Fall 2011 Freshman Project. The Merchant's National Bank designed by Louis Sullivan in Grinnell, Iowa was the source of inspiration for this project. Students were asked to complete a 20" x 20" sketch of the bank's "portal", create a 3-D study model, and then a finished 3-D model. Each student then created a large component of the portal (See Pictures). Working time on the drawing was approx. 24 hours.
