Altamount, Coupar Angus Road, Blairgowrie

Altamount is a mansion house, originally built before 1807, with a Scots baronial wing added in 1866 and further extended in the late 20th century. The house is two storeys and an attic, with five bays (grouped as two and three) featuring a double bow-fronted design. It is constructed from snecked rubble stone, with some stugged areas, and has ashlar margins and rusticated quoins. Base, part band, and eaves courses run across the facade, along with corbels. The windows are mullioned.

The south-east (principal) elevation displays three original, symmetrical bays to the right. The central bay features a corniced porch with a block pediment, a panelled timber door, and a plate glass fanlight above, alongside a single window on the first floor. Full-height bowed bays flank the central section, each with a single window on the ground floor and a wide-centre bipartite window on the first floor, leading to a conical roof. To the left of centre, wide-centre tripartite windows are at ground level, surmounted by a band course and a single window above with a raised margin. Moulded corbels flank the windowhead, breaking the eaves into a stepped, finialled stone pediment that contains a shield detail. A small bipartite window is located in the outer left angle, with a single light to a corbelled turret topped with a decorative cast-iron finial. A single-storey, pitched-roof bay with a bipartite window is set back to the outer left, with a low, flat-roofed extension beyond.

The north-east elevation showcases a bowed bay to the right of centre, featuring a large, wide-centre tripartite window on each floor, alongside a single window to the left on each floor, with a small slate-hung dormer window above.

The north-west (rear) elevation presents original piend-roofed bays to the left, featuring a stair window over two small lights at the centre. There’s a window on each floor to the left, and asymmetrical fenestration on the first floor over a lower service wing, and two regularly-disposed timber-pedimented dormer windows flanking a small, modern rooflight. The slightly lower and projecting bays of the Scots baronial west wing extend to the right.

The south-west elevation shows a later wing projecting at ground level, with a variety of elements on its set-back face, including a finialled gabled bay with a bipartite window to the right, a piend-roofed bay to the centre, and a further gable to the left.

The windows use a four-pane and plate glass glazing pattern within timber sash and case frames. The roof is covered with grey slates. Stepped ashlar-coped cornices, brick and ashlar stacks, and cast-iron downpipes with decorative rainwater hoppers are also present. The skewes are ashlar-coped.

The interior retains a fine decorative scheme, including decorative plasterwork, architraved panelled doors, panelled shutters, and brass sash lifts. The stair hall features a timber-balustered dog-leg staircase with ball-finialled newel posts. The first-floor bow windows incorporate anthemion-capitalled, fluted pilasters. There are also fine classical timber fire surrounds.

Gatepiers are square-section and coped ashlar with low, saddleback-coped quadrant boundary walls incorporating decorative ironwork railings.
