Jorge Castillo graduated in 1959 from the Universidad Central de Venezuela Architecture School. His son Juan Carlos took his degree from the same institution in 1991. Juan Carlos is currently on the design faculty of Universidad José María Vargas. He has also taught at Universidad Simón Bolívar. While both father and son have worked on many types of projects, their passion is for small houses. In their residential projects, they explore the idea of "the house inside the house."
