Sisters' House and School to North of Church of St Columba

Sisters' House and School, located to the north of the Church of St Columba, was designed by James Brooks and built in 1898. This two-storey and attic building features two bays and connects the School to St Columba's Vicarage. It is constructed of red brick with stone bands and dressings, topped with a high-pitched roof made of Welsh slate. The building includes a large dormer with a half-octagonal front, four grouped windows with carved cusping in stone lintels, and a pointed arched door with a hoodmould, which is broken on the left by a narrow window. Above the door, there is a staircase window, and three quatrefoils are positioned just below the eaves.

The School building, constructed in 1865, has been partly rebuilt due to war damage. It uses similar materials to the Sisters' House but features a simpler design. This two-storey structure has seven bays that are clearly expressed on the ground floor, with a different rhythm of two bays on the left, three in the middle, and three on the right above. It includes plain lancets with a continuous hoodmould, interrupted only by a slightly projecting chimney bay. The west window features an incised stone tympanum, while the ground floor has paired lancets with decorative brickwork in the tympana beneath pointed relieving arches with a continuous hoodmould.

The Sisters' House and School, along with the Church of St Columba, the Vicarage, the link building, and the forecourt railings, form a cohesive group.
