Ardyne, 31 Thornly Park Avenue, Paisley

Ardyne is a large villa built in 1910 by W D McLennan. It stands on Thornly Park Avenue, Paisley, and presents as a 2-storey, 4-bay (grouped 1-2-1) L-plan building with distinctive gabled features. The exterior is predominantly harled, with contrasting red painted dressings highlighting architectural details. Timber transoms and mullions are a key feature.

The principal (south) elevation features two canted bays at ground level, each with a four-light window. The bay to the right sits under an extended gable, while the left bay gives way to a slate-hung first floor with a prominent stack piercing the eaves and an adjacent tripartite window. A full-height canted gable with eight-light windows on each floor is situated to the outer right, with a similar bay to the outer left, but with a shallower first-floor window below a polygonal roof.

The west (entrance) elevation is broadly asymmetrically gabled, featuring small horizontal windows on the ground floor and V-plan windows at the first floor, abutting a jettied gablehead. A sweeping left gable pitch leads down to a low, projecting cantilevered porch, and a set-back panelled timber door.

The rear (north) elevation includes a blank, single-storey bay to the right, connected to the porch. A prominent stack rises from the roof pitch, and a tall eight-light stair window breaks through the eaves into a flat-roofed dormerhead. An advanced gable on the outer left has two closely aligned ground floor windows and a horizontal four-light window above. A timber door is located on the ground floor, with a tripartite window above; this connects to a return with paired timber doors, a long horizontal tripartite window, and a shallower window above, with the outer right light breaking the eaves into a flat-roofed dormerhead.

The east elevation displays varied features including a canted oriel window at the first floor, extending to the right, and a shouldered chimney breast on the outer left.

The windows are primarily 2- and 4-pane glazing patterns over plate glass in timber casement frames, with smaller panes in square windows; leaded coloured glazing is found in the stair window and on the ground floor west side. The roof is covered in red tiles, and the stacks are harled with cans. Overhanging eaves incorporate plain swept bargeboarding.

The interior retains a fine decorative scheme, including a panelled timber vestibule with an inner door and a stair hall with a fireplace, fretwork carving on the timber-balustered dog-leg staircase, and an original pendant light. A drawing room features original plasterwork stencilling, and an apsidal alcove includes a settle flanking a fireplace with a copper canopy and original pendant lights.

Carved timber gates are part of the property.
