Lismore, 29 Thornly Park Avenue, Paisley

Lismore, located at 29 Thornly Park Avenue in Paisley, is a two-storey, four-bay gabled villa designed by J Craig Barr and Cook in 1910, with alterations made to the rear in the late 20th century. The villa features a whitewashed harled exterior and has harled transoms and mullions.

The south elevation, which faces the entrance, has its bays arranged towards the center. It features low eaves that are broken by the roof of a semicircular bellcast porch, which has a deep-set two-leaf timber door. To the immediate left of the porch is a bipartite window with a flat-roofed corniced dormer above. On the outer right, there is a narrow gabled bay that pierces the low eaves, containing two closely-aligned bipartite windows at ground level and a square bipartite window in the gablehead. To the left, a broad advanced gable features a flat-roofed semicircular eight-light transomed window at ground level, with four closely-aligned small windows above.

The west elevation is a blank wall with a projecting center chimney breast that breaks the eaves into a gablehead stack.

The north elevation, which is the rear, has a variety of elements due to alterations. It includes a four-light transomed stair window at the center, flanked by asymmetrically-fenestrated gables. To the left, there is a single-storey piended bay, and to the right, a flat-roofed garden room extension at ground level. The windows throughout the villa feature small-pane and plate glass glazing patterns in timber sash and case and casement styles. The roof is covered with grey slates, and the shouldered harled stacks have cans. The eaves are overhanging, and the bargeboarding is plain.

Additionally, there is an arch and gatepiers consisting of an ashlar-coped harled wall with a broad depressed arch and square-section gatepiers.
