Traquair House is a large fortified country house dating from the fifteenth century and is believed to be the oldest continuously inhabited house in Scotland. Its core is a three-storey tower house constructed around 1492. Over the sixteenth and seventeenth centuries, the building was progressively enlarged and extended, resulting in its distinctive and architecturally complex form.

GRAS has maintained a long-standing relationship with the estate, overseeing multiple phases of alteration and repair across the house and its associated buildings.

The most recent commission involved a detailed investigation and condition assessment of the external harling and stone masonry on the house’s exterior walls and other architectural features. Based on this survey, GRAS prepared a comprehensive set of recommendations for repair. Following the appointment of a specialist contractor, an extensive programme of conservation and repair works was agreed upon and successfully carried out.
