The 1725 John Chad House has traditional pent eaves between the stories. I've never seen this feature in person but it looks quite wonderful in this photo.
The brick 1724 Abiah Taylor House, near West Chester, has an unusual second-floor balcony in the center of the pent roof, and restored casement windows. The 1995 frame wing at right was added by architect John Milner, a leader in the continuing farmhouse tradition. These two photos came from this fascinating article.
