Exterior shutters are considered a decorative enhancement of the window area. Shutters visually expand a window and its importance. These inexpensive and popular architectural details add color and dimensionality to a home. Aesthetically pleasing shutters are always of the same style and sized properly for the window opening.
Pictured here is a house with an ugly shutter situation. Look closely at the shutters pictured here. They are of various styles, which is unattractive, and they aren’t properly sized or proportioned to each window. The entire shutter aesthetic is a disaster. It is better to not have shutters, than to gratuitously place mismatched and misized shutters on a house. https://alllosangelespaintingcompany.com/2020/05/not-maintaining-curb-appeal/
