The Walker Guest House
Getting to know the walker guest house (Paul Rudolph, 1952) was one of my favorite assignments way back as an undergrad. Without visiting the site, the assignment was to make plan, elevation, and prospective drawings with interior sections, and build an accurate model, using only information that was publicly available. It was forensic architecture and I loved it! The puzzle of it was fantastic.
I include it here because it was a great exercise in observation and research of a design. The lesson being to see the object, to think about it in three dimensions, and to use the seen as a clue to the unseen thus uncovering facets of the design which would have been otherwise missed.
