National Bank Of Scotland, 24 West Clyde Street, Helensburgh

The National Bank of Scotland, located at 24 West Clyde Street in Helensburgh, was designed by A N Paterson and Stoddart and completed in 1928. This building features two storeys and an attic, presenting a symmetrical three-bay office layout on a corner site. The exterior is made of cream sandstone ashlar, with a base course, a frieze, and a deep cornice that separates the first floor from the attic, complemented by quoin strips.

On the south elevation facing Clyde Street, there is a slightly advanced gable bay at the center, which includes three windows at the ground level. Above, a tripartite window is located on the first floor, adorned with a wrought-iron balcony. The attic features a tripartite window set in a round-arched panel, protected by a wrought-iron window guard. The building is topped with a corniced apex stack and ashlar coped skews that have urn finials on the skewblocks. The bays on either side are slightly recessed, with a doorway on the left set in a round-arched panel that has cavetto-moulded reveals and a coat-of-arms in the tympanum, topped by a chunky keystone. A window is positioned on the first floor, and a bipartite attic window with a semi-circular pediment breaks the eaves. The outer right side mirrors this arrangement, featuring a window set in a round-arched panel at the ground level.

The west elevation, facing Colquhoun Street, showcases a bay with a shaped gable at the center, flanked by three windows on both the ground and first floors, with a bipartite attic window above set in a round-arched panel. The windows are flanked by additional windows, and a corniced apex stack is present. A deep cornice separates the first and attic floors on the south elevation, which is returned to the outer right, where a moulded panel with a date stone is located below the frieze. A doorway is set in a round-arched recess on the outer left, with a window above on both the first and second floors. Most of the windows are sash and case, featuring plate glass in the lower sashes and small panes in the upper sashes. The roof is covered with grey slate, and the building has ashlar coped skews, skew blocks, and corniced ashlar stacks at the gables, along with original rainwater goods.
