4 The Row, Longformacus

4 The Row in Longformacus is a house dated 1820, with later alterations, that stands two stories tall with an attic and features two bays on the front, although it has three bays at ground level as part of an irregular terrace. The exterior is constructed from harl-pointed whin and sandstone rubble, with a rubble base course in some areas.

The southeast elevation, which is the entrance side, has a boarded timber door located in the outer right bay, accompanied by a two-pane letterbox fanlight above it. There is a boarded timber carriage door offset to the right of the center, featuring a timber lintel, and a single window in the outer left bay at ground level. A sandstone plaque is centered on the first floor, inscribed with "1820 W A P/F?" and there are single windows in the outer left and right bays, with gabled timber dormers positioned above.

The northwest elevation, or rear side, was not observed in 1997. The house features 12- and 16-pane glazing in timber sash and case windows, with a 12-pane replacement window on the first floor in the right bay and 8-pane timber casement attic lights. The roof is covered with graded grey slate, and it has raised stone skews with moulded skewputts, along with replacement rainwater goods. There are sandstone apex stacks on the northeast and southwest sides, with various circular cans.

The interior was not seen in 1997. In front of the house, there is a cobbled path that forms part of a continuous stretch along the front of the terrace.
