Agustín Hernández argues for “a living architecture. A functional sculpture.” He discusses the historical development of architecture in terms of the “trinity” made of “architects, users and constructors.” He distinguishes two types of architectural practice: authoritative which is predictable and unoriginal, and creative which he states is both objective and subjective and enables discoveries. Hernández explains his plan for a house using triangular forms. He references psychoanalyst Wilhelm Reich when discussing the plans for a circular house he built for a client. Hernández says all architecture must be modulated and geometric. He shows photographs of his own house, and a house he built largely underground.
