Wiston House was built around 1575 with a splendid Great Hall featuring a double hammer beam roof. During the English Civil War, Wiston House was occupied, first by forces loyal to King Charles I, then by parliamentarian soldiers. John Fagge purchased the estate in 1649 and his great-granddaughter, Elizabeth, become heiress to the Estate in 1740. She married Sir Charles Goring, a neighbouring landowner in 1743 and the house has been subsequently owned by the Goring family ever since.

Since 1951, the house has been home to Wilton Park, an executive agency of the Foreign and Commonwealth Office, specialising in high level, international policy dialogues and 2016 marks 65 years of their time here.

This local Grade I listed landmark; popular with both the resident public and more international groups, required elements of both conservation and restoration in order to prevent destabilisation of the 16th Century bay window structure, arising as a result of corrosion in the old iron cramps within the Mullions.

Works to resolve this issue included complete dismantle and reconstruction of the Caen French limestone window with localised stone idents and lime based mortar repairs to adjacent elevations; all new profiled masonry being worked on site by the skilled masons in temporary bank shop facilities. The works required a steel support to be put in place whilst the works were undertaken and new stainless steel tie bars discreetly introduced to minimise any further movement.

Consideration was given to the ongoing commercial activity of the property throughout the works which necessitated scaffold adaptions and aesthetic wrapping to detract visitors from the working areas; as well as noise and hours of work restrictions.
