Columbia Documents of Architecture and Theory, more colloquially known as D, was a biannual journal that compiled selected material from lectures, conferences, and other forms of discourse that took place at Columbia GSAPP. Its focus was generally theoretical, seeking to explore architecture’s engagement with culture and history and to invite leading theorists and practitioners to question the context in which the practice of architecture occurs.

The fifth volume of D includes scholarly essays by Beatriz Colomina and K. Michael Hays; projects by Hani Rashid, Nasrine Seraji, and Toyo Ito; and theoretical essays by Mark Taylor, Chizuko Ueno, and Joseph Abram.
