Hertingfordbury School Old School House

Hertingfordbury School, also known as the Old School House, is a school building that was partially converted into a dwelling around 1850. It was endowed by H. Cowper. The structure is made of red brick with white brick dressings and features a fishscale patterned machine-tiled roof. The building has a half-H shape, is one storey high with attics, and includes a three-bay central range that has a gabled projection at the center. This projection has a gauged brick four-centred arch above a cross casement window flanked by tall lights, with two additional lights in the gable. All windows have slightly cambered heads and chamfered surrounds, with diamond-patterned panes. The eaves are dentilled brick.

The outer bays of the central range contain six-light mullion and transom windows. The wings extend forward at the ends, creating four-bay re-entrant elevations with two four-light mullion and transom windows toward the rear. The front bay features six-light mullion and transom windows with plank and muntin doors in between, topped with diamond-pane fanlights. Above the entrances, there are two-light dormers with corbelled out features and kneelers to coped gabled heads. The front gable ends of the wings have tripartite transomed windows on the ground floor, arranged in a 2:4:2 light configuration, with two lights in the attics. The gable parapets have shaped kneelers with flattened ends.

On the ridge of the right wing, there are two cross axial stacks with triple chamfered shafts. The wings have three-bay returns with altered openings, including an entrance on the right end. The gable ends of the main range at the rear extend slightly further and feature three tall lights, similar to the front. The interior has not been inspected. A Victorian posting box is built into the wall of the left front gable end. In front of the building, there is an enclosing yard with walls extending from the gable ends of the wings, about one meter high, featuring a dentilled course below the coping, buttresses, and small stone-capped end piers.
