The Italianate and Gothic Revival styles are known for introducing romantic irregular asymmetrical silhouettes to American homes, with towers, porches, bay windows, and other elements that broke up the simple rectangular box of earlier houses. But, the Italianate style also appeared in restrained cubical form, as in this villa with a low hipped roof on a symmetrical cubical block topped with a cubical belvedere.
The Italianate style got a toehold before the Civil War and took off after the war, with examples of the style appearing in all parts of the United States.
Italianate is one of 25 styles described and illustrated with multiple examples in Chapter 2 of Restoring Your Historic House, The Comprehensive Guide for Homeowners. The 720-page hardcover book is now at the printer and available for pre-order!
