Grange Manse, West Loan, Prestonpans

Grange Manse is a two-storey, three-bay house built around 1845 in a plain classical style. The front and rear are constructed from squared and snecked sandstone rubble, while the sides feature more random stonework. The building has stugged dressings with raised and droved margins.

The west elevation has three symmetrical bays, featuring a central porch with a pediment and a round-arched doorway. This doorway is backed by a panelled door with a plain arched fanlight, flanked by two windows. The first floor has three windows.

The east elevation is plain and irregular, including a central stair and a single-storey lean-to on the left. The south elevation is asymmetrical, with two windows on the ground floor and one on the first floor. The north elevation is mostly blank, except for a single window on the ground floor.

All windows are 12-pane sash and case without horns. The roof is piended and covered in graded Scotch slate, with a later tiled ridge. There are saddled stacks at each end made of squared sandstone, featuring cavetto copes and three decorative octagonal cans. A single stack at the rear is in the same style, but the cans are missing.

The interior was not seen in 1996.

At the rear of the house, there is a single-storey outbuilding made of snecked rubble with droved ashlar dressings. This outbuilding has two windows and a door on the west elevation, and three windows on the east elevation. The windows are six-pane, top-opening, and the door is vertically boarded with a plain fanlight. The roof is piended in Scotch slate and has a ridge vent. This structure was probably originally a stable.

The property features gatepiers made of square-section droved ashlar with chamfered edges and a pyramidal cope. There is a lintelled pedestrian gateway to the left, with more recent wrought-iron gates. The garden walls are approximately six feet high, constructed from sandstone rubble with a rubble (Galloway) cope.
