Design a structure that captures the essence of Roman architecture through the use of classical proportions and harmonious design principles. Imagine a building where every element is meticulously measured and balanced according to ancient Roman ideals of symmetry and proportion. The layout features a series of carefully aligned spaces, from grand halls to intimate alcoves, each designed to create a sense of order and beauty. Facades are divided into modules using pilasters and entablatures, while the height, width, and depth of each part are proportioned to achieve perfect harmony. This adherence to classical proportions not only ensures aesthetic unity but also resonates with the timeless elegance of Roman architectural wonders.
