Hurworth House Boys' Preparatory School

Hurworth House Boys' Preparatory School is a house dating from around 1730, now serving as a boys' preparatory school. It is constructed of brick with stone dressings, featuring a header-bond front and a Flemish-bond rear. The building has a graduated green slate roof with brick chimney stacks.

The entrance front is three stories high and has three bays, complete with a plinth, raised-and-chamfered quoins, sill bands, and an eaves cornice. The central entrance features a six-panel door and a radial fanlight within an open-pedimented stone doorcase, which has engaged columns with fluted capitals and dosserets. There are canted brick bays on either side of the central bay. The windows have flat-faced surrounds, with twelve-pane sashes on the ground and first floors and square six-pane sashes on the top floor. The low-pitched roof has stone-coped gables and end stacks.

The rear of the building is also three stories high with three bays, featuring a plinth, sill bands, and an eaves cornice. The central entrance at the rear has a partly-glazed four-panel door and an overlight with patterned glazing in a rusticated stone doorcase with engaged fluted columns. Above the door is an elongated sash window, and there is a round-arched sash window on the top floor. The rear also has canted brick bays flanking the central bay, with sashes in flat-faced surrounds.

Inside, there is a dogleg staircase comprising four flights plus a landing rail, featuring a moulded closed string, square newels, a ramped square-sectioned handrail on thin turned balusters, and a ramped dado rail. Late 19th-century and early 20th-century additions on both returns are not considered of special interest.
