This project is a dynamic exploration of the relationship between a historic, neoclassical building and a contemporary addition within the context of a rapidly developing neighborhood in Frankfurt. While designed in a contemporary style, the addition creates a cohesive whole with the existing landmarked building by corresponding to the volume, rhythm, and proportions of the original. It also takes on the generous floor-to-floor height of the prewar structure and the angular shape of its mansard roof. The addition departs from the neoclassical design of the existing building through the use of a sculpturally folded concrete façade punctured by large openings, balconies and loggias, and the playful use of color. 1100 is also working on the renovation of the existing building.
