I have admired the details on this house hundreds of times. For years I thought it was the only one in the neighborhood with this motif. Note how the vertical pieces end in a point, and don't touch the windows.
Then I came across this one. One difference, the verticals touch the windows, instead of ending in a point.
On the same block as the one I first admired is this one. The quarter circles and corner pieces are stripped off:
And a few blocks away is a home with just the corner piece. It is a different layout than the others, and doesn't appear to ever have had the vertical piece or quarter circles.
