One of the main avenues to wealth in Colonial Philadelphia was being a merchant, especially a ship owner. Trade with the mother country and particularly the Caribbean was controlled and profitable and if you were really lucky, war would break out and you could become a legalized pirate (commonly known as a privateer). There were risks of course - ships were lost at sea and this could be particularly catastrophic if you happened to be on board at the time, which James Abercrombie was just one year after he finished his beautiful house.

At the time it was built, it was one of the tallest in the city and it is a grand expression of Georgian design with a fine frontispiece (unfortunately the current one is not original, but the original would have been as grand). There are also belt courses at each floor, flat arch lintels with contrasting keystones and giant modillions under the cornice. For a Georgian building, the windows are very large which would fill the interiors with daylight. The river was much closer in the Colonial era and Abercrombie probably could have seen his ships from the upper windows.

The house passed to a business associate of Robert Morris, Blair McClenachan who helped found the First City Troop. Unfortunately he joined Morris in bankruptcy. By the 19th century the house had lost its interior and become a warehouse and, by the 20th, a paper bag factory. It was restored in the 1950's.
Abercrombie House
This grand mansion done in the Georgian Style would have been one of the showplaces of Colonial Philadelphia. The ground floor exterior and interiors were lost in the 1800's.
