The Avian Sanctuary proposes a vertical ecological intervention within the Sculpture Court at Frobisher Crescent, reimagining the Barbican as a living system that supports non-human life alongside its civic and cultural use. Developed within the IITC brief, in which the Barbican is understood as a "vessel mid-journey," the project introduces a tower not as an object but as an environmental and mechanical instrument, a hybrid of architecture and habitat. The Avian provides refuge for urban bird species, insects, and plant life while encouraging human interaction.
