Stable Block, Lethangie House

The stable block, dating to circa 1860, forms an L-shaped block alongside a coach house, with a kennel enclosure attached to the north end of the stable block. An enclosing wall with gatepiers stands to the west. The building is in a 17th-century Scots revival style, characterised by crowstepped gables and steeply pitched slated roofs. The construction is of stugged and squared sandstone, with polished ashlar raised long and short quoins and dressings, and chamfered arrises. It features beak skewputts and asymmetrical ridge and wallhead stacks.

The stable block is single storey and attic/single storey and loft. The end (northern) bay contains domestic accommodation on both the ground and first floors. The west-facing courtyard elevation has a domestic bay on the left, containing a single window on the ground floor and a dormer-headed window above, with a crowstepped gablet, sash and case glazing, comprising 2 panes at the bottom and 8 panes at the top. A central entrance is framed by a projecting polished ashlar doorpiece, incorporating beaked skews and a raised heraldic shield bearing the inscription "JP" in the tympanum, and with chamfered arrises to the door.

The stable entrance is positioned off-centre on the north gable, featuring a boarded door and a 3-pane fanlight, with two-leaf boarded doors opening to a hayloft space above. On the east flank, a range of shallow segmental arched windows, fitted with 2-pane hopper glazing, corresponds with five stalls to the left; an off-centre wallhead stack is positioned to the right of the stable block, and the domestic bay on the far right has off-centre sash and case windows on the ground floor. Catslide vent openings are present on the east side. The interior retains original cast-iron stalls and timberwork, including a panelled door with stop-chamfered detail and run-out stops.

The coach house, with coachman's accommodation, connects to the south of the east-west orientated wing. It is two stories high and L-shaped in plan to the north courtyard front. A gable projects to the left, containing a coach house entrance with wide boarded doors on the ground floor and living accommodation above. A recessed bay contains access to the upper floor and a dormer-headed window above. A tall, narrow crowstepped gable faces west. A broad, crowstepped gable, to the south, contains two floors of living accommodation. The gable to the left slopes asymmetrically down to the level of the ground floor lintels, with irregular fenestration. The coach house is linked to the east stable block by a single-storey, two-bay section.
