Scotland Street School In 1901, on the retirement of John Honeyman, Mackintosh became a senior partner in the firm, which was then known as Honeyman, Keppie and Mackintosh. In the same year he began work on the design of the Scotland Street School. The building is distinguished by a simple plan, symmetrically arranged to segregate the sexes and twin three storey staircase bays infilled with windows. Decoration is minimal, a reflection of both a restricted budget and the functional nature of the building.

However, Mackintosh did display his usual thoughtful approach to detail that he showed in smaller, domestic commissions. In the children's cloakrooms, wet clothing was warmed and dried by hot pipes running behind the coat hooks. The classrooms are south facing, while the drill hall and domestic science room face north, to provide appropriately cooler environments.
