Some remodelings are more exhaustive than others. This structure, for example, was re-imagined somewhere in the past, likely the early 1970’s. The then-popular mansard roof was used as a device to completely conceal the second story while stucco, diamond-paned windows, broken pediments, and decorative blinds were paired with it to create a look which defy any stylistic classification.
Most remodeled houses have some clues as to what the original style was. The changes to this place were so thorough that it is really difficult to tell what it looked like before the changes. It may have been a house, though its position at the back of a corner lot adjacent to an alley suggests that it may have been a carriage house as well. The top of the “mansard” appears to be a low-pitched hipped roof with exposed rafter tails. If original, this could suggest a Craftsman style origin… a Foursquare, perhaps? Then again, the presence of a cupola at the center of the roof suggest the place may once have been Italianate in style; the rafter tails may have once been concealed by a cornice.
Here’s a better view of the cupola:
And a view of the back showing what looks like a former sleeping-porch addition:
Now about those windows…
Here, exterior blinds (commonly called shutters) have been utilized as a type of ultra-wide window frame. The broken pediments have been strrrreeeeeeeeeeeeeeeeeeeetttched apart in order to span not only the window but the adjacent blinds as well! Historically, windows with broken pediments were not frequently fitted with exterior blinds. Diamond-pane muntins further complicate stylistic classification.
