Since TEN Arquitectos was first published in 1998, the firm founded by Enrique Norten has soared to a position of international renown. Conceived to represent the current state of the practice, Working shows twenty unbuilt and in-progress projects with an emphasis on the design process. Sketches give way to study models and then to polished renderings; at each stage in the development of a design, numerous iterations show various directions and investigations. The collection of projects is a timely record of the works by this notable firm.
