Crosslaw House, Home Street, Lanark

Crosslaw House, located on Home Street in Lanark, was built in 1880. This two-storey building with an attic is constructed from purple sandstone rubble, accented with cream sandstone dressings. The main facade features a central bay and advanced end bays. The central gabled bay includes a Tudor arched doorway with a hoodmould, a two-leaf door with ornamental wrought iron hinges, and single windows on either side. Above, on the first floor, there is a tripartite mullioned and transomed window with a hoodmould, raised in the center over a panel, along with a small attic window. The gable has slightly projecting thin skews and a cast-iron finial.

The end bays, connected to the center by plain three-bay sections, are also gabled, featuring bipartite windows on both the ground and first floors, with a small attic window in the center. The gable treatment mirrors that of the central bay. A base course staircase leading to the door has been replaced by a ramp. The roof is covered with Scotch slates and includes sheet iron ridge ventilators, with ridge chimney stacks flanking the central bay. At the point where the central bay roof meets the main ridge, there is an octagonal cupola supported by Roman Doric columns, featuring a plain frieze and cornice, and a steeply pitched slated roof that rises to a circle of brattishing with finials. Within the column ring is a louvred ventilator.

The sides and rear of the building are unremarkable. There is also a small lodge cottage designed in a similar style to the main block, which features a central doorway flanked by bipartite windows to the left and a single window to the right. All windows, except for the small ones and the upper panes of the tripartite window, are four-pane sash and case.
