St Joseph's R. C. Boy's School, 126 Blackness Road, 124A, Dundee

St Joseph's Roman Catholic Boys' School, located at 126 Blackness Road in Dundee, was designed by James H Langlands with assistance from W G Lamond and built between 1905 and 1906. This school features Art Nouveau details and is constructed from snecked bull-nosed rubble with ashlar dressings. It has a four-storey stepped frontage, highlighted by a taller stair tower facing the street. The entrance originally had a door with a semi-circular hood, which has since been converted into a window. The building includes mullioned windows with two and four lights, and curvilinear parapets atop the tower and central bay.

Adjacent to the main structure is a two-storey, six-bay classroom block that boasts large arched windows with original mullioned and transomed glazing. The block has a piended roof featuring a central louvred ventilator, broad eaves, and a flat dome. An extension designed by Wm Friskin was added in 1933, which is a two-storey polished ashlar structure with five bays set between splayed pilaster buttresses that rise from a plinth. The left three bays contain four windows each, while the right two bays have smaller three-high windows on each floor. The original stair tower also has a polished ashlar face.

Inside, the school features a plainly tiled square stairwell. The corridor leading to the classrooms is illuminated by large arched windows similar to those on the west elevation, with a 1933 concrete and brick extension to the east. The rear of the 1933 block opens to a yard at ground level, while the first-floor corridor is cantilevered out on a concrete floor.

The original block is adorned with wrought iron Art Nouveau railings in the re-entrant area, and steel railings were added to the playground and reinstated along Blackness Road in 2002.
