 Gillespie, Kidd & Coia employees Isi Metzstein and Andy MacMillan developed a radical design in which the old house would become professorial accommodation, and around it would wrap a striking new main block, a convent block, a sanctuary block and a classroom block.The old house thus became one side of a quadrangle, creating a bold juxtaposition between old and new buildings.Determinedly modernist, brutalist and owing a huge debt to Le Corbusier, the seminary is widely considered to be one of the most important examples of modernist architecture in Scotland.
