Heine Hediger played a central role in defining the tasks of zoological gardens and reconsidering their operation and construction processes after the Second World War. Hediger established a new scientific field named "zoobiology" in which he propagated principles of animal husbandry, an early state of behavioral enrichment practices. This chapter reveals the relationship between Hediger's topological principles and their spatial and visual implementation. It explains how Hediger's concepts of space were translated and transformed into the three-dimensional building space. Aspects such as the contemporary architectural style and developments of the human-animal relationship influenced the final results. The chapter presents the Africa House, the rhinos and hippos are the main attractions. Reinforced concrete dominates the main faade on the southeast of the Africa House at the Zurich Zoo, although shrubs and trees have grown in the meantime and have covered the concrete relief of the front.
