Trinity Style - Philly's Original Affordable Home

A Trinity house, also known as a band-box house or a Father, Son and Holy Ghost house, is a small townhouse, principally found in Philadelphia, Pennsylvania. Trinity houses are characterized by small size, with three or four floors vertically stacked, each usually consisting of one principal room, many of which were built in the 18th and 19th centuries. They are joined by small, winding stairways, and have few or no interior doors. The Trinity name is derived from three floors, three rooms.
