Evolution of the boundary : theories of threshold, poché and stereotomic design, and their manifestation in the work of Henri Comrie

The design of boundaries in architecture has a rich history that provides intellectual nourishment for a reconsideration of the relationships between city and nature, city street and building and the transitions within buildings. This article will describe the condition of boundary in place-making and architecture by sketching a brief theoretical and philosophical background of approaches to
its formation. Following this, the formal expression and articulation of boundaries in urban and architectural settings will be outlined. Then, through the description of selected examples of the urban and architecture outputs of the award-winning South African architect and urban designer, Henri Comrie, real-world examples of boundaries will be contextualised and described.
