Castle House

Castle House, now part of a school, is a large house with late 18th-century origins, partially rebuilt around 1900 by A. Hill Parker and Stokes Brothers following a substantial fire, with later additions and alterations. The exterior is a combination of painted stucco, painted rough-cast and painted brick, stone dressings, and tile-hung second-floor sections. The roofs are covered in plain clay tiles, with a hipped roof to the right, and feature modillioned eaves and bracketed eaves to the gable of a canted bay. Brick stacks are present on the left, with stucco stacks on the right, all featuring oversailing details and decorative pots.

The house follows a double-fronted, double-depth plan. A through-passage to the right of the ground floor is flanked by a sandstone wall. The building is two and three storeys high, with an attic. It has four first-floor windows. Stone detailing includes all sills and a moulded string above the ground-floor windows. A two-storey range is set back slightly to the left, and a full-height canted bay features mullions in a 4/1:4/1:4/1:4/1 format. The main range windows are 6/6 sashes, with ground and first-floor windows flush with moulded architraves. Second-floor windows are also 6/6 sashes. The central entrance door is six-panelled, with the upper pair glazed and raised and fielded detailing to the centre, and flush-beaded lower panels. A three-pane overlight sits above, and the doorcase features "Tower of Winds" style columns, frieze, and cornice. A further door to the passage on the extreme right has six raised and fielded panels with bolection moulding, a moulded architrave, and a small cornice. A gabled dormer is positioned above, with paired 6-pane side-hung casements. Further ranges are visible to the left return and to the rear. A lower portion of the right-return wall is sandstone ashlar, forming part of an earlier structure.

Inside, late 18th-century joinery is evident, including panelled doors in moulded timber architraves. Decorative plasterwork from the late 19th century is present on the first-floor right. A staircase and fire surrounds showcase Art Nouveau detailing from around 1900.

Castle House is part of a significant group of buildings forming the setting for Worcester Cathedral to the north. The rear boundary wall for numbers 2-6 College Green is part of the Monastic Precinct Wall, a Scheduled Ancient Monument.
