Anchorage House, 3 Orchard Avenue, Bothwell

Anchorage House is a house dating to circa 1802, with later alterations and additions. It is a symmetrical, two-storey building of a plain classical design, with a rectangular plan and three bays. It features a square-plan porch and single-storey projections to the rear. The house is constructed of droved ashlar sandstone, with squared and snecked sandstone rubble to the sides and rear. Droved margins define the windows. A base course, eaves course and cornice, and strip quoins are also present.

The south, or principal, elevation features a part-glazed porch with slim Doric columns, a plain architrave, simple frieze, and cornice. A deep-set, part-glazed timber panelled door has a fanlight, with a window above it at the first floor. There is a window at each floor in the flanking bays.

The north, or rear, elevation is irregular, with three bays. A square-plan, piended porch is in the centre bay at ground level, adjoining a pitched projection with a further lean-to brick addition at the end of the right bay. There are three windows unevenly disposed to the left return of the projection; a boarded door to the left return of the brick addition; a modern French window set to the left, and a window set to the right in the right return of the projection. A low, single-storey, lean-to addition is found at ground level in the left bay. A stair window is in the centre bay, and a single window is at the first floor in the right bay. Three dormers are unevenly disposed above.

The east side elevation shows a single bay gabled wall with a two-bay addition to the left of centre. A replacement small-pane glazed door is at ground level, set to the left, with a gablehead stack above.

The west side elevation is a single bay with a window at each floor, set to the right of centre, and a gablehead stack above.

The windows have a variety of glazing patterns with different opening methods, including predominantly four-pane timber sash and case windows to the front. One window on the west elevation may be original, with 16 panes, while the stair window has leaded, small panes. The roof is covered in grey slate, with grey slate also on the projection and additions. Ashlar skews are present, along with ashlar coped stacks (the stack on the west elevation being new) and cast-iron rainwater goods, with some plastic replacement sections to the rear.

The interior, partly viewed in 1997, retains an egg and dart cornice in the drawing room and has timber panelled and architraved doors.

The gate piers are square-plan ashlar sandstone with a string course, cornice, and flattened pyramidal cap. They have replacement wrought-iron gates.
