Ardgour, 21 Bath Street, Stonehaven

Ardgour, located at 21 Bath Street in Stonehaven, is a former schoolhouse designed by James Henderson around 1845, with later alterations. This single storey and attic building features three bays and has stone-pedimented dormer heads. The structure has gabled single storey school wings that create an H-plan, along with a taller single storey wing at the rear forming a T-plan. The exterior is harled and painted, accented with chamfered ashlar margins and quoin strips, and includes a base course and chamfered reveals.

On the south elevation, the central bay of the schoolhouse has a gabled porch with a part-glazed panelled timber door, flanked by windows in the outer bays. Above, there are three windows with gabletted dormer heads that break the eaves. The lower gabled wings project from the outer left and right, each featuring a central window and an arrowslit in the gable head.

The north elevation, facing Bath Street, showcases a projecting gabled bay of the schoolroom with a single window at the centre. To the right, there is a gabled porch with a panelled timber door and fanlight on the left, accompanied by two windows to the right. A similar gabled porch on the left has a blocked opening with a tiny pointed-arch air vent inserted, along with two windows. A recessed gabled wing at the right has a central window, while a small modern porch is located in the re-entrant angle on the left. The recessed face to the left mirrors the right but includes a small early lean-to in the re-entrant.

The east elevation is a blank wall of the low wing, featuring a full-height projecting, stepped chimney breast at the centre. The building has late 20th century fenestration, graded grey slates, a coped ashlar gable head, and harled wallhead stacks with cans. The gablet coped skews are topped with moulded pyramidal skewputts.

Inside, the building has been largely modernised in the 1960s and 1970s, but retains two timber and one stone fire surround. The boundary walls are made of random rubble and feature semicircular and flat coping.
