Ormiston Manse, Main Street, Ormiston

The property comprises a 17th-century house that was substantially altered in 1779. At this time, the original first floor was removed and replaced with a new first and second floor, and a three-storey projection was added to the rear. Simultaneously, additions were made in the re-entrant angle at the rear to create a service court. Further alterations and a two-storey addition to the rear projection were undertaken around 1850, extending at right angles. The construction is primarily rubble, with harl pointing and squared and snecked work in the 19th-century additions. Relieving arches are visible above the windows of the 17th and 18th-century portions, and ashlar dressings feature chamfered arrises.

The east-west wing has three bays facing south, grouped towards the centre. Ground floor windows have been altered. The first floor has tall windows, while the second floor windows break the eaves within gabled dormerheads, a feature of the mid-19th century. The end elevations are gabled, with a gabled ashlar porch added to the east elevation in the mid-19th century. This porch has a mannered lintel over the doorway and chamfered reveals. The first floor has windows, and the second floor has a window to the south bay of both the east and west elevations.

A three-storey gabled projection was added to the north elevation of the earlier block in 1779. Around 1850, a two-storey gabled addition was built at right angles to this projection, extending eastwards. This addition has a blank gabled elevation to the east and tripartite windows on both the ground and first floors of its north elevation. The south elevation has two bays, comprising a gabled bay with a stack and a bay with single windows on the ground and first floors.

A gabled single-storey and attic addition is located in the re-entrant angle at the rear, and a pentice-roofed addition extends from the earlier house, forming a narrow passage to a rear doorway, currently accessed by a modern lead-to porch. Small-pane glazing is present in sash and case windows, with plate glass used in three windows on the south elevation. Chimneys and stacks are visible, and the roof is covered in grey slates.

A 19th-century stable range is located to the northwest of the house. It has a rectangular plan, with a taller central block flanked by lower blocks on the north and south sides in a symmetrical arrangement. A garage entrance has been inserted, and the west elevation is blank. Doorways are present in each block on the east elevation. Garden sheds, dating from the 18th and 19th centuries, are arranged in an "L" shape, incorporating an earlier range with a piended roof at the corner and pantiles, alongside a taller gabled range with grey slates. Machinery doors are present in both blocks. Decorative railings are retained on a coped rubble base to the southwest of the house (the roadside railings having been removed and replaced with a harled wall), alongside pyramid-capped ashlar gate piers, rubble retaining walls, and a walled garden to the northwest.
