Description
Ondara House is a long and relatively low two-storey house positioned at right angles to the sea front. It features a rubble construction with roughcast on the front elevation and a slate roof with gable end stacks. The building consists of a main range with a projecting stair gable at the rear, a short rear wing that may have once been a separate cottage, and an out-building range beyond.
The main house has a three-window range with a central doorway that is sheltered by a good lattice-work porch, featuring dressed stone voussoirs above the door. There are flanking canted bays with ring-moulded shafts and four-pane sash windows. An oriel window is located at the first floor in the gable facing the sea. The rear elevation showcases the projecting stair gable, which has a round-headed window at the upper level and a four-pane sash window below. The rear wing includes two four-pane sash windows on the first floor and a twelve-pane sash window next to a boarded door on the ground floor.
Inside, the main range retains some fine late Georgian details. The central hall features a beautiful staircase at the rear, which is behind a timber screen with two shallow arches. The staircase has a swept rail and square newels. Although the original arrangement of four rooms has been modified to create two larger rooms, the original early 19th-century fielded panelled doorways remain intact both here and on the first floor. The rear wing, or former cottage, retains a chimney stair.
