Hartfield House, 1 Racecourse View, Ayr

Hartfield House, located at 1 Racecourse View in Ayr, is a classical mansion house built in 1850. It is a two-storey, four-bay structure with a lower two-storey wing at the rear, constructed from painted ashlar stone. The building features a deep base course, a channelled and corniced ground floor, decorative scroll work on the frieze, a dentilled eaves course, and a corniced blocking course. The first-floor windows are segmental-headed with architraves and corbelled sills.

On the south elevation, there is a coupled square-column entrance porch with detailed capitals and an entablature, topped with a low pedimented blocking course and a central finial. The entrance features a timber door with a letterbox fanlight, and there is a single window above it on the first floor. Flanking the entrance are ground and first-floor windows, with tripartite windows on the ground floor and shallow pediments above, supported by brackets. To the outer right, there is a canted window on the ground floor, with central acroterian motifs above it and a Venetian window aligned above on the first floor.

The west elevation, facing Racecourse Road, has three bays. It includes a ramp leading to a label-moulded entrance on the outer left, featuring a two-leaf glazed timber door and a split letterbox fanlight. To the right on the ground floor, there is a single label-moulded window, and the first floor has regular fenestration. A stair from the central bay leads to a converted window on the right at the first floor, which also has a glazed timber door.

The north elevation is harled and features a modern lean-to at the centre of the ground floor, with a leaded round-arched stair window centered above and a flanking window to the left on the first floor. There is a two-storey addition that advances to the outer left.

The east elevation was not visible in 1999. The house has rectilinear pattern sash and case windows, a grey slate piended roof with lead ridges, and corniced wallhead and ridge stacks with octagonal cans. It also features cast-iron rainwater goods.

The interior was not seen in 1999. The property is enclosed by a boundary wall with two pairs of square-plan gatepiers that have segmental-headed caps on the outer left and right.
