43-51 High Street, Aberdour

43-51 High Street in Aberdour is an 18th-century building with later alterations. It is a 2-storey house with an attic and a rectangular plan, featuring a 3-storey, 3-bay early 20th-century tenement attached to the rear. The exterior is rendered with stone margins around the openings.

The northwest elevation, which is the principal facade, is asymmetrical. It includes a shopfront with a central recessed door and flanking canted display windows with low stall risers. The far right section of the display window is blocked and incorporates a George VI letterbox along with two defunct vending machines. The shopfront features ventilators, an architrave, a pulvinated frieze, and a moulded cornice. There is also a door on the far left and regularly spaced first-floor windows close to the eaves.

The northeast elevation is attached to 41 High Street, while the southwest elevation is attached to 55 High Street. The southeast elevation has a door off-centre to the left, with flanking windows on the ground floor. The first and second-floor windows are arranged above the ground floor windows, with an extra small central window on the first floor.

The shopfront includes a timber and glass door with a fanlight, along with plate glass windows that have timber astragals. There is a timber boarded door with a fanlight on the far left of the northwest elevation and a modern door on the southeast elevation. The building predominantly features 2-pane timber sash and case windows with horns, and 8-pane sash and case windows on the ground floor of the southeast elevation. A centrally located cast-iron rooflight is flanked by piended 8-pane timber sash and case dormer windows on the northwest side. The roof is pitched and covered with slate, with coped skews and skewputts on the northwest elevation. There is a coped gable apex stack on the northeast and a shared gable apex stack on the southwest, both with polygonal clay cans.

Inside, the building has been modernised for the post office, but the stairwell leading to the tenement retains some original decorative cast-iron balusters.

At the rear, there are three small outbuildings, predominantly made of brick with a central section of stone rubble and a monopitch roof covered with red clay pantiles. The wash house is located at the far northwest and contains remains of a boiler on the northeast wall, two raised sinks on the southwest wall, and a stone tile floor.
