Interior of the staircase

In the twin stair towers of Scotland Street School Mackintosh left a void between the curved outer screen of glass and the staircase, two elements that were later united by Walter Gropius in the Fagus Factory (1911), Alfeld-an-der-Leine, Germany. At Scotland Street the separation permits an uninterrupted upward view through each tower to the traditional carpentry supporting the conical roof. The towers and the tall ranges of windows between them have their sources in the 16th-century Falkland Palace, Fife, which Mackintosh sketched (Hunterian Art Gallery, University of Glasgow).
