3 St Leonards Bank, Perth

3 St Leonards Bank in Perth is a Classical villa built around 1830. It is a two-storey, three-bay structure with a symmetrical design. In 1903, W Baillie added a two-storey gabled billiard room extension to the rear, creating a T-shaped plan. The villa is set behind a long sloping garden that faces the South Inch to the east and has its rear towards St Leonard's Bank. The principal elevations are made of ashlar, while the other elevations are primarily constructed from stugged, coursed rubble with ashlar margins. The building features a base course, a band course, and overhanging bracketed timber eaves, along with some raised cills. The billiard room includes round-arched window openings. A low stair turret with a conical roof, covered in banded fishscale slates and topped with an iron finial, is located at the north re-entrant angle.

The principal elevation facing east has a central timber porch adorned with fine metalwork insets. It features a six-panel timber entrance door with a five-light fanlight above. The windows are predominantly plate glass timber sash and case, with some casement windows in the 1903 extension. The roof is piended and covered with grey slates, and there are corniced wallhead stacks with decorative cans.

Inside, as seen in 2009, the original room plan remains largely intact. The hallway includes a part-glazed door with wide part-glazed sidelights and a segmental-arched fanlight above. A timber dog-leg staircase features an unusual scrolled floral-pattern open ironwork balustrade, along with a timber banister and a newel post carved with a gryphon. The interior also has six-panel timber doors, some cast-iron fireplaces, and decorative cornicing. The large former billiard room boasts a fine open timber ceiling with pendants.

The boundary walls to the north, south, and east are made of coped rubble and include a decorative iron gate with later railings. To the west, there are banded, capped ashlar gatepiers and a round-arched Gibbsian door surround with a nine-panel timber entrance door.
