Cottage No: 1, Blackadder Bank

Cottage No. 4 at Blackadder Bank is a later 19th-century single-storey building with an attic, part of a 12-bay group of terraced cottages. The structure features stugged squared and snecked sandstone with polished dressings, while the northern, western, and eastern elevations are finished with harl-pointed sandstone rubble. The southern elevation has shoulder-arched windows at ground level, adorned with a strapwork motif above, and is accented by raised long and short quoins.

On the southern elevation, there are four three-bay cottages that are identical except for being mirrored in No. 3, which is the penultimate cottage on the right. The central entrance features a boarded door with a 2-pane semicircular fanlight above, set within a tabbed and keystoned raised margin. To the left of the center of each cottage (except No. 3) is a bipartite window with an ashlar mullion, framed by a tabbed raised margin with a semi-circular tab above and a round niche in the center. The window in the right bay mirrors the design of the bipartite window.

The northern elevation has undergone later alterations for Nos. 1-3, which are mirrored to No. 3. Each of these cottages has a central door (boarded lower with a 9-pane upper section) and a narrow window to the right, with additional windows in each flanking bay. Cottage No. 4, which is the three-bay group on the outer left, features a window in the left bay.

The southern elevation includes 4-pane timber sash and case windows, while the northern elevation of Nos. 1-3 has modern timber glazing with top hoppers. The roof is covered with purple slates, accented by ornamental bands of fishscale slating. Each cottage has 20th-century platformed dormers in the flanking bays, featuring 18-pane timber casement windows, except for a 9-pane timber casement window in the outer left bay and an ashlar gabled dormer with an ashlar finial in the outer right bay. The twin-flued coped stacks are rendered, except for the brick wallhead to the east.

The interior was not seen in 1996. Additionally, there are pigsties to the north, which is a monopitch sandstone rubble building featuring four boarded stable-type doors.
