The extension itself is conceived as a solid volume pressed into the ground behind the existing building, deliberately reducing its visible scale and presence in the landscape. A horizontal cut at ground level separates roof and base, visually pulling the mass apart and creating the impression of a heavy volume hovering just above the ground. As visitors move alongside this opening, the tension between weight and void reinforces a sense of dislocation, subtly preparing them for the emotional and historical gravity of the museum experience.

Inside, space, material and movement are carefully orchestrated to support remembrance. The renewed reception area brings together entrance, orientation, shop and café into a calm and legible sequence, while the extension provides flexible rooms for reflection, gathering and special events. Materials are used sparingly and honestly — wood, concrete and aluminium — including reused elements that quietly embed continuity and care. Throughout the project, architecture remains in service of memory, creating the conditions for listening, witnessing and carrying the stories of the camp and its prisoners forward with dignity.
