This 18th-century home, known as the Half House because of its narrow width, sits on the site of what was once the Clampfer family's three-building plot, which included a store that sold West Indian hogsheads. Later on, seamstresses lived there—starting with mantua makers, who mended those spooky cloaks that call to mind a pubescent Christian Slater in The Name of the Rose. Though it's not a mansion you might see on the Main Line, for example, it seems like a palace compared to the other homes on Elfreth's Alley. Aside from a two-story addition that was added in 2007, it has three full walls of windows, getting plenty of natural light; a private yard; a roof deck; radiant and zoned heat and air conditioning; and one of those multi-room entertainment systems that would have made sewing the flag so much less boring for Betsy Ross (who'd now be starring on Real Housewives of Ye Olde City).
