I am trying to figure out if my house is a true FourSquare. It's been moved, added on to, and the upstairs has been completely reconfigured.

The enclosed stairs are at the back of the (original) house, facing a side entrance. The kitchen has been moved to the addition, so we're not sure where it was originally.

I am not sure it's a kit house, but it seems like it. There are few built-ins, the front room (now an office) has a bay window, and there are several archways.

ALSO, we have 10-foot, coved ceilings all downstairs.

Is this a FourSquare?
