In an era where we now plop down rectangular buildings in the middle of a parking lot, the 1925 Shell Building by Jamieson and Spearl in western downtown teaches us a valuable lesson about the beauty of working with an unusual site plan, not against it.
Due to the platting of Locust Street through Lucas Park, the street doglegs at 13th Street. While the curve of the building is claimed to be inspired in part by the Shell logo of the eponymous oil company based within, certainly the graceful curve works with, not against the odd intersection.
I had a hard time qualifying the architectural style of this building; it is Chicago School in certain aspects, but I get an Art-Deco feeling when I look at it. Besides the shells, it is a remarkably austere and beautiful building.
