27 Westbourne Gardens South, Glasgow

23 Westbourne Gardens South is a terrace of eight houses built around 1879, featuring a distinctive Thomsonesque design. The terrace has 15 bays, with houses numbered 21 to 27 consisting of two bays each, while numbers 26 and 27 are a mirrored pair. Number 20 has a single bay elevation with a canted window facing the main terrace and a stepped-back entrance bay on the east side. The terrace rises three storeys above a basement and is constructed from polished ashlar, which has been stone cleaned and partly painted.

The entrance steps lead up to double-leaf panelled doors, with a vestibule featuring tripartite doors that include glazed sidelights and fanlights. Each house has two-storey canted windows that extend from the basement. At numbers 26 and 27, canted windows are flanked by doorways supported by Ionic columns, with three columns holding a common lintel that connects the canted windows and provides a balcony with a cast-iron parapet on the first floor. Number 21 has a similar doorway.

The remaining windows are single-light sashes with plate glass glazing. A continuous cornice runs above the ground floor, with a band course at the second floor cills. The eaves feature a cornice, and there are corniced axial stacks with octagonal cans on slate roofs. The steps and basement have cast-iron railings, and there is a cast-iron balustrade on the balcony at numbers 26 and 27.

The flank of number 27 is made of painted ashlar and features advanced square projecting windows on the ground floor terminal bays, which are corniced and have a cast-iron balcony (the left balcony is covered by a modern conservatory). The centre bay has an advanced bipartite window with a pediment on the first floor and an architraved open-topped pedimented window on the second floor.

Number 20 is set back from the main terrace and has steps leading over the basement to a projecting Ionic porch. It features a two-light bow window at the angle. The east flank is made of droved ashlar and has three bays with bipartite windows, including a full-height three-light bow window to the left. The rear elevation is also droved ashlar, with slated mansard roofs and tall depressed arch dormers. A coped rubble wall borders the lane.

Square ashlar gatepiers support cast-iron lamp brackets at number 20, and the steps are accompanied by an ashlar balustrade. Leaded glass doors are present at numbers 26 and 27.
