Former Stable Block immediately east of Wrest Park House

The former stable block, dating to the 18th century, is located immediately east of Wrest Park House. It is constructed of yellow brick with stone dressings and slate roofs, with a symmetrical courtyard plan forming a U-shape, with additional extensions to the east and west wings, although the original plan has been disrupted by later additions.

The stable block comprises the west, north, and east sides of the stable courtyard. The principal north elevation features a pair of mansard-roofed pavilions that flank a central carriage entrance, which has a segmental arch with moulded decoration and double doors with moulded panels. A moulded cornice and shallow stepped parapet sit above. The flanking two-storey ranges have 20th-century casement windows inserted below plain concrete lintels, and the mansard roof extending between the pavilions has been altered. These pavilions have advanced banded brickwork to the corners, imitating rusticated quoins, segmental headed blind and glazed window openings, a deep storey band course, and a moulded cornice. The courtyard elevation of the main north range has a slightly advanced three-bay section containing the inner portal, flanked by three-bay ranges to the east and west. Seven-bay wings to the north range form the east and west sides of the courtyard, with five-bay return ranges on each side, each having a slightly advanced central bay. The main courtyard elevations have door and window openings set beneath shallow segmental arches. Upper floor window frames are set within the brick infilling of taller openings which terminate at a narrow storey band. The former ground floor stable doorways have rectangular overlights and flanking windows, originally fitted with small-paned cast iron frames. These survive at ground floor level in the east elevation of the west range, and the south elevation of the return range to the east wing. Later 20th-century door and window frames have replaced the original frames in most areas, and some openings have been adapted to receive narrower frames. The five-bay south elevations of the return ranges have wide segmental arches containing door and window openings, some of which have been altered, set within brick infill.

The interior of the building has been progressively converted to office use since the mid-20th century, and no original stable interiors survive. Significant alterations have been made to the original plan form, reflected in changes to the external elevations and the addition of many new window openings throughout the complex.
