The Nissen or Quonset hut was invented during WWI, and used in massive quantity during WWII. I love that the huts destined for the Pacific Theater were made entirely of spruce, since steel rusted out too quickly in the tropical environment.
There’s a big Quonset hut behind our sewing contractor’s factory in Springfield, Oregon. It’s currently in use as a machine shop, but I’m constantly threatening to move in. Something pretty attractive about how simple they are. There are also several on the University of Oregon campus that I used to peer into -I’m sure they’ll be torn down soon. All good things….
