The design of the museum evokes a feeling of solemnity and contemplation. Corridors are narrow, winding, and subdued in lighting—mimicking burrows, nests, and tombs—while main galleries expand into larger voids that hold immersive exhibits. The architectural forms are inspired by fossils, skeletal remains, and decaying organisms—expressing extinction not as an abstraction but as something physical and deeply felt.

Materials include rammed earth, basalt stone, weathered steel, and reclaimed timber—chosen for their symbolism, tactility, and longevity. These materials age gracefully, allowing the building to weather and shift over time, like the memory of the extinct it enshrines.
