Strathclyde Regional Council Registry Office, 25, 27 King Street West, Helensburgh

The Strathclyde Regional Council Registry Office, located at 25 and 27 King Street West in Helensburgh, was designed by Robert Wemyss in 1890. This two-storey building features an asymmetrical design, constructed from stugged, snecked red sandstone with ashlar dressings. It has a base course and a partially bracketed cill course at the first floor, along with ashlar mullioned windows that have ovolo moulded arrises and low eaves.

On the northern entrance elevation, there is a semi-circular-arched doorway positioned off-centre to the left, featuring deep-chamfered reveals and modern two-leaf panelled doors, with a wheelchair ramp adjacent. Above the doorway, the inscription 'Rhu Parish Council Chambers' is visible. To the right of the entrance, there is a bipartite window, and a semi-circular-arched pend is located to the outer right. A window can be found at the first floor to the right, with a short pilaster strip to the left that is corbelled at the cill course and has a date stone below it. Another bipartite window is positioned to the outer right. The outer left features a gabled bay with a pair of windows at the ground level and a canted oriel above, topped with a half-piend slate roof. A carved panel is present at the gablehead.

The building has sash and case windows, with plate glass in the lower sashes and multi-pane designs in the upper sashes. The roof is covered with green/grey slate and features a coped sandstone stack on the left gable, along with skew blocks and original rainwater goods.
