The urban planning concept for the “Riedberg Variations” draws on the agricultural past of the city of Riedberg creating associations with orchards, espaliers, dirt roads, dry stone walls, hedges, and groves
The urban development plan is organized around the form of a leaf blade with a central rib and side ribs. Streets in the west wing are curved in order to relax the typical planning grid. The plan features paths throughout the quarter that is naturalist and organic creating a dialogue with the site and the architecture. Wild and native gardens are planted throughout to create a park-like setting while absorbing heat and cooling the site.
When developing the building types, the aim was to achieve a high degree of diversity for the 305 residential units, taking into account economical construction. The structures fit into harmonious ensembles and yet are individually designed. There are three typologies to be distinguished that are shaped by their respective location and are characterized by a completely unique design language:
The townhouses along Konrad-Zuse-Straße take up the street alignment and at the same time create a unique relief of diagonal wall folds, terraces, and openings.
The 3–4-story apartment houses on terraces are divided into three basic types (small – medium – large), which can be varied by shortening or mirroring them. Inspired by the folded and staggered dry stone walls of vineyards, they adapt to the topography and at the same time dramatize it.
The city villas on the Topographischer Weg are lined up along the park. Two different types alternate with each other. By means of the slightly different orientation of the building, the appearance varies and different openings are created into the interior of the block.
