common gable roof pitched at a 45 degree angle, it was originally covered with wooden shingles, those have been replaced over the years with asphalt. The barn features extensive windows, somewhat unusual outside of dairy barns, with a total of 14 eight-paned, double-hung windows dispersed over three sides of the rectangular structure, north, south and east. On the west side, facing the house, are seven smaller single-pane windows. The double-hung windows are topped with segmented arches constructed from a double row of bricks; the north and south main entrances are also topped with segmented brick arches, each of three rows of bricks. Windmill building Only the foundation remains of the property's windmill. What is left, ten rows of stone above the ground, is completely invisible when the home is viewed by passers-by on Lincoln Highway. The windmill started to fall into disrepair around the 1930s or 40s. The original, specific use of the windmill is unknown.
