Architectural debate is a dialogue between analytical curiosity and sensuous functionality, rather than the conditional opposites of abstraction and the concretely realizable. The appreciation of space is at the centre of the study: Spatial appreciation as the expression of a mental attitude, the understanding of space in different cultural epochs, space in test structures. Architecture originates from wherever a stress field is established between a space as physically comprehended through material structures and space as experienced through feelings. A separate key topic in this context is especially dedicated to the use of artificial lighting or artificially reflected natural light. In addition, the theoretical discussions accompanying design considerations are investigated in depth.
