10, 12 Main Street, Newhaven, Edinburgh

10 and 12 Main Street in Newhaven, Edinburgh, is a mid-18th century building that was recast and converted by Ian Lindsay & Partners around 1970. It is a low, two-storey, four-bay rectangular house that forms the end of a terrace. The exterior is harled and limewashed, featuring raised and painted concrete surrounds around the openings. There is an exterior stair with timber railings leading to the first floor.

On the south elevation facing Main Street, the stair is located to the right of the center. Below the stair, there is a single window set in a recess, and above, a boarded two-leaf timber door leads to the first floor. A boarded timber door provides access to a storage area beneath the stair. The outer right bay has single windows on both floors, while the remaining bays are regularly fenestrated with windows at both the ground and first floors.

On the north elevation facing Peacock Court, there is a timber boarded door at ground level in the central bay. The ground floor is regularly fenestrated, with single windows in the outer left and right bays on the first floor.

Both elevations feature 12-pane timber sash and case windows. The roof is machine-made red pantiled with a grey slate easing course and raised skews. There is a harled and coped apex stack on the east side with circular cans, a coped ridge stack on the west with octagonal cans, and a squat and coped wallhead stack on the south in the outer left bay with an octagonal can.
