3-5 Duke Street, Fochabers

3-5 Duke Street in Fochabers is a later 18th century, two-storey, three-bay house that faces east. It features a single-storey, three-bay wing that projects from the north gable and a further two-storey wing that projects at the rear, forming an L-shape. This building is mainly covered in whitewashed harl with ashlar margins, which are painted on the street side, while some rear sections retain their original rubble walling without harl. The main entrance is centrally located, with an additional entrance off-centre in the north wing. The two-bay rear wing has large windows on both the ground and first floors in the outer west bay. There are small gable attic windows on both the north and south gables, featuring a 12- and 16-pane glazing pattern. A stair turret with a conical roof is located at the northwest re-entrant angle.

The building has moulded copes on the end stacks, with the stack servicing the single-storey wing at the north being significantly heightened. The roof is made of graded Banffshire slate and has a stone ridge, with run-off skewputts.

Inside, there are some fielded panelled doors and window shutters. The property is enclosed by high rubble garden walls that front both Duke and Castle Streets.
