With an air of simplicity and wisdom, engineer Julio Vargas Neumann welcomes us. His two dogs accompany us as we descend after the necessary ascent to enter, and we are also accompanied by the stone walls defining the lot. We sit down and begin – or continue – the interview and conversation regarding the value of ‘shicras‘, local materials, and earth construction. We also discuss criticisms of cement, aluminum, and steel, as well as perspectives on the future of materials in Peru and the world. Likewise, we delve into the long-neglected and recurrent rural problem in South America, discussing the inexorable need to change paradigms and priorities.
