Lulworth House, including attached railings

Lulworth House is a two-storey building with a roughcast and painted front, likely over local rubblestone, and a natural slate roof. It features a double depth plan with a central entrance. The front elevation is roughly symmetrical, displaying five windows on the first floor. The ground floor includes a 19th-century door with two glazed vertical panels, a moulded architrave, and a flat hood supported by heavy brackets. On either side of the door are unevenly spaced tripartite sashes, with 6 over 6 pane sashes flanked by 2 over 2 pane sashes. The first floor windows are all 6 over 6 pane flash framed sashes, with a slightly wider gap between the door and the flanking windows. The roof is high and steeply pitched, hipped on the left and gabled on the right, featuring a ridge stack. There are two flat-topped dormers with early 20th-century steel casements. The property has a railed forecourt with plain wrought iron spike railings and a gate, and there is a cellar to the left front with an entrance door. A rear wing is located on the left side behind the hip, while the rear elevation has not been inspected.

Inside, the house exhibits features from both the early 18th century and early 19th century, along with late 20th-century divisions, particularly on the ground floor. The staircase, dating to the early 19th century, has stick balusters and a continuous handrail, though it has been altered from its original form. The early 19th-century joinery includes panelled doors. The ground floor was not fully inspected during the resurvey. On the first floor, the rear room features a coved early 18th-century plaster ceiling, while another room has a heavy rectangle with an oval within it, crafted in early 18th-century plaster moulding. The attic reveals heavy principal rafters with trenched purlins, with the rafters set into the wall-head in a semi-cruck fashion and hip-cruck construction at the west end.
