Antonia and Han presented their new book as part of the ITA Open session to an audience of approximately 500 attendees. In their groundbreaking new book, Han and Antonia challenge the common perception that the development of underground spaces is only for cities that have a scarcity of land. They argue that both the sustainable development goals and the new urban agenda require cities to look at the planning and use of underground space. In a book written for urban planners, urban designers, architects, geologists, engineers, and for policy makers and decision makers, they unveil a hidden urban asset as able to provide solutions for many of the challenges urban areas face now and in the future. The publication of the book is timely as cities are evermore being challenged by rapid urbanisation, climate change and the need for urban resilience.
Han and Antonia combined short anecdotes about writing the book with readings and short explanations from the various chapters, with large-scale images from the book as mouth-gobbing backdrops. The presentation was described as "theatrical performance" that captivated the multinational audience.
