Seymour Hill House, Yew Tree Walk, Dunmurry, Co. Antrim, BT17 9PG

Seymour Hill House is a late Georgian house built around 1790, situated off the Kingsway just south of Dunmurry at the crest of Beech Tree Crescent, north of Seymour Hill Housing Estate and east of the now-named Seymour Hill Industrial Estate.

The house is a two-storey, five-bay rectangular plan with a basement and attic storey. It features a hipped slated roof with two very large rendered chimney stacks, each crowned by seven tall octagonal clay chimney pots. The eaves have an overhanging soffit with paired moulded console brackets set in front of an ogee moulded cornice.

The walling is rough finished render with evidence of faded ruled and lined render underneath. The quoins are heavily vermiculated and doubled at the front, with a rusticated basement level. Windows are single glazed 1/1 timber sliding sash with horns (all replacement), featuring large stone cills and moulded stone surrounds with frieze and projecting cornice above. The guttering is uPVC ogee in black with extruded metal downpipes painted to match the walls. Paired pie-crust dormer windows project from the east and west elevations, with three modern roof lights over the principal elevation.

The principal south-facing elevation is symmetrically arranged. The front porch is accessed by six paved steps flanked by a pair of naturally finished stone balustrades. The porch, originally featuring a front door and side windows, is now an open broken-pedimented portico with a half-circled arch with moulded surrounds, flanked by paired acanthus columns supporting an entablature with swag mouldings fixed to the frieze. The principal door is six-panelled timber with a half-circle fixed light above and moulded stone surrounds. Two windows flank the entrance with five windows above on the first floor. The central first-floor window has additional decorative stone moulded surrounds in the form of consoles supporting the cornice and profile scrolling above the cill level.

The east-facing elevation is principally symmetrical with paired windows at each floor level and dormer windows projecting from the roof, with the chimney stack centrally located at the apex. The west-facing elevation replicates the east elevation. The north-facing rear elevation is symmetrically arranged with the original rear entrance located left of centre and a new opening for an additional entrance right of centre. The central bay windows are offset at different levels to function as stairwell lights. This elevation has less detailing, with no window surrounds or eaves bracket details.

The approach is set among trees and shrubs, with a bleach green located to the southeast. A small tarmac car park is situated to the front, with a road leading around to the rear on the left-hand side. Original random rubble stables and outbuildings are located just to the north of the house, with modern two-storey accommodation encompassing the rear elevation. Views extend southeast towards the former bleach works, with remaining southerly views overlooking housing.
