On city planning maps, this house is in Chateau, but socially it was at the end of the Lincoln Avenue row of rich people’s houses in Allegheny West. Today it sits surrounded by robotics works and fast-food joints, but it is kept in beautifully original condition by its owners. The architects were Longfellow, Alden & Harlow (or some subset of those three), at the very beginning of their practice—just about the time they designed Sunnyledge, which is something like a stretched version of this house.
