Abbey Mission Hall, 19 Lawn Street

Abbey Mission Hall, located at 19 Lawn Street, was designed by T G Abercrombie in 1893. This two-storey building features a roughly three-bay Tudor-style front with gabled dormer heads, mullioned bipartite windows, and an Arts and Crafts style porch. The rear of the building has a rendered brick gabled hall, creating an L-shaped plan. The exterior is constructed from tooled, squared, snecked sandstone with polished sandstone ashlar dressings. Notable elements include a band course inscribed with "ABBEY MISSION HALL," a cill cornice on the first floor, and bracketed eaves between the dormer heads. The ground floor windows have splayed, moulded jambs, while the first floor features splayed unmoulded jambs and shallow relieving arches above the windows. The dormer heads have raised square panels, with the central panel dated 1893, and moulded ashlar skews topped with ball finials.

The front building has seven bays on the ground floor, with doorways located in the second and fifth bays from the left. The principal entrance is in the fifth bay, featuring a two-leaf timber panelled door set within a moulded round-arch architrave. A substantial piend-roofed porch is supported by scrolled brackets at the wall and polished brown granite columns resting on the boundary wall. The second bay from the left also has a two-leaf timber panelled door in a roll-moulded, corniced architrave. The upper floor includes three dormer-headed windows, while the rear elevation of the front building has fairly regular fenestration. The five-bay hall has segmental-arched windows on the south elevation only and two pointed iron ridge vents.

The building features a variety of glazing patterns, including leaded lights and timber sash and case windows with small-pane glazing in the upper sashes, as well as timber-framed windows in the rear hall. The roof is covered with graded grey Scottish slate and red ridge tiles.

Inside, there is a timber stair leading to the upper floor of the front building, which has decorative turned balusters and sturdy newels with dentiled cornices. The first floor hall is fairly plain, with timber-boarded panelling to the dado. The main hall features a trussed ceiling and timber-boarded panelling to the dado, along with timber-panelled interior doors.

The boundary wall, dating from the early 20th century, is made of saddle-coped snecked sandstone and rises at the entrances to form gatepiers.
