Description

Orchil Old Mansion House is an 18th-century building that features a two-storey structure with ochre washed harl and margins. The south front has windows arranged in a pattern of 1-1-1/1/1-1/1. The interior has undergone considerable renovations. The northern wing, which is likely part of the additions made by architect J. Gillespie Graham around 1835, remains intact. This wing is two-storey with a crow-stepped gable and a bay at the north gable. It also features gothic windows on the first floor to the east, which are topped with Elizabethan gablets. Inside, there is a fine drawing room with a rich arched and ribbed ceiling, and a circular conical-roofed northwest tower. The eastern part of the building, which was probably the majority of Gillespie Graham's addition, was demolished before 1901.
