Museum Building, Kelburn Castle, Fairlie

The Museum Building at Kelburn Castle, constructed between 1892 and 1908, is a single-storey, three-bay structure with a rectangular plan made of timber and corrugated iron. It is situated beside the Kel Burn, to the south of Kelburn Castle.

The building features a gabled porch in the central bay, timber barge-board eaves, and a brick base. There are brick stacks at each end topped with clay cans, and decorative cast iron brattishing adorns the roof ridge and porch. The windows are timber-framed with four-pane glazing.

Inside, as observed in 2016, the walls are timber boarded, and the ceiling is an A-frame design with timber panelling. Each gable end has elaborately carved timber fireplace surrounds.

It should be noted that a shelter addition at the rear is excluded from the listing under Section 1 (4A) of the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.
