The Wiltshire Historic Buildings Trust (founded in 1967, sometimes abbreviated WHBT) is a charitable organisation which works to preserve the architectural heritage of Wiltshire, in the West of England.
The Trust was formed in 1967, its purpose being "to preserve property and buildings of architectural and historical interest in the county for the benefit of the nation". It is both a registered charity and a company limited by guarantee.
The money employed by the Trust originated in a single grant made at the time of its foundation by the former Wiltshire County Council, funding which has been described by the Trust's President Lord Lansdowne as "a revolving capital sum".
Since 1967, the Trust has been instrumental in a number of projects for the restoration and conversion of historic buildings large and small. At the end of a project, the restored building is sold, so that the Trust can recover the money laid out and look for a new project.
The restoration projects of the charity have included the following buildings: Barton Farm, Bradford on Avon (sold 1975); Number 23, South Wraxall;Wilton Windmill, near Marborough (completed 1976); Number 3, High Street, Marlborough; Numbers 7, 9, 11, 13, 15, 21, 23 and 25, Church Street, Calne (1987–1992); The Well House, Derry Hill (2002–2003); The Ostler's House, at the Hare and Hounds public house, Pickwick (2003–2004); The Apple Store, Rowdeford (2006); and The Granary, Manor Farm, Yatesbury (2006–2007).
