Lodge, Dhuhill, Sinclair Street, Helensburgh

The Lodge at Dhuhill on Sinclair Street in Helensburgh was designed by William Leiper in 1898, with a wing added to the west in 1984. This single-storey building is constructed in the Scottish Baronial style and features an L-plan layout, along with later additions to the west and north.

The exterior is made of stugged red sandstone rubble with ashlar dressings, and the northern addition is harled. It has cill and hoodmould courses, a roll-moulded surround for the windows and door, and an ashlar mullioned bipartite window. The building has rounded angles that are corbelled to square below beak skewputts leading to crowstepped gables.

On the south elevation, which serves as the entrance, there is a porch set in a re-entrant angle with rounded angles corbelled to square below a cornice. It features an ogee-arched pediment with decorative apex detail and two-leaf boarded doors. To the left, there is an advanced lop-sided gabled bay with a window in the center that has a hoodmould course, and a blank panel at the gablehead. At the southwest angle, a circular corner tower is engaged, featuring a bipartite window facing southwest, a cill course, and a conical finialled roof. To the right of the porch, there is a blank wall leading to the wing.

The west elevation includes a modern wing from 1984 to the left of the circular tower, with two windows on the south elevation and a gabled blank elevation to the west.

On the east elevation, facing Sinclair Street, there is a gabled bay with a window in the center that has a semi-circular headed relieving arch. The north elevation features a single-storey wing with two windows on the east elevation.

The windows are sash and case, with plate glass on the lower sashes and multi-pane designs on the upper sashes. The roof is steeply pitched, covered with grey-green slates and red ridge tiles.

The boundary walls and gatepiers consist of cream ashlar piers with stop-chamfered arrises and pyramidal caps. The walls are made of ashlar-coped stugged squared and coursed sandstone, flanking a rubble boundary wall with semi-circular coping.
