Strathmartine Castle

Strathmartine Castle is a colonial style house built around 1785. It is a two-storey, rectangular-plan structure that takes on an L-shape due to a single-storey service wing projecting from the northwest corner; a similar wing at the northeast corner was demolished in the early 19th century. The building has five bays and features twin bows. It is constructed of harled rubble and has a grey slate roof. Most of the windows are 12-pane sash and case with painted ashlar margins, and the roof has flat coped skews with skew blocks and end stacks.

On the southeast elevation, there are steps leading to a surprisingly modest central door with a slab canopy. To the left and right of the door are full-height bows, and there is a modillioned wallhead cornice. The gable of the service wing is recessed at the far left and features a tripartite window, with the outer sections being narrower and blind.

The east gable has a bipartite window on the ground floor right and a window in the single-storey lean-to at the far right.

On the west elevation, the gable of the main building on the right is blank, while the service wing advances at the left and has three windows, two of which have unsympathetic modern glazing. The right side has a piended roof, and a drystane garden wall projects from the northwest angle.

The north elevation features a stair window at the centre, with windows on the first floor left and right. The ground floor is masked by a full-width single-storey lean-to that has a window at the centre flanked by projecting rounded bays, each with a window. There is a door at the far right in the lean-to adjoining the projecting single-storey service wing, which has two doors and two windows, one of which is modern.

Inside, the castle retains original doors and shutters, some original chimneypieces with 19th-century inserts, and plain moulded cornices. The geometric stair is complemented by a stair window border glazed with stained glass.

The property also includes two semi-octagonal, droved gatepiers with moulded caps and flat-coped drystane walls adjoining them.
