31 Argyle Terrace, Rothesay, Bute

31 Argyle Terrace is a former manse built in the mid to later 19th century. This symmetrical building features two storeys with an attic and has three bays with a gabled design. At the rear, there is a single-storey lean-to addition. The exterior is constructed of random rubble sandstone with whitewashed margins, and it has a whitewashed render plinth. The building showcases moulded eaves and fleur-de-lys finials on the skewed gables. It has narrow strip quoins and stugged rubble quoins, along with stugged long and short surrounds to the chamfered openings, and stepped hoodmoulds at the ground level.

On the entrance elevation, there are stairs leading to a timber panelled door that is centrally located at the ground level, accompanied by a tripartite fanlight and an architraved, hoodmoulded door-surround. A single window is present at the first floor, with a small narrow window centred in the gable. The outer left and right bays each contain single windows on both floors, set within smaller outer gables.

The side elevation consists of three bays, with a single bay addition on the outer left. There are single windows at the ground level in the outer left and right bays, and all bays have single windows at the first floor, although the outer right bay is blind. Two small narrow windows are centred in the gable. The lean-to addition features a single window offset to the right of centre.

The building has replacement aluminium windows at the ground level, while the first floor has two-pane timber sash and case windows, and the attic features timber casements. The roof is covered with graded grey slate and has raised stone skews, with coped ridge stacks flanking the centre, although the cans are missing.

The interior was not seen in 1996. The boundary wall consists of a coped random rubble wall along Argyle Terrace, with whitewashed gatepiers flanking the entrance.
