The aim of the semester is to develop the implementation plans of the selected designs for the projects planned during the 1st semester, to prefabricate and build/implement them on site.How can we transform the concepts into reality, "bring them down to earth" without compromising the validity of the designs, and if possible, allow the selected technical solutions to reinforce the original ideas. The collaborative work processes and the end-of-semester co-building - similar to the 1st semester of the BA - is a team-building exercise at the same time: bringing together the MA class from external students and from different year groups.
