Pembury County Primary School (Old School) Including Front Boundary Wall

The building comprises a school and former master's house, dating from circa 1870 to 1880. Constructed in Flemish bond red brick with cream and yellow-coloured sandstone dressings, decorative black brick, brick stacks, and chimneyshafts, the roofs are tiled with peg tiles, with cross roofs featuring crested ridgetiles pierced by trefoils.

The building is laid out as a school to the left (south) with a 5 or 6-room plan and axial stacks, incorporating a crosswing projecting both forward and back at the left end, and a pair of rear wings projecting to the rear towards the centre of the building. To the right is the master's house, with a 3- or 4-room plan and a projecting wing adjacent to the school, its axial stack backing onto the school building. The school is primarily single-storey, while the master's house is two-storeys in height.

The architectural style is Victorian High Gothic. The front elevation is enriched by horizontal bands of yellow-coloured sandstone sandwiched between courses of black brick. The school front features five tall, arch-headed windows, two with trefoil heads in the gable end of the left crosswing, another with a plain 2-centred arch head in the main block, and a pair further right, separated by three buttresses. All windows contain timber windows with Decorated tracery, featuring patterns of coloured leaded glass; the gables are topped with plain bargeboards, though early photographs indicate they were originally collared and filled with open quatrefoils. A 2-centred arch doorway, with an internal porch and plain plank door, is located to the right of the paired windows. A gabled half dormer above the doorway helps to balance the front façade. The forward-projecting wing of the master's house has square-headed mullioned windows beneath a monopitch roof over a shaped brick cornice. To the right is a two-bay arcade, featuring a column with a stiff leaf capital and 2-centred arches leading to a recessed porch and plain plank door. A half dormer with a hipped roof and finial sits above the arcade; other finials were present on the school building in early photographs. The remaining sides of the house and school are plainer in style. Early photographs also depict a spire-like belfry on the ridge of the school roof. The interior was not inspected.

A low brick boundary wall with shaped brick coping runs along the strip of ground in front of the school. It is bordered by square gate posts with pyramid caps.
