I built a replica of a skyscraper in Frankfurt, Germany called “Messeturm” when I was in high school. I saw it in a book about architecture and was intrigued by the façade design, particularly the curtain wall system as well as the overall geometry throughout. The model is made primarily out of posterboard and other sturdy paper-based materials. It is my most detailed model to date, with individual evenly placed window pieces and mullion layouts represented.
