Arbour Hill House And Attached Screen Walls, Dovecote And Summer House

Arbour Hill House is a farmhouse, now a house, dating to around 1760. It was built for Robert Conyers Darcy, Earl of Holderness, of Hornby Castle. The building is constructed of sandstone ashlar, with roofs of concrete interlocking tiles and pantiles.

The main house is two storeys high, with three-storey end pavilions, arranged in a 1:1:3:1:1 bay arrangement, the central three bays projecting as a canted bay to both the front and rear. A plinth runs along the base. The ground floor features an arcade of round arches, with recessed blocking except for a doorway in the first bay, a round-arched sash window with thick glazing bars in the fourth bay, a door with a radial fanlight in the sixth bay, and a 20th-century window in the seventh bay. An impost band runs above the ground floor. The first floor has square window openings with flat arches, blind except for a central six-pane sash window. The end pavilions each have a blind oculus on the second floor. An eaves band runs across the front of the house and continues as a second-floor band on the pavilions. The end pavilions have pyramidal roofs, while the canted bays have semi-hexagonal roofs. A concrete interlocking tile roof covers the main section of the house. A central octagonal chimney rises from the roof ridge.

Attached to the main house are single-storey screen walls, each containing a doorway with a plain surround. To the left is a two-storey dovecote with a boarded door in a plain surround with a keyed lintel on the ground floor, a first-floor band, projecting ledges for birds to alight on, and a pyramidal roof. To the right is a two-storey summer house with a first-floor band and a pyramidal roof.

The rear of the house shows a similar ground-floor round arcade with recessed blocking, round-arched sash windows with glazing bars in the first, sixth and seventh bays, and a part-glazed door with a fanlight in the fourth bay. The rest of the ground-floor bays are blind. The first floor has unequally-hung 12-pane sash windows in the first, second, fourth, sixth and seventh bays. Second-floor oculi are present in the end pavilions. The rear of the summer house and dovecote also features a blind oculus set into the first-floor band.

The left return of the dovecote has an oculus set into the band; the right return has a boarded door in a plain surround with a keyed lintel on the ground floor, and a first-floor doorway above. The left return of the summer house has two doorways with plain surrounds and keyed lintels on the ground floor, one part-blocked to the left, and a part-glazed door to the right; the right return has a blind oculus set into the first-floor band.

The interior of the house features round arches in the walls of the ground-floor front room in the canted bay. In the sixth bay, there's an 18th-century open well staircase with stick balusters. The house is of a similar design to Street House in Ainderby Mires, which is constructed of brick.
