Hour 1: Most of us live, work, commute, eat, and sleep in the built environment, but how many of us routinely discuss that environment and how it affects our lives and culture? We’ll explore the realm of architectural criticism this hour with Brooklyn-based critic, journalist and architectural historian Alexandra Lange and Kate Holliday, assistant professor in the School of Architecture at UTA and director of the newly established David Dillon Center for Texas Architecture. They’ll both participate in the inaugural David Dillon Symposium today and tomorrow at the Dallas Museum of Art and the Nasher Sculpture Center.
