Alfriston Clergy House of the nascent, but unknown, National Trust to see if it might be interested in taking on the Clergy House. The SPAB put him in touch with Canon Rawnsley, one of the National Trust's founders. Before the Trust decided to acquire the building another founder of the Trust, Octavia Hill, contacted the Society for advice. In her letter she said that they "will be asked to 'restore' it, so far as that odious word means preserve from decay of course we should wish to do so." This dislike of damaging 19th century restoration practices was confirmed by the National Trust
National Trust for Places of Historic Interest or Natural Beauty under the Charities Act 2006. Its formal purpose is: The trust was founded on 12 January 1895 by Octavia Hill (1838–1912), Sir Robert Hunter (1844–1913) and Hardwicke Rawnsley (1851–1920), prompted in part by the earlier success of Charles Eliot and the Kyrle Society. In the early days, the trust was concerned primarily with protecting open spaces and a variety of threatened buildings; its first property was Alfriston Clergy House, and a decorative cornice there may have given the trust its sprig of oak symbol. The trust's first nature reserve was Wicken Fen, and its first archaeological monument was White Barrow.
