Ardenhurst Preparatory School

Ardenhurst Preparatory School, formerly Arden House, is a private lunatic asylum dating from around 1820, with an addition of around 1880. It is constructed of stuccoed brick, with rusticated detailing to the ground floor and painted brick returns, topped with a hipped Welsh slate roof featuring internal and return lateral stacks. The building follows a double-depth plan.

The exterior is two storeys with a symmetrical three-bay main range. A plat band runs above the ground floor, and above that is a top frieze and wide eaves soffit. The bays are articulated with large fielded panels that support paired fielded-panelled pilaster strips to the first floor. The entrance is recessed behind two Doric columns, with a doorcase flanked by pilasters, and an overlight with decorative glazing bars to the paired two-panel doors. The ground floor windows are tripartite sashes with a 2/3:8/12:2/3 proportion, while the first floor windows are 8/12 sashes. The left return (garden front) features a central bow with three small-paned windows and a wrought-iron balcony above. An entrance with paired half-glazed doors is positioned on the right side, with 8/12 sashes to the windows.

The rear wing has brick flat arches over 8/12 sashes and 4/8 first-floor sashes. A small re-entrant block sits to the right, alongside a stuccoed end cross-wing with a gable over an 8/12 sash to the ground floor and a large panel above. The rear elevation showcases sashed windows. Attached is a single-storey late 19th-century classroom range with gableted round-headed windows, along with similar windows to the two-storey cross-wings. A glazed single-storey connecting block joins the left return to a late 20th-century wing of matching style. Some cross wing windows are margin-light sashes.

The interior stair hall has a cornice shaped like the soffit of a Greek Doric cornice, featuring a cantilevered staircase with a cut string and bobbin-turned balusters, including central cubes. The landing exhibits architraves to plain doors and a ceiling with fluted coving leading to an octagonal lantern encased by a plaster frame featuring Vitruvian scroll and anthemion corner motifs. Several rooms retain early 19th-century fireplaces, with one front room exhibiting an ornate mid 19th-century oak fireplace. This includes an enriched frieze with a raised central panel and an overmantel with a relief scene depicting a Civil War incident, alongside foliage and linenfold panelling, potentially the work of Willcox of Warwick.

The house was originally constructed as a lunatic asylum for TJP Burman (died 1840) and operated as such until 1876, when it transitioned to a school. Henley in Arden, in connection with Wootton Wawen, was a noted center for private asylums in Warwickshire. The location is linked to the work of Dr John Conolly (1794-1866), a pioneer in the humane treatment of mental illness, who served as visiting physician from 1823.
