Ubiquitous up and down the East Coast, Federal-style architecture dates from the late 1700s and coincided with a reawakening of interest in classical Greek and Roman culture.
Builders began to add swags, garlands, elliptical windows, and other decorative details to rectangular Georgian houses. The style that emerged resembles Georgian, but is more delicate and more formal. Many Federal-style homes have an arched Palladian window on the second story above the front door.
The front door usually has sidelights and a semicircular fanlight. Federal-style homes are often called “Adam” after the English brothers who popularized the style.
