Kingsley Park Middle School

This is a school building dated 1915, designed by Sharman and Archer of Wellingborough and constructed by J G Pullen and Son of Northampton at a cost of £28,735. The school was originally the Northampton Grammar School for Girls. It is constructed of red brick in English bond with ashlar dressings. The roof is hipped, covered in plain tiles, and has a deep wooden eaves cornice with modillion detail. Brick axial stacks are topped with moulded stone caps, along with two central ashlar stacks.

The building comprises a long front range, a parallel main hall range at the rear, and two rear wings. The design is in a Wrenaissance style. The front elevation has a basement and two storeys, while the rear has two and three storeys. The south front has 9, 3, 3, 3, and 9 bays, with the central nine bays projecting and featuring stone pilasters and a deep frieze decorated with wreaths. The central three bays further project, topped with an open segmental pediment resting on consoles, featuring a dated cartouche and festoons in the frieze. All windows have keystones; the central three bays have moulded archivolts, and the first floor centre window has a voluted canopy with a large keystone and festoons. A central doorway is topped with an open pediment on consoles, above a semi-circular fanlight and panelled, glazed double doors. The lower flanking nine bays have keystones, stone cills, and brick aprons to the windows. Above the centre is a wooden cupola with louvred sides, corner pilasters, ball finials, and a finial over the dome. The rear hall range has round-headed clerestory windows and pedimental gables over a round-arched rear doorway. The rear wings are gable-ended. All windows are sash windows with glazing bars and top-opening lights.

The main hall contains a balcony arcade on the south side with iron balustrades and pier pilasters with consoles breaking the cornice. Similar consoles are present on the window piers on the north side. The hall has a segmentally vaulted plaster ceiling and a panelled dado. The entrance hall also features dado panelling and round-headed arches with round window lights. The roof over the "seminar room" displays exposed arch braced trusses. There is a panelled library.
