The orangery and linking wing walling to the north-west corner of Montacute House

The orangery and linking wing walling at the north-west corner of Montacute House were built in 1848, possibly by Lewis Vulliamy. The orangery is constructed of ham stone ashlar and features a hipped leaded glass roof made up of small panes. It is a single-storey structure with seven bays, a plinth, and Doric pilasters between the bays and at the corners, all topped with obelisk finials over a quasi-cornice. The orangery has forty-pane sash windows, except for the wider central bay, which contains a pair of glazed doors, each with twenty-one panes. The interior has a timber frame and was undergoing restoration at the time of inspection in September 1985.

The linking wing walling extends approximately 6 metres from the south-east corner of the orangery to Montacute House. This walling is about 2.5 meters high, solid below, and capped with turned balusters and moulded coping. It features a central gateway with square piers topped with obelisk finials and a pair of 19th-century cast iron gates. This structure enhances the setting of Montacute House and is part of the mid-19th century redesign of the grounds.
