Elrig Mill House

Elrig Mill House is a two-story, three-bay house dating to 1865, with some modern additions to the rear. The east elevation is of painted squared and snecked rubble, while the remaining elevations are harled. Features include painted rybated margins and long and short quoins to the east elevation, along with ornate cast-iron window guards on the east side.

The principal, east, elevation has a square-plan stone porch at the center, with a doorway to the south featuring a modern door and plate glass fanlight. A set of granite steps lead to the door, accompanied by a decorative cast-iron handrail. Windows are positioned to the east and north, with a string course and a blocking course above. A polished granite panel inscribed "1865" is set into the blocking course on the east side, and two modern urns surmount the porch at the outer corners. The fenestration is regular.

The south elevation includes an enlarged window to the right of center at ground floor, along with a window to the right of center and one to the left at the first floor. A small, segmental-arched window is found in the gablehead. A modern, flat-roofed addition extends from the left at ground floor, continuing around to the west elevation. An outer-right edge features a pair of tall, modern stone gatepiers and a pair of decorative metal gates.

The north elevation has a door to the left of center and windows to the outer right on both floors. A small, segmental-arched window appears in the gablehead.

On the west elevation, a stair window is located to the left of center, and a window sits to the right at the first floor, above a continuous modern flat-roofed addition extending from the south. A lower, two-story gabled wing adjoins to the left, with a single-story gabled wing further adjoined, both featuring various openings.

Four-pane glazing is present in timber sash and case windows on the east elevation; the remaining elevations primarily feature plate glass and four-pane glazing. Red sandstone coped skews are present, along with red sandstone skewputts on the east side, surmounted by modern urns. Harled gablehead stacks rise from the building, with red sandstone copes on the east, west, and north (on the two-story wing). Grey slates, larger and slightly graded, cover the wings. Octagonal cans and red sandstone ridges are also visible.

The garden walls are constructed of rubble with angled rubble coping. A pair of cast-iron gatepiers supporting a spearhead-detailed double-leaf gate are centered on the east side. Remains of mill buildings, now partly incorporating a garden, are visible across the road to the east. Low serpentine, concrete-coped rubble walls have curved decorative cast-iron railings. A pair of square rubble gatepiers, with decorative wrought-iron two-leaf gates, defines a section to the north, while a pair of plain cast-iron gates mark the south section.
