The Circular Vault is located at the Technology Museum in Wismar, near the Baltic Sea. Designed as a pavilion, its focus is on sustainability and visitor involvement, highlighting the use of rammed earth as the primary building material. This choice aims to foster a deeper understanding of the material's unique properties and the importance of environmentally friendly construction methods.

Design Concept

The pavilion features a distinctive circular shape, which reduces structural tension while effectively supporting its weight. A large opening faces south, allowing natural light to fill the interior. This design creates a bright and inviting space that encourages exploration and a sense of connection between visitors and the architecture.

Materiality

Constructed entirely of prefabricated rammed earth blocks, each 35cm thick, the pavilion emphasizes sustainability. Rammed earth can be reused without the need for additives, which is essential for promoting responsible construction practices. This approach highlights the project’s commitment to the reuse and recycling of materials within the built environment.

Visitor Interaction

The Circular Vault includes an interactive element, inviting visitors to participate in creating their own rammed earth blocks. This engagement provides hands-on experience with the material, allowing individuals to appreciate the craftsmanship involved. Once shaped, the blocks are set aside to harden in a dry area, demonstrating the time and effort required when working with rammed earth.

To ensure the longevity of the structure, protective measures have been incorporated, including a layer of fleece and a mixture of clay and sealant. This combination helps prevent water from seeping into the building, ensuring its durability against changing weather conditions. The careful attention to detail in material usage and construction methods underscores the pavilion's practical and educational goals.
