How do architects generate form? What are the implications of the interdependence of form and space? Architectural practice, due to its complexity and plurality, urges an aesthetic inquiry into the totality of architectural work. This book proposes a theoretical and conceptual framework for an aesthetic evaluation, understanding, and analysis of architectural work. It intersects three essential themes: architectural expression as the prevalence of the meaning of form, the uniqueness of spatial qualities as the content of the architectural work, and aesthetic experience as the essence of architectural creation.It aims to decipher the aesthetic ideal from a qualitative point of view and to reveal the reasoning behind the design approach, representing in that sense a link between the evaluation of the built design, and the clarification of the conceptual design. It intends to explain the built work from the creative process and to transform the conventional understanding of architecture from technical and technological perspectives, and economic, cultural, or social tendencies, through the aesthetic dissection of the correlation of form and space.The book does not offer definite answers but aims to unfold and integrate the discourse on form and space interdependence, as the fundamentals of the discipline, into contemporary architecture. "The Work of architecture [...], in its singularity, excavated within, it takes on a universal breath." Luciano Semerani.
