Inverdon House, 3 Racecourse View, Ayr

Inverdon House, located at 3 Racecourse View in Ayr, is a two-storey Italianate villa with a basement, designed by Clarke and Bell in 1845. The building features two four-stage towers and is characterized by band courses that divide the storeys, modillion timber eaves, plain window surrounds, and quoins.

The entrance elevation has seven bays arranged in a 3-1-3 grouping. To the left is a four-stage tower, with an advanced infilled entrance porch and a pierced parapet. There is a single window at the third stage and an arched tripartite window at the fourth stage. A single window is located at the basement near the re-entrant angle to the right, along with a smaller narrow window at the outer right. The adjacent two bays to the left have regular fenestration, including a glazed timber entrance at the basement and an additional single window to the right at the basement. To the right, there is a recessed timber glazed cat-slide entrance porch, a glazed timber door, and a single window in the harled piend-roofed section, with a single blind central window above.

The south elevation, facing Racecourse View, has four bays. A four-stage tower is positioned at the penultimate bay to the right, with single windows at the first two stages of differing sizes, an infilled opening at the third stage, and an arched tripartite window at the fourth stage. There is a slit opening at the basement to the outer right and an infilled balcony beneath a modern ground floor window, along with a pierced parapet. The penultimate bay to the left has a single window at the basement, a canted window at ground floor, and a tripartite window at the first floor. The leftmost bay features a single window at the basement, a single window at ground floor, and a tripartite oriel window at the first floor.
