The challenge here was to develop a development and use concept that would blend architectonically into the existing perimeter block development, on the one hand, and would complement and enhance its surroundings with a site-adequate mix of use types, on the other hand. In the blocks of Mannheim, living, working and day-to-day life blend into a homogeneous whole. From the start, the new property was supposed to look like an integral part of the Planken high street shopping precinct. This was achieved through a structurally and functionally smart global solution. The six-storey building (with another three basement floors to be added) occupies the entire D3 block in downtown Mannheim. It accommodates more than 130 flats and more than 30 retail units.
