This paper discusses a project where we, together with a group of 15 graduate students, designed, produced, and built small timber structure (a Camera Obscura) in Trondheim, Norway. The project was part of a full semester course at the Faculty of Architecture of the Norwegian University of Science and Technology (NTNU). The main purpose of the course was to explore the possibilities of prefabrication in timber construction based on file-to-factory processes (digital fabrication). Moreover, we wished to give the students the experience of building a permanent structure in 1:1.
