Bruce Lindsey (right), dean of the College of Architecture and Graduate School of Architecture & Urban Design in the Sam Fox School of Design & Visual Arts, leads a group of students in a Renga building workshop Jan. 27-28 in Givens Hall. The workshop was an exercise in collaborative building based on Renga, a Japanese poetry form in which 100 people collectively write a poem with one person writing each stanza in succession. Applied to building, student teams had 30 minutes to build something with two two-by-fours. Each successive team added to what was built. Ten teams of two students built the structure using only one guideline: the structure had to be able to be inhabited.
