3 Main Street, Carrington

This is an early 19th century cottage, originally built as a single storey, 6-bay, rectangular structure. It has been altered since its original construction. The exterior walls are built from tooled pink sandstone rubble with contrasting broached dressings. Long and short quoins are visible on the east side of the north elevation. Projecting cills are also a feature.

The north (entrance) elevation is asymmetrical, featuring two 8-pane windows grouped centrally, a boarded timber door located in the penultimate bay to the right, and a window in each remaining bay. The west elevation is also asymmetrical, with a single window positioned off-centre to the right. The south elevation was not visible during a survey in 1998. The east elevation is harled (roughcast) and blank.

The windows are predominantly timber sash and case windows with 12 panes to each sash. The roof is red pantiled with a slate easing course and a stone skew to the west gable. A coped sandstone gablehead stack is present on the west gable, along with two modern, harled ridge stacks topped with circular cans. Cast-iron rainwater goods are fitted.

The cottage forms a group with other buildings in Carrington, including Carrington Village, Nos. 1, 2, and 4 Carrington Mains Cottages, Carrington Mains Steading, and Carrington Mains Farmhouse, which are listed separately. The village was built to serve Carrington Mains, which is part of the Rosebery Estate. Historical records found on Ordnance Survey maps from 1852 and 1892, along with entries in "The Statistical Account of Scotland" (1792) and J Thomas's "Midlothian: An Illustrated Architectural Guide" (1995), document the building's presence. Photographic records are also held by the National Monuments Record of Scotland.
