Pent eaves were popular in Colonial Philadelphia
What’s a pent eave?
The “Guide to Historic Society Hill,” published by the Society Hill Civic Association, says pent eaves, pictured above, were common in Philadelphia before the Revolution.
They’re described as: “weather-protective shed roofs overhanging the windows and doorways of the first story, extending the full width of a façade.”
You’ll see them on other homes in Society Hill as well as on Elfreth’s Alley and at the Betsy Ross House in Old City.
