Shrewsbury House, including boundary walls and gates, pergola, terrace walling, steps and gazebo

Shrewsbury House is a substantial two-storey house with attics, built mainly of red brick in stretcher bond with stone dressings. The house is aligned north-east to south-west, with a single-storey service end to the south-east. It is roofed with hipped tiles and features a projecting wooden modillion cornice, three tall moulded brick chimneystacks with round-headed panels, and windows that are principally wooden multi-pane mullioned and transomed casements with rubbed brick voussoirs.

The plan is symmetrical. The north-west front, which serves as the entrance elevation, displays eleven bays. The central five bays are recessed and contain three hipped dormers, five first-floor casement windows, taller ground-floor casement windows, and a central doorcase with round-headed fanlight and double doors. A large Ionic portico with balustraded parapet projects in front of these central bays, with a black and white marble floor beneath. The end three bays on each side project forward and have rusticated stone quoins. The single-storey service end attached at the south has three mullioned and transomed casements.

The north-east end elevation has four unevenly spaced first-floor casements. The ground floor contains two larger similar windows to the centre, curved end bays with moulded stone cornices, and central French windows with rectangular fanlights featuring intersecting glazing bars, flanked by narrow side-lights.

The south-east or garden front mirrors the north-west elevation with eleven bays. The recessed central five bays contain three hipped dormers, first-floor casement windows, and a central curved bay to the ground floor with French windows and rectangular fanlight, flanked by two narrower doors on each side. The returns to the projecting end bays have round-headed niches. A curved stone Ionic portico with balustraded parapet serves the first floor, with a black and white stone marble floor. The projecting end three bays feature mullioned and transomed casements, taller on the ground floor. The service end has two windows and two doors.

Associated with the south-east side of the house is a path of York stone paving and a brick pergola with a low wall topped with tiles and piers featuring tiles-on-edge and wooden cross beams. This connects to brick terrace walling in English bond with terracotta capping, incorporating square piers and circular stone steps that run northward, terminating in a brick gazebo with hipped tiled roof, round-headed multi-pane windows, and a round-headed entrance on the north-west side. The pergola and terrace walling also connect to a brick perimeter boundary wall, approximately six feet high, built in English garden wall bond with splayed base and pilasters at regular intervals. On the south side, three rusticated brick gate piers enclose a double vehicular gate and single pedestrian gate of cast and wrought iron with elaborate scrollwork to the upper panels and overthrows. Similar boundary walls appear on the east and west sides, while the north side features a low brick wall surmounted by iron railings.

The interior of the house begins with a panelled entrance hall containing a marble fireplace and a plastered ceiling with a circular high relief carving of fruit and paterae. The northern large reception room, probably originally a drawing room but used as a library from the 1930s, has plank and muntin oak panelling, two four-centred arched stone fireplaces, and a plastered ceiling with strapwork design, moulded cornice, and wall panels above the panelling. The central south-east facing room, probably a morning room, features an Adam style plastered ceiling, panelled walls with dado rail, and a wooden fireplace with central panel decorated with urn and scrollwork, end sheep's heads, and pilasters over a marble grate. An adjoining room to the south, probably originally the dining room, contains early 18th-century style oak panelling with dado rail and a marble fireplace with eared architraves. A further room on the south side of the north-west front has a wooden fireplace and overmantel with Ionic columns, plastered cornice, and a ceiling with high relief circular moulding; this was probably originally a study. Former service rooms contain tiled dado rails and a service staircase.

The main staircase is constructed of oak with a central well, turned balusters, square newel posts, and dado panelling, giving access to the upper floors. First-floor rooms retain wooden fireplaces mainly with marble interiors, though a small room adjoining the staircase has a painted tiled interior. Former bathrooms feature tiling: one is decorated with ribbons and grape garlands, another has two-tone green tiles with embossed swags. Attic floor rooms retain smaller wooden fireplaces with blue or beige tiles. Panelled doors and wooden parquet floors survive throughout the building.
