Due to the karst relief which dominates in the environment around location, the object is formed as a rotated cube which is partly earthed in the ground towers above it, thus emphasizing its connection to the underground facility. The primary materialization of the object is made of “in situ” formed reinforced concrete structure visible at all five facades of the building, in combination with steel and glass. This type of materialization of the object further achieves visual identity in communication with the karst landscape.
