Inverarnan House

Inverarnan House is a large 18th-century inn facing the road from Crianlarich to the head of Loch Lomond, positioned on the old boundary between Perthshire and Dunbartonshire. It consists of a 3-storey 3-bay core with substantial 19th-century additions dating probably from 1825-30 and 1853, including a significant wing to the right. The stonework is now exposed, having been previously harled and stuccoed (some rendering survives to the rear). The building retains much of its architectural character and forms a prominent landmark in the area.

The west principal elevation comprises a 3-storey 3-bay section (probably the oldest part) with a central gabled dormer breaking the eaves and a central pitched roof entrance porch, which likely served as the original entrance but now has a window in place of a door. To the left is a single storey wing. To the right is a 3-storey single bay projecting gabled section with a pitched roof entrance porch. The far right contains a single bay section with a pair of gabled dormers breaking the eaves. To the rear are two projecting gabled wings, the right-hand one with a gable stack projecting further than the left and raised by a storey in 1853. Small stacks sit on the north and south gables, with a near-central ridge stack.

The roof is of graded slate. The building displays a particularly long and diverse selection of glazing types, including glazed dummy windows. The oldest part features mostly 12-pane timber sash and case windows. The rear and sides have a variety of timber sash and case windows with small leaded panes and chunky central vertical astragals.

The interior has been substantially modernised but retains much historic character. The original floor plan appears to survive in places, with typical low ceilings and shutters to windows in some rooms.

The building has a particularly long history as an inn, noted as such on a map dated 1776. Its likely early function as a droving inn adds further interest to its contribution to Scotland's important agricultural heritage. It is probable that the building housed troops during the construction of the military road from Tarbet to Crianlarich by Caulfield between 1748-53, as many barracks built for road construction subsequently developed into inns.

This building forms part of a group listing with the Drover's Inn Stables and Steading, located opposite.
