Storybook Style describes a kind of architecture reminiscent of medieval Europe and reflects upon many Period Revival styles such as French Country, Tudor, Normandy, and Mediterranean. However, Storybook Style is not necessarily a literal recreation, if you will, of any one style, but may be a creative interpretation that captures the quality of being picturesque, quaint and charming in appearance. Often, there is an element of whimsy and creative playfulness on the part of the designer that separates Storybook Style homes from their more formal cousins.
Some such homes appeared on the scene in America during the 1920′s, just before the Great Depression, but examples of them are rare. Perhaps you have seen some. There are a few examples of existing houses that are well-crafted and masterfully built, truly capturing the flavor and spirit of flair of a Storybook Style home. Here are a few links:
