Description
The Longcastle Schoolhouse, built around 1840, consists of a range of buildings featuring a two-storey, three-bay schoolhouse that is connected to a single-storey T-plan schoolroom range. The exterior is made of painted rubble with raised painted margins. Most of the windows are sash and case style with 12-pane uPVC glazing.
The schoolhouse itself is two-storey and has three bays, with a prominent central bay that is harled and added later. The windows, set within raised painted margins, are all sash and case with 12-pane glazing. The west gable has four hoodmoulded windows, with the first-floor windows being blind. The roofs are covered with slate, and there are sandstone ridges and skews, along with corniced end stacks and octagonal cans.
The schoolrooms, which are now used as workshops, form a single-storey T-plan wing that adjoins the house to the north. The north elevation has five bays and features two gabled brick porches. The west gable includes a hoodmoulded bipartite window. The roofs are also slate, with sandstone skews and ridges, and the west gable is topped with a ball finial. There are replaced metal ventilators over the schoolroom and coped axial stacks.
