A few weeks ago I went out of town to photograph a very similar school for a National Register of Historic Places nomination. I remember ten years ago people were grousing about 1950's houses now being considered "historic." Well folks, we're into the 60's now and I couldn't be happier about it!
In the 50's and 60's the approach was that new building materials and construction methods should lead to new architectural ideas and designs, (unlike today's "new = cheaper and faster" mantra). Schools were/are a source of civic pride, so it follows that form should meet function along an esthetically pleasing plane.
Yeah, I still like this style of architecture. I'll complain when 70's and 80's buildings becomes "historic!"
