The site “Am Mühlenberg” was developed in the 1950s in the typical style of post-war modernism. We modify the existing structure with the help of adaptors to achieve a new urban ensemble with clearly defined streets and courtyards. The existing buildings remain legible and functional. The heights of the new buildings are oriented by the adjacent houses or result from urban planning considerations to define the street space. At the same time, clearly discernible outdoor typologies are created. These include rather introverted but walk-through courtyards of different character, a continuous alley system, partly car-free, partly as residential paths with visitor parking spaces, and a sequence of distinctive public micro squares.
