A spatially complex reconfiguration of an existing Wits University building. The challenge was to consolidate the fossil collections located in two adjacent buildings into an integrated seamless series of spaces. This was done by joining the basements of two buildings through the insertion of an additional linking piece to create a series of rooms and vaults housing one of the largest and most important fossil collections of ancient dinosaurs, therapsid mammal-like reptiles, plants and fossil hominids in the world. A series of specialist laboratories for fossil preparation and analysis were also provided.
