Statement of Special Interest
Scale drawings of the masonry survive, signed and dated by Nisbet, March 6th 1770, a month after the contract was signed with William House the mason. The Adam drawings must therefore pre-date this date. The SW (principal) and SE elevations are the main concentration of Adam?s work. The SW elevation has been praised for its sense of movement (a characteristic much advocated by the Adam family), and has been seen as the turning point in the development of the Adam castle style. However, it is unusual in this specific part of the Adam oeuvre, in that the Palladian use of rustication at ground has been continued. The symmetry and the block-format of the house give it a strongly classical air, and it is seen to be the first true synthesis of the classical and the more romantic castle aesthetic. However the hypothetical pre-1770 dating of the Adam involvement in the scheme would make the design of even more seminal importance than often recognised. A Rowan, during research for his PhD thesis, came across a now-lost sketch of the SW elevation for Wedderburn in which the towers were round-plan rather octagonal. Professor Rowan has attributed the drawing to James Nisbet of Kelso, who acted initially as the Clerk of Works and subsequently as architect of further alterations to the building. Such an attribution would bring into question the depth of involvement of the Adam family. The position of the original castle is still to some degree uncertain, as coursed and mortared walls have been discovered under the 2-storey hall, along with rubble from the old tower house. Thus also bringing into question the accuracy of the historical ground plan of the house found in the COUNTRY LIFE article. The wing to the NE which was incorporated into Adam?s and Nisbet?s scheme became structurally unsafe at the beginning of the 19th century and was therefore demolished, so allowing the service court to be created. The panel found above the door to the SE court elevation is carved with a shield charged with a lion rampant, surmounted by a helmet with a stag?s head for a crest, although this is no longer very clear. It was removed from the tower house before demolition and placed upon the present structure. The history behind the original building project from the later 18th century is covered in some detail by A Rowan?s article. The alteration to the entrance hall from a simple single storey arrangement to the present grandiose sweeping stair would appear to date from early 19th century. Rowan has suggested that the porte-cochere and this work may well have been carried out by
J Gillespie Graham, who designed the remodelling of Duns Castle (see separate listing). The house remodelling of Wedderburn was carried out for Patrick Home who also commissioned Paxton. There are some similarities internally between these houses. In 1896 the house was leased out to a family who retained the accounts of any alterations. Very little has been altered since then, despite the house being used as a naval hospital during the 2nd World War. The building was known up until the end of the 19th century as Wedderburn House (relating it back to its origins as a tower house), when it was changed to being referred to as a castle.
