Greyabbey Primary School, 3 The Square, Greyabbey, Newtownards, Co. Down, BT22 2QA

Greyabbey Primary School is a single-storey gabled school of 1887, constructed in basalt rubble with Scrabo stone dressings. Located on the south-east side of The Square in Greyabbey, it is listed Grade B1 for its architectural and local historical interest.

The building was originally L-shaped. The front north-west elevation contains the long arm of the original L, featuring a large gabled bay to the north-east side and a smaller central gabled porch. The porch contains a timber-sheeted double door set in a Scrabo stone Tudor arch with intricate Arts and Crafts-like carved decoration above. A decorative plaque above the arch reads "V. R. Jubilee 1887" and bears a crown and shield. Label moulding surmounts the carving and plaque. On either side of the porch are small narrow windows with Scrabo stone dressings set on a cill band, also in Scrabo stone. The porch is topped with a Bangor blue slated roof with overhang and clay ridge tile finial.

To the left of the porch are paired mullioned and transomed windows with small upper openers and Scrabo stone dressings. To the right are two pairs of similar windows, separated by a chimney breast with decorative carved shield in Scrabo stone. At the far left of the front facade is a large gabled buttressed bay with a mullioned and transomed window, larger than those to the right and featuring label moulding. This window rests on a Scrabo stone cill band, which runs beneath all windows on the original facade. Above the window, towards the gable apex, is a small narrow louvred opening with Scrabo stone dressings. The gable roof has an overhang and finial.

The south-west facade comprises a similar gabled bay to the left (though with a slightly smaller window) and the south-west side of the shorter horizontal arm of the L, which contains a window matching the bay pattern but without label moulding. The section facing Portaferry Road is behind a rubble wall. The north-east elevation has two widely spaced windows, similar to those on the front, with a chimney breast in the centre.

The rear elevation, facing the school yard, has been substantially altered. The roof pitch has been extended to cover a modern lean-to corridor with a brick-built extension and large modern segmental arch-headed windows, obscuring most of the original L-shape's interior. At the south-west gable end of the original building, the corridor projects beyond and connects to a recently constructed gabled dining hall in matching brick. The remaining original south-west gable itself has a large gabled window. At the far right of the rear is a large original gabled bay with a relatively small mullioned and transomed timber window, without Scrabo stone dressings or cill course.

All roofs on the original section are pitched with Bangor blue slates and clay ridge tiles. The modern sections have fibre cement slates. Four tall chimney stacks, part rubble and part yellow brick, rise from the original roof. Cast iron rainwater goods serve the original school facade, with aluminium fittings on modern sections.

The school opened in 1887, as commemorated by the V.R. Jubilee plaque, marking Queen Victoria's golden jubilee. The lean-to corridor and dining hall were added around 1988, though they may have replaced earlier structures. Prior to this school's construction, local children were educated at a schoolhouse at the north end of the village near St. Saviour's Church, with infants attending what may have been housed in the Church of Ireland parochial hall on the opposite side of The Square.

The listing extends to the house and boundary wall to the south.
