9, 11 Castle Street, Stonehaven

9 and 11 Castle Street in Stonehaven are 18th-century, two-storey houses that form a short terrace, situated on a steeply sloping site to the northeast. The buildings are harled with painted margins and feature snecked rubble on the sides.

The principal elevation faces west and includes a part-glazed boarded timber door located in the bay to the left of the centre. There are windows to the left at ground level and three regularly spaced windows above. A further window is positioned to the right at ground level. Steps lead up to another part-glazed timber door in the bay to the right of the centre, with two additional windows to the right and a single dormer window rising from below the eaves at approximately the centre above. All windows are small, except for the dormer.

The north elevation is a blank gabled wall. The rear elevation, facing east, has been altered and features an out-of-character box dormer window.

The windows are fitted with plate glass glazing in timber sash and case frames. The roofs are covered with grey slates, and there are coped ashlar stacks with some chimney cans, as well as ashlar-coped skews with block skewputts.
