In a blog post on Steampunk Architecture that I wrote almost three years ago (and which has consistently been one of my more popular posts), I included a picture of the Armour Steiner House in upstate New York which has the distinction of having an octagonal floor plan. Prompted by a post in the always interesting website Atlas Obscura, I looked around for more examples of these unusually shaped buildings. And it turns out there’s an interesting story behind them.
