The Old Manse, Hallidays Park, Selkirk

The Old Manse, located in Hallidays Park, Selkirk, is a mid-19th century house that has undergone later alterations and additions. This two-storey, three-bay classical house has a rectangular plan and features a lower two-storey addition to the northeast and a modern conservatory to the southwest. The building is constructed of squared whinstone with dressed red sandstone details on the northwest side, whinstone rubble with dressed red sandstone on the southeast, and harled surfaces on the southwest and northeast elevations. Notable architectural details include a base course, raised quoins, and eaves courses.

On the northwest elevation, there are two ashlar steps leading to a deep-set panelled door at the center, which is topped by a border-glazed rectangular fanlight. This door is framed by a partly cement-rendered pilastered and corniced doorpiece, with a window above on the first floor. Each flanking bay has a window on both floors. To the left, there is a whinstone rubble addition that is set back, featuring a bipartite dormer to the right of center.

The southeast elevation is asymmetrical, with a stair window at the center and windows in each flanking bay. There is a small window on the first floor between the center and the bay to the right. A three-bay addition has a door at the ground level of the outer bays, with a window to the left of center at ground level and a gabled window breaking the eaves at the center on the first floor.

On the southwest elevation, there is a window at ground level in the left bay, and a door to the outer right leads to the modern conservatory that projects from the building. The glazing is modern, and the roof is a platform with a piended slate covering, featuring a flat-roofed dormer in the outer bays of the southeast elevation. The side elevations have wallhead coped stacks.

The interior was not seen during the last inspection in 1995. The boundary walls consist of a whinstone rubble wall topped with rounded ashlar coping.
