Statement of Special Interest
Part of a B-Group including 'Drygrange House (Grangehall Care Home, Formerly St Andrew's College) Including Garden Terrace Walls to South'; 'Drygrange, Walled Garden'; ' Drygrange, North Lodge Including Gates, Gatepiers and Quadrant Walls'; 'Drygrange, South Lodge Including Gates, Gatepiers and Quadrant Walls'; 'Drygrange, House to North of Steading'; 'Drygrange, Stables and Steading' and 'Drygrange, Summerhouse'.
Significant Scots-Baronial mansion house by Charles Kinnear of renowned Edinburgh architectural practice, Kinnear and Peddie. Commissioned by Edward Sprot of Riddell, Drygrange demonstrates a bold and eclectic mix of Scottish-Renaissance and English Jacobean, with liberal use of corbelling, turrets, crowsteps and castellation and carved details of some distinction. The circular entrance tower, within the re-entrant angle of the L-plan, is of the Castle Fraser and Threave Castle type and dominates the composition. The building is also notable for some outstanding interior detail, particularly in the entrance hall, dining room and former drawing room. The 'Boudoir' plasterwork is probably by Clappertons of Melrose, 1914.
Considerably extended and altered during a change of use to St Andrew's College during the 1960s, including a timber boarded chapel to the SW, and N wing for library and theatre. A conservatory proposed in original plans of 1889, at W elevation, was presumably not executed.
