Camellia House, Culzean Castle

Camellia House, Culzean Castle

The Camellia House was designed by James Donaldson around 1815 as a Gothick orangery for the 12th Earl of Cassillis and now functions as a conservatory. It is a single-storey building with a submerged basement, constructed in polished ashlar. The structure comprises a double-height polygonal-plan core with two rectangular-plan wings arranged in a 14-bay configuration of 5-4-5 bays. The building stands alone in the castle gardens with its principal elevation facing south, marked by a stepped plinth at the centre and ends and topped by a crenellated parapet with pinnacles.

The principal south elevation features a double-height projecting centrepiece with paired doors in the centre bays. Ogee-arched apertures light the centre, whilst rectangular apertures serve the wings. The north rear elevation contains two central bays with ogee-arched apertures and blind wings, with steps descending to the basement on the east side. The east and west elevations each have five bays with a door in the centre. All door and window frames are metal with timber sub-frames, the glazing bars forming interlocking pointed arches. A pyramidal timber and slate roof crowns the centre section, with metal-framed glazed roofs covering the wings.

The interior centrepiece rises to double height and includes a clerestorey containing a groined ogival arch supported by columns of clustered colonnettes. The north wall is constructed of ashlar. The floor is flagstone with cast-iron decorative vent covers, and timber rafters are secured with steel cable ties.

When built, the Camellia House represented the height of fashion. The Regency period saw growing enthusiasm for conservatories designed with neo-Gothic styling to maximise interior lighting, following the Prince of Wales's Gothic conservatory at Carlton House built in 1807. These buildings were extremely fragile and vulnerable, making this an exceptionally rare early surviving example. The building originally employed a Roman-type hypocaust heating system for cultivating citrus trees, but the fruit crop failed. Instead, it became a general conservatory and took its current name from the camellia flowers that flourished there. In the late 19th or early 20th century, a steam heating system using cast-iron pipes was installed in the basement. The building subsequently fell into disuse and dereliction until consolidation repairs were undertaken in 1964. It was fully restored and reglazed in 1995, and the heating equipment was removed from the basement.

James Donaldson (circa 1756–1843) originated in Ayrshire and later inherited the estate of Williamshaw in Stewarton Parish. He worked for Robert Mylne and served as a district surveyor for the City of London. He produced a survey plan of Culzean Castle in 1818 and worked on the 1st Marquess's estate at Isleworth, which contained substantial greenhouses.

The Camellia House is part of a group listing encompassing the entire Culzean Castle Estate, including Culzean Castle itself, Castle Walls, Fountain Court, Ruined Arch and Viaduct, Stable Block, Cat Gates, Home Farm, Powder House, Ardlochan Lodge, Dolphin House, Hoolity Ha', Swan Pond Complex, Swan Pond Ice House, Walled Garden, Bathing Complex, Water Works, Shore Boat House, Battery and Mast House, Main Drive Walls and Piers, and Gas Works. Together with its remarkable ornamental landscape, Culzean Castle is acknowledged as the epitome of the Picturesque movement in Scotland and is a work of international importance.

Culzean has been associated with the Kennedy family since the Middle Ages. In 1569, Gilbert, the 4th Earl of Cassillis, granted the property to his brother Thomas Kennedy. In the 1660s, the barmekin surrounding the tower house was breached to create terraced gardens, orchards, and a walled garden for which Culzean became renowned. The caves beneath the castle, now a scheduled monument, were fortified to serve as secure stores. Culzean Castle became the principal family seat when Sir Thomas Kennedy became the 9th Earl of Cassillis in 1759. A continuing programme of improvements was undertaken by Sir Thomas and his successors during the 18th and 19th centuries. The 10th Earl began rebuilding the Castle to designs by Robert Adam, work continued by Archibald (1770–1846), the 12th Earl and later 1st Marquess of Ailsa. From about 1810 onwards, the 1st Marquess commissioned numerous structures, both practical and ornamental, engaging several important architects and landscape designers to embellish the gardens and grounds with ponds, gates, lodges, and pavilions, resulting in several key works of the Picturesque era. The 3rd Marquess undertook modernisation and enlargement of the Castle in the 1870s. In 1945, the 5th Marquess of Ailsa divided the property, transferring the Castle and its immediate policies to the National Trust for Scotland.
