Ref. 29511-1 Sarah Finch-Crisp at Lydiard MansionNEW research has linked work which transformed Lydiard Mansion to Palladian revival architect Roger Morris.

The identity of the architect behind the building's transformation in the 18th century had long been the subject of speculation and debate.

But Hampshire-based architectural historian Carole Fry has uncovered documentary evidence linking it to Morris, who also helped design Goodwood House in West Sussex, Richmond Park in London and Mereworth Castle in Kent.

"This latest discovery is a significant step to understanding the historical and architectural importance of this house," said Sarah Finch-Crisp, keeper of Lydiard Mansion.

Two classical facades and three turrets were built between 1743 and 1746 and the work was linked with Morris in the past because of its appearance.

He was the favoured architect of the 9th Earl of Pembroke, owner of Wilton House near Salisbury, on which the design of Lydiard is closely based.

Now the circumstantial evidence and speculation surrounding Morris, who died in 1749, can be supported by the discovery of an entry in the St John's family ledger at Hoare's Bank.

Working with archivists, Mrs Fry, 31, discovered an account recording a payment on September 10, 1744 to Ro. Morris for £42.

"This discovery establishes that the remodelling commissioned by John, 2nd Viscount St John, is most likely to be the work of Morris," she said.

"By appointing one of the most competent and noted Palladian revival architects of his time, John St John would have been keen to raise his profile locally as the owner of the building as well as demonstrating to the world that he was a man of taste and learning.

"The remodelled house would have represented a new beginning for the St John family under his ownership."

Lydiard Park is currently involved in a major £5.3m project, supported by the Heritage Lottery Fund, to restore the 18th century landscape and gardens and upgrade visitor amenities.

Swindon Council's partners in the scheme are English Heritage, The Countryside Agency and Defra along with business partners, RWE npower, BMW group and Intel UK.
