These distinctive rowhouses were built ca. 1898 as investment property by Lancaster clothing-store owner Jordan R. Foster. Research by Deb Oesch determined that the architect is C. Emlen Urban.
The row has five similar houses. The ornate dormers are in a Flemish Revival style. Bay windows alternate with balconies along the row. Ornamentation includes terra cotta panels and balcony festoons.
This builder / clothier Jordan Foster eventually moved into the house on the left, number 449, with wife Emma (Forbes) Foster in the early 1900s.
