 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 .
