Birthwaite Hall Including Attached Range To West

Birthwaite Hall is a large house with an attached range, likely dating from the late 17th century, with significant remodelling in the early to mid 18th century. A further east wing was added around 1825 for Thomas Rishworth, and some early 20th-century internal decorations are also present. The building is constructed of coursed square stone with ashlar dressings and an ashlar east wing, covered by a Welsh slate roof. It has an H-plan and two storeys with attics.

The north front, which serves as the main entrance, is divided into three sections, each with three bays and a gabled form. Raised ashlar quoins, a moulded plinth, and a moulded band mark each floor. A 19th-century infill, designed to blend in, occupies the centre of the main section, with a reset central door. A single-storey addition is attached to the left wing, and the windows are mainly 24-pane sashes, although some have 30 panes. The left wing has blind first-floor windows. Gable apexes feature 2-light double-chamfered windows, and the gable copings are chamfered.

The south-facing garden front is similar, with a 2+3+2 bay arrangement and a central ground-floor infill. This section has two gables, each with a 3-light double-chamfered window. The left return (east wing) is distinguished by a Gothic character, spanning five bays. A central door is present, along with tall ground-floor sashes of 6 over 9 panes and 12-pane first-floor sashes. A Gothic arcaded frieze runs across the facade, with four buttresses rising as octagonal pinnacles, castellated at the top. The parapet and central gable are also castellated. Attached to the right return is a series of single-storey buildings, the south front of which has three sash windows with architraves and cornices, alongside a 20th-century window that is in keeping with the design.

The interior predominantly dates to the early to mid 18th century. The north-facing infill contains an original doorcase with an eared architrave, a swept head, and console brackets. A hall features a bolection-moulded fielded panelled design, while the first floor has flat panelling. A dog-leg stair with a ramped moulded handrail and turned balusters is likely from around 1825. A room on the ground-floor right has dark oak fielded panelling and an intarsia-work panel above a red marble fireplace. A similar scheme is found in the room directly above.
