4B Lothian Street, Dalkeith

This is a late 19th-century, two-storey commercial building situated on Lothian Street, Dalkeith. The building presents an asymmetrical facade of squared and snecked bull-faced masonry with ashlar dressings and droved rybats. Chamfered reveals have stop-chamfered details above the window sills, and a moulded string course runs between the floors. Pedimented dormerheads are a distinctive feature.

The west elevation (facing Lothian Street) is divided into sections. To the right is a section (4B) featuring a former vehicle entrance with wooden doors and two dormerheaded windows above, the left one with a segmentally-pedimented head. A segmentally-pedimented dormerheaded window sits in the rightmost bay at the first floor, with a blocked ground-floor window alongside it. The section to the left (4A) has a central door and a Venetian window at the first floor with a gabletted dormerhead and ball finial. Two windows are located to the left, including a bipartite window on the far left, and one window to the right. Dormerheaded windows flank the Venetian window on the first floor, the left one segmentally-pedimented.

The north elevation adjoins numbers 4 Lothian Street and 2-6 Newmills Road and is covered by a separate listing.

The east elevation follows an L-plan. It showcases a variety of boarded openings at the first floor, alongside an original hoist on the return. A mid-floor canopied section extends along the elevation, topped with a corrugated-iron roof.

The south elevation is obtusely canted and features four boarded windows at the first floor.

The windows are predominantly sash and case, with a four-pane glazing pattern, a two-pane pattern in the bipartite lights, and a blocked semi-circular head to the Venetian window. The roof is covered in grey slates with a moulded eaves gutter and original rainwater goods that pass through the string course.

An extension, a later U-plan, two-storey brick range, extends from the east elevation of 4B. This range originally served as stables, including a loose box and van sheds, with storage above. The south-facing elevation is of plain brick, while the east elevation is rendered and has various openings, including two first-floor piended dormer windows. To the north (facing Newmills Road), a tall, flat-roofed, single-storey former plant repair shop stands. This section features full-height corniced outer columns, two inner columns flanking a central door, a timber-panelled door with fan lights, and block infill on either side of the door. Upper-level glazing remains. Original signage related to former occupants, "John Monteith Ltd,” is visible within a frieze. A hoist is located at the rear. A section to the right connects to a yard entrance, marked by a pair of chamfered square-plan gatepiers; conical coping stone remains on the east pier, while the west pier has been built upon. A pair of decorative iron gates are also present. A single-storey section adjoins 2-6 Newmills Road.

The courtyard is paved with stone setts, although some are missing or covered.
