The project is situated in the city of Vienna, Austria, and attempts to connect two divided quarters of the city. Over the years inhabitants from both sides of the city have become more disconnected. By retelling the story of Maurice Ravel's 'La Valse' in an architectural sculpture, I will attempt t reconnect the two groups of people. Using basic music- and color theory I will translate his musical ideas into architectural form. Musically, the structure will translate into an architectural circulation diagram, where volumes are placed accordingly. A vector field will establish a relationship between the volumes. Material distribution and detailing will be informed by the musical color, and will have input by acoustics, porosity and lighting. Finally I will reflect upon the parametric design process - how it has helped the flow of data and design, and what new opportunities it may bring in the future.
