In the 1940s in the Willamette Valley, there were numerous barns built with a Gothic arch. They were made of laminated 1" dimensional lumber. They were just bent and nailed. This is before glue-lam beams.
Maybe this is why I have an affinity for Gothic arches. Plus which, Shelter by Lloyd Kahn was very important to me in the 70s. Now I find that there is a Shelter Blog.
