The building was the creation of Frederick Hervey, 4th Earl of Bristol and Bishop of Derry (known as the Earl-Bishop), who commissioned the Italian architect Antonio Asprucci to design him a classical villa in the Suffolk countryside.
The National Trust refused to sell the remaining lease term back to the 8th Marquess, thereby contravening the Letter of Wishes which states that the head of the family should always be offered whatever accommodation he chooses at Ickworth.
[2] The West Wing at Ickworth House went uncompleted until 2006, when a joint partnership between the National Trust and Sodexo Prestige led to its renovation and opening as a centre for conferences and events.
[citation needed] As one of England's more unusual houses, Ickworth has been unflatteringly described as resembling "a huge bulk, newly arrived from another planet" and as "an overgrown folly".
Unlike the design of a true Palladian building, the terminating pavilions, rather than minor balancing appendages, are in fact large wings, complementary in weight to the rotunda which becomes their corps de logis.
The East Wing, a small mansion in itself, was designed to be the everyday living quarters of the family (which it remained until 1998), thus permitting the more formal rooms of the rotunda to be reserved for entertaining and display.
The west wing, intended as an orangery, sculpture gallery and service rooms remained an unfinished shell until the beginning of the 21st century.
[4] The house has paintings by Velázquez, and Titian, as well as an unrivalled series of 18th-century family portraits by artists such as Gainsborough, Reynolds, Vigee-Lebrun, Batoni, Angelica Kauffman, Ramsay, van Loo, and Hogarth.
