19 Abercromby Street East, Helensburgh

19 Abercromby Street East in Helensburgh is a two-storey villa built in 1907, designed in an asymmetrical Scottish Arts and Crafts style by Mitchell and Whitelaw. The exterior features harled and painted surfaces, with some areas of stugged and snecked cream sandstone detail and ashlar dressings. A corbel course runs between the ground and first floors, and the eaves are deep and swept overhanging.

On the southeast elevation, there is an off-centre right basket-arched doorway with stop-chamfered arrises and a roll-moulded surround, leading to a half-glazed boarded door. A window is located to the right of the entrance, and a bipartite window is positioned at the first floor. To the left, a taller shaped gable bay is advanced, featuring stugged and snecked sandstone at the ground level with a canted window that is partly recessed between piers supporting a corbelled upper storey. Above, there is a corbelled shallow canted oriel window at the first floor. A recessed bay to the left has a window at ground level and a small window above at the first floor.

The southwest elevation includes a centrally located window at ground level, with a shallow canted oriel window breaking the eaves above and a half-piend roof. There is a similarly detailed bay to the outer left, while a full-height bowed projection to the outer right features cream sandstone at the ground floor and harled surfaces above, with three windows at both the ground and first floors and a conical roof.

On the northwest elevation, a canted four-light oriel window breaks the eaves at the centre. There is a window to the left at ground level and a small window above at the first floor, along with a gable bay to the outer right. A modern carport is located below the oriel window.

The villa features small-pane casement windows and fixed-pane windows with top hoppers. The roof is covered with grey-green slates, and there is a harled coped stack. The eastern elevation has a shaped gable with ashlar coped skews and large scrolled skewputts, along with original rainwater goods.
