Whitney, Mary, House - Spearfish, South Dakota - U.S. National Register of Historic Places on Waymarking.com

Situated on a comer lot near the original commercial core of Spearfish, the Mary Whitney house is a one-and-one-half story Italianate dwelling with a historic one-story extension on the east side. Rising from a stone foundation, the T-shaped, wood frame building is dad with clapboard siding. It is capped by a pyramidal hip roof with asphalt shingles. The one-story extension is capped by a hipped roof that intersects with the main roof. Other additions have gable roofs and shed roofs. Shed roof dormers project from the west and south facades. Two brick chimneys rise from the roof line. The eaves are supported by paired brackets situated at the corners and at intervals along each facade. An open porch sprawls across the front facade. The porch is capped by a hipped roof supported by six square wood columns. Each column is solid on the bottom half, with a center void in each side of the upper portion. It appears that at one time there was a wood balustrade around the porch. There are several additions to the building. On the south facade is a wood frame addition with clapboard siding and a shed roof. On the north side there are two additional wood frame sections with wide board siding and a concrete block section both covered with shed roofs. On the east side is a one story brick structure covered with stucco and an asphalt-shingled gable roof. This appendage appears to be part of the original building; and is shown as a brick cellar on the 1903 Sanborn map. A bay window projects from the south facade. The bay window on the north has been removed to create an entrance for apartments. Fenestration is generally symmetrical, consisting of one-over-one, double hung units. The front entrance door features paired, tall arched lights and a rectangular transom.
