Statement of Interest

Tillycorthie Mansion House is a rare structure, in terms of plan form, design and material. Early use of concrete, employed unusually for a country house of some size, combined with Scots Baronial external detail and a mix of interior styles result in a building of some quality and importance. The glazed courtyard is a particularly distinctive feature, with its entrance screen on the SW elevation. Built for James Rollo Duncan, Bolivian tin magnate, Tillycorthie 'is not quite the earliest concrete mansion to be built in Britain ... [and] it is a bewildering amalgam of the high-tech and the sub-baronial' (Shepherd). Sited close to the village of Udny, the Tillycorthie estate was purchased in 1899 by J R Duncan, a native of New Leeds, and partner in the firm Penny & Duncan Bolivia. The 1911 development also included the nearby artificial lake (formed from railway sleepers), a brick chimney rising in an adjacent field and served by a long underground flue, power-house and workshop with 24' wheel and skating rink on the roof, as well as two baronial lodges. Mr Duncan also built much of the village of Udny Station. John Cameron (attributed designer of Tillycorthie) is listed as 'builder' but not architect in Walker's Dictionary, he was also involved in building some houses at Udny. Some years ago there was a plan at the house entitled 'Plan of Ground, Spanish Villa, Tillycorthie, Udny'. This reference to Spanish architecture presumably derives from the original owner's business connections, and the lack of named architect leads to the conclusion that J R Duncan was probably responsible for much of the design. The current (2007) owner has learned from Duncan family descendants that they have an engraved crystal bowl which was presented to J R Duncan by the main contractors upon completion of the building. The covered courtyard, a huge span for a glass roof (now (2007) restored using sophisticated modern engineering techniques), was designed to accommodate the turning circle of Duncan's car, and housed a large granite fountain from New Market in Aberdeen. Hennebique's British agent L.G. Mouchel published plans and a list of works in 1920, providing evidence that the hollow-walled construction is entirely in Mouchel-Hennebique ferro-concrete (See Cusack, pp481-82, 543, 545). By 1969 Tillycorthie was in use as an agricultural store and during the 1980s it was unsympathetically converted into three separate dwellings. The George Bennet Mitchell chimneypiece from the Christmas Room and statues from niches in the Billiard Room chimneypiece were removed at this time. The current (2007) owner purchased the three separate dwellings and has returned Tillycorthie to a single property. Statement of special interest and references updated in 2017.
