The book is an undergraduate Architecture history. This thesis is not a study of the anatomy of architecture or its physical form. It does not pose a question of tectonics nor does it study the materiality of buildings. Instead, this thesis seeks to capture and transcribe the experience of these spaces that are often unacknowledged. It is a study of the chemistry of an architectural space as it is created through three stages of drawings: the Twin Structures, the Connections and the Memories.
