I found an online version of a book called Beyond the Bungalow with 10 pages about American Foursquares, with interior and exterior pictures.

When we began the search for our first home, we didn't know what a foursquare was. I liked bungalows, and knew what they were. I always thought of the ones I likes as having a roof that hugged the porch, like the whole house hugged the porch. A porch is a necessity for a house in our minds.

We both love the hundreds of Victorians around, and I have an affinity for the Italianate Victorians in particular. Then again, I'm a sucker for anything with a widow's peak also...

But even though there are tons of Foursquares in Utica, when we picked ours we didn't know what it was yet. Even though we looked at four of them without realizing what they were. My husbands step-mom called ours colonial, and in researching that, which didn't add up, I finally discovered the foursquare.

I think I may get this book for my coffee table in the new house, but then I haven't looked around to see what books are available, I just stumbled across this one. Today I think I'll see what else may be out there.
