Southleigh Park, House (excluding attached 1983 corridor and office building)

Southleigh Park is a mid-19th-century country house, now a commercial establishment, located on Horndean Road in Emsworth. The listing excludes an attached 1983 corridor and office building.

The house is constructed of coursed, knapped flint with flint galleting, beneath a hipped Welsh slate roof. It is a two-storey building arranged over seven by three bays facing south, with a five-bay west-east wing and a two-bay link projecting from the rear left corner.

The south-facing garden elevation is the principal facade, divided into one and six-bay sections. The six-bay section features pilaster buttresses that rise as turrets, with a central two-bay bow flanked by corbelled circular turrets. Pale-grey flint hoodmoulds, a parapet band, and vertical bands to the buttresses provide decorative emphasis. The parapet and turrets are embattled; the parapet to the bow and its flanking turrets were reduced in height by approximately one metre in 1983. Windows are square-headed with wooden mullions and transoms and foiled glazing bars to upper lights, set in reveals with dentilled heads. Soffits comprise iron plates with decorative panels filled by flint shards. Ground floor windows feature four lights to bay one and the bow, otherwise two lights; most have French windows. Tall chimney stacks with coupled shafts, chamfered plinths and embattled caps punctuate the elevation.

The right return (entrance elevation) has a lower added bay on the right and a single-storey three-bay embattled porch across the original elevation. The entrance features raised pilasters, a heavy moulded wooden console bracket supporting the hood, and a replacement small-paned glazed double door. A first-floor window has been inserted. To the left of the entrance are two tall replacement windows with small-paned glazing.

The left return (west elevation) has two right-handed projecting bays: the left one is canted, with ground floor windows of two and four lights. The leftmost bay features a ground floor canted bay with French windows and a flat roof forming a first-floor balcony with access from a canted bay window. A stepped link to the wing has a door leading to a former conservatory that ran alongside it; only the decorative tile border to the floor paving and the chamfered dwarf brick walls survive. The wing has a central three-bay section projecting slightly with French windows on the ground floor, corbelled corner turrets, and a parapet stepping up at the centre. The left bay is blind. Ground floor windows have pointed arched glazing bars to upper lights.

The interior retains significant original features despite 20th-century alterations. The entrance porch leads into a circular vestibule with a floor of black and white polished stone set in a radial pattern. The entrance door has cusped panels, etched glass, and foiled overlights. The entrance hall features a stone flag floor, quasi-marble Ionic columns, and tongue and dart cornices. The principal stair is an open well with stone treads and a replacement balustrade. Principal rooms were refurbished in the 1930s following fire damage, but original doors, reveals and window shutters remain. The Billiard Room in the rear left corner retains its wood-block floor, coloured glass to the upper lights of windows, a compartmental ceiling with decorative bosses, and a cornice with shields and floral bosses. The service stair retains its wooden handrail with spiral curtail, stick balusters, columnar newels, moulded tread ends, and panelled cupboards at the base, possibly original. A back doorway retains radial glazing bars to its fanlight. The first floor was substantially reordered during a 1970s office conversion, though small sections of original well-moulded cornices survive, and the room above the Billiard Room retains similarly moulded skirting boards and architraves with floral corner panels.

A rear left corner of the main block connects via a 1983 brick and glass corridor (not included in this listing) to the Clock Tower building and to a 1983 brick and glass office building (also not included).

The clock in the Clock Tower building is dated 1840 and may indicate the date of the house.
