Stable Block Approximately 5 Metres North East of Castle Hill House Including 2 Pairs of Gatepiers Flanking Its Western End

This is a stable block, later converted to estate offices, approximately 5 metres north-east of Castle Hill House, and it includes two pairs of gatepiers that mark its western end. Built in 1843 by Edward Blore, it has undergone 20th-century alterations. The building is constructed of joint-lined, rendered stone rubble with ashlar dressings, and features a hipped slate roof. The overall plan is T-shaped.

The symmetrical main range has a central cupola, and a wing extends at a right angle to the right end, incorporating a carriageway arch and terminating in a square, domed pavilion. The design is in the Palladian style, matching that of the main house. The main range is two storeys high, arranged as a 4:2:4 bay facade. A modillion cornice runs along the top, above a low parapet with ornamental stone balls. A rusticated blind arcade of three bays is located on either side of a slightly projecting, rusticated two-bay pedimented centrepiece. A square central tower has a balustraded parapet that descends to an octagonal cupola, topped with a pineapple finial. Within the two central bays above the pediment are four-over-six pane sash windows. The flanking bays each have a series of blind semi-circular headed arches rising the full height of the facade; three bays on the left have four-over-eight pane sash windows, while one bay on the right has a similar window. Below those are sixteen-pane sashes with moulded architraves.

The gatepiers flanking the left end of the front facade have moulded caps surmounted by dog sculptures. The range at the right end breaks forward to create the carriageway arch, terminating in a two-storey pavilion with a domed roof and ball finial. A modillion cornice and plat-band decorate it. On its south side are two roundels containing busts, above sixteen-pane sashes with moulded architraves. The east-facing side of this range has similar roundels containing busts over sixteen-pane sashes flanking the carriageway arch, followed by five bays with roundels above sashes in plain reveals.
