Grennan

Grennan is an earlier 19th-century farmhouse and adjoining steading, designed in a near quadrangular plan with a longer west jamb. The farmhouse is two stories high and has three bays, constructed from painted rubble with painted raised margins. The windows are primarily 4-pane or plate glass in sash and case style, and there are wallhead stacks on the east and west sides. The roof is piended and covered with purple slates.

On the principal south elevation, there is a fanlit door at the center, with regular fenestration on both the ground and first floors. To the left and right are the gable ends of single-storey steading ranges, with a window in the left gable and a glasshouse attached to the right gable.

The north elevation features a small lean-to porch on the right, which has a door leading to the east return. There is also a window to the right on the first floor. A later gabled painted brick wing is attached at the center, with a window on the ground and first floors to the north, two windows on the ground floor to the east, and a door to the right leading to the west.

In the garden, there is a square slate sundial inscribed "John Cunninghame, 1826," featuring an open iron gnomon and a red sandstone stalk that is not original to the sundial.

The steading is built from painted rubble and has gabled slate roofs. The east range steps up to an L-plan barn to the northeast, which includes a threshing machine and narrow openings at ground level. There is a smiddy in the range to the north, complete with a forge and bellows. Additionally, there is a rubble horse mill walk to the east, equipped with iron gearing, and a variety of glazing, including fixed metal small-pane windows.
