Argyle House, 121 High Street

Argyle House, located at 121 High Street, was designed by Alexander Tweedie in 1908. This two-storey and attic shop is built in a free Renaissance style and features three bays on a corner site, highlighted by a curved corner and a lead-domed turret that rises from the first floor. The shop front facing High Street is glazed, and the building is constructed from polished red sandstone with a polished pink granite base course and margins.

Architectural details include a fascia with a small cornice below and a deep cornice above, a corniced cill course, a deep, blocked eaves cornice, and a discontinuous parapet between the dormers that has a corniced cope. The deep eaves cornice is supported by paired brackets at the turret. The first-floor windows are tripartite, featuring roll-moulded stone mullions and architraves, with cornices above that have bracketed pediments over the central lights. The dormers are bipartite and topped with finialed segmental pediments.

On the north (principal) elevation, there is a curved central entrance with a recessed glazed timber door and a scrolled open pediment above. The entrance features a mosaic floor with a Greek Key border, displaying "ARGYLE HOUSE" in curved letters alongside a thistle motif. The ground floor has a timber and plate glass shop front, while the first floor has two tripartite windows and two dormers in the attic. The circular turret at the corner rises from the first floor and is corbelled to an octagonal shape at the second floor, featuring a tripartite window with "ARGYLE HOUSE" painted above it and square windows with projecting cills on the second floor.

The west (Murray Street) elevation includes a two-leaf timber panelled door on the right and a window in the centre. The first floor has both tripartite and single corniced windows, while the attic features a bipartite dormer on the left and a single dormer with a triangular pediment on the right.

The building has plate glass in timber casements, with small-pane glazing in fixed lights above. Corniced stacks rise from the south and east elevations, and the roof is covered with graded grey slate. Decorative cast-iron rainwater goods with hoppers are also present.
