_881 Marchmont House "Thomas Gibson built Marchmont House in 1750-54 although it is attributed to William Adam. It has been altered in the past by a number of influential architects such as William Burn (1834) and Sir Robert Lorimer (1913- 20) who removed the external entrance stair. Internally, Marchmont House is magnificent with ornamental plasterwork in the main internal stair and former entrance hall as well as the impressive music room with its carved panelling and fantastic organ. The grand scale of the landscape setting is worth exploring and you are free to picnic in the grounds if the weather is agreeable. Please note Marchmont House is now a Sue Ryder Home and visitors are asked to respect the privacy of the residents at all times."
