31 Main Street, Auchencairn

31 Main Street in Auchencairn is a late 18th century, two-storey, three-bay house that forms part of a domestic corner block at the intersection of Main Street and Wellwood Terrace. The building is constructed of rubble, painted white, featuring a central door flanked by paired windows on the ground floor. The upper floor has timber sash and case windows with four-pane glazing. The roof is covered with slate and has coped end chimney stacks. An external forestair on the left gable provides access to the upper floor, which is part of No. 29 High Street, noted in a separate listing.

The coursed rubble stone construction is typical for its period, and the architectural features, such as the position and proportions of the upper windows adjacent to the eaves, are characteristic of late 18th century design.

Historically, Auchencairn is a village located near the south shore of Dumfries and Galloway, established in the 17th century as an agricultural village with a fishery and small port at nearby Auchencairn Bay. The village developed around a corn mill, and the oldest houses, including No. 31, are situated near the now-demolished corn mill site to the west. This house is part of a group of earlier buildings in the village, retains its domestic use, and has seen relatively little change to its principal elevation as of 2023.
