(1840-80)--The architecture of Italy served as the inspiration for this building style, which could be as picturesque as the Gothic or as restrained as the classical. This adaptability made it immensely popular in the 1850s. In New York, the style was used for urban row houses and commercial buildings. The development of cast iron at this time permitted the inexpensive mass production of decorative features that few could have afforded in carved stone. This led to the creation of cast-iron districts in nearly every American city, including New York.

Italianate buildings often have a formal symmetry accentuated by pronounced moldings and decorative details. The commercial buildings resemble Italian palaces and tend to be rectangular buildings of several, spacious stories well suited to their original purposes as work spaces. The facades usually have the following features:

A flat or low-pitched roof

A bracketed cornice and an elaborate entablature

Windows rounded at the top (flattened arches above windows are common, too)

Large moldings over windows, called hood moldings

Columns or pilasters flanking, or separating, windows

Decorative keystones

Quoins

Balustrades

Belt courses or entablatures at each story

Vertical rows of windows and horizontal belt courses giving the building a very regular, compartmentalized look
