 Built in 1897, it is a rare surviving example of a late Victorian orangery in the Classical style, constructed from ashlar and red brick. It has a seven-bay east / west plan with central entrances and three bays north / south, topped by a fully glazed ironwork hipped-roof. An entablature with protruding horizontal geison sits above Ionic half-column supports and corner pilasters. The centre entrance bay on the west front towards the kitchen garden breaks forward as a portico, with pairs of giant engaged columns and broken pediment with a small oculus. Between each pair of columns are large round-headed windows with Gibbs surrounds and keystones.
