RAA redesigned the Evolution and Ocean Halls at Rosenstein Museum, Stuttgart, integrating immersive experiences while respecting the historic castle. Trench areas with glazing were added to accommodate exhibits without impacting facades. The Ocean Hall, enhanced as an underwater experience, features a 13-meter Sei whale model and marine-themed graphics. The Evolution Hall focuses on evolutionary science with interactive displays and taxidermy. Both halls showcase unique, large-scale objects within the castle's listed structure in a modern, educational setting.
