In undergrad at CUArch students used to take a sketching field trip class during the first semester of their second year. (The program has since been reshuffled a few times, it is hard to tell which classes have changed and which have simply had their names changed.) The ambiguously titled “Design Thinking” had Eric Jenkins take students around Washington DC to sketch specific buildings and spaces. I hope I still have that sketchbook, but until I find it I have a few scans, one from the Washington Islamic Center on Massachusetts Ave, and the other from the Scottish Rite Temple on 16th St.

Good to see your sketches. The good news is that we (I) still teach a version of the course but now incorporate design exercises (synthesis) with the field studies (analysis). Thanks for posting!
Glad to hear it. That class was one of the most enjoyable at CUArch.
