Statement of Special Interest
A Group with Northfield House Dovecot (see separate listing). Joseph Marjoribanks altered George Hamilton's original house (late 16th century) in the early 17th century to include the projecting NW wing creating the current L-plan form, and the southern entrance and scale-and-platt stair. The stair turret replaced an earlier turret which was used as the principal entrance. The house was sold to the Syme family in 1703 and they subdivided rooms to incorporate a fashionable interior, including the creation of two rooms and a corridor out of the former Great Hall. These eighteenth century partitions hid and ultimately saved Northfield's 17th century tempera ceiling and wall paintings in the principal rooms. The hanging of a gas chandelier in the 1890s revealed a painted bunch of grapes on the underside of a removed floorboard, but it was not until the 1950s when Schomberg Scott removed much of the Georgian plasterwork, that the spectacularly preserved ceiling paintings, including images of fruit, flowers, birds and animals, were revealed. W Schomberg Scott, architect to the National Trust for Scotland, who lived at Northfield from 1951 to 1997, decided not to restore the former ceilings, but to maintain them in an unrestored state. W F Lyon's sketch of Northfield in 1868 (NMRS) is of interest as it shows the towers as they were originally, with pepperpot caps.
