Thereof, do houses look better with shutters?
It's better to have some windows without shutters than to put them on windows that are too wide for them. Don't use a shutter on one side of a window where a door or the corner of the house prevents you from adding its mate. Also, consider painting shutters the same color as your front door.
Subsequently, question is, why do houses have fake shutters?
Shutters were designed to cover your window for a multitude of reasons. They protect against storms or other inclement weather. The provide relief from the hot summer sun and cold winter winds. They keep rain, hail, sleet and snow off your windows, and extend their life.
Just because they are old, that doesn't mean shutters are out of fashion. The style or design may be the same, but the functionality makes them a worthy choice. Their flexibility and feasibility make them a unique option to install them every year.
