into the Zeitz Museum of Contemporary Art Africa (MOCAA), turning an industrial relic into a vibrant cultural institution while preserving its historical essence.Zeitz MOCAA Technical InformationArchitects1-7: Heatherwick StudioLocation: Cape Town, South AfricaTopics:SilosArea: 9,500 m2 | 102,260Sq.

The building, though perceived as a single structure, consisted of two distinct sections: the grading tower and forty-two tightly packed vertical concrete silos, each a cylindrical void. The primary architectural hurdle lay in converting these enclosed, utilitarian spaces into open, inviting environments suitable for displaying large-scale contemporary art.The architects, led by Heatherwick Studio, responded with a striking concept: carve out the heart of the building to create a central atrium. This approach, reminiscent of hollowing out a natural stone, gave birth to a soaring cathedral-like space at the museums core. The central atrium, formed by carefully cutting into the silos, became the buildings centerpiece, evoking a sense of awe and reverence typically associated with monumental spaces. The design allowed the original silo structure to remain visible, paying homage to its industrial roots while redefining its purpose for contemporary use.This innovative design not only resolved the challenge of creating large exhibition spaces but also preserved the silos identity, allowing the past and present to coexist within its walls.Spatial Experience: Art and ArchitectureAt the heart of the Zeitz MOCAA is the monumental atrium, a void that serves as the buildings central circulatory hub. The atriums organic form contrasts with the rigid, cylindrical silos, creating a powerful juxtaposition between the raw industrial shell and the fluidity of the carved space. As visitors ascend through the museum, they experience a dynamic interplay of light, volume, and texture, with each gallery floor organized around the atrium, enhancing the spatial experience.The surrounding galleries are designed with flexibility in mind, allowing for the exhibition of a diverse range of contemporary African artworks. From sculptures and large installations to more intimate multimedia pieces, the space is adaptable while maintaining a strong architectural presence. The museums sheer verticality, with its stacked floors and interconnected spaces, offers a unique journey for visitors, encouraging exploration while continuously revealing new perspectives of the central atrium.Natural light, a vital element in the museums design, is carefully modulated. Where the original concrete shell could have created a claustrophobic atmosphere, carefully placed windows, skylights, and transparent sections allow light to penetrate the space, softening the industrial materiality. The play of light across the rough concrete walls introduces warmth, adding a new layer of texture to the visitor experience.Legacy and ImpactSince its completion, the Zeitz MOCAA has emerged as a cultural landmark for Cape Town and the entire continent. It serves as a physical and symbolic space where African art, often marginalized in the global art world, is celebrated and given the platform it deserves. Architecturally, the museum exemplifies how industrial heritage can be sensitively adapted to contemporary needs without erasing its history.The projects success lies in honoring the past while embracing the future. The building retains its rugged industrial charm, with the original concrete silos left intact and visible. Yet, through thoughtful architectural intervention, it has been reimagined as a space that breathes new life into Cape Towns waterfront. The carved atrium, now a defining feature of the museum, serves as a reminder of the structures past function while offering a visionary model of adaptive reuse.Zeitz MOCAA PlansFloor Plan | Heatherwick StudioFloor Plan | Heatherwick StudioFloor Plan | Heatherwick StudioFloor Plan | Heatherwick StudioFloor Plan | Heatherwick StudioElevation | Heatherwick StudioElevation | Heatherwick StudioZeitz MOCAA Image GalleryAbout Heatherwick StudioThomas Heatherwick is a renowned British designer and architect celebrated for his innovative approach to architecture and urban design.
