From a renewed optimism, we explore new solutions to problems often inedited, moving our practice to the margins of the discipline. What once seemed solid, stable and timeless now becomes fluid and multiple, making the temporal dimension the new matter of our century, as important as space, light and matter in the modern classicism.
