Description

62, 64, and 66 Princes Street West in Helensburgh is a three-storey, three-bay tenement building designed by Robert Wemyss in 1896, featuring Jacobean details and a shop at the ground floor. The structure is made of stugged, snecked red sandstone with ashlar dressings. Architectural elements include a cornice at the ground floor, a string course, a bracketed eaves course, chamfered arrises, round-arched windows on the second floor, ashlar mullioned windows, and quoins strips.

On the south elevation facing Princes Street, there is a modern shop at the ground level. The first and second floors have an off-centre window to the right, with a wallhead stack to the left that has a pilaster strip corbelled from the first floor and a dentilled cornice. To the outer right, there is a full-height canted oriel window, with dentilled cills on the second-floor windows and a coped parapet. The outer left features a taller gabled bay with similarly detailed windows, and there is a decorated panel with cusped carving at the apex of the gablehead.

The building has sash and case windows, with plate glass in the lower sashes and multi-pane upper sashes, though some windows have been replaced. The roof is covered with grey-green slate, featuring skewblocks at the gable, corniced sandstone stacks, and original cans.
